— Ls without the membranous edge, the upper ones broader, 
clasping at the base. Ijivolucel-leaflets broad, elliptic. 
B. Burserianum Sclil. (larger form).— b. cannlense Wulf. 
(caricifolium Rchb. not Willd.) Stem often taller and 
more branched; ls only 2—3 mm broad; umbellules and 
especially the involucels smaller. Probably a good species!

1. Rt. fusiform. Ls 2—3-pinnatisect, with very numerous,

— Rt. fascicled. Ls 1 —3-pinnatisect, the cauline with long, 
linear segments. FIs of the circumference pedicelled, 
often sterile, those of the centre almost sessile, fertile 2 
2. The pinnatisect portion of the caul, ls shorter than the 
hollow petiole. Umbels with 2—4 (the lateral, later ones 
with 3—6) rays.—Marshy meadows, ditches, rare and 
almost only on the plains of western Switz. 6 
fistulosa L. 955. 
— The pinnatisect portion of the caul, ls longer than the

1. Ls 2—3-pinnatisect, entirely glabr., shining underneath, 
and emitting a foetid smell when rubbed. Stem 20 —45 cm , 
among stubble, only 2 — 8 cm (v. agrestis), on the rich 
soil of woods often 120—150 cm (v. elata). Yery easily 
recognised by the 3 long leaflets of the involucel being 
bent back and turned downwards!—Distrib. 6

1. Ls several times pinnatisect, with long,' linear-filiform

*) O. peucedanifolia Poll., a W. European species, differs in its napi- 
form rt.-fibres which are oval or elongated, sessile, thickened from the base 
and terminated by a long fibre, in its umbels of 6—10 rays, longer styles 
and earlier bloom. This species is not found in this country.
