(coloured portion). Plant varying in size oe 5 dm. to a metre. 
Principal stem rooting only at the base, generally robust, decumbent 
or ascending. Leaves springing at an acute angle from the stem, 
pinnate, length varying with size of plant, but generally much 
larger than n in var. pseudo-repens or sub epens. Ocrea at base 
e 
stout plants as many as 9-11, elliptic lanceolate or ovate lanceolate, 
normally not lobed except vty oe ed terminal leaflet. 
Leaflets varying usually from 2-4 cm. n length according to size 
of plant. Peduncle of fully developed Lit shorter than rays, some- 
times almost absent, Rays of umbel 4-10. Involucre bracts 0 or 1 
or 2, ** caducous,”’ but fru ruiting umbels in Herb. Mus. Brit. show 
involucral bracts still persisting. Fruit generally slightly longer 
than broad. Primary ridges much more prominent than secondary. 
This is the well-known common ditch form, and is so widel
