* 

 Tt'ibe 8. PeucedanecE. Fruit more or less compressed dorsally, surrounded 



with a single dilated entire smooth margin, which is flattened or slightly 



convex, but not thickened at the edge. Carpels with five filiform or rarely 



winged ribs, of which the lateral ones are contiguous to the dilated margin 



or united with it. Seed flattened, or convex on the back. Rare in 



western Europe, northern America, and the Canaries ; more abundant in 



northern India and South Africa. Examples : *Peucedanum, *Pastinaca, 



Anethum. 



Tribe 9. Silerinece. Fruit multijugate, the ribs but little elevated, 

 especially the secondary ; carpels compressed externally. Inhabit central 

 Europe and northern Asia. Examples : Siler, Galbanum. 



Tribe 10. Cuminece. Fruit contracted at the sides. Carpels wdth five 

 primary filiform ribs, of which the lateral ones are marginal ; and four 

 more prominent secondary ones ; all of them wingless. Seed straight, 

 flattish on the face. Umbels compound. Found in Mediterranean 

 Europe and in North America. Examples : *Trepocarpus, Cuminum. 



Tribe 11. Thapsiecp,. Fruit either dorsally compressed or nearly terete. 

 Carpels with five filiform, often bristly, primary ribs, of which the lateral 

 ones are placed on the face of the commissure : secondary ribs four ; the 

 dorsal ones filiform and the lateral ones winged ; or all of them winged 

 (hence the fruit is either eight-winged, or only two-winged on each side). 

 Seed flattish, or somewhat teretely convex, plane pn the face. Umbels 

 compound. Central Europe and north-western America. Examples : 

 *Laserpitium, Thapsia. 



Tribe 12. Daucinecs. Fruit lenticularly compressed on the back, or 

 somewhat terete. Carpels with five filiform bristly primary ribs, of which

 Mexican. Example : Elseoselinum, Margotia. 



Tribe 14. CaucalinecB. Fruit laterally contracted or somewhat terete. 

 Carpels with five primary bristly or prickly ribs, of which the lateral ones 

 are in the commissure ; secondary ribs four, more prominent and prickly, 

 or sometimes obliterated by the copious prickles filling the entire intervals. 

 Seed involute, or with the margin inflexed. Umbels compound. Distri- 

 bution as in Daucinese ; one North American species. Examples r 

 *Caucalis, Torilis. 



Tribe 15. Scandicinece. Fruit compressed or contracted laterally, usually
