This species is very closely allied to A. glauca, from which it principally 
differs in the mucli broader legume ; in this about three-fourths of an inch 
broad, in the other not a fourth. We have never met with this species in a 
wild state: it is very common in gardens. 
§ 3. Armed with stipulary thorns: heads of flowers globose. 
854. (13) A. tomentosa (Willd.:) arboreous, armed: branches terete: spines 
stipulary, spreading, often very large and hard: young shoots, petioles, and 
peduncles, clothed with yellowish tomentum: leaves bipinnated ; pinne 
10-12 pair, with an oblong gland below the lowest, and an umbilicate one 
between each of the 1-2 last pair; leaflets 20-80 pair, linear, obtuse, pubes- 
cent on the under side: peduncles axillary, 1-4-together, furnished about the 
middle with 4 small bracteas ; heads of flowers globose : corolla 5-cleft: sta- 
mens numerous, distinct: stigma dilated: legume flat, thin, linear-faleate, 
6-8-seeded.— Willd. sp. 4. p. 1087 ; DC. prod. 2. p. 462; Spr. syst. 3. p. 145 ;

855. (14) A. planifrons (W. & A.:) arboreous, armed ; branches crowded 
at the summit, spreading in all directions, and forming a flat umbrella-like 
top: thorns stipulary, short conical and curved, and very long subulate terete 
or angled and channelled on the sides: leaves bipinnated ; pinnæ 5-6 pair; 
leaflets 10-12 pair, very small, linear, obtuse, glabrous : petioles compressed, 
flat on the lower side, ciliated, without glands: peduncles axillary, agre 
gated, shorter than the leaves, bracteated at the base: heads of flowers glo- 
bose: corolla 5-cleft : stamens numerous, distinct : legumes tumid, somewhat 
terete, spirally eurved.— Wight ! cat. n. 560, 587 (partly).—Mimosa plan

This species approaches Mim. ins of Roxburgh in its foliage and inflo- 
rescence, but the legume is different. Sir J. E. Smith had it before him when 
he wrote his description of M. horrida in Rees’ Cyclopedia, and he evar 
considered it the same as M. eburnea, Roxb., and has marked the specimen 
so ; correetly remarking, however, that Roxburgh's plant was very -— 
from that of Linneeus. Owing to this mistake, his description, partly taken 
from the specimen of A. planifrons, and partly from Roxburgh’s figure of his 
M. eburnea; is applicable to neither. 
856, (15) A. Roaburghii (W. & A.:) shrubby, glabrous, armed : leaves bi- 
pinnated ; pinnee 6 pair, approximated ; leaflets 9 pair, closely approximate 
and almost imbricated : ‘thorns stipulary, often longer than the leaves, united 
at the base: heads of flowers axillary, globose: stamens numerous, distinct: 
legumes linear, variously bent.—Mimosa eburnea, Rowb. ! in herb. Banks: ;

, 857. (16) A. eburnea (Willd.:) subarboreous, glabrous, armed: leaves be 
pinnated ; pinns 2—4 pair, rather distant, with a concave gland between e 
last pair: leaflets 5-8 pair, oval-oblong, obtuse, glabrous, slightly distant 
from each other : thorns stipulary; united at the base, sometimes small, some” 
times very large: peduncles axillary, several together, bracteated about the 
middle: heads of flowers globose, small: corolla 5-cleft: stamens numerous; 
distinct: legume elongated, twisted.—z; pinns; about 4 pair.— Wight peu
