portion of stem, nearly equal in size, 9-12 inches long, 2-4 inches broad, 

 ovate, acute at top and tapering into a long flat petiole, which in the lower 

 leaves are covered at bottom with long silky hairs, margins minutely serrate, 

 both sides clothed with closely appressed white tomentum which is thicker 

 on the under side. Veins numerous, running nearly parallel at an acute 

 angle. Flowers in globular heads. Heads numerous, ^— f inch diameter, 

 racemose, and occupying one-third of the stem, pedicellate, pedicels very 

 narrow, 1-3 inches long, bracteate, and covered with white tomentum. 

 Flowers of the ray few, of the disc numerous, involucral scales in several 

 series narrow, tapering to a long point, pilose on the back. 



Common on the hills round Perseverance Harbour, Campbell Island. 

 The notice of a small Pleurophyllum in the Antarctic Flora, p. 33, no doubt 

 refers to the present species, although it now proves to be an abundant 

 plant and much larger than then supposed. It is remarkable that so con- 

 spicuous a plant should have escaped notice, and this can only be explained 

 by its not having hitherto been seen in flower, although the absence of the 

 large lower leaves might have attracted attention. Many of the present 

 species were seen in flower in the latter end of December, while few of 

 Pleurophyllum crinitum, Hook, fil., had developed racemes at that time.
