40 New Species of South American Plants 



6 on each side, strongly ascending, lightly curved, connected 

 by numerous crooked tertiaries and these by very numerous 

 others. Racemes axillary, much shorter than their leaves, 

 slender, short-peduncled or sub-sessile, rather loosely flowered, 

 the bracts at the base of the pedicels 1.5 to 2 mm. long, recurved, 

 ovate, obtuse. Pedicels 5 mm. long, very slender, erect or 

 spreading, 2-bracteolate at about the middle, the bractlets 

 half as long as the pedicel and nearly as broad as long, obovate 

 with rounded summit, faintly puberulent, brown or purple, 

 thickish. Calyx 5 mm. broad, lo-glandular, the glands large. 

 Petals 6 mm. long, the claw short, spreading, the limb obovate, 

 lightly concave, fimbriate, strongly carinate. Stamens half as 

 long as the petals, the filaments lightly connate below, slightly 

 pilose. Styles stout, straight about equaling the stamens, the 

 stigma truncate, the ovary densely pilose. Fruit very young, 

 the wings linear-oblanceolate with rounded summit, the dorsal 

 crest deeply lobed, the tuberculate body of the fruit bearing a 

 narrow appendage in the center of each side. 



"A twining vine, to 20 or 25 feet, rare in damp forest, 500 

 to 2,000 feet, January to May. Specimens from Don Amo 

 road, 500 feet, February i." (Herbert H. Smith, Colombia, 

 No. 1511.) 



No. 1527 from Jordan, 800 feet, February 22, the "petals 

 yellow", is the same. 



Securidaca Orinocensis. 



Branchlets, entire inflorescence, veins of the lower leaf- 

 surfaces and of the body of fruit gray-puberulent and slightly 

 ferruginous. Flowering branchlets recurved, terete, nodose, 

 leafy, the internodes unequal, the leaves very shortly stout- 

 petioled. Blades thickish, 2-7 cm. long, broadly ovate, slightly 

 cordate, the summit blunt or rounded, the margin sub-entire, 

 very thinly revolute, the midrib slender and sharp underneath, 

 lightly impressed above, the principal veins slender, about 8 

 pairs with fainter ones alternating, strongly upcurved and 

 lightly anastomosing near the margin. Glands blackish, at- 

 tached to lowest vein near the midrib. Racemes terminal, re- 

 curved, naked, the lower portion strongly nodose from the 

 fallen flowers. Pedicels stoutish, about 3 mm. long. Flowers 

 2 cm. long. Lowest sepal 5 mm. long, obtuse, saccate, finely 

 nerved, the lateral about two-thirds as long, broadly ovate, 

 with rounded summit, the wing-sepals 12-15 mm. long, 6-8 

 mm. broad, the body ovate, obtuse, the lower third cuneate. 

 Wing-petals 12 mm. long, 2.5 mm. wide, obliquely oblanceolate 

 with rounded summit, and darker base. Keel 13 mm. long, 

 not including the narrow claw, nearly as wide, erect, lightly 

 3-lobed, the middle lobe short and broad, strongly appendaged
