Vegetation, Floristic Composition and Species Diversity in a Tropical Mountain Nature Reserve in Southern Yunnan, SW China, with Implications for Conservation
Mongabay.com Open Access Journal - Tropical Conservation Science Vol.8 (2): 528-546, 2015 Research Article Vegetation, floristic composition and species diversity in a tropical mountain nature reserve in southern Yunnan, SW China, with implications for conservation Hua Zhu*, Chai Yong, Shisun Zhou, Hong Wang and Lichun Yan Center for Integrative Conservation, Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences, Xue-Fu Road 88, Kunming, Yunnan 650223, P. R. China Tel.: 0086-871-65171169; Fax: 0086-871-65160916 *Corresponding author: H. Zhu, e-mail [email protected]; Fax no.: 86-871-5160916 Abstract Complete floristic and vegetation surveys were done in a newly established nature reserve on a tropical mountain in southern Yunnan. Three vegetation types in three altitudinal zones were recognized: a tropical seasonal rain forest below 1,100 m; a lower montane evergreen broad- leaved forest at 1,100-1,600 m; and a montane rain forest above 1,600 m. A total of 1,657 species of seed plants in 758 genera and 146 families were recorded from the nature reserve. Tropical families (61%) and genera (81%) comprise the majority of the flora, and tropical Asian genera make up the highest percentage, showing the close affinity of the flora with the tropical Asian (Indo-Malaysia) flora, despite the high latitude (22N). Floristic changes with altitude are conspicuous. The transition from lowland tropical seasonal rain forest dominated by mixed tropical families to lower montane forest dominated by Fagaceae and Lauraceae occurs at 1,100-1,150 m. Although the middle montane forests above 1,600 m have ‘oak-laurel’ assemblage characteristics, the temperate families Magnoliaceae and Cornaceae become dominant.

Bardi Plants an Annotated List of Plants and Their Use
H.,c H'cst. /lust JIus lH8f), 12 (:J): :317-:359 BanE Plants: An Annotated List of Plants and Their Use by the Bardi Aborigines of Dampierland, in North-western Australia \!o\a Smith and .\rpad C. Kalotast Abstract This paper presents a descriptive list of the plants identified and used by the BarcE .\borigines of the Dampierland Peninsula, north~\q:stern Australia. It is not exhaust~ ive. The information is presented in two wavs. First is an alphabetical list of Bardi names including genera and species, use, collection number and references. Second is a list arranged alphabetically according to botanical genera and species, and including family and Bardi name. Previous ethnographic research in the region, vegetation communities and aspects of seasonality (I) and taxonomy arc des~ cribed in the Introduction. Introduction At the time of European colonisation of the south~west Kimberley in the mid nineteenth century, the Bardi Aborigines occupied the northern tip of the Dam pierland Peninsula. To their east lived the island-dwelling Djawi and to the south, the ~yulnyul. Traditionally, Bardi land ownership was based on identification with a particular named huru, translated as home, earth, ground or country. Forty-six bum have been identified (Robinson 1979: 189), and individually they were owned by members of a family tracing their ownership patrilineally, and known by the bum name. Collectively, the buru fall into four regions with names which are roughly equivalent to directions: South: Olonggong; North-west: Culargon; ~orth: Adiol and East: Baniol (Figure 1). These four directional terms bear a superficial resemblance to mainland subsection kinship patterns, in that people sometimes refer to themselves according to the direction in which their land lies, and indeed 'there are.

The beachside community of Machan’s Beach adjoins Redden Creek and the Cairns CBD is just a few kilometres south. We have inspected the Island several times over the years and it is always of interest to note any changes. The area is low lying and dynamic, being part of the large Barron delta system with its potential of flood generated change. Indeed, as we walked along the river bank there was evidence of erosion from the strong currents resulting from heavy cyclonic rain during the previous few days. March is A.G.M. month and we had a larger than usual attendance of members vying to be elected to the Executive! Long term member Liz invited us to meet at her place and we enjoyed the idyllic ambience of a beach-side house built in the way that one can only dream of. Open areas, cool breezes, sweeping ocean views and extensive gardens built around existing trees augmented by appropriate plants native to the area.

Other illustrations are based on photocopies and recently coloured scans of actual plants. Photographs of flowers chiefly by Andi Cairns, John Elliott, Chris Gardiner, Don Kinsey and Andrea Lim. The map was prepared by Adella Edwards, Cartography, James Cook University, modified from Sandercoe (1990) with permission of the Director, Queensland Herbarium. Andi Cairns provided valuable assistance with the layout and with suggestions on the manuscript. To all those who have suggested changes, who have provided lists of plants, particularly the staff of the Queensland Herbarium, my grateful thanks.

Jackes Magnetic Island (190 08 S, 1480 50 E), offshore from the north Queensland city of Townsville, was first named by Captain James Cook in 1770. He called it “Magnetical Point, land which has the appearance of an island”, because his compass moved erratically as he passed it. This large island, about 5,000 ha in area, rises to 493 m at Mt Cook, the highest point.

China, 3 Jinggangshan Administration of Jiangxi Province, Jinggangshan, Jiangxi, P. R. China Abstract The Mount Jinggangshan region is located between Jiangxi and Hunan provinces in southeastern China in the central section of the Luoxiao Mountains. A detailed investigation of Mount Jinggangshan region shows that the seed plant flora comprises 2,958 species in 1,003 genera and 210 families (Engler’s system adjusted according to Zhengyi Wu’s concept). Among them, 23 species of gymnospermae belong to 17 genera and 9 families, and 2,935 species of angiosperms are in 986 genera and 201 families. Moreover, they can also be sorted into woody plants (350 genera and 1,295 species) and herbaceous plants (653 genera and 1,663 species). The dominant families are mainly Fagaceae, Lauraceae, Theaceae, Hamamelidaceae, Magnoliaceae, Ericaceae, Styracaceae, Aquifoliaceae, Elaeocarpaceae, Aceraceae, Rosaceae, Corylaceae, Daphniphyllaceae, Symplocaceae, Euphorbiaceae, Pinaceae, Taxodiaceae, Cupressaceae and Taxaceae.

Flora of Singapore Precursors, 14. Notes on Apocynaceae
Gardens’ Bulletin Singapore 71 (1): 69–80. 2019 69 doi: 10.26492/gbs71(1).2019-04 Flora of Singapore precursors, 14. Notes on Apocynaceae M. Rodda & D.J. Middleton Singapore Botanic Gardens, National Parks Board, 1 Cluny Road, 259569 Singapore [email protected] ABSTRACT. Lectotypes are designated for 28 names of Apocynaceae, seven of which are second-step lectotypifications. Two names are neotypified, Leptostemma hirsutum Blume is designated as the type of the genus Leptostemma Blume, and a new combination in Secamone R.Br. is coined for Genianthus maingayi Hook.f. Keywords. Genianthus, lectotype, neotype, Secamone Introduction During the preparation of the account of Apocynaceae for the Flora of Singapore, types of all taxa occurring in Singapore and their synonyms were verified. For those taxa in the informal groups known as the rauvolfioid and apocynoid Apocynaceae (corresponding to the family before the Asclepiadaceae was included), most of the typifications were already done in previous works (see Middleton, 2007, 2011). Some of these require refinement. In addition, numerous asclepiad Apocynaceae names require typification or corrections to earlier typifications. The second part of the paper addresses the generic placement of Genianthus maingayi Hook.f. The status of the Asian genera Genianthus Hook.f. and Toxocarpus Wight & Arn. and their relationships with the widespread Secamone R.Br. (Old World tropics and subtropics) are still to be clarified. However, Klackenberg (2001, 2004) considered the three genera congeneric. His argument was based on the observation that even though the three genera can be separated morphologically in Asia, Secamone in Madagascar is extremely variable and Madagascan species include characters such as the dorsiventrally compressed corona lobes and the long style heads, also observed in Genianthus and Toxocarpus.
