Socotra. On the plains. Not common. B.C. S. n. 114. Schweinf. n. 258. 



Distrib. Endemic. 



Anotlier Convolvuloid species of this genus, closely resembling such 

 Arabian forms as Convolvulus compactus Boiss. (Diagn. ser. i. 4. 40, and Flor. 

 Orient, iv. 98) and its allies. But as in the case of the foregoing species the 

 capitate stigmas technically exclude it from Convolvulus, and its ovary equally 

 separates it from Evolvulus. It is quite a distinct species in this genus, and 

 a very typical desert form.

Nom. Vern. Sahdek (B.C.S.). 



Socotra. Common on the plains. B.C.S. nn. 73, 273. Schweinf. n. 249. 



Distrib. Endemic. 



One of the commonest plants on Galonsir plain and on other plains of the 

 island, its dwarf, half shrubby dendriform habit giving a peculiar feature to 

 the plains. There can be little doubt a plant so abundant on the island occurs 

 on the adjacent continents, but as yet we only know it as endemic in Socotra. 



Is it rightly referred to this genus? Its habit is thoroughly Breweriod,
