ral ones often bifid, the uppermost ones resembling bracteas, 
small, entire. Flowers moderately large, on terminal and 
lateral, simple, or mostly nice peduncles, which latter, 
as well as the inferior germen, are hispid with glandular 
hairs. Calyx superior, glabrous, of five erect, oblong, ob- 
tuse, erect segments. Petals obovato-cuneate, pure white, 
retuse, three-nerved below. Stamens alternately shorter. 
Styles two, small, abortive ? (in the present individual). 
The present very pretty species of SaxrrracE was sent by 
Joun Hunneman, Esq. of London, from the continent, to 
the Glasgow Botanic Garden, under the name of Saxirr. 
Pone. Authors seem now to be generally agreed, in con- 
sidering this as identical with S. petrea : and, indeed, the 
specimens quite accord with the true S. petrea, which I 
have gathered abundantly in Savoy, upon the “ Petit 
Mont Cenis.” It is a native also of the Monte Baldo in 
the north of Italy, and of the Carinthian Alps, while the 
same plant has been introduced to our collections by Mr. 
Drummonp, from the Rocky Mountains of North America. 
It is quite a hardy plant, and flowers in May.
