The Flora of Angola: Collectors, Richness and Endemism
Angola is botanically rich and floristically diverse, but is still very unevenly explored with very few collections from the eastern half of the country. We present an overview of historical and current botanical activity in Angola, and point to some areas of future research. Approximately 6850 species are native to...Goyder, David ; Gonçalves, Francisco

Optimization of cryopreservation protocols for zygotic embryos of Citrus reticulata
Citrus seeds are known to have short life spans in conventional seed banks. Seed of most Citrus species show a typical intermediate storage behaviour where they survive desiccation to c. 7-10%. However, longevity is compromised at this low moisture content at sub-zero temperatures. Cryopreservation of zygotic embryos is an option...Nadarajan, J ; Akter, A

Hyper-epigyny is the ultimate constraint on orchid floral morphology and an ideal model for testing the Extended Synthesis
The developmental morphology and genetics of the orchid flower is described in order to explore the evolutionary ‘no man’s land’ that separates the Extended Synthesis from the Modern Synthesis. The gynostemium, ubiquitous among orchids and developed through congenital fusion (and dorsal suppression) of fertile reproductive organs, is an unbreakable evolutionary...Bateman, Richard ; Rudall, Paula
