E. pendula (Liukj Enum. PI. Hort. Berol. ii, 10) ; stems long and 

 pendulous, forking at distant intervals, about 2 lin. thick, terete, 

 succulent, glabrous ; leaves opposite, rudimentary, minute, deltoid, 

 acute, closely adpressed to the branches. Botss. in DC. Prorlr, xv,

This plant has been supposed to be a native of South Africa, but I have not 



seen any specimens from that region which at all resemble it. I believe it to be 



Sarcostemma brunonianuin, Wight and Aniott, a native of India. It is a very old 



garden plant, whose flowers are unknown. During my 42 years' knowledge of the 



plant at Kew, I have never seen it in flower, so that it evidently flowers very rarely 



under cultivation. In Januar^^ of this year (1915), however, a friend forwarded to 



me a sketch of a flower, which developed upon a plant of " Eaphorhia pendula,'* 



cultivated by another lover of succulent plants. This drawing undoubtedly 



represents the flower of an Asclepiad and apparently of the genus Sarcostemma, 



but is too imperfect to conflrm the opinion above expressed of its specific 

 identity. 



E. viminalis (Linn. Sp. PL ed. i, 452, and Amcen. Acad.iii. 110 ; 

 Mill. Gard, Diet. ed. viii. no. 15) is Sarcostemma viminale, R. Br.
