thick corky pericarp, which also contains 5 small bundles of 

 strengthening cells. Seed-section oval or much flattened. 



* * * * Acauleiicent or nearly so, with soliiary or numerous oil-tubes, 

 no stylopodium, filiform dorsal and intermediate ribs (prominent or even 

 siigiitly winged in some species of Cnlnpfera and in PMeudocymopfenao 

 and variously colored flowers. 



14. Coloptera. Calyx-teeth obsolete or exident. Fruit 

 ovate, glabrous. Carpel with dorsal and intei-mediate ribs filiform 

 or winged and approximate; lateral wings broad, very thick and 

 corky, with neither nerves nor strengthening cells, coherent till 

 maturity with those of the other cai-pel, forrning a broad corky 

 margin to the fruit usually thicker than the fi'uit proper, and in 

 cross-section showing a neck-like connection. Oil-tubes very 

 small, 4 to 8 in the intervals, 8 to 14 on the commitjsural side. 

 Seed very flat, with plane or slightly concave face. Dwarf plants, 

 with small simply pinnate (bipinnate in one sjDccies) or lobed leaves. 



15. Leptotaenia. Calyx-teeth obsolete or evident. Fruit 

 oblong-elliptical, glabrous. Carpel as in Coloptera^ except that 

 the thick corky lateral wings have large groups of thick-walled 

 strengthening cells, and the dorsal and intermediates are always 

 filiform or obscure; conimissural face with a prominent central 

 longitudinal ridge left after separation from the carpophore. Oil- 

 tubes 8 to 6 in the intervals, 4 to 6 on the commissural side, 

 mostly small, sometimes obsolete. Seed very flat, with plane or 

 slightly concave face. Tall and stout, with large pinnately de- 

 compound leaves. 



1(5. Peucedanum. Calyx-teeth obsolete or evident (rarely 

 much enlarged). Fruit oblong to suborbicular, glabrous to tomen- 

 tose. Carpel with dorsal and intermediate ribs filiform and ap- 

 proximate; lateral wings broad and thin, coherent till maturity 

 with those of the other carpel, forming a broad membranous wing 

 to the fruit ; commissural face without a prominent longitudinal 

 ridge after separation from the carpophore; a group of strengthen- 

 ing cells beneath each rib. Oil-tubes 1 to 8 in the intervals, 2 to 

 10 on the commissural side. Seed flat, with plane or slightly con- 

 cave face. 



17. PseudocymopteruS. Calyx-teeth evident. Fruit ovate 

 or oblong. Carpel with dorsal and intermediate ribs very promi-
