MEMOIRS OF THE NEW 



YORK BOTANICAL GARDEN 



the surface. Style exserted, upwardly thickened, shortly two- 

 lobed, the stigmas rounded. Disk tumid, heiuispheric hut the 

 summit concave. Type, Flexantliera siihcordata Rusl)y. 



A tree, with opposite, ovate, ample leaves, and small terminal 

 panicles. A single imperfect capsule is two-celled, oblong, com- 

 pressed and with thick pericarp. Stipules not seen. The genus 

 is allied to Rustia, from which it differs in its smaller flowers, 

 reflexed and recurved dehiscent anthers and deciduous calyx- 

 limb and in the character of its placentae. 



Flexanthera subcordata 



Glabrous, the branchlets terete and stout. I'etioles 1 to 2 cm. 

 long, stout, subterete, the blades 10 to 25 cm. long, 6 to 18 cm. 

 broad, ovate and somewhat rhomboid, the base lightly cordate, 

 the summit short-acmninate and acute ; membranaceous, deep- 

 green on both sides, Avith the slender venation strongly promi- 

 nent underneath. Secondaries 15 to 20 on a side, widely spread- 

 ing, and falcately connecting near the margin. Panicles termi- 

 nal, solitary, (in one case two), five to seven cm. long inclusive 

 of the short, stout peduncle, loosely flowered, the flowers sessile 

 or the ovary tapering into a very short pedicel. Calyx 4 mm. 

 long, the lobes half as long as the tube and broader than long, 

 with rounded summits. Corolla 6 mm. long, the lobes one fourth 

 of the length, at length somewhat spreading, their summits 

 lightly concave and slightly pu])escent. Filaments, when fully 

 extended, nearly twice the length of the corolla, attached about 

 the middle of the tube, pilose at the base, flattened, broadest at 

 about the middle and again liroadened at the point of attachment 

 to the antliers, which is just back of the sinus. Anthers about 

 as long as the corolla-lobe, linear-oblong, at length reflexed and 

 recurved. Style equaling or exceeding the filaments, thickened 

 upward, shortly two-lobed, the stigmas rounded. 



East of Bonda, Colombia, in the month of July, Herbert H. 

 Smifh {no. 3404). "A tree to 40 feet in height." 



Mr. Smith regards this as distinct from his no. 92, by virtue 

 of its longer stamens. Further information in regard to this is 

 necessary. The filaments appear to elongate irregularly during 

 anthesis, and it is possible that a dimorphic condition may exist. 



Flexanthera fragrans 



Peduncles and inflorescence i)uberul('nt, tlie l)ranchlets rather 

 stout, leafy. Stipules deciduous, not seen. Petioles about 8 mm.
