 stout-pedicelled, partly immersed in the deep hypanthium.

 Androeeium of numerous monadelphous or grouped stamens, or few in 

 Buettneriaceae. Gynoecium of several distinct or united carpels. Fruit 

 capsular, follicular, berry-like, or nut-like.

 as many as the sepals. Gynoecium of 2-several united carpels. Fruit 

 capsular, nut-like, or berry-like.

 and accompanied by staminodia. Anther-sacs separated. Berry 1-2-seeded. 

 — Late spr. and sum. — Basswood. Linn. Lime-tree, Bee-tree.
