TETRANDR1A— MONOGYNIA. Galium. 203 



whitish or glaucous, square, except immediately under the 

 whorls, where they acquire intermediate angles, and are some- 

 what hairy, though otherwise smooth. Leaves lanceolate, 

 scarcely at all obovate, except some of the lower ones, a little 

 glaucous, copiously reticulated with veins j smooth on both sides, 

 even the midrib ; but the edges, and the adjoining portion of the 

 disk above, bear a double row of hooked prickles, all directed 

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

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

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

 and terminal bristles, agree. Thejlowers of the present, however, 

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

 compound panicles ,• each segment of their corolla tipped with 

 an awn-like point.

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

 marginal prickles all pointing forward. Stem weak, 

 much branched, smooth. Fruit smooth. Corolla ta- 

 per-pointed.

Perennial. August. 



Stems loosely spreading, 1± 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 j 6 on the branches ; linear, scarcely at all lan- 

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

 the edges rough, 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 j 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. cinereum of DeCandolle," and plants 

 raised from them flowered in August 1815, near Norwich. 1 

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

 actly agreeing therewith. G. austriacum, Jacq. Austr. t. SO, from 

 the author, comes nearer to this than the figure indicates 5 but 

 the edges of its leaves are either quite smooth, or rough with a
