The following brief description has been drawn up from the sped- Description, 
mens in Herbarium Debra of plants cultivated in India :— 
Habit —Small tree or large shrub. 1 With or without straight, 
stout, more or less extra-axillary spines i—2 in. long. 
Leaves —'Alternate, or fascicled on stunted branches, 2-pinnate. 
Stipules small, lanceolate to subulate, deciduous or 
persistent. 
Petiole |—5 in. long, glabrous. 
Rachis (excluding petiole) f—2J in. long, glabrous, apex 
spinescent, a gland at base of each pair of pinnae. 
Pinnce 1—2 pair, opposite, 2— 6f in. long, with or without 
glands at base of upper leaflets. 
Leaflets 9—20 pair, opposite, sessile or subsessile, linear, 
reticulate, apex acute or obtuse, glabrous. 
Length \ — in. 
Width 0-05—0-25 in. 
Flowers —Shortly pedicelled in cylindrical, spiciform, axillary 
racemes. 
Peduncle \—1 in. 
Raceme 2—3*5 in. long (excluding peduncle). 
Bracteoles small, obovate to rounded, sparsely villous, deciduous. 
Pedicels 0*02—0*03 in. 
Calyx valvate, campanulate, i the corolla, 5-toothed or slightly 
lobed, a few short hairs, chiefly near the margins of the 
teeth, otherwise glabrous. 
1 Professor C. S. Sargent, l.c., notes as follows on the habit of this species: “ a low tree, 
with a large thick taproot descending frequently to the depth of 40—50 ft. and furnished 
with radiating horizontal roots spreading in all directions and forming a dense mat, a trunk 
6—8 in. diameter, divided a short distance above the ground into many irregularly arranged 
crooked branches forming a loose straggling head * # more often a shrub, with numerous 
stems only a few feet high.” The following information is available regarding the growth 
of the plant in India : “ The trees (at Umballa and Jalundur) were about 3 or 4 ft. high 
in about a year’s growth, and had long straggling branches.” (Indian Forester , Vol. V, p. 
332.) “ The Saliaranpur plants are 6 years old, and are bushes with a loose straggling habit 
from 15 to 20 ft. high, but with no appearance that would lead one to suppose they will 
grow into trees from 40 to 60 ft. high, and produce marketable timber.” (Indian Forester , 
Vol. X, p. 369.) See also note on page 4 above. Most of the plants now in cultivation 
in India appear to have been raised from seed obtained in North America. Information does 
not seem to be available as to whether better results in the way of height growth and timber 
production were obtained from the consignment of seed sent from Jamaica, see p. 3 
above.
