2. Cologania erecta Rose, Contr. Nat. Herb. 5: 136. 1897. 
Stems from a woody base, erect, 7.5 to 15 em. high, with rather close, erect 
pubescence; leaflets elongated, 10 to 15 cm. long, 4 to 8 mm. wide, rounded at base, 
somewhat tapering toward apex, but with obtuse apiculate tip; calyx 4 mm. long; 
pod 2.5 to 3.7 em. long, 3 mm. wide, pubescent. 
Type locality: ‘Near Guadalajara.”’ 
Collected by Mr. C. G, Pringle on rocky hills near Guadalajara, June 21, 1893 
(no. 4401). 
3. Cologania intermedia H. B. K. Nov. Gen. & Sp. 6: 414. 1823. 
Type locality: ‘‘ Prope Real del Monte, Mexicanorum;’’ collected by Humboldt & 
Bonpland. 
Specimens examined: 
Federal District: Valley of Mexico near Tizapan, Bourgeau, 1865-66 (no. 328); 
same locality, C. G. Pringle, August, 1897 (no. 7480); near Tlalpam, J. N. 
Rose, June, 1899 (no. 4530); Santa Fé, May 24, 1899 (no. 4321); same 
loeality, July 11, 1901 (no. 5359), 
Jalisco: Road between Mesquitee and Monte Escobado, August, 1894 (no. 
2610). 
Very near to C. angustifolia, to which Mr. Hemsley referred Bourgeau’s plant, but 
with the upper surface of the leaves glabrous. 
4, Cologania longifolia Gray, Pl. Wright. 2: 85. 1853. 
Type locality: ‘‘ Hills near the copper mines, New Mexico. . . . Mountain 
ravines, on the Sonvita, near Deserted Rancho, Sonora.’’ 
5. Cologania angustifolia Kunth, Mimos. 209. p/. 58. 1819. 
Type locality: ‘* Prope La Magdalena,’’ between Real del Moran and Actopan, 
Hidalgo; type collected by Humboldt & Bonpland. 
Deseribed in part as follows: Stems climbing; leatlets 5, linear, obtuse, on both 
sides, strigose; calyx hispid-pilose. 
Specimens of the writer’s referred here have the leaflets sometimes 10cm. long and 
5mm. broad, the calyx covered with upwardly turned appressed hairs, the upper 
lobe of the calyx varying from acute to retuse, and the pods somewhat falcate. They 
may, however, represent a different species. 
Collected by J. N. Rose in foothills of the Sierra Madre, near Colomas, State of 
Sinaloa, July 14, 1897 (no. 1653); on Sierra Madre west of Bolaiios, State of Jalisco, 
oF 
September 16, 1897 (no, 3720), and in State of Durango, August 15, [LS897. 
6. Cologania confusa Rose, sp. nov. 
Low plant with slender stems either trailing or climbing; leaflets 5, linear, pubes- 
cent on both sides; calyx tube 6 mm. long, with spreading pubescence; pod talcate, 
about 35 em. long. 
Collected first by C. Wright in 1851 probably from near E] Paso, Texas (no, 958, 
type), and more recently by Mr. G, C. Nealey in western Texas (no. 591a). 
This species was taken for C. angustifolia Kunth by Dr. Gray and was reported by 
him in Plantee Wrightianze under this name, by which it has ever since gone. It 
differs from (. angustifolia, however, in its range, in its smaller flowers, and in the 
pubescence of the calyx. Dr. Gray states that he had not seen Kunth’s illustration 
and description. 
7. Cologania deamii Fernald, Proc. Am. Acad. 26: 492. 1901. 
Stems low and twining, pubescence reflexed; leaflets 3, broadly oblong, 2 to 3 em. 
long, 1.2 to 1.5 em. broad, apiculate, when young densely reddish-pubescent on both 
sides, the pubescence more scattered and appressed in age; flowers (at least the 
earlier ones) in umbels of two or four on peduncles sometimes 3 cm. long; pedicels 
1 to 1.5 em. long; bractlets filiform, usually borne some distance below the flowers;
