Though abundant upon the hills of Lord Auckland and Campbell's Islands, this plant has not hitherto been 

 brought from any part of New Zealand, neither from the mountains of the Northern Island, whence Mr. Bidwill 

 and Mr. Colenso have sent home several of the more common Antarctic species, nor in the southern parts of that 

 group, so well explored by Forster and Menzies. In general habit and appearance it bears a greater similarity 

 to the Phyllachne uliginosa, Forst., than to its New Zealand congener, Forstera sedoides, L., although in the 

 more essential characters it is much more nearly allied to the latter, the leaves being entire, the calycine seg- 

 ments equal and regular, and the epigynous glands much developed. In other respects, and especially in the 

 mode of growth and form of the leaves, the present plant is so dissimilar from either, that I have ventured to 

 place it under a separate sectional name, adopted in allusion to the incrassated apices of the leaves. 



There are several points in the structure of the three plants above alluded to which seem to require some 

 consideration ; and having the opportunity of examining the flowers of all the species, I shall here offer a few 

 remarks upon them, premising that, except in the case of F. clavigera, the specimens at my disposal were too 

 few to allow of the full verification of the observations. 



Linnaeus first supposed Phyllachne to be monoecious (Suppl. Plant, p. 62), and Swartz (Schrader, Journ. 

 fur Botanik, vol. i. p. 273, translated in Koenig's Annals, vol. i. p. 286) follows Forster (Charact. Gen. t. 58) 

 in supposing both this and F. sedifolia to be dioecious. If, as I suspect, the only truly fertile flowers of F. cla- 

 vigera are such as bear the uncinate plumose styles, that plant is certainly monoecious. Out of very many 

 flowers examined, I only found such stigmata in two, both of which had abortive anthers, and they were more- 

 over furnished with the only capsules in which I saw the immature seeds brown, and apparently fertile. Though 

 there is a marked difference in the development of the apex of the style in the abortive flowers of this plant, it 

 never, that I have seen, approaches the form it bears in the fertile flowers ; at all other times it is exceedingly 

 minute and probably variable in the lobes. Of the P. uliginosa 1 examined six flowers, only one of which
