644 MONOECIA POLYANDRIA. Sagittaria, 
or even three come together, and are then surrounded by the 
same scaly calycle, or involucre to be mentioned under the 
next article. Calyx superior, its parts as in the male, with 
the base closely embraced on all sides by numerous hairy 
scales, The most exterior of which are broad; the inner 
ones are subulate points which become the capsule or spinous 
envelope of the seed. Filaments twelve, alternately shorter, 
the long ones six, about the length of the calyx. Anthers 
oval, two-lobed. Germ inferior, three-lobed, three-celled, 
with one ovulum in each, attached to the bottom of its cell, 
Styles three, a little recurved. Stigma simple, obtuse, Fruit 
from round to obovate, completely armed with ramous spines, 
as in C, vesea, one-celled, not opening by regular valves, but 
bursting without order when the seed is ripe. When two or 
more hermaphrodite flowers are found crowded so close as 
to press on each other, those when come to maturity, have 
only one common capsule, or envelope. Nuts oval, of a 
pretty hard, ligneous texture, and light brown colour, some- 
what hairy, particularly round the apex. Inside soft and 
hairy, one-celled, evalvular. Seed generally single, conform 
to the nut. IJntegument single, thin, striated, and bairy. 
Perisperm none. Embryo the size and figure of the seed, 
inverse, Plumula two-lobed, Radicle oval, superior.
