PHANEROGAMS — PROFESSOR BAYLEY BALFOUR. 9 



unguiculata calyce duplolongiora, postica duo v. tria purpurea limbis subdeltoideis acutis 

 Stamina 6 basi libera. Stylus brevis. Siliqua late oblongo-linearis \-1 poll, longa \-\ 

 poll, lata scabra venosa recta adscendens subsessilis. Semina pubescentia. 



Socotra. Not uncommon. B.C.S. nn. 76, 404. Schweinf. nn. 659, 

 710. 



Distrib. Endemic. 



This plant I at first considered to be a form of CI. arabica, Linn., a wide- 

 spread North African and Arabian species. In habit the species resemble one 

 another closely, and the likeness is especially marked in the Arabian forms of 

 CI. arabica. But the less scabrid character of the Socotran plant, its broader 

 leaves, form of petals, straight ascending pods, and lastly, its smaller hairy not 

 cottony seeds, sufficiently separate it. Schweinfurth sends two specimens of the 

 plant, one of which n. 659 is almost as scabrid as CI. arabica. 



Like all Cleomes it is a somewhat variable plant according as it occurs 

 on dry plains or in sheltered favourable situations. Sometimes in the latter 

 habitats it is perfectly glabrous, and then the leaves are much larger than 

 is normally the case.

Distrib. Southern India and Tropical Africa. 



The Socotran specimens resemble more the African than the Indian plants, 

 the latter being, as Hooker and Thomson (loc. cit.) state, of smaller dimensions, 

 though identical with that of Africa. The seeds are " globose reniform minutely 

 rugulose pitted " (Oliv. loc. cit) not " smooth " (Hook. fil. and Thorns, loc. cit.).

Distrib. Arabia to north-west India, and in Nile Land. 



A very variable plant, both in size of leaf and in amount of glandular 

 clothing. In Socotra it varies in this latter respect from densely glandulose to 

 nearly glabrous.
