SOUTH AMERICAN PLANTS. 
SALPICHROA. 
Under this name it is proposed to class several plants that 
have been hitherto arranged in Afropa, the limits of which 
genus remained for a long while undefined, many species 
having been referred to it, and again removed by different 
botanists. Its character, as given by Professor Spenner (Gen. 
Pl. Germ. p. 21, tab. 18) upon the typical species A. Bella- 
donna is deficient in so far as regards all the South American 
species. That offered by Prof. Endlicher (Gen. Pl. n. 3857) 
has evidently been framed with the intention of embracing 
the whole of these, amounting to about ten, which, however, 
include two other very distinct forms; of these, four will be 
classed in Salpichroa, and the remaining six under the name 
of Hebecladus.* The plants before mentioned possess a calyx 
* They are all remarkable for their conspicuous flowers presenting an 
intermediate tooth in the plicature between the lobes of the corolla. The 
generic name of Hebecladus is derived from Sn, pubes, cdadoc, ramus tener, 
- in allusion to their habit, which much resembles that of Salpichroa, but is 
more suffruticose. The following elements for a generic character have 
been taken from the species I have examined in the dried state. 
Hesxciavvs. (gen. nov.) Calyx brevis, profunde 5-partitus, laciniis ovatis 
submembranaceis, 1-nerviis, venosis, persistens. Corolla infundibuli- 
formis, tubo amplo calyce 2-6 plo longiori, fauce ampliato, limbo patenti-
