2. O. myristicifolia, Oliv. Branches terete, soon glabrous. Leaves 

 rather coriaceous, acute or acujninate, rounded or obtuse at the base, glabrous 

 and smooth above, obsoletely pubescent glabrescent beneath ; midrib and 

 lateral nerves prominent, venation obscure; 8-10 in. long, 2|~3 in. broad; 

 ])etiole 4-6 lines. Pedicels 1 or 2, erect, nearly 1 in. long, puberulous, on 

 very short axillary shoots or peduncles, 2-4 lines long. Sepals broadly ovate 

 below, abruptly acuminate. Outer petals "bright yellow," coriaceous, sub- 

 acute, sparsely pubescent outside, f-1 in. long in our specimen, but perhaps 

 not fully grown ; inner petals thick, concave below, thickened and trigonous 

 above, 5-6 lines long. Anthers elongate, narrowly linear; connective

 tapering into slender subulate styles ; ovules solitary, erect. Fruit unknown.

 Outer petals spreading, rather acute, in our specimens about \ in. long, but 

 probably not developed ; inner petals connivent, about half as h)ng. Anthers
