XI. PASTINACA. Tourn.; Linn.; DC. 
Margin of the calyx obsolete or minutely toothed. Petals roundish, entire, 
involute, the involute part broad and retuse. Fruit flat-compressed dorsally, 
surrounded by a dilated flattened margin. Mericarps with very slender 
ridges ; the dorsal and 2 intermediate ones equidistant, the lateral contiguous 
to the dilated margin. Vitte linear, scarcely shorter than the ridges, solitary 
in each interstice, 2 or more on the commissura. Carpophore bipartite. Seed 
flattened.—Herbaceous plants with a fusiform and often fleshy root. Leaves 
pinnated, the segments toothed, cut or lobed. Umbel compound. Involu- 
cre and involucel wanting or few-leaved. Flowers usually yellow. 
1148. (1) P. Candolleana (W. & A.:) stem striated or slightly furrowed, 
glabrous below, pubescent below the umbels and on the rays: leaves pubes- 
cent ; ultimate divisions pinnatifid or lobed, their segments oblong acuminat- 
ed and sharply serrated: leaflets of the involucre and involucel deciduous, 
linear-oblong: margin of the calyx toothed : fruit oblong, glabrous ; lateral 
vittæ close to the intermediate ridges; commissura with 2 vittse.— Wight ! 
eat. n. 1202. 
The flowers appear white. 
1149. (2) P. /igusticifolia (W. & A.:) stem slightly striated or almost even, 
glabrous Asc rtm e the am and m ca rays: leaves glabrous ; 
ultimate divisions pinnatifid or lobed ; their segments ovate, acute, serrated : 
leaflets of the involucre and involucel linear-oblong, acuminated, deciduous : 
margin of the calyx inconspicuously toothed : fruit oval, very glabrous, po- 
lished ; lateral vittæ close to the intermediate ridges; commissura with 2 vit- - 
tee.— Wight! cat. n. 1203. 
Our specimens of both these species are imperfect: they are no doubt 
closely allied, but appear distinct. 
XII. HERACLEUM. Linn. ; Lam. ill. t. 200; DC. 
Calyx 5-toothed. Petals obovate, emarginate, with the point inflexed ; 
the exterior ones often larger, spreading and bifid. Fruit dorsally flat-com- 
pressed, surrounded by a dilated flattened margin. Mericarps with very 
slender ridges, the dorsal and intermediate ones equidistant ; the two late- 
ral ones remote and contiguous to the dilated margin. Vittæ solitary in t 
interstices, or rarely in pairs in the lateral ones, usually 2 but sometimes 4 or 
none on the commissura, all shorter than the fruit and usually club-s: 
Carpophore bipartite. Seed flattened.—Herbaceous and usually large plants. 
Leaves pinnated, ternate, or lobed: petioles amply sheat ing. Umbels with 
many rays. Involucre deciduous, usually few-leaved. Involucel many- 
leaved.
