Essai, p. 81. R. leucantha. Bastard, Suppl. Y\. Maine et Loire, p. 32 ; 

 De Cand. PI. France, vol. v. p. 535 ; Lois. Not. p. 82 ; Lejeune, Fl. 

 Sp. vol. ii. p. 347. R. collina, var. obtusifolia, Dumort. Eos. Belg. 

 p. 58. — It has the lithe green branches, small white flowers, and 

 small neat leaflets, at first hairy on both sides and permanently so be- 

 neath, of R. tomentella, atid agrees also with that variety in its fruit 

 and sepals, diftering from it principally in the serratures of the leaves, 

 being quite simple, and from R. frondosa, Stev., in the leaves being 

 at first hairy above, and more decidedly so in the lower surface. 



R. tomentosa. Mr. James Ward has found near Eichmond, in York- 

 shire, a form of this species, which comes very near to Dumortier's 

 R. cinerascens (Dumort. Prodr. PL Belg. p. 98 ; Eos. Belg. p. 50; 

 Deseglise, Toment, p. 31). It has slender straight prickles, densely 

 aciculate, subglobose fruit, and more decidedly softly-grey- downy leaf- 

 lets than is usual in tomentosa, with erecto-patent, nearly simple teeth. 

 He has also found in the same neighbourhood another form of tomen- 

 tosa, with the peduncle and calyx-tube quite naked, but with the leaves 

 much less decidedly grey-velvety than in Hailstone's Blair Athol plant 

 referred by Deseglise to R. farinosa, Kan (see Baker, Linn. Proc. vol. xi. 

 p. 217). 



R. arvensis, Huds. This is clearly the same plant as R. repens of 

 Scopoli, and, according to Professor Crepin in his recently pub- 

 lished ' Primitise ' (p. 31), this latter name takes priority, Hudson's 

 name going back to 1762, and Scopoli's to 1760. R. repens is de- 

 scribed clearly in the second edition of Scopoli's ' Flora Carniolica ' 

 (1772), but I have no opportunity of referring to the first to verify 

 the accuracy of this statement.

Galium cruciafum. — This plant, which, as the sequel will show, has 

 good claim to rank among the plants indigenous to Ireland, is not in- 

 cluded in either the ' Flora ' or the ' Cybele Hibernica.' The first 

 notice of it in Ireland is by K'Eogh', who published in 1735, and 

 describes the plant, under the English name " Crosswort," so mi- 

 nutely as to leave no manner of doubt as to its identification. Harris,
