I. DAUCINE^. 



1. Daucus T. — Flowers hermaphrodite or polygamous, regular or 

 oftener (the exterior of the inflorescence) irregular ; receptacle saclike 

 compressed ovoid, bearing adnate germen within and at the margin 

 the perianth and stamens. Calyx very small 5-toothed or 0. Petals 

 generally unequal and the larger the more anterior, obovate-cuneate 

 or rather broader at the base ; inflexed, induplicate or involute at the 

 point ; on account of the impressed rib above emarginate or more or 

 less deeply 2-lobed ; in prefloration reduplicate-valvate. Stamens 5, 

 inserted with the perianth under the margin of the stylopod ; fila- 

 ments inflexed ; anthers short or sub-2-dymouSj 2-celled, introrse or 

 2-rimose to margin. Germen inferior, 2-celled. Ovule in cells 1, 

 descending ; funicle rather long ; micropyle extrorsely superior. 

 Styles 2, short or elongate, slender, erect or recurved, stigmatose at 

 apex, externally at base dilated to thick conical depressed or pulvinate 

 stylopod, entire undulate or crenate at margin. Fruit oval or oblong, 

 transversely subterete or dorsally or more rarely laterally sHghtly 

 compressed ; mericarps plane or sulcate on face ; primary and secondary 

 dorsal ridges vertically somewhat prominent ; the latter always 

 stronger ; all or the secondary only aculeate or setiferous or muricu- 

 late ; the prickles of the primary ridges oftener short, l-oo -setose ; 

 of the secondary larger, 1-2- or more rarely 3-seriate, dilated at 

 base ; apex rigid or sharp -pointed, straight or hooked ; at base some- 

 times more or less connate in a wing. Vittse solitary in secondary 

 ridges, sometimes very thin. Carpophore undivided or 2-fid. Fruit 

 sometimes (Ammiopsis) oblong-ovate, rather compressed laterally ; 

 commissure slightly constricted ; ridges of subterete mericarps very 

 little prominent ; secondary prominent granulately rugose ; vittge
