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



yellowish-green, and somewhat shining, beneath silvery with a fine close indu- 

 ment. Peduncle slender, erect, 8-15 cm. long, bearing a terminal glomerule of 

 4-8 sessile 4-merous flowers and sometimes a smaller subterminal 4-flowered 

 glomerule. Hypanthium cup-shaped, 5«4 mm. long, very thinly gray-tomentulose. 

 Calyx in bud conic, blunt, about as long as the hypanthium and with similar in- 

 dument, circumscissile about 2.6 mm. from the torus. Petals rotund-obovate, 10 

 mm. long, 11 mm. wide. Stamens isomorphic; filaments 3.6-4.2 mm. long; anthers 

 slightly arcuate, subulate, 6.6-6.9 mm. long; spur conic, 0.2 mm. long. Ovary 

 superior, apparently 2-celled, glabrous except for a few minute delicate hairs 

 at the summit; style 11 mm. long; stigma punctiform. 



TYPE: from savannas at the summit of Cerro Sipapo, Bassett Maguire & 

 Louis Politi 28669; New York Botanical Garden. Paratypes: Maguire & Politi 

 numbers 27365, 27522, and 27932. 



Graffenrieda versicolor Gl., sp. nov. 



Frutex cauli crasso tenuiter tomentuloso; folia petiolata, lanceolata vel el- 

 liptica, coriacea, utrinque obtusa, 1-nervia, supra glabra, subtus tenuiter tomen- 

 tosa brunnea vel argentea; panicula elongata; flores 5-meri breviter pedicellati; 

 hypanthio obconico; calyx calyptratus, ad anthesin irregulariter ad torum ruptus; 

 petala triangulari-obovata; antherae subulatae arcuatae; calcar breve conicum; 

 ovarium summo 10-aristatum. 



Sparingly branched shrub, the thick stems, petioles, lower leaf-surface, 

 panicle, and hypanthium densely but very thinly tomentulose. Petioles stout, 

 1-1.5 cnio long. Blades coriaceous, lanceolate to elliptic, up to 9.5 by 3 cm., 

 obtuse at both ends, 1-nerved, entire, glabrous above. Panicle terminal, pedun- 

 cled; flowers 5-merous, on stout pedicels 1-2 mm. long, in terminal glomerules 

 and also in a few axillary short-stalked glomerules. Hypanthium narrowly ob- 

 conic, 5 mm. long, thick-walled; calyx calyptrate, at anthesis irregularly rup- 

 tured to the torus into more or less ovate-triangular lobes up to 4 mm. long. 

 Petals broadly triangular-obovate, 9 mm. long, 8 mm. wide. Stamens isomorphic; 

 filaments flattened, 4-4.7 mm. long; anthers arcuate, subulate, about 6.5 mm. 

 long; spur conic, erect, 1.25 mm. long. Ovary superior, narrowly conic, prolonged 

 around the style-base into 10 erect subulate awns. 



TYPE: from savannas on the summit of Cerro Sipapo, Bassett Maguire & Louis 

 Politi 27948- A; New York Botanical Garden. Paratypes: Maguire & Politi 27531 

 and £7948; the latter has leaves up to 12 cm. long and 6 cm. wide and panicles 

 as much as 2 dm. long. 



At least three other species of Graffenrieda were collected without flowers 

 and could not be identified from foliage with any species known from the region. 

 Their 27879, from intermediate altitudes on Cerro Sipapo, is a tree with very 

 large ovate-lanceolate leaves densely brown-tomentose beneath and a large 

 panicle with widely diverging branches. Maguire & Politi 27936 and 27576 repre- 

 sent a small tree with very large elliptic leaves glabrous beneath and a huge, 

 widely branched panicle; it closely resembles G. boliviensis Cogn. in foliage and 

 habit. Maguire & Politi 28272 and 28478a are from trees at intermediate eleva- 

 tions and summit of Cerro Sipapo with broadly ovate, strongly 9-pli-nerved leaves; 

 the calyx apparently ruptures irregularly and the persistent lobes become in- 

 durate in fruit. 



Salpinga secunda Schr. & Mart*. 



Flowers white, infrequent in lowland forests south of Culebra, north end of 

 Cerro Duida, Maguire & Maguire 29149; an Amazonian species.
