166 BOTANY OF SOCOTRA. 



JEchmolepis, a monotypic and imperfectly known genus from Angola, has 

 sagittate corona scales, but from the description it is very closely allied to our 

 plant, From Ectadiopsis the nonclavate exserted corona scales separate it ; 

 whilst the monotypic south African Ectadium, which is possibly its nearest 

 affinity, has an urceolate or salver-shaped corolla, with subulate corona scales, 

 the anthers cohering and villous on the back, and the inflorescence cymose. 

 The small Madagascar genus Pentopetia has also many technical resemblances, 

 but its habit and appendaged anthers differentiate it. 

 Etym. niros, a thread, and Xem?, a scale.

This plant loses its foliage very early. Our specimens were gathered 

 from a bush in full flower which was almost destitute of foliage leaves. In 

 many features it is not unlike our species of Ectadiopsis, but the technical 

 characters of its corona and of the andrcecium are very different. 



3. COCHLANTHUS.

A monotypic genus of Periplocem, having some affinity with Periploca itself. 

 From that genus, however, it is readily diagnosed by the corolla, corona-scales, 

 and the glabrous anthers. There are two or three other African or Madagascar 

 genera closely allied to Periploca, with which our genus has relations, notably
