here seems to have been some doubt as to whether the specimens 
with more coriaceous reticulate leaflets are an ee stage of the 
above, but Welwitsch’s beautiful series at the British Museum 
Herbarium makes it clear that the membranous character of the 
leaflets of the above species is retained until full maturity.
