6 BOTANY OF SOCOTRA. 



Socotra. On the plains about Galonsir, not common. B.C.S. n. 205. 



Distrib. Endemic. 



Of this plant I have only one specimen, and that not a good one. It bears, 

 however, a flower and two pods. The characters derived from these and from 

 the leaves prevent the plant being incorporated in any described species. 

 The association of a linear pod with broad leaves is not commonly met with 

 m the genus. 



3. Farsetia, Sp. 



Socotra. B.C.S. n. 586. 



A few fragments of inflorescence bearing flowers and one or two fruits of a 

 species of this genus are in our collection. There are no leaves with the 

 inflorescences, and as they turned up in a small packet containing delicate 

 flowers and fruits of plants, complete specimens of which are in our collection, 

 I suppose they have been dried in the belief that they belonged to one of the 

 two species already mentioned. They are marked as collected near Galonsir, 

 but I have no recollection of gathering them, and they do not belong to either 

 species. The flowers are small, about the size of those of F. linearis, Dene., but 

 the style is much longer (f in.) than in that species, more tapered and more 

 deeply bifid, and with the lobes connivent. The pod is about an inch long, and 

 the valves are finely reticulate-venulose and hardly strigose. I have not been 

 able to refer them to any described species. 



3. SISYMBRIUM. 



Sisymbrium, Linn. Gen. n. 813 ; Benth. et Hook. Gen. PI. i. 77. 



A large genus of mainly European and Eastern Asiatic distribution, but 

 represented in most temperate regions. Very few species occur in the southern 

 hemisphere. 



S. erysimoides, Desf. Fl. Atl. ii. 84. 1. 158 ; DC. Syst. Veg. ii. 482 ; Boiss. 

 Flor. Orient, i. 217 ; Oliv. Flor. Trop. Afr. i. 64 ; Fourn. Monogr. Crucif. 92. 



Socotra. An occasional weed. B.C.S. n. 700. Schweinf. n. 508. 



Distrib. A plant of the Mediterranean region, and found also in Canary 

 Islands, Abyssinia, Arabia, and southern Persia. 



4. BRASSICA. 



Brussica, Linn. Gen. n. 820 ; Benth. et Hook. Gen. PI. i. 84. 



A considerable genus of badly defined species, distributed in the temperate 

 regions of the northern hemisphere of the old world. A few occur at the Cape. 



B. rostrata, Balf. fil. in Proc. Roy. Soc. Edin. xi. (1882), 500. 



Herba annua; foliis lyrato-pinnatisectis ; floribus albis ; siliquis patentibus torulosis, valvis 

 trinerviis, rostro longo monospermo.
