Fruit and Seed. The ovary is inferior, crowned by a disc, 

 and from one- to ten-celled. The ovules are numerous, twin, 

 or solitary in each cell, and inserted on, or immersed in the 

 placentas, or concave and surrounding them as in Galium, 

 erect, ascending, horizontal, or pendulous, anatropous, semi- 

 anatropous or arnphitropous. The fruit is baccate, drupaceous, 

 capsular or consists of dehiscent or indehiscent cocci, and 

 varies with from two to ten, very rarely one cell. The seed 

 varies greatly in size, and is immersed in the receptacle, or in 

 pulp, or is quite free with a membranous, leathery, crustaceous 

 or very rarely woody testa ; it is however sometimes winged or 

 appendiculate. Endosperm is usually copious, fleshy or horny, 

 very rarely reduced to a thin layer or entirely wanting ; it is 

 either solid or ruminated. The embryo varies greatly in size, 

 and is curved, straight or clavate. The cotyledons are flat, 

 or semiterete, ovate or cordate, foliaceous, with a terete or 

 clavate, superior or inferior radicle. 



There are several distinct types of seeds in the Order. 

 Exalbuminous seeds occur in species of Henriquezia, Platy- 

 carpum, and several of the tribe Guettardese. Kuminated 

 seeds are met with in Coptosperma, Galiniera, Eutidea, Poly- 

 spheeria, and in species of Psychotrieae.
