within along margins and apically, black-punctate in lines; stamens about 
3 mm. long; filaments stout, 1.5-1.8 mm. long; anthers erect, narrowly lanceo-

45858 (F, type; G, LL, UC, US, isotypes), shrub 20 ft. tall, leaves deep green above, paler 
green beneath, pedicels recurved, rose-colored. Peren: San Luis, km. 52 of road, in rain forest, 
July 10, 1959, C. L. Lundell 16269A (LL), arborescent shrub, 10 ft. high, inflorescence and 
flowers red; Dolores, on Rio Mopan trail, 4 km. east of village, in high forest, May 28, 1961, 
Elias Contreras 2403 (LL), small tree, 10 ft. high, flowers carmine; Dolores, bordering Rio 
Ixcol, 1 km. east of village, in high forest, June 3, 1961, Elias Contreras 2408 (LL), small tree, 
2 in. diam., 10 ft. high, flowers reddish. 
The leaves of Contreras 2403 are obovate and superficially resemble those of 
P. membranacea Lundell, but the reddish indument of P. oblanceolata makes 
possible the immediate recognition of this taxon.
