Planta Lindheimeriane. 181 
ground. Leaves crowded. Leaflets an inch or less in 
length, one to two lines wide, rather rigid, as long as the 
petiole. Peduncle one or two inches long, slender. Corolla 
two thirds of an inch in diameter, pale yellow in the speci- 
mens. The seven perfect anthers open by a terminal pore; 
the three upper stamens are abortive, as in the section Cha- 
meesenna, to which, so far as can be told in the absence of 
the fruit, this species would seem to belong,

Common on the Guadaloupe, &c. May, in flower; August, 
with unripe fruit. — The Muskit “forms open woods in 
high, rocky plains, and wet, clayey bottoms. ‘Trees from 30 
to 40 feet high, with few and large, erect branches; the 
trunk often from one to two and a half feet in diameter ; 
the heart-wood dark reddish brown; but often occurring as a 
small tree or shrub. Important as furnishing the only fire- 
wood in Western Texas; also for its edible fruit." Lind- 
heimer. — The foliage appears different from that of A. dulcis, 
Benth., in Hartweg’s Mexican Collection.

— Rocky plateaus near New Braunfels, and on the Upper 
oupe, not seen on the Pierdenales. July, in flower, 
and with young fruit: August, with ripe fruit. — Shrub two or 
three feet high; the branches armed with very stout, com- 
pressed, infrastipular aculei, which are sometimes solitary, 
germinate, often usually in threes. Occasionally there are one 
or two minute prickles on the rachis of the leaves. Calyx 
purple, very glabrous. This species is nearly allied to M. 
acanthocarpa, of Mexico, from which it differs in the want
