Heterostemma Wight & Arn. (Asclepiadaceae) and a new species from India. Heterostemma vasudemni Swarupanandan & Mangaly, a new species belonging to Asclepiadaceae is described and illustrated. The discoid-urceoloate corolla and the staminal coronal scales with a ventral appendage show this species to be intermediate between the two genera Heterostemma and Oianthus. Basically, the concepts of the two genera differ only in a pair of characters which, in the light of the new species seem not to be… 
Heterostemma ficoides (Apocynaceae: Asclepiadoideae), a new species with fig-like flowers from Northern Thailand
Heterostemma ficoides resembles H. vasudevanii in having a fleshy globose flower and the presence of the inner corona appendages, but clearly differs in leaf shape, leaf venation, presence of dense hairs on the outer and inner surfaces of the corolla, and apex of the staminal corona lobes.
The subfamilial and tribal classification of the family Asclepiadaceae
A modified classification of the family Asclepiadaceae into three tribes and the position of attachment of the caudicles to the pollinia is suggested as a criterion for defining the erect and pendulous stature of the pollinaria.
On the systematic position of some Asian enigmatic genera of Asclepiadoideae (Apocynaceae)
The study confirms the generally accepted tribal and subtribal structure of the subfamily Asclepiadoideae and confirms the need for a placement of Eustegia as an independent tribe.
Heterostemma trilobatum sp. nov. (Apocynaceae: Asclepiadoideae) from Thailand
A new species, Heterostemma trilobatum, discovered in northern, northeastern and southeastern Thailand has been discovered and is here described, illustrated and meticulously compared with a morphologically similarspecies, H. xuansonense.
Subtribal division of Ceropegieae (Apocynaceae-Asclepiadoideae)
Monophyly and sister group relationship of Ceropegieae and Marsdenieae, the two Asclepiadoideae tribes possessing erect pollinia, are confirmed by molecular investigation of non-coding cpDNA markers
Heterostemma cucphuongense (Apocynaceae, Asclepiadoideae), a new species from Vietnam
Heterostemma cucphuongense differs from H. succosum by the morphology of the rachis of the inflorescence, the margins of the corolla lobes and the colour of the adaxial surface of the Corolla.
Towards a Monophyletic Hoya (Marsdenieae, Apocynaceae): Inferences from the Chloroplast trnL Region and the rbcL-atpB Spacer
Chloroplast DNA sequences were obtained to infer the phylogenetic relationships among a sample of 35 taxa of Hoya and 11 other genera in the tribe Marsdenieae, and identified several well-supported groups within Hoya.
Heterostemma brownii (Apocynaceae), a new record for Laos and Thailand
Heterostemma brownii is reported as a new record for the floras of Laos and Thailand. A lectotype is also designated for the name Heterostemma brownii. A description based on Thai and Lao
Heterostemma succosum (Apocynaceae), a new record for Laos
Heterostemma succosum is reported as a new record for Laos. A description and an illustration are provided.


A dictionary of the flowering plants and ferns
The entries attempt to cover all published generic names from 1753 onwards and published family names from1789, together with a number of supra- and infra-familial taxa where these have not been based on family or generic names.
