or even three come together, and are then surrounded hy the 

 same scaly calycle, or involucre to be mentioned under tlic 

 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 Avhich 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. vesca, 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 othei', 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 roiuid the apex. Inside soft and 

 hairy, one-celled, evalvular. Seed generally single, conform 

 to the nut. Interjumeiit single, thin, striated, and hairy. 

 Perisperm none. Embryo the size and figure of the seed, 

 inverse. Plumula two-lobed. Radicle oval, superior.

From Canton in China, it has been introduced into the Bo-
