Liriodendron tulipiferum, L. Yellow Poplar. Tulip-Tree. 
The most beautiful of our trees, attaining its highest perfection 
of growth in the Mississippi bottoms, where specimens have 
occurred attaining an altitude of about 200° by 8-9° diam- 
eter 6 feet above ground. The bark of young trees, which 
alone is used for medicinal preparations, is smooth and gray, 
but in old trees it forms a reticulation of prominent ridges 
with deeply depressed intervals. The leaves are smooth, 
bright green, truncate and four-lobed, and provided with 
large, opposite flat stipules, which serve the function of scales 
to the young buds, ultimately deciduous. The flowers are 
large, of size and shape of a tulip ; they have a calyx of three 
deciduous segments, which are turned down, and a corolla 
of six erect petals forming a cup. Both sepals and petals 
are greenish, variegated with yellow and orange. The cone 
of fruit of the tulip-tree is 3' long, and does not split when 
ripe, as those of the magnolia do.
