Botanic Endeavour 250 Trail Botanic Endeavour Trail - 600m | Botanic Explorers Trail - 900m Botanic Gardens Australia and New Zealand celebrates 250 years of the discovery of the flora of Australia’s east coast and New Zealand by western science in 1770 and over 40,000 years of traditional knowledge. Be an epic voyager for the day and discover some of the plants that Banks and Solander collected during their voyage along the east coast of Australia. Look out for the Botanic Endeavour 250 symbol to find what other plants were discovered during the voyage as you wander through the gardens. Botanic Endeavour 250 Our plants, our future Botanic Gardens and Arboreta throughout Australia and New Zealand (BGANZ) commemorate the anniversary ‘voyage of discovery’ onboard the barque Endeavour, during which Joseph Banks and Daniel Solander made a comprehensive collection of flora. Captain James Cook mapped the entire coastline of New Zealand in 1769 before traversing the east coast of Australia in 1770 from Point Hicks to Cape York. Pressings of over 520 new taxa unknown to western science were collected along the route up the east coast of Australia and these, along with thousands of botanical illustrations, somehow made it back to England in the face of shipwreck, waterlogging and the dank and humid conditions below decks. The rich abundance of diverse flora excited the botanic world and ultimately led to the settlement of the new colony. In Australia, 2020 marks the 250th anniversary of these discoveries. New Zealand celebrated this anniversary in 2019. Our Australian Indigenous heritage Prior to 1770, the Traditional Custodians of Australia lived in harmony with the land for over 40,000 years and discovered the ethnobotanic use for Australia’s native flora for food, medicine, tools, clothing and building materials. -
Hoya Australis Subsp. Oramicola (A Vine)
Advice to the Minister for the Environment and Heritage from the Threatened Species Scientific Committee on Amendments to the list of Threatened Species under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) 1. Scientific name (common name) Hoya australis subsp. oramicola (a vine) 2. Description Hoya australis subsp. oramicola is an evergreen, perennial vine with succulent leaves that grow to approximately 10cm long. Its flowers are cream coloured and fleshy, with flowering recorded during March and July. Fruiting occurs three to four months after flowering. 3. National Context Hoya australis subsp. oramicola is endemic to the Northern Territory. The subspecies is restricted to coastal monsoon vine thicket communities on Bathurst and Melville Islands, where it is known from four localities (Kerrigan et al 2004). The subspecies is currently listed as vulnerable under the Northern Territory Territory Parks and Wildlife Conservation Act 2000. 4. How judged by the Committee in relation to the EPBC Act criteria. The Committee judges the subspecies to be eligible for listing as vulnerable under the EPBC Act. The justification against the criteria is as follows: Criterion 1 – It has undergone, is suspected to have undergone or is likely to undergo in the immediate future a very severe, severe or substantial reduction in numbers. Hoya australis subsp. oramicola is endemic to the Northern Territory. The subspecies is restricted to coastal monsoon vine thicket communities on Bathurst and Melville Islands, where it is known from four localities (Kerrigan et al 2004). Very little data on abundance is available for this subspecies. Russell-Smith (1992) records this subspecies as common at Lubra Point on Bathurst Island and uncommon at Condor Point on Melville Island. -

Floral Glands in Asclepiads: Structure, Diversity and Evolution
Acta Botanica Brasilica - 31(3): 477-502. July-September 2017. doi: 10.1590/0102-33062016abb0432 Review Floral glands in asclepiads: structure, diversity and evolution Diego Demarco1 Received: December 7, 2016 Accepted: February 24, 2017 . ABSTRACT Species of Apocynaceae stand out among angiosperms in having very complex fl owers, especially those of asclepiads, which belong to the most derived subfamily (Asclepiadoideae). Th ese fl owers are known to represent the highest degree of fl oral synorganization of the eudicots, and are comparable only to orchids. Th is morphological complexity may also be understood by observing their glands. Asclepiads have several protective and nuptial secretory structures. Th eir highly specifi c and specialized pollination systems are associated with the great diversity of glands found in their fl owers. Th is review gathers data regarding all types of fl oral glands described for asclepiads and adds three new types (glandular trichome, secretory idioblast and obturator), for a total of 13 types of glands. Some of the species reported here may have dozens of glands of up to 11 types on a single fl ower, corresponding to the largest diversity of glands recorded to date for a single structure.

A Phylogenetic Approach Toward the Understanding of Disjunct Distributions of Plant Taxa in Western Ghats and Northeastern India
Rheedea Vol. 26(2) 99–114 2016 ISSN: 0971 - 2313 A phylogenetic approach toward the understanding of disjunct distributions of plant taxa in Western Ghats and northeastern India R. Puri1, P. Barman1,2 and R. Geeta1* 1Department of Botany, University of Delhi, Delhi – 110007, India. 2Division of Genomic Resources, National Bureau of Plant Genetic Resources, New Delhi – 110012, India. *E-mail: [email protected] Abstract There are many Indian plant taxa with disjunct distributions in northeastern India and Western Ghats, raising several systematic and biogeographic questions. Such questions are best addressed in a phylogenetic context as presented in this review of nine genera (Arisaema Mart., Begonia L., Ceropegia L., Hoya R. Br., Impatiens L., Indigofera L., Rubus L., Strobilanthes Blume and Vitis L.). These genera were chosen because they contain species that are endemic and occur in either northeastern India or Western Ghats, and at least one species is included in global phylogenetic analyses. This review reveals that even with limited sampling within India, the phylogenetic studies are consistent with present understanding of the Indian flora: that it contains Chinese, South East Asian and African influences, and that the collision of India with Asia played a crucial role in the dispersal of some taxa into India. Some of these dispersals occurred soon after the collision (e.g., Arisaema at 45 ma), while others were more recent (Begonia at 15 ma from SE Asia). Other dispersals occurred between India and Africa (e.g., Begonia at 13.75 ma and Indigofera 13 ma). We analyzed new sequences of ITS and atpB-rbcL regions from nine species of Impatiens, combined with existing data. -
Wax Plants Disentangled: a Phylogeny of Hoya (Marsdenieae, Apocynaceae) Inferred from Nuclear and Chloroplast DNA Sequences

We here infer major spe- cies groups in the genus based on combined sequences from the chloroplast atpB-rbcL spacer, the trnL region, and nuclear ribosomal DNA ITS region for 42 taxa of Hoya and close relatives. To assess levels of ITS polymorphism, ITS sequences for a third of the acces- sions were obtained by cloning. Most ITS clones grouped by species, indicating that speciation in Hoya usually predates ITS duplication. One ITS sequence of H. carnosa, however, grouped with a sequence of the morphologically similar H. pubicalyx, pointing to recent hybridization or the persistence of paralogous copies through a speciation event. The topology resulting from the combined chloroplast and nuclear data recovers some morphology-based sections, such as Acanthostemma and Eriostemma, as well as a well-supported Austra- lian/New Guinean clade. The combined data also suggest that morphological adaptations for ant-symbiosis evolved at least three times within Hoya. © 2006 Elsevier Inc. All rights reserved.

Manos ABSTRACT. The delimitation of the genus Hoya, with at least 200 species distributed from India and China to Australia, from its closest relatives in the Marsdenieae has long been problematic, precluding an understanding of the evolution and biogeography of the genus. Traditional circumscriptions of genera in the Hoya alliance have relied on features of the flower, but these overlap extensively between clades and may be evolutionarily labile. We obtained chloroplast DNA sequences to infer the phylogenetic relationships among a sample of 35 taxa of Hoya and 11 other genera in the tribe Marsdenieae, namely Absolmsia, Cionura, Dischidia, Dregea, Gongronema, Gunnessia, Madangia, Marsdenia, Micholitzia, Rhyssolobium,andTelosma. Trees were rooted with representatives of Asclepiadeae, Ceropegieae, Fockeeae, Periplocoideae, and Secamonoideae. Hoya and Dischidia form a monophyletic group, but the phylogenetic signal in the chloroplast data analyzed here was insufficient to statistically support the mutual monophyly of the two genera. A monophyletic Hoya, however, must include the monotypic Absolmsia, Madangia,andMicholitzia, a result congruent with their flower morphology. -
Pollinators of Hoya Pottsii: Are the Strongest the Most Effective?
Flora 274 (2021) 151734 Contents lists available at ScienceDirect Flora journal homepage: www.elsevier.com/locate/¯ora Pollinators of Hoya pottsii: Are the strongest the most effective? Sven Landrein a,1,*, Zi-Yu Zhou a,1, Shi-Jie Song a,b a Xishuangbanna Tropical Botanical Garden, Horticulture department, Menglun, Xishuangbanna, Yunnan, 666303 China b University of the Chinese Academy of Sciences, Beijing 100049 China ARTICLE INFO ABSTRACT Keywords: Hoya floral characters are highly elaborate and associated with a complex and specialised pollination mecha Pollination nism. The pollination of two Hoya species has been studied previously, but little is known about the specific Arolium nature and interactions between flowermorphology, pollinators, and their environment. Here we investigate the Erebinae pollination of Hoya pottsii, where pollinaria are transferred onto several insects’ legs and arolia including moths Guide rail in the Erebidae family, ants, and a praying mantis. Hypopyra vespertilio (Erebidae, Erebinae) was the most Hoya carnosa Hoya pottsii effective at both carrying and depositing the pollinaria, Colobopsis leonardii (Formicidae) was shown to suc Hypopyra vespertilio cessfully insert only one pollinium whereas Hymenopus coronatus (Hymenopodidae) could only attach the pol linaria between its two euplantulae. Several Hoya species were used to compare the effectiveness of pollinaria removal and insertion, pollinator size which was correlated to strength, floral scent, and morphology of the guide rail. The floral scent was dominated by Linalool, Methyl benzoate and Benzaldehyde which are known to attract moth, other species displayed similar scents but also showed many different compounds. The effectiveness of a medium-sized moth in pollinating H. pottsii could be explained by the morphology of the guide rail which comprises a landing platform for the arolium. -
Plant Biodiversity Science, Discovery, and Conservation: Case Studies from Australasia and the Pacific
Plant Biodiversity Science, Discovery, and Conservation: Case Studies from Australasia and the Pacific Craig Costion School of Earth and Environmental Sciences Department of Ecology and Evolutionary Biology University of Adelaide Adelaide, SA 5005 Thesis by publication submitted for the degree of Doctor of Philosophy in Ecology and Evolutionary Biology July 2011 ABSTRACT This thesis advances plant biodiversity knowledge in three separate bioregions, Micronesia, the Queensland Wet Tropics, and South Australia. A systematic treatment of the endemic flora of Micronesia is presented for the first time thus advancing alpha taxonomy for the Micronesia-Polynesia biodiversity hotspot region. The recognized species boundaries are used in combination with all known botanical collections as a basis for assessing the degree of threat for the endemic plants of the Palau archipelago located at the western most edge of Micronesia’s Caroline Islands. A preliminary assessment is conducted utilizing the IUCN red list Criteria followed by a new proposed alternative methodology that enables a degree of threat to be established utilizing existing data. Historical records and archaeological evidence are reviewed to establish the minimum extent of deforestation on the islands of Palau since the arrival of humans. This enabled a quantification of population declines of the majority of plants endemic to the archipelago. In the state of South Australia, the importance of establishing concepts of endemism is emphasized even further. A thorough scientific assessment is presented on the state’s proposed biological corridor reserve network. The report highlights the exclusion from the reserve system of one of the state’s most important hotspots of plant endemism that is highly threatened from habitat fragmentation and promotes the use of biodiversity indices to guide conservation priorities in setting up reserve networks. -

Fulton School of Veterinary and Life Sciences, Murdoch University, South Street, Murdoch WA 6150, AUSTRALIA. Centre for Biodiversity and Conservation Science, The University of Queensland, Brisbane Qld 4072, AUSTRALIA. Email: [email protected] Abstract: Thomas Reedy (1842-1929), gardener from 1854-1926 at Camden Park, the family estate of the Macarthurs in western Sydney was sent by Sir William Macarthur on the Chevert Expedition to New Guinea in 1875. He collected plants on islands off the Queensland coast; Cape Grenville; around the Somerset outpost on the tip of Cape York; on islands in the Torres Strait; and around two locations on the mainland of southern Papua New Guinea. Reedy sent or brought back 800-1000 living plants, in addition to an unknown number of seeds, and at least 157 dried specimens, the latter sent to Baron Ferdinand von Mueller in Melbourne. This study is focused on locating the dried plant specimens now held in herbaria and highlighting their significance. Reedy is something of an enigma with little ever written about him. His initial has been presented erroneously since 1875 and has gone through various morphs including J, P, M and T; searches for Reedy best use all these initials or just his family name.
