Socotra. Very common. B.C.S. 116. Scliweinf. nn. 238, 382 in lit. . 



Distrib. Endemic. 



One of the commonest plants on the island, occurring on all the plains, and 

 one would hardly expect that it should be an endemic species ; but I am 

 unable to match it. Its nearest ally is C. chondrilloides, Boiss., a plant of south 

 Persia ; but the glabrous subaphyllous condition of this plant, its less scoparioid 

 habit, the inflorescence and hirsute ovary are sufficiently distinctive. Indeed, 

 from all the species in Boissier's section Inermes, our plant is readily 

 diagnosed by its glabrous ovary. 



2. 0. sarmentosus, Balf. fil. in Proc. Eoy. Soc. Edin. xii. (1882), 83. 



Subpulvinatus inermis lignosus perennis argenteo-sericeus ramis brevibus basi congestis cum 

 ramulis paucis virgatis sarmentosis ; foliis basalibus rosulatis oblanceolatis, superioribus 

 ovato-acutis v lanceolatis ; floribus pedicellatis breves racemos simplices formantibus ; 

 ovario glabro ; seminibus puberulis. 



Suffrutex lignosus bumilis prostratus subpulvinatus argenteo-sericeus a collo ramosus, ramorum 

 baseis brevitms congestis perennibus depressis, ramulis superioribus in virgas annuas 

 sarmentosas apice adscendentes elongatis. Folia ad apices ramorum inferiorum rosulata 

 oblanceolata v. anguste obovata obtusa v. late acuta 1 poll, longa | poll, lata in petiolum 

 gradatim attenuata, in ramis pulvinatis folia omnino minora, superiora in ramis elongatis 

 remota subsessilia oblongo-acuta v. lanceolata longitudine latitudineque variantia.

Socotra. On the limestone plateau overlooking Galonsir valley on the 

 west, at an elevation over 1500 feet. B.C.S. nn, 131?, 302. 



Distrib. Endemic. 



A pretty white-flowered species, a very characteristic plant of the dry lime- 

 stone plains. We only found it at one locality. Its position in the genus is in
