670 PHANEROGAMIA. 



into its very base, nearly hypogynous, distinct: filaments filiform, 

 about the length of the calyx : anthers didymous, incumbent, two- 

 celled, destitute of a connective ; the cells opening lengthwise. Pol- 

 len-grains globose, simple, not very abundant. Glands of the disk 

 hypogynous, as many as the stamens and alternate with them, scale- 

 like, cuneate or oblong, fleshy, truncate or emarginate, sometimes 

 slightly united ? Pistils as many as the segments of the calyx and 

 alternate with them, sparingly hairy, ovoid, entirely free and sepa- 

 rate, tapering into a persistent style, which is tipped by a capitate- 

 truncate stigma. Ovule solitary, affixed to the ventral suture near 

 the middle, pendulous, between amphitropous and anatropous. Folli- 

 cles one-seeded, almost glabrous, thrice the length of the persistent 

 calyx, compressed, semiovate, sometimes slightly lunate, pointed by 

 the style, coriaceo-cartilaginous in texture, a line and a half long, de- 

 hiscent down the ventral suture, from which a filiform edge often 

 separates. Seed winged at the apex (the micropylar end), filling the 

 cell, oblong, compressed, the thin and membranaceous testa not reticu- 

 lated, below conformed to the oval nucleus, not at all produced at the 

 base or chalaza, above extended into the thin and obscurely reticu- 

 lated wing. Embryo straight, in the axis of rather copious fleshy 

 albumen, occupying the greater part of its length, somewhat cylin- 

 drical, but the oblong cotyledons a little broader and flattened, and 

 about half the length of the superior radicle.
