ones ; petioles 3-9 lines long- : flowers two to five in a group, 

 without a common peduncle; pedicels 3 lines in length; sepals 

 lanceolate, acuminate, about a line long; petals with blades 

 broadly rhombic, entire at the attachment of the hair-like 

 claw, but with four teeth near the apex, the two inner teeth 

 very minute, close to the adnation to the staminal cup, the 

 outer much larger, acuminate, abruptly bent downward and 

 backward ; anthers two-celled ; ovary raised on a slender 

 stipe of 1 line in length; fruit \\-2 lines in diameter, cov- 

 ered with numerous small dark glands. — Head of Mazatlan 

 River, January, 1889 (No. 1307). Differs from A. truncata 

 Rose in its terete branchlets, the longer and more slender 

 stipe of the ovary and in the character of its fruit. 



Mimosa attinis. — Annual, sensitive: stem ascending-, sim- 

 ple or branched, hirsute with spreading or reflexed yellowish- 

 brown hairs and armed with small recurved sub-stipular and 

 scattered spines : petioles an inch long, bearing a single pair 

 of pinnae: leaflets 9-12 pairs, oblong, acutish, 5-7 lines long, 

 the lowest pair appressed-pubescent upon the lower surface, 

 the others nearly glabrous except on the ciliate margins ; 

 stipules awl-shaped, striate, ciliate; stipels bristle-formed, 

 more or less rigid and dark-colored : peduncles shorter than 

 the petioles, bearing small nearly spherical heads 2-2\ lines 

 in diameter; bractlets awl-shaped to bristle-formed, ciliate, 

 exceeding the flowers ; corolla 4-parted ; stamens 4; legumes 

 1-4 seeded, about 6 lines in length, i\ lines broad, the surface 

 minutely pubescent, and the more or less persistent margins 

 provided with numerous very short recurved hooks (\-\ aline 

 in length). — Growing in grassy land among cocoanut trees, 

 Mazatlan and vicinity, January, 1889 (n. 12 18 and 1265). 

 plants having the habit of M. pudica L. differ con- 

 stantly from that species in their smaller heads, and in the 

 characters of the fruit. In M. pudica the legume is ciliate 

 with less numerous, much longer, coarser bristles, which 

 not at all reflexed. Furthermore, the stipels in M. pudica a,, 

 green and much less bristle-like. 



Buddleia (§Globos,E) Wriirhtii. — Shrub: branches and 

 branchlets slender, terete, minutely striate, smooth: eaves 

 thin, lanceolate, sharply acuminate, long-attenuate to a slender 

 slightly margined petiole, serrate, covered on both surfaces with 

 a close and inconspicuous canescent stellate puberulence, green
