2 LXVIII, UMBELLIFERZ (HIERN). 
minute, near the apex of the seed, straight ; radicle superior.—Herbs, 
rarely shrubs, very rarely trees, annual, biennial, or perennial. Leaves 
alternate or rarely subopposite, frequently decompound, usually mem 
branous; petioles sheathing or amplexicaul at the base, and usually 
without separate stipules. Flowers often polygamous, arranged in ter- 
minal or lateral, simple or compound umbels, which in some cases are 
reduced to capitula. Bracts and bracteoles usually present, forming re- 
spectively the involucres and involucels. 
A large family abounding in temperate latitudes, especially in the Northern hemi- 
sphere, but represented more or less in nearly all parts of the world. 
Five genera are endemic in Africa, and three in Tropical Asia.
