New Species of South American Plants 35 



leaflets 7, the lowest pair smaller, the larger 15 cm. long, 6 cm. 

 broad, oblong-oblanceolate, with the base abruptly contracted 

 into the very short petiolule and with a very abrupt acutish 

 terminal point 10 or 12 mm. long; thin, deep-green, the slender 

 venation prominent beneath and slightly so above, the prin- 

 cipal secondaries about 15 on each side, lightly falcate and 

 little ascending, anastomosing near the margin, the venation 

 rather coarsely reticulate. Inflorescence leaves similar, the 

 leaflets about i dm. long and narrower than those of the foliage 

 leaves. Panicles crowded at the ends of the branchlets, the 

 long stout peduncles sharply angled and striate, much branched 

 above, the ultimate branchlets crowded at the summit and 

 densely flowered at their summits. Bracts very small, ovate, 

 acute, thick. Flowers sessile, the calyx i mm. long and 2 mm. 

 broad, thick, lobed nearly half way, the lobes nearly semi-circu- 

 lar, with a minute point at the summit. Petals 3 mm. long, 

 ovate, obtuse. Stamens 8, 2 mm. long, equalling the pistil, the 

 filaments very short. Ovary short-conical. Disk with 8 ob- 

 tuse protuberences. 



"A tree to 50 feet, in damp, low forest near the coast. Flow- 

 ers whitish. Don Diego, May 21," (H. H. Smith, Colombia, 

 No. 2743.) 



Protium Orinocense. 



Glabrous, the branchlets stout, terete. Petioles 2 to 4 cm. 

 long, stout, sub-terete, attached by a broad base. Leaf tri- 

 foliolate. Petiolules of the lateral leaflets i to 1.5 cm. long, 

 stout, the blades 10 to 15 cm. long, 4 to 6 cm. broad, lance- 

 oblong with inequilateral, blunt base and abruptly short- 

 acuminate and obtuse summit, thick and coriaceous, deep-green, 

 the slender venation prominent on both sides, the principal 

 secondaries 10 or 12 on each side, nearly divaricate, the outer 

 portion falcate and inter-arching near the margin, the slender 

 venation strongly and rather finely anastomosing. Petiolule 

 of the terminal leaflet 3 or 4 cm. long, the blade similar to the 

 lateral, but nearly a half larger. Panicle terminal, sub-sessile, 

 the branches erect, stoutly peduncled, loosely branched. Flow- 

 ers crowded at the ends of the branchlets, minutely bracted, 

 very shortly and stoutly pedicelled, the pedicels minutely white- 

 pilose at the base. Calyx 2 or 3 mm. broad, the lobes very 

 broadly ovate, acute, spreading. Corolla about twice the 

 length of the calyx. 



Near Santa Catalina, lower Orinoco, Venezuela, May 1896. 

 (Rusby and Squires, No. 133.) 



Another specimen from the same region, without number, 

 may be a distinct species. Some of its leaves are 5-foliolate,
