TETRANDRIA— MONOGYNIA. Galium. 203 



forward By this the present plant differs essentially from G. uli- 

 ginosum, a/ well as in its larger size, s^touter habit, glaucous 

 hue and larirer less obovate leaves, though their discoloured tips, 

 and'terminal' bristles, agree. The>^fer.of the present, however, 

 are larner far more numerous, and crowded into dense, terminal, 

 compound panicles ; each segment of their coro//a tipped with 

 an awn-like point. 



7. G. chiereum. Grey Spreading Bed-straw. 



Leaves six or eight in a whorl, linear, bristle-pointed, with 

 marginal prickles all pointing forward. Stem weak, 

 much branched, smooth. Fruit smooth. Corolla taper- 

 pointed.

leafy, smooth, pale, or somewhat glaucous, quadiangular, one 

 or two of the angles sometimes doubled. Leaves 8 in a whorl on 

 the main stem 3 6 on the branches ; linear, scarcely at all lan- 

 ceolate, destitute of veiny reticulations, smooth on both sides, 

 the ed^es rou^h, especially towards the point, with sharp, shal- 

 low serratures, or close bristles, hardly more than a simple, 

 strictly marginal, row, pointing forwards. Panicles terminating 

 the stem and upper branches, 3-forked, corymbose ■ the upper 

 ones aggregate Stalks quite smooth. Cor. white, larger than 

 in the last, with horizontal segments, each tipped with a short, 

 taper, not bristly, point, various in length and direction. Stigmas 

 P-lobular, large. Fruit smooth, or slightly granulated. 



Thik comes verv near G. erectum ; experience must prove how far 

 the ditlerences above indicated are constant. Seeds were s^^^^^^ 

 by M Thouin, named - G. cinereum of DeCandolle and plants 

 raised from them flowered in August 1815, near Norwich. I 

 have a wild one from the late Mr. G. Don, as a new species ex- 

 actly an-rcein^ therewith. G. austriacum, Jacq. Austr. t. bU, ti-om 

 the author, comes nearer to this than the figure indicates ; but 

 the edj^es of its leaves are either quite smooth, or rough with a 

 few recurved prickles. The leaves of these 3 species are more 

 or less revolute, at least when dry. 



8. G. aristatum. Bearded Bed-straw. 

 Loaves six in a whorl, stalked, lanceolate, flat, reticiilated 

 with veins, bristle-pointed, with minute marginal prick.es
