8. AURICOMA. Caulis superne pube densa seepius aurea hirsutus. Cætera forme præ- 
cedentis. 
C. auricoma, Grah.! in Wall. Cat. Herb. Ind. n. 5322. 
Hab. Tropical Asia, Africa, and Australia, very abundantly, more rare in America. 
The typical form, with small narrow compact leaflets and very small flowers, is exceedingly abundant 
and variable all over the tropical regions of the Old World, where it passes into the larger-flowered 
var. B, of which a rather exaggerated form occurs rarely in tropical America, with as many as fifty 
pairs of leaflets, and is that figured by Colladon as C. hecatophylla, and of which I have seen specimens 
from British Guiana, Appun, n. 796. The var. eschynomene, with rather broader and less erowded leaf- 
lets, of which we have several specimens from the West Indies, Guiana, and North Brazil, distinguished 
. from C. glandulosa and its allies by the glands and venation of the leaves, seems to vary but little in that 
country; but a precisely corresponding East-Indian form, included in C. Wallichiana, passes there very 
gradually into the small-flowered typical C. mimosoides on the one hand, and on the other into the larger- 
flowered and more hairy varieties C. Telfairiana and C. auricoma. | 
. Some specimens of C. Kieinii, with the midrib less marginal, much resemble some varieties of C. mi- 
mosoides, but are readily known by the small stipitate gland. 
928. C. comosa, Vog. Syn. Cass. 65. Herbacea ?, A erecta v. basi decum- 
bens. Foliola oblique v. subfalcato-oblonga, 2-3 lin. lata. Glandula magna, depressa. - 
Cætera C. mimosoidis. 
Chamæcrista comosa, E. Mey. Comm. Pl. Afr. 160. 
Hab. Extratropical South Africa: eastern districts towards Port Natal. 
I have only seen two or three detached specimens which appear referable to this species, of which 1 
have not met with the type. The leaflets are very much broader than in any form known of C. mimo- 
soides, of which they have the venation. 
329. C. SUBTRIFLORA, Mart. ! Fl. Bras. Cesalp. 176. Suffruticosa, undique laxe mol- 
literque pubescens. Foliola valde obliqua, lineari-oblonga. Glandula urceolata. Flores 
majusculi, breviter pedicellati. Legumina patentia, laxe hirsuta. 
Hab. Tropical America: Brazil, prov. Minas Geraes, Ceara, Piauhy, and Rio Negro. 
Very near some of the larger forms of C. mimosoides, but also with something of the habit of C. patel- 
laria, but with much larger flowers. 
330. C. Kirxu, Oliv. ! Fl. Trop. Afr. ii. 281. Molliter villosa, Beo. grandiflora. 
Caetera fere C. mimosoidis var. auricome. 
Hab. Tropical Africa. 
I have some doubts whether this should be regarded as more than an extreme form of C. mimosoides. 
Welwitsch's fine specimens, with broad black sepals, appear as distinct as any Chamecrista ; but there 
are also two specimens from the more eastern districts of tropical Africa which are about intermediate 
between Welwitsch's and some Mauritius specimens of the large-flowered €. mimosoides named by 
Wallich C. Telfairiana.
