Genera
Dischidia
Dischidia is a genus of plants in the Milkweed family, Asclepiadaceae. It comprises about 80 known species which all grow as epiphytes and are native to tropical areas of China, India and most areas of Indo-China. Dischidia are closely aligned with the sister genus Hoya. Unlike Hoya, the genus Dischidia, is poorly known and has not been studied as closely. [more]
Diselma
Diselma archeri (syn. Fitzroya archeri (Hook.f.) Benth. & Hook.) is a species of plant of the family Cupressaceae and the sole species in the genus Diselma. It is found in Tasmania, on the western coast ranges and Lake St. Clair, at an altitude ranging from 910-1220 m. [more]
Fockea
Gymnema
Lianas. Cymes often racemelike, sessile or short pedunculate, often 2 at a node. Flowers small. Calyx with basal glands. Corolla campanulate; lobes ca. as long as tube, twisted to right or subvalvate, interior of tube with 5 longitudinal ridges, sometimes produced into fleshy appendages and/or with lines of hairs along each side. Corona lobes otherwise absent. Filaments connate into a tube; anthers erect, apical appendages membranous; pollinia 2 per pollinarium, oblong, erect. Stigma head hemispherical, obtusely conical or clavate and beaked, exceeding anthers. Follicles solitary or paired and widely divergent, ovoid to strongly beaked, often broad at base.[1] [more]
Hoya
Hoya is a genus of 200-230 species of tropical climbing plants in the family Apocynaceae (Dogbane), native to southern Asia (India east to southern China and southward), Australia, and Polynesia. Common names for this genus are waxplant, waxvine, waxflower or simply hoya. This genus was named by botanist Robert Brown, in honour of his friend, botanist Thomas Hoy. [more]
Marsdenia
Marsdenia is a genus of plant in family Apocynaceae. It contains the following species (but this list may be incomplete): [more]
Metaplexis
Lianas or scandent subshrubs. Leaves opposite, long petiolate. Inflorescences long pedunculate, racemelike with cymules laxly arranged along well-developed rachis. Calyx with 5 basal glands. Corolla subrotate; lobes longer than tube, twisted to left. Corona ringlike, inserted at base of gynostegium, rim 5-lobed; lobes hoodlike. Filaments connate into a short tube; anther appendages incurved; pollinia 2 per pollinarium, oblong or ovate-oblong, pendulous. Stigma head long beaked, 2-cleft or entire, exserted beyond anther appendages. Follicles fusiform or oblong, pericarp muricate, rugose, or smooth. Seeds ovate.[2] [more]
Sarcolobus
Telosma
Lianas. Leaves opposite, long petiolate. Cymes extra-axillary, pendulous, rachis laxly branched. Calyx with 5 glands at base. Corolla tube cylindric, with enlarged base, throat sometimes constricted; lobes patent, twisted to right. Corona lobes 5, adnate to base of staminal tube, margin and apex free, erect, oblong, obtuse, with ligulate inner lobes adnate to near apex, or corona lobes notched. Filaments connate into a tube; membranous anther appendages incurved; pollinia 2 per pollinarium, oblong, erect. Stigma head convex or conical. Follicles thick, acuminate, smooth. Seeds comose.[3] [more]
At least 15 species and subspecies belong to the Genus Telosma.
