Distrib. Endemic. 



A very distinct species. It grows as a dwarf, hard, woody under-shrub on 

 the high limestone plains, and like other Socotran species is a disagreeable 

 scrub plant, on account of its easily detached forked hairs. Its most marked 

 feature is the convolution of the petals to form a narrow tube in their lower 

 part, whilst above they are spreading.

Socotra. Not abundant near Adho Dimellus. B.C.S. n. 488. Schweinf. 

 nn. 535, 535 b, 535 c 1 



Dtstrib. Endemic. 



A species having a not remote affinity with the African ff. gossypinus, 

 Thunb. (Flor. Cap. 549; Mast, in Oliv. Flor. Trop. Afr. i. 205), which is, however, 

 distinguished by its subcordate thick leaves, generally denser pubescence, and 

 absence of brown setse, while the epicalyx consists of shorter and stouter 

 bracteoles. 



Schweinfurth, under n. 535, sends specimens from several localities. Some of 

 these are undoubtedly of H. Scotti, but some I take to be of a different species, 

 and I believe may be referred to this one. I have not, however, in the 

 description above incorporated any character derived from his specimens, as 

 our specimens like his are few in number, and it is better to wait for further 

 investigation of the flora before deciding the limits of the species. Schwein- 

 furth considers all his specimens as being of one species.
