broad, retuse : ovary uniovulate ; legume pendulous, somewhat trape- 
zoidal, 1-seeded, membranous, acuminate at the apex, finely pubescent, 
ciliated on the margin, about half an inch long. — Collected in the 
barranca of Tequila, Jalisco, 13 October, 1893 (no. 5446). This 
Species is exceptional in Phaseolus in possessing 1-seeded legumes, but, 
differing from this genus in no other regard, should doubtless be 
referred hither, especially since in the closely related P. filiformis, 
Benth., there are sometimes but two seeds in the pods. 
VIGNA sTROBILOPHORA, Rob. (Proc. Am. Acad. xxvi. 167.) 
Specimens of this plant collected in a barranca near Guadalajara, 25 
August, 1893 (no. 4503), furnish the following supplementary charac- 
ters: stems woody, an inch or more thick, climbing to the tops of 
shrubs and trees: legumes smooth, 4 inches long, half an inch in 
breadth, acuminate; seeds ellipsoidal, dark purple, mottled, almost 
black. This plant has been figured recently in ‘ Garden and Forest,’ 
vii. 155. 
C2SALPINIA Mexicana, Gray, var. PUBESCENS. Branchlets and 
both surfaces of the leaves when young soft-pubescent : petals beau- 
tifully ciliolate with stipitate glands: pod rather short and broad, free 
tom the punctation commonly if not always present in the typical form. 
— Collected on dry hills near Zapotlan, 25 May, 1893 (no. 5467). 
SchizocaRPuM PARVIFLORUM. Stems very slender, furrowed, 
finely pubescent ; internodes elongated: leaves cordate-ovate in out- 
line, denticulate, green and sparsely appressed-pubescent above, slightly 
paler and more densely appressed-pubescent beneath, varying from 
3-5-toothed to deeply 3-lobed ; lobes apiculate, the terminal one often 
considerably exceeding the others: tendrils unequally 2-branched: 
peduncles pubescent, 3 lines to an inch long: free lobes of the adnate 
calyx filiform, 1-13 lines long: the yellow campanulate corolla 8-12 
lines in length, finely glandular-pubescent upon the outer surface, Saft 
pubescent within, ciliolate upon the margin ; segments ovate, obtusish, 
Sometimes apiculate, 3(-5)-nerved : filaments about 2 lines in length, 
equalling the anthers: fruit flask-shaped, nearly 2 inches in length, 
puberulent. — Collected on talus of cliffs, barranca of Tequila, Jalisco, 
3 October, 1893 (no. 4555). Very similar in habit to S. Jiliforme, 
tad., but with flowers about half as large. 
Coutreroruytum taxum, Rob. (Proc. Am. Acad. xxvii. 169.) 
A younger specimen, collected in the barranca of Tequila, 6 July, 
1893 (no. 5537), shows the following additional characters: flowers 
Yellowish-green ; petals broad at the base, abruptly contracted to a 
slender, incurved tip. :
