produced above the seed-cavity iuto a much elongate leathery wing 

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

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

 Polynesian. 



The differences between the genera Smythea and Veiitilago He entirely in the . 

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

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

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

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

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

 extent, from below upw.'irds and along the mesial line, into two pieces. In Veiiti- 

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

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

 of fibro-vascnlar bundles.
