This is a common tropical species, and subject to much variation of form. "The type 
specimens in the Linnean herbarium have been specially inspected for comparison. Our 
specimen is a form with very slender stems and branches and small leaves, thus approach- 
ing the typical form of Е. alsinoides, L., but with the narrowly lanceolate shape of its 
leaves as іп Æ. linifolius, L.

The species quoted above occurs in the Transvaal. The type, collected by Burke, in the 
Kew herbarium agrees with our specimen. Тһе specimen of Burchell, quoted by Nees 
l. c., we do not find in the Kew herbarium ; the name of Burchell was probably printed 
by mistake for Burke. The species does not appear to have been noted by T. Anderson, 
іп Journ. Linn. Soc. Lond. vii. p. 34 (1863), among the South-African species of the 
genus.
