This extremely rare plant has been introduced to our gar- 
dens very recently from Germany, and in the spring of the pre- 
sent year has produced flowers, both in our own garden and in 
that of Edinburgh. These individuals, however, being dwarf-— 
ish, and considerably smaller than the wild specimens which I 
have received through my kind friend Dr Hornscuvucn, I 
have represented the figure of the natural size, from one in my 
herbarium, and the parts of fructification from garden plants. 
Its native country is the Alps of Carinthia and Salzburg, 
where it has been found by Messrs SterNBERG and Hoppr. 
By them the genus Braya was established, in a work to which, 
unfortunately, I have at this time no access) Dre CaNDOLLE 
was not acquainted with the perfect seeds: hence he has, in 
his Systema Vegetabilium, referred this genus to a division 
having the cotyledons accumbent. This character alone, suf- 
fices to remove Braya from Arabis, as also from Mr Brown’s 
Parraya, while from Platypetalum it may be known by its 
longer, linear seedvessel, and from Hutrema by the cylindrical, 
not ancipitate, siliqua. ‘Two other species are known to us, 
the B. glabrella of Ricuarpson, and the B. arctica, which 
I first established in the yet unedited Appendix to Captain 
_ Parry’s second voyage.
