FAMILY 186. UMBELLIFERAE 



Mostly herbs with a jointed stem. Leaves alternate, rarely (Drusa) opposite, 

 usually dissected and with a sheathing stalk. Flowers in umbels or heads, 

 rarely in spikes or in racemed false-whorls, regular or the outermost flowers 

 of the inflorescence somewhat irregular, usually hermaphrodite. Calyx-limb 

 usually faintly developed or wanting. Petals 5, free, usually bent inwards 

 at the tip and therefoie apparently notched or 2-lobed, valvate or siightly 

 imbricate in bud. Stamens 5, alternating with the petals. Ovary inferior, 

 2-celled, rarely one cell onh- fertile, very rarely ovary 3-celled. Ovules 

 solitary in each cell, pendulous, inverted, with ventral raphe. Styles 2, free, 

 arising from a more or less distinctly 2-lobed disc (stylopod), rarely {Lagoecia) 

 style simple. Fruit dry, usually separating into 2 mericarps attached to the 

 2-parted, more rarely 2 -cleft, simple, or obsolete carpophore. Pericarp ribbed 

 and usually traversed by oil-channels commonly situated in the furrows between 

 the primary ribs which as a rule enclose vascular bundles. Seeds with an adnate 

 testa, a horny albumen, and a small embryo with flat cotyledons. — Genera 92, 

 species 410. {APIACEAE.) (Plate 119.) 

 I. T'ruit with a woody rind, without a free carpophore. Oil-channels wanting, 

 more rarely small and situated beneath the primary ribs. Seeds rather 

 flat on the inner face. Petals straight, rarely bent inwards at the point 

 and thread-shaped. Flowers in solitary or fascicled simple umbels or in 

 racemed false-whorls, rarely {Hermas) in compound umbels. Leaves un- 

 divided, lobed, or 3-parted. [Subfamfly HYDROCOTYLOIDEAE.] . 2
