44 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
calyx 5mm, long; the upper lobe broad, rounded at apex; corolla yellow, streaked 
with purple; pods 5 to 10 mm. long, 2 to 4 seeded. 
Collected by J. N. Rose in the Sierra Madre west of Bolafios, State of Jalisco, Sep- 
tember 15 to 17, 1897 (no, 2972). 
Climacorachis fruticosa Hemsl. & Rose, sp. noy. 
Taller and more frutescent than the last; branches as well as rachis of leaf and 
inflorescence pilose and with shorter glandular hairs; leaflets usually more numerous 
than in the last, sometimes 20 pairs, 7 mm. long, the venation not so strong and more 
frequently 4-nerved; stipules (not seen) caducous or deciduous; inflorescence strongly 
zigzag, about 12-flowered; bracts, bractlets, and calyx glabrous; ovary pubescent; 
pods not seen. 
Similar to CL mexicana but more shrubby, with more numerous flowers, and with 
a different distribution of the pubescence. 
Collected by EK. W. Nelson on mountains near Talpa, Jaliseo, altitude 1,320 to 1,500 
meters, Maréh 7, 1897 (no. 4038).

RAMIREZELLA, A NEW GENUS. 
Ramirezella, gen. nov. 
Calyx small, campanulate, colored; calyx teeth 5, about equal, short, obtuse or 
rounded. Corolla large and showy, purplish and white; standard orbicular with 
scale-like appendages at base; wings auriculate on the upper side; keel much elon- 
gated, at the base erect, but at the middle bent nearly to a right angle, and at the tip 
curved inward. Stamens 10, diadelphous. Style bearded near the end; stigma 
oblique. Pods straight, oblong in outline, turgid, dehiscing; seeds orbicular, embed- 
ded in a white spongy mass of cells. 
Tall, twining woody vines, Leaves pinnate; leaflets 3. Inflorescence a dense 
axillary raceme, at first densely imbricated with large striate bracts; the bractlets at 
the base of the calyx small, ovate. 
A very remarkable genus belonging to the Phaseoleae, the type species having 
been described as a Vigna. From this genus it is abundantly distinct in its habit, 
inflorescence, calyx, keel, fruit, ete. In this opinion Dr. B. L. Robinson, who 
described it as a new Vigna, acquiesces. . 
This genus is named for my friend, Dr. José Ramirez, of the Instituto Medico 
National de Mexico, who is one of the foremost men in natural history in that Republic, 
and who has done much to add to the pleasure and success of my various Mexican 
expeditions. 
Four species are here described, R. strobilophora being the type. 
Ramirezella strobilophora (Robinson) Rose. 
Vigna strobilophora Robinson, Proc. Am. Aced. 27: 167, 1892. 
A twining, woody-stemmed vine 5 meters or more high, the young parts covered 
with a fine soft pubescence; leaflets ovate, acuminate, apiculate, about 8 em. long by 
3 to 4 cm, broad, slightly pubescent above, much paler and densely pubescent 
beneath; peduncles 7 to 9 cm. long; fully developed racemes 6 to 8 em. long; pods 
glabrous, about 12 em. long. 
Collected by G. G. Pringle in a barranca near Guadalajara, September 12, 1891 
(no. 5163), and also in August, 1893 (no. 4503). 
Type locality: ‘‘ Barranca near Guadalajara.”’ 
Some years ago this was figured in the Garden and Forest / and recommended as 
possessing cultural value. It was referred to as follows: 
“Vigna strobilophora, Robinson, sp. nov. is a twining vine with a woody stem 
about an inch thick. It climbs into the tops of shrubs and low trees, and shows
