Socotra. Common on the hill slopes and also on the sea-shore. B.C.S. 

 nn. 83, 238. Schweinf. nn. 307, 470, 762. Nimmo. 



Distrib. Endemic. 



A third species, known hitherto only by Dr Nimmo's specimens, and 

 described by Oliver and Hiern (loc. cit.). As it occurs on Socotra, and it is 

 abundant, it is very variable in habit, clothing, and size of parts. We have the 

 following forms : — 



a. genuinum. B.C.S. n. 83. Schweinf. n. 762. 



The specimens most typical are those gathered by Schweinfurth at Wadi 

 Kischen, altitude 1900-3000 feet. But his plants are more robust than those 

 of Nimmo. We obtained plants on the Haghier range, above Tamarida, 

 resembling closely the type, being less stout than Schweinfurth's, but the 

 achenes are quite glabrous, not puberulous as described. 



b. lanatum, Balf. fil. in Proc. Roy. Soc. Edin. xiii. (1883). 

 Dense lanatum, pedunculis brevibus, acbeniis glabris. 



Socotra. Shore near Tamarida. Schweinf. n. 327. 



Schweinfurth's specimens, from the sea-shore near Tamarida, show a more 

 woolly plant, and one with thicker leaves than usual. The woolliness is especially 

 evident upon the involucre. The peduncles of the capitula are very short in this 

 form, and the achenes are glabrous. 



c. profusum, Balf. fil. in Proc. Eoy. Soe. Edin. xiii. (1883). 



Foliis submembranaceis, capitulis parvis paucifloris in paniculos ramosos dispositis, pedicellis 

 erectis. 



Socotra. Near Keregnigiti. Schweinf, n. 470. 



A single specimen, sent by Schweinfurth, differs from the forms already 

 mentioned in its erect, patent, and more slender character. The leaves are 

 large and thin, almost membranaceous, and the capitula are arranged in much 

 branched panicles, the ultimate peduncles being erect and very fine. The
