HELICIA INTEGRA sp. nov. 
Arbor parva, glabra; foliis oblongo-lanceolatis vel oblongo- 
oblanceolatis, usque ad 14 cm longis, integerrimis, utrinque an- 
gustatis, apice acuminatis, basi cuneatis, brevissime petiolatis, 
chartaceis vel subcoriaceis ; racemis folia subaequantibus, mul- 
tifloris, axillaribus ; floribus tenuibus, circiter 1.5 cm longis. 
A small glabrous tree, or the racemes with very few, scattered, 
deciduous hairs. Branches terete, grayish-brown, smooth. 
Leaves oblong-lanceolate to oblong-oblanceolate, entire, 10 to 14 
cm long, 2 to 5 cm wide, chartaceous or subcoriaceous, somewhat 
yellowish when dry, slightly shining, glabrous, narrowed at 
both ends, the apex shortly and usually sharply acuminate or 
acute, the base cuneate, narrowed into the very short petiole; 
lateral nerves 10 to 12 pairs, slender, distinct, the reticulations

solitary, axillary, about as long as the leaves, many-flowered. 
Flowers yellowish, in pairs, their pedicels in pairs, free to the
