268 WILSON’S OBSERVATIONS. 
41. Arctium Lappa. Near Bangor, August, 1826. Var. - 
à. Seeds compressed, corrugated, about 9 ribbed, the tops 
of the ribs forming a knobbed crown.  Pappus with erect 
spinule. Tube of the floret permanent, swelled at the base, 
forming a beak to the seed. 
42. Serratula tinctoria. Wales, July 29, 1826. Florets 
with a cylindrical tube. Limb suddenly swelled out, not so 
deeply divided as in the next, and the segments more 
spreading. Anthers protruded half their length beyond 
their florets, without any projection at the base. Filaments 
downy. Stigmas projecting more than in S. alpina and the 
segments sooner reflexed. Style downy, oblique, the outer 
ones much spreading. Seed-down irregular in length, rough 
with erect spinulæ, not feathery. Receptacles rather bristly 
than chaffy, the bristles in tufts. 
43. Serratula alpina. Near Twll dà, July 29, 1826. 
The stem somewhat angular, in consequence of the midrib 
of the leaves being continued down it. Leaves with long 
entangled downy fibres underneath, on the upper side granu- 
lated, free from pubescence. Florets with an angular taper- 
ing tube. Limb much swelled at the base and divided into 
5 deep, lanceolate erect segments. Anthers projecting beyond 
the corolla, with two long hairy projections at the base on 
the inner side of the filaments. Stigma just protruded beyond 
the anthers, two-parted, segments erect and close at first, 
subsequently reflexed. Style downy just below the stigma, 
oblique, pressing: the anthers outwards so as sometimes to 
burst the tube.: « Seed-down irregular, that of the inner 
florets longest ‘and most feathery. Receptacle chaffy, but 
often resembling the last. 
44. Cnicus palustris. October, 1826. The outer scales of 
the calyx have a black viscid gland upon the keel. 
45. Bidens tripartita. August, 1826. Leaves rather cut 
than serrate; with a double row of spinule along the some- 
what thickened margin, very observable also on the bracteas 
which are spathulate rather than lanceolate, and apparently ; 
united at the base, I should rather have considered them an
