New Species of South American Plants 83 



acuminate and obtuse at each end, coriaceous, entire, deep- 

 green and with the very slender venation lightly prominent on 

 both surfaces, the midrib sharply impressed above. Principal 

 veins about 17 on each side, nearly straight, widely spreading. 

 Panicle small, broad, densely flowered, shortly and stoutly 

 peduncled, subulate-bracted. Sepals distinct, 2 mm. long and 

 broad, ovate, blunt, thickish, the disk annular, coatinuous, 

 broad and entire. Corolla tube 3 cm. long, extremely slender, 

 more so below, the limb nearly 3 cm. broad, its lobes obovate- 

 spatulafe with narrowed base. Collected by H. H. Rusby at 

 Bolivar, Venezuela, April, 1896, without numbsr. The same 

 collected by Stevens. 



Tabernaemontana albescens. 



Glabrous, with the leaves glaucous beneath. Brancnes 

 slender, pale-green, the branchlets, more or less quadrangular. 

 Petioles 5 or 6 mm. long, broad, channeled above and connate. 

 Blades 10 to 25 cm. long, 3 to 8 cm. broad, lance-oblong, with 

 the base abruptly produced into the petiole, and abruptly short- 

 pointed and acutish summit, deep-green above, very pale or whitish 

 underneath, especially along the course of the secondaries, 

 which are 18 to 20 on each side, with some additional fainter 

 ones, very slender, sharply prominent beneath, spreading widely 

 and falcately and connecting near the margin. Peduncle about as 

 long as the petiole, stout, brown, few-flowered, the pedicels 

 5 or 6 mm. long, sharply angled above, about twice the length 

 of the ovate, acute thickish bracts. Calyx campanulate, 6 or 

 7 mm. long, lobed more than halfway, the lobes obovate with 

 rounded summit. Corolla-tube nearly 2.5 cm. long, 2 mm. 

 thick, slightly dilated at the summit, the limb 4 cm. broad. 

 Anthers just below the throat of the corolla, 6 mm. long. 



Santa Catalina, Lower Orinoco, Venezuela, May, 1896, 

 (Rusby and Squires No. 300.) 



Tabernaemontana cuspidata. 



Glabrous. Branchlets quadrangular, very slender, the inter- 

 nodes longer than the leaves. Leaves about 15 cm. long by 

 5-7 cm. broad, oblanceolate, abruptly contracted at the base 

 into a very short broad petiole and at the summit into a short 

 and narrow obtuse point. Panicles small and few-flowered, 

 the peduncles about 4 cm. long, the pedicels very slender, 15 

 mm. long. Calyx lobed nearly to the base, the lobes finely- 

 many-nerved, 5 mm. long and nearly as broad, with regularly 

 rounded summit, very thick and tough. Corolla tube 18 mm. 

 long, rather stout, thelobes6-8mm. long, broadly ovate, obtuse. 

 Glands of the calyx lobes originating slightly above the base, 

 3 on each lobe, yellow, mostly 2-parted. Glands of the disk 

 blackish. Ovaries stout, more than half the length of the 

 calyx.
