88 PENTANDRIA— DIGYNIA. Pimpinella. 



having an elliptic-obiongyrw//, and no calyx. The foliage 

 moreover is of a very different character. I am not en- 

 tirely convinced that the kind of hairiness observed on the 

 friut of Athamanta, is a good generic, or even a specific 

 mark, however important the prickles ofji-iiits, properly 

 termed armed^ in this natural order, may be.

On Gogmagog hills, Cambridgeshire. Ray, Relhan. Between St. 

 Albans and Stoney Stratford. Hudson. 



Perennial. August. 



Root tapering, a little woody, bitterish and pungent, crowned with 

 the fibrous remains of old footstalks. Herbage extremely vari- 

 able in luxuriance. Sietn from 1 to 2 or 3 feet high, firm, erect, 

 angular and deeply furrowed, solid, smooth, leafy principally in 

 the lower part. Radical leaves stalked, twice or thrice pinnate, 

 in foreign specimens still more compound ; leaflets opposite, 

 deeply and sharply cut, smooth ; the lowermost crowded, and 

 often crossing each other. Umbels terminal, on long, upright, 

 furrowed stalks, convex, of many stout, angular, downy general 

 rays, and still more numerous partial ones. Bracteas both ge- 

 neral and partial numerous, linear-lanceolate, taper-pointed, 

 downy. Fl. crowded, white or reddish. The styles and their 

 tumid bases assume a violet hue after the flowers are past. The 

 umbels are sometimes proliferous. Whether the hairiness of the 

 fruit be an essential character or not, this plant cannot belong 

 to Ligusticum, as the ribs of that part are not winged,
