MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



ascending,', often recurved toward the summit, strongly sulcate, 

 deep-pui'i^le. Petioles 1 to 2 cm. long, 2 or 3 times as long as the 

 rachis and, like it, narrowly winged, with the wing puberulent 

 and involute on drying, the leaflets 5, sessile, more or less pen- 

 dulous, the four lateral sube((ual, the terminal a little larger, 

 from 2.5 to 5 cm. long, l.f) to 3 cm. wide, oval with rounded 

 base (the terminal acutish), and obtusish summit, all nearly 

 equilateral, with 3 strong obtuse teeth above the middle, thick, 

 glabrous and sublucid, the midrib and secondaries impressed 

 above, strongly prominent beneath, the latter about 8 on a side, 

 stout, ascending, rather crooked, the intervening venation 

 densely and strongly anastomosing. Panicles racemiform, 1 to 

 1.5 dm. long, including the ])eduncle, not more than 1 cm. broad, 

 densely flowered, the branchlets mostly 2- to 4-flowered, the pedi- 

 cels very short, slender, the bracts setaceous, much longer than 

 the pedicels, the flowers, as pressed, 5 to 7 mm. broad. Fruit 

 about 18 mm. long, including the stipe, which is nearly a third 

 of the length, 1 cm. broad, pyriform, very shortly and stoutly 

 mucronate, and bearing a short connate style-base, the cells 

 empty in all my specimens.

Paullinia quercifolia 



Glabrous, the branchlets elongate, slender, heavily sulcate. 

 Leaves normally 5-foliolate, but the lowest pair of leaflets fre- 

 quently wanting and represented by a pair of blackish glandular 

 depressions. Petioles below these glands or leaflets 8 to 12 cm. 

 long, not margined, 5- to 7-costate. Rachis 5 to 7 cm. long, similar 

 to the petiole. Leaflets short-petioled, the lateral all sulx^qual, 

 12 to 20 cm. long, 6 to 8 cm. broad, oblanceolate, with short-acu- 

 minate base and very short obtuse terminal point, shallowly and 

 irregularly sinuate above the middle, thickish, lucid, the midrib 

 and secondaries lightly prominent above, sharply so beneath, the 

 latter about 12 on a side, slender, ascending at about 45 degrees, 

 straight! sh, abruptly upcurved at the end, to connect 3 or 4 

 mm. from the margin, the finer venation loosely reticulate. Ten- 

 drils wanting. Panicles racemiform, sessile or subsessile, about 

 1 dm. long, 1.5 cm. broad, the subtending bracts mostly linear, 

 ril)bed, densely floAvered, the branches mostly 5- to 7-flowered, the 

 bractlets minute, subulate, the flowers slenderly pedicelled, the 

 pedicels about as long as the flowers, recurved, the flowers 2 mm. 

 wide.
