12. Heracleum L.' — Flowers nearly of Peucedanum ; sepals small 

 or 0. Petals ' often rayed, cuneate or unguiculate at base, spuriously 

 2-lobed or emarginate. Germen generally pubescent. Stylopods 

 conical, often marginately undulate, sometimes very small. Fruit 

 elliptical or obovate, sometimes suborbicular (of Peucedanum) ; at 

 margin oftener not tumid, sometimes rather thickened (Trigonoscia- 

 dium ') ; vittse in furrows oftener solitary, rarely 2, 3, generally shorter 

 than mericarp, more or less enlarged below, rarely equal to fruit; 

 sometimes in addition some very thin intrajugal vittse. Carpophore 

 2-partite. Seed much compressed, face generally flat. . Other cha- 

 racters of Peucedanum. — Herbs, oftener perennial, either low, or 

 oftener very high, generally pubescent, scabrous or hirsute ; leaves 

 lobed or pinnately or ternately dissected ; umbels compound ; bracts 

 of involucre small ^ or rather large (Tordyliopsis *), sometimes 0; 

 bracteoles of involucels cx> . (North, temp, regions of both hemispheres.^) 



13. Symphyoloma C. A. Mey.^ — Flowers nearly of Heracleum; 

 petals subequal, spuriously 2-lobed, apex pointed and much inflexed. 

 Styles erect rather short ; stylopods depressed conical, crenulate at 

 margin. Fruit ' sub-elKptical, much compressed parallel to septum ; 

 margin rather thick aUform entire simple. Mericarps highly connate, 

 not separable ; margins contiguous only before maturity ; carpophore 

 0. Dorsal and lateral dorsal ridges linear scarcely prominent. Vittse 

 0. Seed much compressed, flat at face, in one cell oftener minute 

 aborted. — Herbs nearly stemless; flowers radical pinnate, 1-2-ribbed; 

 segments unequal rather broad crenate ; the terminal ' larger ; 

 flowers* in sparsely'" compound or simple umbels subequal to
