Our specimens differ in respect of habit and the shape of the leaves, 
etc., from the description of the species quoted above, but they fairly 
agree with a poor specimen of the type seen in the Kew herbarium. 
The following perhaps belongs to the same species :— 
Huitia.—Annual. In fields near Lopollo, rather rare; fr. Feb. 
1860. Cox. Carp. 636.

A tender little annual herb, 3 to 4 in. long; stem weak, bright 
green ; leaves membranous, bright green ; calyx campanulate, adnate
