Arabis mageilanica Dusén 3 in = Beet. Exp. Haralanstand iii. no. 5, 
Forest, Burmeister Peninsula. 
South Patagonia; Fuegia. 
A remarkable looking plant onginaly described under Brassica, 
to which it was also referred by De olle, and later transferred to 
Sisymbrium by Sir Joseph Hooker. ‘Quite recently Dusén has rele- 
gated it to Arabis, suggesting a comparison with 4d. macloviana 
Hook. f., a very distinct plant. 
There is e evidently considerable variation in the amount of hairi- 
ness. Hooker describes the plant as glaberrimum, in which our speci- 
men agrees, while Dusén says, ‘‘ Closely covered with stellate hairs.”

Mr. Prichard’s specimens apparently represent a much less 
robust na smaller form than that on which Spegazzini based the 
species. The latter is pr as having ‘‘ caudex majusculus 
é . diam.,’ 
mens the stem barely exceeds 2 mm. in thickness ; it may, how- 
ever be a branch of the main stem, which is itself not Bere 
Otherwise our specimens agree with Spegazzini’s descriptio 
type-specimens come from basalt rocks between " Lago 
Musters and Choique- het more than three hundred miles to the 
north-east of Lake Argentino.
