269) are also only varieties of one species with either glabrous or 

 bearded flowers. The leaves of C. acerosa are unusually large in 

 plants produced by the mild climate of Chatham-Island, and very 

 small in the alpine variety (C. parvifolia) ; the veins divergent from 

 the more exterior nerves of the leaves may also be seen in Australian 

 specimina whenever the leaves are widened towards the summit. 

 On a former occasion (conf. Frag. Phyt. Austr. iv. 105) attention 

 has been drawn to the fallibility of the characters on which the 

 diagnosis of Leucopogon juniperinus and L. Fraseri rest ; the latter 

 indeed seems merely an alpine state of the former with a more 

 densely bearded limb of the corolla ; but hitherto only this alpine 

 variety of L. juniperinus and not its taller normal form has been 

 known from New Zealand. Cyathodes abietina shows the degree 

 of pubescence of the corolla to be equally variable. 



Cyathodes acerosa occurs in Tasmania as well on the coast as on 

 alpine summits. In Australia it seems exclusively literal and ex- 

 tends not, as far as known, west of Phillip Island. At Sealer's Cove 

 on granitic declivities occasionally washed by the spray of the sea 

 the plant rises exceptionally to a height of 20' and yields then a 

 stem of I' thickness. When loaded with its carmin-red or pale rose- 

 colored drupes it forms a most showy object in the surrounding 

 vegetation. 



Nearest in afifinity and appearance to C. acerosa are C. glauca 

 and C. abietina; the latter, which forms a shrub 1-2' high on rocks 

 exposed to the sea on the south-coast of Tasmania, differs from the 

 large-leaved variety of C. acerosa in less patent more rigid leaves 

 with thicker nerves, of a pale-green but not glaucous color beneath ; 

 moreover the corolla is generally much larger and often densely 

 bearded, whilst the lobes show no distinctly elevated axis. C. glauca 

 is still more distinct by its leaves, which are crowded in intervals, 

 above perceptibly streaked, less distinctly petioled and of a different 

 nervature of numerous close and fine lines and less pale color beneath, 

 by its sessile flowers, usually evidently bearded corolla of larger size, 

 somewhat exserted filaments, longer anthers and style and often 

 8-10-celled fruits. 



Cyathodes straminea and C. adscendens occur both on the western 

 mountains of Tasmania ; the latter species is transferable to Leuco- 

 pogon, if the position of that genus can be vindicated. 



Cyathodes empetrifolia (J. Hook. Fl. Nov. Zeel. i. 164; Andros- 

 toma empetrifolia, J. Hook. Fl. Antarctic, p. 44, t. 30) produces not 

 rarely 3- or 4-flowered spikes.
