South Africa Cape Wildflowers, Birding & Big Game II 21St August to 3Rd September 2022 (14 Days)
South Africa Cape Wildflowers, Birding & Big Game II 21st August to 3rd September 2022 (14 days) Cape Mountain Zebras & wildflowers in West Coast NP by Adam Riley This comprehensive tour covers the most exciting regions of the Cape in our quest to experience both breathtaking displays of wildflowers and to track down some of the country’s endemic birds. We begin in the vibrant city of Cape Town, where Table Mountain provides a spectacular backdrop to the immensely diverse fynbos that cloaks the cities periphery. This fynbos constitutes the Cape Floral Kingdom – the smallest and richest of the world’s 6 floral kingdoms. It is also the only floral kingdom to be confined to the boundaries of a single country. Thereafter we venture to the West Coast and Namaqualand, which boast an outrageous and world famous floral display in years of good rains, before travelling through the heart of the country’s semi-desert region, focusing on the special bird’s endemic to this ancient landscape. We conclude the journey heading out of wildflower country to Augrabies Falls, an area offering unparalleled raptor viewing and a wide range of dry region birds. We invite you on this celebration of some of the finest wildflower and endemic birding that the African continent has to offer!

Family Classification
1.0 GENERAL INTRODUCTION 1.1 Henckelia sect. Loxocarpus Loxocarpus R.Br., a taxon characterised by flowers with two stamens and plagiocarpic (held at an angle of 90–135° with pedicel) capsular fruit that splits dorsally has been treated as a section within Henckelia Spreng. (Weber & Burtt, 1998 [1997]). Loxocarpus as a genus was established based on L. incanus (Brown, 1839). It is principally recognised by its conical, short capsule with a broader base often with a hump-like swelling at the upper side (Banka & Kiew, 2009). It was reduced to sectional level within the genus Didymocarpus (Bentham, 1876; Clarke, 1883; Ridley, 1896) but again raised to generic level several times by different authors (Ridley, 1905; Burtt, 1958). In 1998, Weber & Burtt (1998 ['1997']) re-modelled Didymocarpus. Didymocarpus s.s. was redefined to a natural group, while most of the rest Malesian Didymocarpus s.l. and a few others morphologically close genera including Loxocarpus were transferred to Henckelia within which it was recognised as a section within. See Section 4.1 for its full taxonomic history. Molecular data now suggests that Henckelia sect. Loxocarpus is nested within ‗Twisted-fruited Asian and Malesian genera‘ group and distinct from other didymocarpoid genera (Möller et al. 2009; 2011). 1.2 State of knowledge and problem statements Henckelia sect. Loxocarpus includes 10 species in Peninsular Malaysia (with one species extending into Peninsular Thailand), 12 in Borneo, two in Sumatra and one in Lingga (Banka & Kiew, 2009). The genus Loxocarpus has never been monographed. Peninsular Malaysian taxa are well studied (Ridley, 1923; Banka, 1996; Banka & Kiew, 2009) but the Bornean and Sumatran taxa are poorly known. -
Do Sympatric Heliconias Attract the Same Species of Hummingbird? Observations on the Pollination Ecology of Heliconia Beckneri and H
Do Sympatric Heliconias Attract the Same Species of Hummingbird? Observations on the Pollination Ecology of Heliconia beckneri and H. tortuosa at Cloudbridge Nature Reserve Joseph Taylor University of Glasgow The Hummingbird-Heliconia Project The hummingbird family (Trochilidae), endemic to the Neotropics, is remarkable not only for its beauty but also because of its ability to hover over a flower while feeding, its wing movements a blur. These lively birds require frequent, nutritious feeding to sustain their expenditure of energy, and some plants have evolved to attract and feed them in exchange for pollination services. Prominent among such plants are most species in the genus Heliconia (Heliconiaceae), which are medium to large clone-forming herbs with banana-like leaves (Stiles, 1975). The hummingbird-Heliconia interdependence is a good example of co- evolution, and this study is concerned with one aspect of this relationship. Since several species of hummingbird and Heliconia exist at Cloudbridge, a middle-elevation nature reserve in Costa Rica, we wondered whether particular species of Heliconia had evolved an attraction for particular hummingbird species, which might reduce the chances of hybridisation and pollen loss; or whether the plants compete for a variety of hummingbirds. At Cloudbridge, on the Pacific slope of southern Costa Rica’s Talamanca mountain range, Heliconia beckneri , an endangered species (website 1) restricted to this area and thought to be of hybrid origin (Daniels and Stiles, 1979; website 2), and H. tortuosa occur together. Stiles (1979) names the Green Hermit ( Phaethornis guy ) as the primary pollinator of both species and the Violet Sabrewing ( Campylopterus hemileucurus ) as the secondary pollinator of H. -

This thesis has not in whole or in part been previously presented for any degree Subhani Wathsala Ranasinghe 24th January 2017. i Abstract The plant family Gesneriaceae is represented in Sri Lanka by six genera: Aeschynanthus, Epithema, Championia, Henckelia, Rhynchoglossum and Rhynchotechum, with 13 species (plus one subspecies/variety) of which ten are endemic including the monotypic genus Championia, according to the last revision in 1981. They are exclusively distributed in undisturbed habitats, and some have high ornamental value. The species are morphologically diverse, but face a problem of taxonomic delineation, which is further complicated by the presence of putative hybrids. -

1 CHAPTER 6134 DEPARTMENT OF NATURAL RESOURCES ENDANGERED, THREATENED, SPECIAL CONCERN SPECIES 6134.0100 STATUTORY AUTHORITY. 6134.0150 PURPOSE AND SCOPE. 6134.0170 SPECIES NAMES. 6134.0200 ANIMAL SPECIES. 6134.0300 VASCULAR PLANTS. 6134.0400 LICHENS; MOSSES; LIVERWORTS; FUNGI. 6134.0100 STATUTORY AUTHORITY. Pursuant to Minnesota Statutes, section 84.0895, the species of wild animals and plants listed in parts 6134.0200 to 6134.0400 are designated as endangered, threatened, or of special concern, as indicated in those parts. Statutory Authority: MS s 84.0895 History: 8 SR 1921; L 1986 c 386 art 4 s 9 Published Electronically: June 11, 2008 6134.0150 PURPOSE AND SCOPE. Minnesota Statutes, section 84.0895, subdivision 3, requires the commissioner of natural resources to adopt rules designating species meeting the statutory definitions of endangered, threatened, or species of special concern. Minnesota Statutes, section 84.0895, subdivision 5, authorizes the commissioner to adopt rules that regulate treatment of species designated as endangered or threatened. Thus, two different sets of rules have been adopted: parts 6134.0100 to 6134.0400 designate species in the three statutory categories; and parts 6212.1800 to 6212.2300 create regulations for species designated as endangered or threatened. Species designated as species of special concern are not protected by Minnesota Statutes, section 84.0895 or rules adopted under that section. Parts 6212.1800 to 6212.2300 and Minnesota Statutes, section 84.0895, impose a variety of restrictions, a permit program, and several exemptions pertaining to species designated as endangered or threatened. Among these are that acts otherwise prohibited may be allowed by permit issued by the commissioner; plants on certain agricultural lands and plants destroyed in consequence of certain agricultural practices are exempt; and the accidental, unknowing destruction of designated plants is exempt. -
