I would also refer here Palmer’s Nos, 323, 675, and 676 from Alamos, distributed as 
G.domingensis. This species resembles G, tomentosa, but has very different fruit and 
leaves. 
Colubrina mexicana Rose, sp. nov. 
A small upright shrub, 1.2 to 2.4 meters high; young branches as well as petioles, 
under surface of leaves, pedicels, and calyx pubescent; leaves ovate, long-acumi- 
nate, rounded at base, 3-nerved, entire or with few teeth, 2.5 to 7.5 em. long, includ- 
ing the short petioles (4 to 8 mm. long); flowers 4 to 10 on very short peduncles in the 
axils of the leaves, greenish-white, 4 mm. broad; petals and stamens glabrous; 
fruiting pedicels 6 to 12 mm. long; fruit dry, oval, 4 mm. in diameter; seeds flat- 
tened, 4 mm. long. 
Rich bottom lands; not common. Collected by Dr. Edward Palmer, Culiacan, 
Aucust 27 to September 15, 1891 (No. 1526). 
To this species I would refer also Palmer’s No. 112 (1885) from southwestern Chi- 
huahua referred as ‘* C. glomerata Hems.?” by Watson.! 
This species is clearly distinct from C. arborea in its smaller, more acuminate, and 
more delicately veined leaves and smaller fruit, as well as in the size and habit of 
the plant. 
Cormonema mexicana Rose, sp. nov. 
A small tree, 3.6 meters high, 1.25 dm. in diameter, with stiff branches and axillary 
spines; leaves alternate, oblong to oblanceolate, 7.5 to 15 em, long, including the 
petiole 10 to 14 mm. long, 36 to 65 mm. broad, slender acuminate, narrowly cuneate, 
biglandular at base, entire, glabrous at least in age, pinnately veined; flowers 
unknown; drupes large, mostly 2 in the axils of the leaves on pediceis about 12mm. long. 
Only two trees seen near the mouth of acanyon. Collected by Dr. Edward Palmer, 
Tepic, January to February 6, 1892 (No. 1977). 
It differs from Colubrina arborea, for which it was mistaken at first in the field, by 
having erect branches, pinnately veined leaves, larger fruit, ete. 
Cormonema has heretofore been restricted to a single Brazilian species, C. spinosa. 
The genus is near Colubrina, but differs from it in having spines and in the blade of 
the leaf being biglandular at base. 
The genus is new to the National Herbarium. 
Ccrmonema nelsoni Rose, sp. nov. 
A tree, 4.5 to 6 meters high; older branches with large spines, younger branches 
clothed with brown hairs; leaves alternate, oval to shortly oblong, 5 to 7.5 cm. long 
including the petiole (6 to 12 mm. long), 25 to 35 mm. broad, retuse, the midrib 
slightly prolonged, rounded or broadly cuneate at base; the blade biglandular on 
the margin, slightly hairy on veins beneath, entire, pinnately veined: flowers numer- 
ous in the axils of the leaves, greenish-yellow; petals 5; ovary glabrous, 3-lobed, 
3-celled; cells 1-ovuled; drupes smaller than the last. 
Collected by Mr. E. W. Nelson near San Marcos, State of Guerrero, altitude 500 
feet, February 7, 1895 (No. 2284); also by Dr. Edward Palmer near Lodiego, State of 
Sinaloa, October 9 to 15, 1891 (No. 1625). 
This species differs from C, mexicana in having its branches almost at right angles 
to the stem, the leaves smaller, of different shape, and the glands on the blade 
remote from the petiole. 
Cologania hirta (Mart. & Gal.) Rose; Galactia hirta Mart. & Gal, Bull. Acad. Brux, 
x, pt. 2, 190 (1843). 
Stems twining to 12 dm. high, slender, retrorsely hirsute; leaflets oval or ovate, 
obtuse, yellowish, hirsute beneath, appressed-pubescent above;. flowers clustered 
near the ends of elongated peduncles; bracts and bractlets lanceolate, rather con- 
spicuous; calyx cylindrical, 5 lines long, slightly 2-lipped; the 2 upper teeth united; 
corolla crimson; banner 3 cm. long, tapering at base; keel much shorter, obtuse; 
fruit unknown.
