PHANEROGAMS— PROFESSOR BAYLEY BALFOUR. 219 



Socotra. A shrub or small tree of the Haghier hills, and also on the lime- 

 stone plateaux south-west from Galonsir at an elevation of over 1500 feet. 

 B.C.S. nn. 300, 529. Schweinf. n. 605. 



Distrib. Endemic. 



Like so many other plants this species exhibits a dwarfed intricately- 

 branched small-leaved form (n. 529) on dry limestone regions, and a more 

 twiggy erect habit with larger leaves in regions with a more favourable soil. 

 Its flowers are very pretty, and it may be at once diagnosed from the other 

 species by its rounded leaves, and the cymose axillary inflorescence.

A third pretty-flowered species of this genus, readily recognised by its per- 

 sistently oblong leaves, which are longer than in the other species, and by its 

 very conspicuous black twigs.

A large genus of polymorphous species widely dispersed over the warmer 

 regions of the globe. One of the Socotran species is endemic, the other is a 

 remarkable south-west Asiatic and north-east African species.

A very remarkable species exhibiting a curious dimorphism in the 

 fruit. This feature has been noticed in the plant, as its names indicate, from 

 the date of its discovery, but it is one to which sufficient prominence has not
