A pretty little species of the section Quamoclit. In habit and appearance 

 it much resembles Corchorus erodioides, Balf. fil. (see page 39), and occurs with 

 it on the plains. It has much smaller flowers and is altogether a more delicate 

 species than any hitherto described.

Convolvulus, Linn. Gen. n. 215 ; Benth. et Hook. Gen. PI. ii. 874. 



A large genus spread all over the globe, but not so abundant in the tropics 

 as the last. Of the four Socotran species, two are endemic, whilst the other 

 two are restricted to the drier districts of south-west Asia, north Africa, and 

 the Mediterranean region.
