A very distinct species. its pinnalisect leaves quite unlike thèse of 

 any other described Iphion. 



Pentatrichia petrosa Kiatt (ex le. et descript.). 



Deutsch-Südwest-Afrika : Gross-Namakmd, Graspoort. Dinter 1225. 



Thoiigh this genus is not accepted by 0. Hoffmann am strongly of 

 opinion fhat it should be kept up. Hoffmann goes even further than 

 did Benlham in merging neighbouring genei'a before their fime con- 

 sidered valid, for not only does he acquiesce in the union of Pentanema 

 and Vitra, but lie sinks them in, stränge to say, Imila, and deals the same 

 fate to Bojeria and Pentatrichia, thus making what I cannol but regard 

 as a most unnatural genus. Surely if we can getwell-pronounced pappu.s- 

 characters, they onght to be made use of in classification; and thongh 

 Pentanema is undoubtedly close to Vicoa, its five strongly pubescent 

 pappus-hairs should. I consider, amply suiflce to mai'k it off from this 

 latter. The pappus of Pentatrichia is quite a peculiar one. and the 

 affînity of the genus seems to me fo be with Pulicaria,- in fact il hoids, 

 ronghly speaking, to Puliearia the same relation that Nicolasia does to 

 Pluchea. it may be added thaf Pentatrichia has a double pappus, an addi- 

 tional reason for not merging il in Inula.

Differs from M. Banmii 0. Hoffm., known to me by description only, 

 in shape and size of its markedly petiolate leaves. in the narrower invo- 

 1 lierai leaves, the single arista to the ovaries of ihe disc-florets, and 

 fhe muticous achenes.
