MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



cate or slightly cordate at the base, cuspidate, the cusp about 10 

 to 12 mm. long, o])tusish ; coriaceous, slightly lustrous above, 

 strongly 3-ribbed, with a pair of smaller ribs below, about 3 

 principal secondaries on each side of the midrib, the venation 

 slender, loosely reticulate, sharply prominent underneath, less 

 so above. Panicles very large, diffusely and loosely branched, 

 the very small flowers loosely racemed on the ultimate branch- 

 lets, subtended by rigid, acute, subulate, falcate bractlets, which 

 are longer than the very short pedicels. 



Staminate flowers nearly 1 mm. long, the bud obovoid, ob- 

 tuse. Sepals apparently 3, distinct, ovate, obtuse, longer than 

 the petals. Petals six, the outer aliout twice as large as the 

 inner, ovate with narrowed l)ase, the inner narrower. Stamens 

 united about two thirds of their length. 



Eurrenabaque, 1,000 feet, H. H. Riishij, October 19, 1921 {no. 

 1289). 



Pistillate plant collected in fruit at the same locality, October 

 6, 1921 {no. 796). The leaves are less coriaceous, more cordate 

 and less cuspidate. The panicle is small and long and slenderly 

 peduncled, the fruits sessile. Fruits oval, 1.5 cm. long, 1 cm. 

 broad, slightly inaequilateral, the style-scar terminal. Putamen 

 finely verrucose, flattened on one side, lightly ridged on the back, 

 the inside of the flattened side bearing a large hollow cylin- 

 draceous ridge which fits into the deep concavity of the flattened 

 side of the seed. 



I have little doulit that this plant pertains to an undescribed 

 genus. It has the habit and general appearance of Anomo- 

 spermum, but the floral structure excludes it from that genus. 

 Its structure most nearly aj^proaches that of Somplioxylon, but 

 is apparently distinct therefrom. The flowers are not in good 

 condition for study, and T have found it impossible to determine 

 the minuter details. 



x\nnonaceae 



Porcelia Saffordiana 



Twigs glabrous or minutely and closely puberulent, the flow- 

 ers grayish-tomentellate. Branchlets slender, enlarging greatly 

 in the fruiting stage. Petioles 5 to 10 mm. long, rather stout. 

 Blades to 15 cm. long by 5 cm. wide, lanceolate, with rounded.
