I bave no hesitation in referring this plant to Persoon's Brassica Magellanica, Delessert's excellent figure being very characteristic, in all respects, save that the stellated hairs on the pods are not represented. It is apparently a little known species, Mr. Darwin's and Capt. King's specimens being all I have seen. De Candolle describes the pods as glabrous and torulose, but he evidently has only seen them when young.

The most southern species of the genus, and also found at Valdivia by Mr. Bridges (n. 560) ; it is closely allied to another undescribed plant, A. Cliiloeme mihi, differing in the much larger flowers and leaves, more slender peduncles and longer pedicels. The aestivation of the calyx in this genus is valvate, the segments 5 and of nearly equal size ; the stamens generally indefinite, with some of the outer ones abortive, but in A. Celastrina, where they are few, and none are abortive, the outer series is replaced by five small thickened glands. In A. micro-
