TETRANDRIA— MONOGYNIA. Galium. 203 



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

 glnosum, as well as in its larger size, stouter habit, glaucous 

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

 and terminal bristles, agree. The j^oiuers of the present, however, 

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

 compound pa?iJc/ej; each segment of their corolla tipped with 

 an awn-like point. 



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



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

 anarginal prickles all pointing foi'ward. Stem weak, 

 much branched, smooth. Fruit smooth. Corolla taper- 

 pointed.

Perennial. August. 



Stems loosely spreading, I^ or 2 feet high, repeatedly branched, 

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

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

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

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

 the edges rough, especially tovi^ards 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 

 globular, large. Fruit smooth, or slightly granulated. 



This comes very near G. erectum ; experience must prove how far 

 the differences above indicated are constant. Seeds were sent 

 by M. Thouin, named " G. ciHerewm of DeCandoUe," 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 agreeing therewith. G. austriacum, Jacq. Austr. t. 80, from 

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

 the edges 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. 



Leaves six in a whorl, stalked, lanceolate, flat, reticulated 

 with veins, bristle-pointed, with minute marginal prickles
