baso, the branches irreguhirly sulfate or angled. Stipules seta- 

 ceous, 2 or 3 mm. long. Petioles very short or wanting, the 

 rachis f) or 6 cm. long, rather stout, lightly costate or angled, the 

 IcaHots mostly 6 or 7 pairs, opposite, subsessile, without stipel- 

 lae, to 5 cm. long and 12 mm. wide, oblanceolate, the summit 

 rounded, mostly slightly emarginate and minutely apiculate ; en- 

 tire, thickish, pale-green, the venation slender, sharply promi- 

 nent on both sides, the secondaries 10 to 15 on a side, nearly 

 straight, ascending at a sharp angle. Racemes terminating the 

 branchlets, elongate, loosely flowered, the rachis sharply angled. 

 Bracts about half as long as the pedicels, lance-linear, acuminate 

 and acute. Pedicels about 3 mm. long, slender. Calyx-tube 

 about 2 nun. long, 3 mm. broad, campanulate, about as long as 

 the shortest tooth and two thirds as long as the longest, the teeth 

 triangular-ovate, slenderly acuminate, rigid. Vexillum 12 mm. 

 long, 1 cm. broad, emarginate, the claw 1 or 2 mm long, broad, 

 the base of the limb broadly rounded or subtruncate. Wings 

 almost equaling the vexillum, their claws adnate to that of the 

 keel. Keel shorter than the "vvings, the broad summit incurved, 

 the stigma exserted. Stamens shorter than the keel, the free 

 portions of the filaments short and slender. Ovary elongate, 

 tapering into the style, hirsute. Style inflexed at a right angle. 

 Legume 4 or 5 cm. long, 4 mm. wide, linear, almost straight, the 

 margins narrowly thickened, the persistent slender, straight 

 style 5 or 6 mm. long. Seeds 10 to 12.

No. 1312, collected in copses in the same region, may prove to 

 be a variety of the same. Its flowers are rose-colored, the vexil- 

 lum much broader. The plant is much more hairy, with the hairs 

 more spreading. There are only 8 or 10 leaflets. The calyx teeth 

 are larger and broader and the legume is narrower, with smaller 

 seeds. 



Meibomia microcarpa 



Tomentellate, the slender ascending stems roughish, the 

 lower leaf surfaces softly so, the branchlets more or less angled 

 or costate. Stipules caducous, thin, brownish, shorter than the 

 petioles, subulate, acuminate. Leaves 1-foliolate, the petioles 

 5 to 7 mm, long, the stipellae minute, linear. Leaflets 3 to 5 cm. 

 long, 1.5 to 2.5 cm. broad, ovate-oblong, with rounded or sub- 

 cordate base and blunt or rounded and minutely apiculate sum-
