MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



A climl)ing plant, with opposite, petioled, iiiolloiis foliage, a pair 

 of glands at the summit of the petioles, on the npper side. Plow- 

 ers yellow, slenderly pedicelled, in lateral, short-peduncled 

 umbels. 



Apparently related to Hiraea, but differing in its glandular 

 petioles, its distinct pistils, without crests, and its peculiar an- 

 thers, which approach Pterandra by their thin margin, though 

 scarcely to be called winged. 



Jubistylis mollis 



Softly, though not very densely pilose, with white hairs. 

 Stems twining, brown, terete or irregularly angled. Branch- 

 lets short, slender, leafy, the younger portions pilose with coarse 

 white divaricate or often reflexed hairs. Petioles of the larger 

 leaves 2 cm. long, slender, densely pilose, bearing a pair of 

 lilackish glands at the summit, on the upper side. Blades to 1 

 dm. long and half as wide, ovate with rounded base and shortly 

 acuminate and acutish summit, entire, thin, the upper surface 

 dark-green with a slight gray appearance from a sparse covering 

 of gray hairs, the lower surface densely pilose and gray, the 

 venation slightly prominent beneath, the secondaries about 8 on 

 each side, strongly ascending. Umbels loosely few-flowered, 

 short-peduncled, the pedicels filiform but rigid, about 1.5 cm. 

 long. Sej)als 3 mm. long and broad, ovate, obtuse, thin, pilose, 

 glandless. Unguis of petals longer than the sepals, stout, the 

 lamina abrupt, 5 mm. broad and not quite so long, yellow, the 

 margin crenate. Stamens unequal, the longest nearly twice the 

 lengih of the sepals, the anthers short, ovate, obtuse. Pistils 3, 

 densely and coarsely long-pilose, the styles about as long as 

 the stamens. 



Collected along the cataracts of the Bopi River, 3,000 feet, 

 H. H. Rushy, September 6, 1921 (no. 732). ''A large vine in the 

 edge of the forest." 



Banisteriopsis Whitei 



Grayish-pubescent throughout, the bright-green upper leaf- 

 surfaces sparsely so. Branchlets elongate, slender, terete, 

 sparsely leafy, the leaves opposite, glandular, the stipules not 

 apparent. Petioles 4 to 8 mm. long, very slender, the blades 

 2 to 4 cm. long and 1 to 2 cm. wide, ovate, with blunt or rounded 

 base and obtuse or acutish summit, entire, thin, softly pubescent 

 beneath and less so above, the venation inconsijicuous. Flowers
