produced above the seed-cavity into a much, elongate leathery wing, 

 1-celled, ] seeded, dehiscing vertically into 2 valves. Seed solitary, 

 large, compressed, exalbuminous. — Distrib. Four species, Malayan and 

 Polynesian. 



The differences between the genera Smythea and Ventilago lie entirely in the 

 fruit. Both have 2-celled ovaries with two styles, and in both only one ovale 

 becomes a seed. In both the epicarp of the frait is prolonged above the apex of 

 the seed-chamber into a long coriaceous wing with a vertical midrib. In Ventilago 

 the fruit never dehisces, and the wing never divides. In Smythea the seed-cham- 

 ber dehisces vertically along its dissepiment, and the wing separates to some 

 extent, from below upwards and along the mesial line, into two pieces. In Venti- 

 lago the mesial line has the appearance of the midrib of a leaf, being quite single : 

 in Smythea the mesial line consists, in its lower part at least, of two parallel sets 

 of fibro-vascular bundles.

Distinguished by its entire perfectly glabrous very reticulate 

 leaves, glabrous petiole, hairy ovary, and lanceolate acuminate fruit. 



2. Smythea macrocarpa, Hemsley in Hook. Ic. PI. t. L558. Young 

 branches slender, rufous-puberulous. Leaves oblong-oblanceolate to 

 obovate-elliptic, acuminate, serrate, narrowed to the slightly oblique 

 base ; both surfaces glabrous ; main nerves 6 to 9 pairs, slightly 

 curved, ascending; length 25 to 5 or even 7 in., breadth 1 to 1*5 or 

 even 2 in. ; petiole "1 to "2 in. or none. Fascicles about 10-flowered ; 

 the flowers "15 in. in diam., pedicellate. Calyx sparsely pubescent 

 outside, glabrous inside ; its 5 lobes triangular, thick. Disc glabrous, 

 neither lobed nor pitted. Ovary glabrous. Fruit leathery, oblono-,
