The orthography adopted for the local names has met with 
some criticism from South African botanists. It has been

Two niu will be for ever memorable in the history of South 
African Botany 
- More than thirty years have rolled away since Professor Harvey 
bore eloquent testimony to the indefatigable services of Peter 
his enthusiasm for the beautiful Flora amidst which he has spent 
the best years of his life, nor his energy in investigating it. 
Without his self-sacrificing aid the present — would 
have been miserably incomplete. By a correspondence which 
has never intermitted, he has done all in his power to keep Kew

To Harry Bolus, Esq., F.L.S., the gratitude of Kew is no less

admirable researches into the difficult problem of the geographical 
distribution of South African plants, and his patience and accurate 
investigation of the Orchidee and other groups, will, it may be

hundreds of specimens—a large proportion of which were new to 
seience, and many of great interest and rarity 
At the risk of seeming to make an invidious choice amongst a

rarer and more remarkable of South African plants. e paid

interesting introductions to European demie the remarkable 
tree-aloe (Aloe dichotoma) deserves especial mention, And it
