other, I have not yet seen any specimens which [I am disposed to refer to it. Some 
Mexican collector should visit the type locality, which can now be easily reached, 
and obtain a supply of material. 
Cologania? affinis Mart. & Gal. Bull. Acad. Brux. 10%: Iss. 1845, 
Collected by Galeotti (no. 3283) in oak woods near ‘Mirador.’ Not. since 
reported. 
Described as climbing; retrorsely villous; leaflets ovate, obtuse, appressed-pubescent, 
glaucescent beneath; flowers axillary, some fasciculate; calyx pilose. 
See Seaton’s no, 826 and Pringle’s no. 8605. 
Cologania ovalifolia H. B. K. Noy. Gen. & Sp. 6: 412 (royal ed. 233). 1825. 
This is a South American species which was identified with a Mexican plant by 
Schlechtendal @ but should probably be excluded from the Mexican flora. 
Martia mexicana Zuce. Abhand]. Akad. Muench. 1: 339. pls. 14, 15, 1882. 
Type locality: “In imperii Mexicani regionibus calidioribus;’’ type collected by 
D. Keerl. 
I have not been able to make out this species. It resembles very much Watson’s 
C. martia, as well as specimens from the valley of Mexico which I have referred to 
C. intermedia, 
LIST OF THE SPECIES OF HARPALYCE WITH TWO NEW 
DESCRIPTIONS. 
The genus Harpalyce is very similar in foliage, habit, and pods to 
Brongniartia and the only reason that it is not more frequently 
misnamed in herbaria is that it has not often been collected. It is 
readily distinguished, however, by its having a remarkable two-lipped 
calyx, while Brongniartia has a nearly regular calyx. It can also be 
readily distinguished from Brongniartia without flowers by the leat- 
lets which are thickly set with pellucid dots. 
In publishing the two new species below I have taken occasion to 
list with them all the known, I might better say the little-known, 
Mexican species with the hope that Mexican collectors may furnish 
us with more material. 
Harpalyce mexicana Rose, sp. nov. 
A small tree; bark of old wood smooth, densely covered with small pale lenticels; 
young wood coyered with a dense white pubescence; rachis very pubescent; leaflets 
11 to 15, oblong, 3 to 6 em. long, rounded at base, obtuse, apiculate, in age nearly 
smooth, beneath somewhat pubescent, thickish and reticulated; fruit oblong, 5 to 6 
em. long. 
Collected by J. N. Rose, west of Bolafios, September 15 to 17, 1897 (no. 2944). 
Harpalyce pringlei Rose, sp. nov. 
A low shrub 3 to 18 dm. high; all parts very pubescent when young; leaves 1 to 2 
dm. long; stipules minute, caducous; leaflets 7 to 11, oblong, 2 to 4 cm. long, 15 to 
20 mm. broad, rounded at base, retuse, thickish, strongly veined, above nearly 
glabrate, beneath quite pubescent when young, becoming glabrate in age, with 
pellucid dots as in the genus; flowers in dense short clusters; sepals densely reddish- 
pubescent; petals bluish; legume glabrous, oblong, 8 em. long, 2 to 2.5 em, broad. 
Collected by C. G. Pringle on the sides of a barranca above Cuernavaca, Morelos, 
1898 (no. 6827, type), and at the same station by J. N. Rose, May, 1899 (no, 4392).
