New Species of South American Plants 29' 



about 12 cm. long, the rachis about a half longer, both very- 

 stout, nearly terete. Leaflets 5 or 6 pairs, imperfectly opposite^ 

 nearly sessile, the petiolules about as broad as long, shaiply 

 articulated with the midrib, the blades 10 to 15 cm. long, 7 to 

 8 cm. broad, the lower shorter and relatively broader, ellip- 

 tical with rounded or very slightly cordate base and very slightly 

 emarginate summit, entire, thick and coriaceous, the venation 

 impressed above, very prominent underneath, the principal 

 secondaries 9 or 10 on each side, very stout, coarsely connected 

 by the tertiaries. Racemes loosely and shortly paniculate from 

 the nodes, the small thick bracts ovate and acuminate. Only 

 buds seen, their pedicels short, stout, angled. Buds globose,, 

 about 6 mm. broad, the calyx thick and coriaceous. Petal one, 

 broadly ovate on a short stout claw, strongly nerved. Stamens 

 numerous, distinct, unequal in the bud. Pistil strongly curved. 

 Beni River shore, Bolivia, July 1886. (H. H. Rusby No. 

 978). 



Lotoxalis phaseolifolia. 



More or less puberulent throughout. Stems shrubby, tall. 

 Stipules apparently deciduous, not seen.. Petioles 6 to '15 cm. 

 long, very slender, sulcate. Leaflets 3, the lateral on stout 

 petiolules 2 mm. long, the blades 5 to 7 cm. long, 2 to 3.5 cm. 

 broad, inequilaterally ovate, with blunt or rounded base and 

 acuminate and acute summit, very thin, bright-green, sparsely 

 short-pilose on both sides, the venation scarcely prominent, 

 the secondaries 5 to 7 on each side, besides one that forms the 

 upper margin near the base. Rachis 12 to 25 mm. long, its 

 middle leaflet similar to the lateral, but somewhat larger and 

 equilateral, the base more or less acute. The dimensions of the 

 leaflets on another sheet, apparently the basal portion of the 

 same plant, are fully a half greater than those here given. 

 Peduncles 10 to i8 cm. long, very slender, sub-erect, the summit 

 bifid, the recurved-spreading branches short, closely beset 

 with the short bases of the fallen flowers, subtended by minute, 

 subulate bractlets. Pedicels 3 to 5 mm. long, filiform, a little 

 thicker at the summit. Sepals i cm. long, lanceolate, acumin- 

 ate, and acute, finely nerved. Dissecting material wanting. 

 Capsule 6 mm. long, broadly ellipsoidal, short-stipitate, the 

 stipe broader than long, ribbed, the pod bearing 5 short, stout, 

 distinct styles, and enclosed by the persistent calyx. Seed 

 nearly as long as the pod, ovoid, short-beaked, strongly muri- 

 cate, slightly curved. 



"A shrub of 1.5 meters, at Antaheracana near Cochabamba, 

 Bolivia, 750 meters altitude, June 1909." (Otto Buchtien> 

 No. 2232.)
