6. E. (Tirucalli) Schweinfurthii, Balf. fil. in Proc. Eoy. Soc. Edin. xiii. 

 (1883). 



Fruticosa ramis juveuilibus glabris ; foliis sessilibus elougatis linearibus ; cyinis solitariis

Socotra. Above Kischen at an altitude over 2500 feet. Schweinf. n. 650. 



Distrib. Endemic. 



A plant, of which Schweinfurtli sends fragmentary specimens, I have 

 described as a new species, not having been able to identify it with any known 

 form. It appears to fall into the Tirucalli section of the genus somewhere in 

 the vicinity of E cuneata, Vahl. 



When describing the Socotran Asclepiadacese, I referred to some specimens 

 which I took to be anomalous forms of Ectadiopsis brevifolia, the flowers 

 exhibiting a marked phyllodia ; and this Euphorbia of Schweinfurth's is not at 

 all unlike these.

Socotra. On the Haghier hills south from Tamarida. B.C.S. n. 639.

A very interesting species, of the section Tirucalli, on account of its great
