MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [Vol. 8, No. 2 



Low tree, the vegetative parts except the upper surfaces of the leaflets mi- 

 nutely appressed-puberulent; leaves 7-1 1-foliolate, the petioles 2-4.5 err. long, 

 narrowly winged, the rachis canaliculate-margined above, 5-16 cm. long, the 

 petiolules 2-4 mm. long, transversely rugose; leaflets opposite or subopposite, 

 (4-)7-15 cm. long, (2-)3~5 cm. wide, lanceolate, oblong-lanceolate or elliptic, 

 the base obtuse or rotund, the apex acute to acuminate, the tip obtuse, the upper 

 surface glabrous, nitid, below glabrous or with very few scattered, minute, ap- 

 pressed hairlets, the primary veins barely prominulous above, below the reticula- 

 tion of the veins very distinct; inflorescences terminal, panicles of racemes, 7-11 

 cm. long, sparsely to densely appressed-puberulent, the bracteoles lanceolate, 

 1.5 mm. long, appressed-puberulent without but glabrous within, the pedicels 1-2 

 cm. long, articulate at the base of the flower; calyx-tube (3*)4-5 mm. long, 3.5-5 

 mm. wide at the apex, the lobes and tube sparsely appressed-puberulent without, 

 the sepals lance-ovate or ovate-triangular, 3-4 mm. long, 2.5 mm. wide, obtuse; 

 petals cucullate, oblong, 10-12 mm. long, 4.5—5 mm. .wide, glabrous except for the 

 ciliolate margin; stamens inflexed in bud, the filaments glabrous, 2.5 cm. long, 

 the anthers oval, about 2 mm. long, 1 mm. wide, villose-hirsutulous on dorsal 

 surface; pistil glabrous, sometimes abortive, the stigma expanded-truncate, the 

 style about 2 cm. long, the ovary linear-oblong, about 5 mm. long, 1.5 mm. wide, 

 6-10-ovulate, the stipe 4.0-4.5 mm. long; fruit irregularly oblong, acentric on the 

 stipe, 17-30 cm. long, 5-7.5 cm. wide, glabrous, the seed disciform, about 5.5 cm. 

 diameter, the testa reddish-brown, chartaceous. 



Specimens Examined: "Banks of the Essequibo," Scbomburgk 296 (type no. of C. 

 comosa Benth.; US); Demarara River, May 1887, Jenman 3915; Mazaruni River, August 

 1889, Jenman 5253; riverside, British Guiana, June 1924, Persaud 31; junction of Mazaruni 

 and Cuyuni Rivers, July 1924, E. H. Graham 251. 



This typical variety is in its larger flowers more closely associated with 

 variety laurifolia than with C. angustifolia, which it resembles in the glabrous 

 upper leaflet surface and in the shape of the sepals. Variety comosa is separable 

 from variety laurifolia on the glabrous condition of the leaflets already mentioned. 

 It has the narrowest range of all the taxa in the genus, being restricted to British 

 Guiana.

Tree to 40 m. tall, very similar to var. comosa but differing in having 7—13-

 long); filaments longer (3.5-4 cm. long); style longer (4-5 cm. long); stipe of the 

 ovary longer (7-10 mm. long).
