sterile fifth between the shorter pair; anther-lobes extremely divari- 
cated; the ovary is small, ‘cylindrical, smooth, seated on a large fleshy 
pulvinate disk, it is 2-loeular, with ovules in a single series, fixed on 
extreme margin of the dissepiment ; style as long as the tube of 
the corolla; stigma 2-lamellate, 
All the South American pinnate-leaved species belonging to Eubig- 
потеа may be classed in З genera, each distinguished by constant and 
easily recognisable characters, viz. :— 
1. Мемова, which may again be divided into sections, 
2. Рекомотомл, differing from Memora in its stipuloid leaves and other 
characters, 
3. PransEoPHORA, where the flowers are each concealed by large investing 
Та Pleonotoma tho calyx is smaller than in Memora, being cylin- 
drical, and often deeply cleft on one side; the corolla is thin and 
membranaceous, ving a narrow basal constriction, is little ventricose, 
le series along each edge of the dissepiment. The branchlets, in 
most instances, are remarkably 4-gonous, often with sharp angles and 
petiole having 2 lateral branches with а Sfid cirrhus at its extremity, 
each of these branches being simply pinnate, or 2 to 3-pinnately divided. 
The genus may be divided into.4 sections :— i
