LEGUMINOSZ-CHISALPINIEA. 15 
scarcely prominent, the vegetative organs are unarmed, and the 
calyx is sometimes fringed and glandular at the edges. These glands 
become very prominent and fringe the inferior sepal in Coulteria, of 
which some have hence wished to make a separate genus; it consists 
of two species of unarmed trees, the one Mexican, the other Chilian. 
Balsamocarpon! is also a Chilian section, consisting of a single species," 
with a slightly irregular corolla, a thick subtorulose fruit, and a 
fimbriate calyx whose outer surface is covered with glandular hairs ; 
the leaves are altogether those of Pomaria. 
There are some Cesalpinias with altogether the flower and fruit 
of all the preceding species, but whose leaves are simply paripinnate, 
not bipinnate. But this is insutficient of itself to warrant their 
relegation to a distinct genus, so that we are compelled to make 
Cenostigma’ a simple section of Cesalpinia, though it has even been 
placed in a different series—WSclerolobiee. Cenostigma has, indeed, the 
perianth’ and androceum of the true Cesalpinias, also borne on a 
receptacle forming a broad inverted cone. The central gyneceum 
consists of a subsessile pauciovulate ovary, bearing a style whose tip 
is by a little opening with ciliate edges leading to an irregularly 
sacciform cavity of variable depth.’ The fruit is a flattened, 
elongated, bivalved pod of nearly woody consistency, containing a 
few exalbuminous seeds.’ But Cenostigma, like Casalpinia monosperma 
and marginata Tun., has simply-pinnate leaves. The flowers of the 
two Brazilian species” which form this section are collected into 
simple or ramified racemes terminating the branches. 
In certain of the Cesalpinias with an indehiscent fruit whose edges 
taper into a narrow blade, the style is dilated at the tip into a sort 
of peltate disk ; whence the name Peltophorum™ given to this group.

7 The calyx is sometimes denticulate and 
glandular on the edges. The anterior sepal is 
usually the most concave and the largest of all, 
as in most of the true Cesalpinias. 
8 This stigmatic apex strongly recalls that of 
certain of the Violarive; it occurs in several 
other Cesalpinias and in Mezoneurum.
