  • Rapid Creek Species Lists
    NATIVE VEGETATION SPECIES The Rapid Creek Landcare Group compiled these lists to inform revegetation work. The habitat based lists include a range of species that are appropriate to be planted in the catchment. The following references were used: • Rapid Creek Management Plan (1994) Prepared for Darwin City Council and Greening Australia by Clouston • Terrestrial Flora and Fauna Surveys of Darwin International Airport (2009) Prepared for NT Airports by EcOz Environmental Services • Rapid Creek Vegetation Survey Prepared by Clark and Brocklehurst in the early 1990’s • Expert botanical advice A focus is placed on tree and shrub species likely to be used in revegetation. It is recommended site specific expert advice be sought before finalising species lists for particular projects.

Trees or erect shrubs, dioecious; indumentum of simple hairs. Leaves alternate, eglandular; stipules small; petiole usually short; leaf blade simple, margin entire, venation pinnate. Inflorescences axillary, sometimes apparently terminal, or cauline, spikes or ra- cemes, sometimes much branched. Male flowers: calyx 3–5(–8)-lobed, cup-shaped, lobes imbricate; petals absent; disk extrastaminal, annular or cushion-shaped (enclosing bases of stamens and pistillode), or consisting of free lobes; stamens (1–)3–5(– 7), inserted inside/within disk or sinus of disk lobes, incurved in bud, afterward straight; filaments longer than sepals; anthers 2- locular, connectives U-shaped; thecae separate from each other, resembling swollen ends of U, raised at anthesis, dehiscing longitudinally; pistillode usually present. Female flowers: sepals as in male; disk annular surrounding ovary, entire; ovary longer than sepals, usually 1-locular; ovules 2 per locule, pendent; styles 2–4, short, terminal to lateral, apex usually bifid. Fruit a drupe, ovoid, ellipsoid, or lens-shaped, with many areoles when dry, crowned with persistent styles, usually 1-seeded. Seeds small, endosperm fleshy, cotyledon flattened and broad. x = 13. About 100 species: mainly the tropics and subtropics of Asia but also in Africa (8 species), the Pacific islands (5–8 species), and Australia (5–7 species); 11 species (two endemic) in China. Material of species no. 11, Antidesma hontaushanense, described from Taiwan (Lan Yu), has not been seen and the available description is too poor to include this taxon within the key to species.

For the interests of the Forestry Bureau the names of the va- rious tree species only are of importance, but in compiling this list all plant names avaliable have been included in order to make the present Avork more generally useful to those Americans resident in the Archipelago who are interested in the vegetation about them.

A total of 14 sample plots was established, each sample plot of 500m2 (25m x 20m) and randomly distributed through tropical evergreen broad-leaved humid low mountain forest and tropical broad- leaved dry forest state. Two main contents were carried out: (i) Determine taxa diversity, life-forms, parts used, disease groups, threatened medicinal plants, (ii) identify diverse indicators of medicinal plants. The results showed that a total of 55 medicinal plant species, 50 genera, 36 families of 3 phyla was found in Nui Chua National Park. Among them, 9 threatened species was listed in the Vietnam Red Data Book (2007), and the IUCN Red List (2019). The life-forms of medicinal plants were recorded as woody plant, herbaceous, shrubs, epiphyte, and vines.

Sporidesmium liquidambaris sp. nov. on Liquidambar formosana, S. antidesmatis sp. nov. on Antidesma ghaesembilla, and S. machili sp. nov. on Machilus chinensis, are described, illustrated, and compared with closely related taxa. Sporidesmium takashii is recorded as new for the Chinese mycota. Key words — conidial fungi, taxonomy Introduction The genus Sporidesmium (anamorphic Pleosporales) was established by Link (1809) with S. atrum Link as type species. Ellis (1958, 1971) defined the genus as having integrated, terminal, monoblastic, determinate or percurrent conidiogenous cells on distinctive, unbranched conidiophores, and acrogenous, solitary, transversely septate or distoseptate conidia. Under this generic concept, about 250 species are included in this genus. However, Sutton & Hodges (1979) and Hughes (1979) felt that Sporidesmium is heterogeneous, an opinion confirmed by Shenoy et al. (2006) who showed the polyphyletic nature of Sporidesmium and its allies. Kirk (1982) proposed the new genus Sporidesmiella
