134 BOTANY OF SOCOTRA. 



flower heads are small, I inch long, and contain very few — rarely 10 — flowers, 

 which Schweinfurth says are white. 



d. stoloniferum, Balf. fil. in Proc. Eoy. Soc. Edin. xiii. (1883). 

 Stolonifera, capitulis majoribus multifloris solitariis, phyllariis exterioribus brevibus ovatis, 

 interioribus longis spathulatis acutis. 



Soeotra. Hills south-west from Galonsir. B.C.S. 238. Nimmo. 



This is the form we found most common on the hills south-west of Galonsir. 

 It consists of a number of small rosulate herbs united by long delicate stolons, 

 and sending up a few arcuate branches, each of which ends in a long (often 

 2-3 inches) thin peduncle supporting a solitary capitulum. The capitula are large, 

 over £ inch long, 30-40-flowered, and with a many -leaved, many-rowed involucre, 

 the outer phyllaries of which are short and ovate, the inner long spathulate and 

 acute, with the narrowed lower part thickened and green-ribbed. They are 

 only slightly woolly. This is the most divergent from the type, but though the 

 involucre and the size of the heads, with the long peduncles, are very marked 

 characters, they are hardly specific. 



9. PULICARIA. 



Pulicaria, Gartn. Fruct. ii. 461, t. 173, f. 7 ; Benth. et Hook. Gen. PL ii. 335. 



An old world genus of twenty-five to thirty herbaceous or shrubby species, 

 occurring in Europe, Africa, and the eastern parts of Asia. One species occurs 

 at the Cape of Good Hope, but the Mediterranean region is their centre. The 

 three Socotran species are endemic.
