" Discovered in Britain by 3Ir Anderson." Fl. — Tj . — " Finding- in 

 this some apparently distinqlive characters, we venture, after much hesi- 

 tation, to add another presumed species to a section of the genus of which 

 almost every species is doubtful," Borr,, who further suggests that my 

 specimens of S. petrcca with partially silky germens, mentioned under the 

 last species, probably belong to the present. 



* 15. Bicolores, Borr. Leaves glabrous, or nearly so, dark green

Banks of the Lochy, near Killin. Fl. May. T? . — Nearly allied to S. 

 laurina, (S. hicolor, E. Bot. t. 1S06,) with which, according to Mr

 " leaves elliptic-oblong acute waved and slightly serrated, nearly 

 glabrous glaucous beneath, footstalks dilated at the base, 

 stipules pointed serrated, scales obtuse hairy, half as long as the

Killin in Broadalbane. F/. Apr. Tj . — Resembles .S. laurina in the 

 figure of tlie leaves ; but that plant ditiers by its more acutely angled 

 ramification ; its mahogany-coloured twigs, densely cottony while young, 

 the abundance of short oppressed hairs on both surfaces of the \'oung 

 leaves ; the more subulate germen, white all over with cottony hairs ; 

 and the shorter stylo, with short stigmas, the segments of which usually 

 adhere together. Borr.
