Distrib. Endemic. 



An interesting indigenous species, distinguished by its trifid leaves, few- 

 leaved involucre, and hispid achenes, from E. arabicus, Steud. (in herb. Schimp. 

 Arab. n. 852 ; Jaub. et Spach 111. PI. Or. iv. 88, tt. 355, 356), and from E. 

 pinifolius, Ach. Rich. (Tent. Flor. Abyss, i. 445, t. 60), the only two species,— 

 and they are doubtfully distinct, — which are found beyond the Cape of Good 

 Hope. Possibly its nearest ally is E. trifurcatus, Cass. (Harv. and Sond. Flor. 

 Cap. hi. 411), in which, however, the flower heads are larger, the phyllaries more 

 numerous, and the achenes are villous. 



16. TRIPTERIS. 



Tripteris, Less, in Linnsea vi. (1831), 95 ; Bentb. et Hook. Gen. PL ii. 455. 



Essentially a Cape of Good Hope genus of about thirty herbaceous species. 



One is, however, found in south tropical Africa, and two occur in north tropical 



Africa, one of which extends to Socotra.

A basi rnultirainosa ; foliis plerumque oblanceolatis angustis ; capitulis minoribus £ poll, 

 longis ; involucri bracteis oblongo-ellipticis acutis ^ poll, longis ; floribus flavis radii ligula 



poll, longa ; acbeniis £ poll, longis. 



Socotra. Common near Galonsir and Tamarida. B.C.S. n. 74.

Distrib. Of the species — Upper Nubia. Of the variety — endemic. 



The type of this species is represented in Kew Herbarium by a few 

 specimens collected by Lord at Hor Tamanib. Our plant differs in being a 

 more freely branched form, with much smaller flowers and fruit, and I have 

 made it a distinct variety. On Lord's ticket is the remark — " blue flowers, very 

 showy." The appearance of the dried flowers belies this, and I am pretty 

 certain they must be yellow, as are those of our Socotran plant.
