Nom. Vern. Dhael (Schweinf.). 



Socotra. The commonest plant of the plains at Galonsir and Nogad. 

 B.C.S. n. 14. Schweinf. n. 252. 



Distrib. Endemic. 



Amongst the true Inulece, to which tribe our Socotran plant undoubtedly 

 belongs, I have had some difficulty in finding a genus to which it might be 

 referred. For whilst with none of them do its characters entirely agree, yet it 

 possesses some of the features of several closely-allied genera. At one time I 

 considered that it might form the type of a new genus, for the achenes are 

 very different from those in any in this tribe, but for the present I am content 

 to place it in Pulicaria. 



From the technical characters of the genus it diverges in some particulars. 

 The heads are homogamous, which is not a character of Pulicaria, although 

 sometimes they are disciform; the anther-tails are connate in pairs, a feature 

 unknown, so far as I am aware, in Pulicaria, except in the Socotran species just 

 described, — P. diversifolia, — and the achenes are very strongly angulate, with 

 prominent ribs, not terete as in typical species. In its pappus, too, it differs, for 

 the inner setoe are somewhat flattened. In this latter character, as well as in 

 that of the shrubby habit, connecting links with typical Pulicarice are supplied 

 by those half shrubby forms from the desert plains of the east, originally 

 described by Boissier (Diagn. i. vi. 76) under Pterochwta [subsequently changed 

 to Platyckceta (Diagn. i. xi. 5, and Flor. Orient, iii. 207)], on account of the 

 flattening of the pappus, but now referred by Bentham and Hooker to Pulicaria. 

 T. Anderson's Aden plant, Vartheimia arabica (T. Anders, in Journ. Linn. Soc. 

 v. (1866), Suppl. 23), is one of this group.
