Heteropterys. 381 



seen. Petioles about 7 mm long, narrowly margined, the margins involute, sulcate 

 beneath, like the lower portion of the midrib. Blades 1 — 1,5 dm long, 2,5 — 4 cm 

 broad, regularly acuminate and acute, acutish at the base, entire, thick, lustrous above, 

 pale and slightly sericeous beneath, the slender venation not prominent, the principal 

 secondaries 10 or 4 2 on each side. Panicle large, lax, the branches opposite from 

 a somewhat turgid node, the branches and branchlets subtended by small reduced 

 leaves, the pedicels subtended by ovate, acuminate and acute, green, thick bracts. 

 Pedicels stoutish, about 3 mm long, the flowers deep-yellow. Calyx 8-glandular, the 

 sepals nearly 3 mm long, 2 mm wide, ovate, blunt, thick, green, erect. Petals 7 mm 

 long, the claw about a fourth of this length, and nearly equally broad, concave, dentate, 

 the teeth short-fimbriate. Filaments subulate, fleshy, monadelphous at the base, un- 

 equal, the longest equalling the styles. Anthers 8, reflexed, the oblong greenish thecae 

 borne on the face of a large, subglobular, black, gland-like connective. Ovary black, 

 deeply 3-lobed, lightly pubescent, the styles stout, spreading, truncate. Fruit not seen. 



Dr. Gleason says: Bears a strong general resemblance to B. Mathewsiana (A. Juss.), 

 but in that species the calyx appears glandless.
