The genus Ursinia, Gaertn., with which is now incor- 

 porated Sphenogyne, E. Br., includes between sixty and 

 seventy species, all of them African and almost all con- 

 fined to extra-tropical South Africa. Many of the forms 

 are closely allied to each other and difficult to distin- 

 guish unless examined in a living state. A few of them 

 are already grown in Europe as half-hardy annuals, and 

 U. cakilefolia, now figured, introduced to Kew in 1914 

 by means of seed received from Professor Pearson 

 Director of the National Botanic Garden, Kirstenbosch 

 Cape Town, promises to be a useful addition to the 

 D i Um J?. e , r ; Thls s P ecies was first collected by Drege, on 

 the Giftberg, in South- West Africa, and appears to have 

 been met with again by Mr. N. S. Pillans, from whose 

 garden came the seeds whence the Kirstenbosch plants 



September, 1916.
