38 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
calyx 5 to 7 mm. long with pubescence of spreading hairs; upper lobe retuse; corolla 
2 cm. long, purplish; pods (immature) linear, 4 cm, long, pubescent. 
Type locality: ‘‘Cuernavaca,’’ Morelos. 
Specimens examined: . 
Morelos: Near Cuernavaca, J. N. Rose, May 27 to 80, 1899 (no. 4360), and Charles 
C, Deam, July 7, 1901 (no. 40, type). 
8. Cologania scandens Rose, sp. nov. 
Stems climbing, pubescent; leaflets ovate, 3 to 8 em. long, rounded at base, acute 
or obtuse and mucronate, appressed-pubescent on both sides, strongly nerved; per- 
fect flowers in pairs; calyx tube about 6 mm. long clothed with whitish appressed 
hairs; flowers violet. 
Collected by J. N. Rose on the road between Colotlan and Plateado, August 31, 
1897 (no. 3618, type), and near Huejuquilla, August 25 (no. 3781). Perhaps nearest 
C. pulchella, but with rougher pubescence on the leaves, different pubescence on the 
calyx, ete. 
9. Cologania rufescens Rose, sp. nov. 
A slender climbing vine, covered with reddish and somewhat spreading hairs; leaf- 
lets 3, ovate, acute and apiculate or shortly acuminate, appressed brownish pubescent 
on both sides; calyx tube 10 mm. long, covered with spreading reddish hairs; lobes 
much asin ©. glabrior; fruit not seen. 
Collected by Heyde & Lux in Chiul, Department of Quiché, Guatemala, Septem- 
ber, 1890, and distributed by John Donnell Smith (no. 4460). 
This species was distributed as a variety of C. pulchella under a hitherto unpublished 
nam>, which is here adopted. It seems very distinct from true pulchella, 
10. Cologania glabrior Rose, sp. nov. 
Slender climbing vine; leaflets 2 to 6 cm. long, 1 to 4 mm. broad, ovate to oblong, 
very thin, greener and only slightly pubescent above, paler and appressed pubescent 
beneath, acute or sometimes obtuse at apex, rounded at base; flowers axillary, in 
pairs; buds long-acuminate; calyx tube 7 to 8 mim. long, covered with rather scanty 
appressed hairs; lateral lobes ovate and acuminate; dorsal lobe broader and acute; 
lower lobe linear. 
Collected by Heyde & Lux, Lagrena de Ayarza, Department of Jalapa, Guatemala, 
September, 1892, and distributed by John Donnell Smith (no. 3743); perhaps from 
the same locality, Heyde, 1892 (no. 454, type). 
Mr. Smith’s specimen was labeled by Micheli with the trivial name adopted 
above, but simply as a form of pulchella. It must, however, be very different from 
that species, which comes from central Mexico. 
11. Cologania jaliscana Wats. Proc. Am. Acad. 26: 136. 1891. 
C. pringlee Wats. Proc. Am. Acad. 25: 147. 1890, not 23: 271. 1888. 
Type locality: Near Guadalajara ‘“‘Jalisco;’’ type collected by Mr. C. G. Pringle 
(no. 2788), 
12. Cologania pallida Rose, sp. nov. 
Stems slender, climbing, pubescent; leaflets oblong to elliptical, usually acute, 
always apiculate, 2 to 38cm. long, very pale and cinereous-pubescent on both sides; 
flowers solitary (in specimens seen) on slender peduncles 6 to 8 mm. long; bractlets 
subtending the calyx filiform; calyx tube 6 mm. long, with pubescence somewhat 
scattered, spreading and stiff; fruit not seen. 
Collected by C. Wright in New Mexico in 1851 (no, 957, type) and by G. R. Vasey 
in the Organ Mountains of New Mexico in 1891. This plant was called C. pulchella 
by Dr, Gray, under which name it has since gone. Dr. Gray, however, seems to 
have been uncertain of its status, in one place stating that it perhaps was a different 
species and elsewhere that it was only a variety.
