14. TREWIA Linn. 



1. Trewia ambigua INIerrill, sp. nov. 



A tree 8 to 12 m. high with penninerved leaves, axillary and terminal inflores- 

 cence and 1 -celled fruits. Dioecious. Branches brown, glabrous, the younger 

 branchlets finely brownish puberulent. Leaves opposite, ovate to lanceolate ovate, 

 ehartaceous, glabrous throughout or bearded in the vein axils beneath, 10 to 

 20 cm. long, 4. .5 to 9.5 cm. wide, dull or slightly shining, the apex short or 

 rather long acuminate, the base acute, the margins subentire to obscurely coarsely 

 undulate or crenate undvilate, often with few scattered glands; nerves 8 to 9 on 

 each side of the midrib, prominent beneath; petioles 1.5 to 6 cm. long, somewhat 

 pubescent. Male inflorescence axillary, racemose, 5 to 8 cm. long, densely bro\vnish 

 puberulent, the flowers solitary or 3 to 6 in the axil of the same bract, the buds 

 globose, sessile or short pedicelled. Sepals 4, ovate to oblong ovate, acute, about 3 

 mm. long, pubescent outside. Stamens indefinite; filaments glabrous, about 1.3 

 mm. long; anthers 2-celled, about 0.3 mm. long. Female inflorescence axillary, race- 

 mose, 4 to 7 cm. long, long peduncled, pubescent, few flowered, the pedicels about 

 2 mm. long, one flower in each bract, the bracts ovate, decidous. Ovary oblong

Differing from Treioia in its 1-celled, 1-ovuled ovaries and 1-celled, 1-seeded 

 fruits, and in its penninerved leaves, but apparently referable to the genus.
