■wider (Todaroa^); sometimes rather thick little raised suberose 

 (Xatardia^); secondary not conspi<3uous or very rarely slightly 

 prominent {Portenschlagia '). Vittse in furrows solitary or more rarely 

 2-nate, sometimes broad (Portenschlagia) ; the intrajugal sometimes 

 more or less conspicuous {Stenocoelium* Buhonopsis ^). Mericarps 

 sometimes hirsute broader {Scaphespermum^) or a little longer; 

 ridges short (Lomatopodium.'') Carpophore 2-partite or 2-fid. Face 

 of seed flat or slightly concave, sometimes more concave (Diplolo- 

 phium '). — Perennial or biennial herbs, glabrous, pubescent or tomen- 

 tose ; leaves ternato-pinnately dissected or decompound, sometimes 

 pinnately decompound (Xatardia) ; umbels compound ; involucral 

 bracts oo , membranous free {piplolophium, Libanotis ') or at base 

 more or less connate in cupule (Hippomarathroides ""), sometimes few, 

 very small or (Todaroa, Xatardia) ; bracteoles of involucels oo , rarely 

 (Todaroa) few or 0. (North, temp. reg. of Old World, trop. E. Africa?^) 

 37? Sclerochorton Boiss.'^ — Flowers'' polygamous; sepals den- 

 tiform. Petals obovate concave, at apex within produced to incurved 

 lacinule. Style elongate. Fruit sessile (nearly of Seseli), subterete ; 

 mericarps compressed. Eidges 5, rather prominent. Vittse in furrows 

 6, 7, very thin flexuose. Commissure broad, to 10-vittate. Seed con- 

 caveat face. — Perennial many-stemmed herbs ; leaves rigid decompound 

 in petiolate lacinules ; umbels compound ; fertile flowers and fruit girt 

 at base with sterile male flowers or pedicels.'* (Persia, Greece}^)
