MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



SiMARUBACEAE 

 Picramnia monninaefolia 



(Friiitino: specimen.) Densely and softly pubescent, except 

 the upper leaf-surfaces, which are sparingly pubescent on the 

 principal veins. Branches terete, slender. Leaves 1 to 2 dm. 

 long, the petiole mostly about a sixth or less of the total length. 

 Leaflets mostly 9 or 11, sul:)opposite, the petiolules about 2 imn. 

 long, the blades 3 to 7 cm. long, 1.5 to 3.5 cm. broad, the lower 

 successively smaller, ovate, mostly rounded at the base, especi- 

 ally the lower ones, abruptly short-pointed and acutish, entire, 

 thickish, but herbaceous, the slender venation little prominent 

 on the lower surface, the secondaries about 6 on each side, 

 slightly falcate, connecting at some distance from the margin, 

 the remaining venation obscure. Raceme elongated slender, 

 long-petioled, the pedicels slender, spreading or recurved, about 

 7 mm. long, slightly thickened upward. Fruiting calyx about 4 

 mm. broad, 5-parted nearly to the base, the ovate acute lobes 

 widely spreading. Fruit about 1 cm. long and two thirds as 

 wide, ellipsoid, black, glabrous or sparingly pubescent, bearing 

 two short style-bases. 



A single specimen probably collected near Canamina, but col- 

 lection data wanting {no. 434 A). Species near P. Spruceana. 



BURSEEACEAE 



Icica rhynchophylla 



Glabrous, the branchlets slender, lightly sulcate. Petioles 7 

 cm. or more long, the rachis about twice as long, slender, terete. 

 Leaflets mostly 7, the lowermost about half the size of the upper- 

 most, the slender petiolules about 3 cm. long, the upper portion 

 winged by an involute extension of the blade about 5 mm. long. 

 Blades of the leaflets 10 to 20 cm. long, 4 to 8 cm. broad, oval, 

 obtusish at both ends, bearing a very abrupt narrow appendage 

 about one seventh of the length of the blade, which is entire, 

 thin and dark-green, the slender venation lightly prominent 

 above, sharply so beneath, the secondaries about 12 on each side, 

 widely spreading, the outer ends abruptly up-curved, and con- 

 necting near the margin, their branches meeting midway at a 

 broad angle, the venation loosely anastomosing. Spikes loosely 

 paniculately branched, shortly pedunculate, about half the length 

 of their leaves, mostly loosely flowered. Flowers 5-merous, the 

 buds immature in my specimen. Fruit ovoid, 2 cm. long and
