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.-' 

 Balsamocarjmf is also a Chilian section, consisting of a single species, 4 

 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 Casalpinias with altogether the flower and fruit 

 of all the preceding species, but whose leaves are simply paripinnate, 

 not bipinnate. 5 But this is insufficient of itself to warrant their 

 relegation to a distinct genus, so that we are compelled to make 

 Cenostigmcf a simple section of Ccesaljrinia, though it has even been 

 placed in a different series — Sderolobiece. Cenostigma has, indeed, the 

 perianth 7 and androceum of the true Casaljjinias, also borne on a 

 receptacle forming a broad inverted cone. The central gymeceum 

 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. 8 The fruit is a flattened, 

 elongated, bivalved pod of nearly wood} r consistency, containing a 

 few exalbuminous seeds. 9 But Cenostigma, like Casalpinia monosperma 

 and marginata Tul., has simply-pinnate leaves. The flowers of the 

 two Brazilian species 10 which form this section are collected into 

 simple or ramified racemes terminating the branches. 



In certain of the Casalpinias 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.

5 This fact has appeared constant in the 

 numerous specimens we have observed of 

 Cczsalpinia monosperma Tul. (in Arch. Mus., 

 iv. 118), which plant we make the type of 

 the section Paripinnaria, but its flowers are 



exactly like those of the other pauciovulate 

 Ccesalpinias.

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 Ccesalpinias. 



8 This stigmatic apex strongly recalls that of 

 certain of the Violar'na ; it occurs in several 

 other Ccesalpinias and in Mezoru urum.
