Principles of Classification, 'H 
Baked and deposited in the bottom of the calyx ; and 
in the common dandelion, and many plants of the same 
kind, the seeds are attached to the receptacle without 
any covering. 
Various kinds of seed-vessels are described. The cap- 
sule, which is of a leathei’y or membranous texture, is 
composed of one or several cells, as in campanula and 
poppy. The follicle is a seed-vessel of one valve and 
one cell, bursting lengthwise, and bearing the seeds 
near its edges, as in periwinkle and pseony. The sili- 
que, siliqua, is a long dry seed-vessel of two valves, as 
in stock jilly-flower. The silicic is a short round pod, 
as in vernal whitlow grass. The legume, legumcn, is a 
seed-vessel of two oblong valves, and is peculiar to the 
pea tribe. The tamarind produces a legume filled with 
pulp, in which the seeds are imbedded. The drupe, 
drupa, is the seed-vessel peculiar to stone fruit, has a 
fleshy coat, and contains a single hard and bony nut, 
as in the cherry, the plum, and the peach. The cocoa- 
nut also comes under the denomination of drupe. The 
pomum or apple has a fleshy coat, but includes a cap- 
sule, with several seeds, as in the common apple or pear. 
The berry, bacca, is fleshy, without valves, and con- 
tains one or more seeds, surrounded with pulp, as in 
deadly nightshade and ivy. The fruit of the raspberry 
and bramble is called a compound berry, and the sepa- 
rated parts are named acini, Strobilus or cone, is a 
catkin, hardened and enlarged into a seed vessel, exam- 
ples of which are found in the pine tribe, i 
The seeds are extremely various in form and size ; 
they are composed of the embryo or germ ; of cotyle- 
dons or seed-lobes ; the albumen or farinaceous part, 
the mtellus or yoke ; the testa, which contains the
