it more readily from H. pratense by attending to the fringed 

 glume, and the greater length of the awns of the corolla of 

 the lateral flower, than the awns of their calyx. 



37. ^^orAewm. pratense. — Near Warrington, August, 1825. 

 — There is also in this a bristle at the base of the inner valve 

 of the central corolla, as in H. murinum ; it is about half as 

 long as the valve. In the lateral flowers, the calyx-valves are 

 not fringed, and their awns are much longer than those of 

 the corolla. 



38. yioniia. fontana. — Wales, June, 1826. — Stem round, 

 dichotomously branched. Leaves spathulate and sessile? 

 Flowers in axillary branches : flower-stalk at first bent down- 

 wards, but on the ripening of the seeds, erect and elongated, 

 sometimes branched or divided. — Wales, May, 1828. — 6 or 

 7 inches long, an ovate and rather pointed hractea at the 

 base of each cluster o^ flowers. Corolla, indeed, monopetalous, 

 but cleft on one side almost to the base of the tube, between 

 two of the smaller segments of the limb, as if an intermediate 

 segment were wanting. Filaments inserted at the base of the 

 segments, not at the " base of the corolla." Seed with a lateral 

 embryo, bent round the albumen : outer skin granulated and 

 shining. 



39. Galium palustre. — The transition from the smooth to 

 the rough state of this plant may be observed on the borders 

 of pools, and it is only in very wet situations that it cor- 

 responds with the description in Eng. Fl. In dry places, 

 especially by road-sides, in Wales, where the earth has been 

 recently disturbed, (in the neighbourhood of marshes,) it 

 assumes the state of G. Witheringii, and is very luxuriant 

 and branched. In marshes, not liable to be overflowed, and 

 in boggy ground, it is in every respect like that described 

 in Eng. Fl. under G. Witheringii. The leaves are 5 or 6 in 

 a whorl, linear-obovate, blunt, and deflexed : the stem thick- 

 ened above the whorl. 



40. Rubia joerep'rma. — Wales, June, 1826. — Corolla rotate, 

 not bell-shaped, (nor funnel-shaped as in R. tinctoria:) seg- 

 ments, after impregnation, spreading with convex surfaces,
