 /.) Petals obovate, entire, with an inflexed point. Stylopodium 



thick ; styles very short (f. 56. D.g.). Fruit compressed from 

 the back (f. 56. D. k.), girded by a thick dilated margin ; the 3 

 dorsal ribs crested, approximate : the 2 lateral ones running into 

 the margin ; dorsal vittae very few, the commissural ones wanting 

 or covered. Involucra and involucels of many leaves. Flowers 

 yellow. 



108 SYMPHYOI.6MA. Margin of calyx obsolete. Petals equal, 

 emarginate, with an inflexed point. Stylopodium without a mar- 

 gin ; styles reflexed. Fruit elliptic, compressed from the back ; 

 mericarps closely connate by their margins ; with 5 filiform ribs : 

 3 dorsal ribs equi-distant : lateral ones more remote, margin- 

 ating ; vittae wanting or obsolete. Seed flattened. Carpophore 

 none. Flowers red. 



109 HERACLE'UM. Calyx 5-toothed. Petals obovate, emar- 

 ginate, with an inflexed point : exterior petals usually radiating 

 and bifid. Fruit compressed from the back, girded by a flat, di- 

 lated margin ; mericarps with very fine ribs : 3 dorsal ones equi- 

 distant : 2 lateral ones remote, contiguous to the dilated margin : 

 vittae 4 on the back, solitary in the furrows, but usually with 2 

 in the commissure, all shorter than the fruit, and usually club- 

 shaped ; carpophore bipartite. Seed flat. Involucra caducous, 

 usually of few leaves ; involucels of many leaves. 



110 ZOZI'MIA. Calyx 5-toothed. Petals obovate, emargi- 

 nate, with an inflexed point. Fruit compressed from the back, 

 rather convex in the middle, hairy, girded by a smooth, thick- 

 ened, dilated margin ; ribs very thin : dorsal ones at equal dis- 

 tances : 2 lateral ones more remote, contiguous to the dilated 

 margin ; vittse covering the whole seed, solitary in the furrows, 

 and twin in the commissure. Carpophore bipartite. Seed flat. 

 Involucra and involucels of many leaves. 



111 POLYTS'NIA. Calyx 5-toothed. Petals oval, emargi- 

 nate, with an inflexed point. Fruit oval, compressed on the 

 back, convex in the middle, glabrous ; with a smooth tumid 

 margin, and a depressed furrow on the back ; ribs very 

 slender, hardly distinct ; vittae twin between the ribs, but 6 in 

 the commissure ; carpophore indistinct. Seed flat. Involucra 

 none ; involucels setaceous. 



112 JOHRENIA. Teeth of calyx obsolete, very blunt. Petals 

 unknown. Stylopodium short, conical, furrowed a little. Styles 

 short, diverging. Fruit oval, lenticularly compressed on the 

 back (f. 56. C. &.), quite glabrous; with a smooth tumid mar- 

 gin, and a flat, dorsal, coloured furrow ; mericarps with 3 dor- 

 sal, filiform ribs, which probably contain villas : 2 lateral ones 

 running into the dilated margin, hardly distinct, usually rufous, 

 and the form of vittae ; commissure spongy, furnished with 2 

 lines, but without vittae. Carpophore 2-parted(f. 56. C.b.a.). 

 Seed flat. Involucrum wanting, or of 1 leaf; involucels of 4-5 

 linear, setaceous leaves. 



TRIBE VIII. 



TORDYLI'NE.*:. Fruit lenticularly or flatly compressed from 

 the back, girded by a thickened, nodulose, or plaited, dilated mar- 

 gin. Mericarps with 5 veryjine or obsolete ribs : lateral ones con- 

 tiguous to the dilated margin, or forming the same. Seeds flat- 



tened. This tribe differs from Peucedaneee in the margin of the 

 fruit being plaited or nodulose, not smooth and entire. 



113 HASSELQUI'STIA. Margin of calyx 5-toothed. Petals 

 obovate, emarginate, with an inflexed point ; outer petals radi- 

 ating and bifid. The outer fruit of the umbel are compressed, 

 girded by an accessory, winged, thickened margin, which is 

 hardly wrinkled ; those of the disk dissimilar : one of the meri- 

 carps contracted into an hemispherical urceolus around the other, 

 which is abortive ; ribs very slender : the 3 dorsal ones equi- 

 distant : and the 2 lateral ones contiguous to the thickened mar- 

 gin, or hidden by it ; vittae 1 in each furrow, and 2 in the com- 

 missure. Carpophore bipartite. Seed flat. Involucra of many 

 leaves. 



114 TORDY'LIUM. All as in Hasselquistia, except that the 

 vittae are either solitary or numerous in the furrows, and either 

 2 or more in the commissure ; and in the fruit being equal, and 

 girded by a tubercularly wrinkled, accessory, thickened margin. 

 Involucra of many leaves. 



115 TORDYLOPSIS. Margin of calyx 5-toothed ; teeth acute : 

 outer teeth the largest, dilated at the base, and cuspidate at 

 the apex. Outer petals of umbels larger, and obcordately 2- 

 lobed : the rest smaller, ovate, and cuspidate, usually entire, rarely 

 somewhat 2-lobed. Stylopodium conical. Styles erect, elon- 

 gated. Fruit hairy. Involucra and involucels of 5-6 lanceolate- 

 linear leaves. 



* * Fruit furnished with both primary and secondary ribs. 

 TRIBE IX. 



SILERI'KE*. Fruit lenlicularly compressed from the back. 

 Mericarps with 5 primary ribs : the lateral ones marginating ; 

 and usually with 4 secondary, less prominent ones ; all filiform 

 and wingless. Seeds flattish in the front. 



116 KRUBE'RA. Margin of calyx 5-toothed. Petals obo- 

 vate, emarginate, with an inflexed point. Mericarps with 5 

 plicately crenated, thick ribs : the 3 intermediate elevated, ob- 

 tuse, and keeled : 2 lateral marginating and roundish, keeled 

 near the raphe ; vittae none. Carpophore bifid. Involucra 2- 

 5-leaved ; involucels 4-5-leaved. 



117 PACHYPLEU'RUM. Margin of calyx obsolete, or minutely 

 denticulated. Petals permanent ; those of the inner flowers 

 obovate-oblong, emarginate, with an acute, inflexed point ; those 

 of the ray flowers of 2 forms : the 3 inner, ovate, hardly emar- 

 ginate, with an acute inflexed point : 2 outer nearly orbicular, 

 and profoundly emarginate, also with an inflexed point. Meri- 

 carps with elevated, thick, and corky ribs : the lateral ones mar- 

 ginating, and a little broader than the others ; vittae none In- 

 volucra and involucels of many leaves. 



118 AGASY'LLIS. Margin of calyx obsolete. Petals lanceo- 

 late, incurved. Fruit oval. Mericarps with 5 primary ribs : 

 the 2 lateral ones placed in front of the accessory margin ; the 

 secondary ribs hardly visible. Seeds furnished with 8-10 dorsal 

 vittae, and 5-6 commissural ones. Involucra wanting; invo- 

 lucels of many setaceous leaves. 



119 STENOCCE V LIUM. Margin of calyx 5-toothed. Petals 

 obovately orbicular, somewhat emarginate, with art inflexed
