Meibomia longiarticulata 



TJoii^liisli-hairy, Avitli ratlicr eoarso, diverf;-ent hairs. Stems 

 IKirplisli, rather stout, nerved, inuch-l)ranched, the l)ranchk'ts 

 rather short, green. Stipules subulate, acuminate, acute, half 

 the length of the petioles, thin, brown, deciduous, the stipellae 

 similar. Leaves trifoliolate, the petiole 5 to 7 mm. long, the 

 rachis nearly as long, the petiolules about half as long. Lateral 

 leaflets 3 to 10 cm. long, 1 to 3.5 cm. wide, lanceolate, with 

 rounded or blunt base and summit, the latter minutely apiculate ; 

 thiekitili and rigid, bright-green on both sides, all the venation 

 slender, the secondaries about 6 or 8 on a side, strongly ascend- 

 ing, the venation loosely but prominently anastomosing. Inflor- 

 escence paniculate, the racemes rather densely flowered, the 

 caducous bracts, similar to the stipules, but smaller, the flowers 

 mostly 3 to 5, racemose on a short branchlet. Sepals 1 to 2 mm. 

 long, ovate, obtuse, the two lower wholly connate, the others at 

 the base only. Standard 1 cm. long, 7 to 8 mm. wide, obovate, 

 the l)ase regularly narrowed, without claw. Filaments distinct 

 for about one fourtli of their length. Pods (always?) 2 or 3- 

 jointed, the sinuses equally intruded on both sides, the joints to 

 2 cm. long and 5 imn. wide, oblong, thin, the margin thickened, a 

 slight indentation on one side where the seed is attached. 



Covendo, 2,000 feet, 0. E. White, September 12, 1921 {no. 

 1055). 



Amerimnon ovale 



Inflorescence, etc., minutely pulierulent, the lower leaf-sur- 

 faces almost imperceptibly so. Branchlets short, stout, crooked. 

 Stipules and stipellae not seen. Petioles about a fourth of the 

 length of the leaf, mostly erect, stout. Leaflets about 7, alter- 

 nate, the petiolules 5 mm. long, rather stout, flattened above. 

 Blades to 8 cm. long and a fourth to a third as wide, oblong or 

 oblanceolate with rounded base and slightly produced at the 

 summit into a very short and broad, mostly refuse point, entire, 

 thickish, drying brown, deep-green and shining above, pale be- 

 neath, the principal secondaries al)out 15 on each side, with as 

 many smaller intermediate ones, the venation prominent on both 

 surfaces, more so on the upper surface, the venation extremely 

 finely anastomosing and of a reddish or purple color beneath. 

 Corymbs axillary, puberulent, about 3 cm. long and broad, the 

 peduncle about as long as the flowering portion, very slender. 

 Flower 5 mm. long, the calyx thick, about half the length, cam- 

 panulate, the lower tooth much larger than the others and about
