72 TILIACE2E. (LINDEN FAMILY.) 
somewhat heart-shaped and lobed cotyledons, which are a little 
folded.—Fine trees, with soft and white wood, obliquely heart- 
shaped and serrate leaves, deciduous stipules, and small cymes of 
flowers, hanging on an axillary peduncle which is united to a leaf¬ 
like bract. Flowers cream-color, honey-bearing, fragrant. (The 
classical name of the genus.) 
1. T. Americana, L. (Basswood.) Leaves green and 
glabrous or nearly so. — Rich woods. June. — This familiar tree is 
rarely called Lime-tree , oftener White-wood , commonly Basswood;

T. EuropA:a, the European Linden, which is planted in and 
near our cities as an ornamental tree, is at once distinguished from 
any native species by the absence of the petal-like scales among the 
stamens. This tree (the Lin ) gave the family name to Linnccus. 
Order 24. LINACEiE. (Flax Family.) 
Herbs , with regular hypogynous flowers 4 — 5 -merous 
throughout , strongly imbricated calyx and convolute petals, 
the 5 stamens monadelphous at the base, and an 8- 10 -seed-

there are styles ; — consisting chiefly of the genus 
*• L. Flax. 
Sepals, petals, stamens, and styles 5. Pod of 5 united carpels 
(into which it splits in dehiscence) and only 5-celled, with 2 seeds 
hanging from the summit of each ; but each cell is incompletely 
or completely divided into two by a false partition which projects 
trom the back of the carpels, thus becoming 10-celled. Seeds 
anatropous, mucilaginous, flattened, containing a large embryo 
wu pl,.no-convex cotyledons-Herbs, with a fibrous bark, sim¬ 
ple and sessile entire leaves (alternate or often opposite) without
