A new Ypsilopus (Orchidaceae, Angraecinae) from Zimbabwe and notes on the parallel evolution of extreme column exsertion in African angraecoids.
– A preliminary review of hawkmoth-pollinated angraecoids from Africa unveiled a remarkable case of parallel evolution of extreme column exsertion between the two species formerly classified in in the defunct genus . These belong to one clade of , including and , and Ypsilopus sect. Barombiella, including and . The... -

New combinations in Aeridinae (Orchidaceae).
New combinations are made in the genera Arachnis, Brachypeza, Dimorphorchis, Grosourdya, Phalaenopsis, Renanthera, Robiquetia, Taeniophyllum, Thrixspermum, Trachoma and Trichoglottis. Two new subgenera are established in Phalaenopsis (subgen. Ornithochilus and Hygrochilus). These changes are proposed to begin aligning the genera recognized in subtribe Aeridinae with results of recent DNA analyses (published...Kocyan, Alexander ; Schuiteman, André

Comparative Seed Cryopreservation of Indonesian and New Zealand Epiphytic And Terrestrial Orchids.
The atypical seed storage behaviour reported in several orchid species justifies cryopreservation as a complementary conservation strategy to conventional seed banking. This study aimed to assess the seed cryopreservation potential of five orchid species; tropical epiphytic, Indonesian species (Dendrobium strebloceras, D. lineale), one temperate New Zealand species (D. cunninghamii) and... -

Seed Micromorphology of Eleven Species of Pleione (Orchidaceae).
The micromorphological characteristics of the seeds of 11 species of Pleione have been studied, both qualitatively and quantitatively, to establish whether they are useful for systematic studies of the genus. The quantitative characteristics include seed length (0.237–0.626 μm), seed width (0.053–0.133 μm), seed length/width ratio (2.631–7.279), seed ridge thickness (1.4...Wang, Zhongxuan ; Zhang, Hao ; Qin, Si ; You, Le ; Zhai, Junwen …
