specimens. They all belong to an unusually small state, barely more than Jin. 

 high, but they have the grassy and almost flaccid, leaves of the type. 



Colobanthus subulatus, Hook. f. 



Sagina suhulata, D'Urv., Fl. Malouines in Mem. Soc. Linn. Paris, iv, 617 

 (1826). Colobanthus Benthamianus, Fenzl in Ann. Wien Mus., i, 49 

 (1836). G. subulatus, Hook, f., Fl. Antarct., i, 13 (1844). 



Auckland Islands : Exact locality not stated ; Aston ! Campbell Island : Rocky 

 places near the summits of the hills ; Hooker, Kirk ! (Victoria ; Fuegia ; Falkland 

 Islands ; South Georgia.) 



Very closely allied to the New Zealand C. acicularis, which differs in the much 

 longer acicular points to the leaves, and in the much longer and narrower sepals, 

 which are linear-subulate and considerably exceed the capsule, whereas in C. subulatus 

 they are about the same length. The New Zealand plants referred by Hooker to 

 C subulatus are in all probability small forms of C acicularis. 



The plate of C. subulatus given in the " Flora Antarctica," based on Falkland 

 Island specimens, represents a plant with a much more lax habit than the Auckland 

 Island or Campbell Island species, and the sepals are only four in number instead 

 of five. It appears to me that the specific identity of the two plants is open to 

 doubt ; but, as I have not seen American specimens, I leave the question in 

 abeyance for the present. 



In the Manual I adopted the specific name of Benthamianus, that being the 

 oldest name under the genus Colobanthus. But now that the Vienna Congress has 

 definitely ruled that the oldest name under any genus must take precedence it will 

 be necessary to go back to the name subulatus, which was published by D'Urville 

 (under Sagina) in 1826, whereas Benthamianus did not appear until 1836.

Montia fontana, Linn. 



Montia fontana, Linn., Sp. Plant., 87 (1753) ; Hook, f., Fl. Antarct., i, 13 

 (1844). 



Auckland and Campbell Islands, Antipodes Island, Macquarie Island : Moist 

 places near the sea ; abundant. (Generally distributed throughout the North and 

 South Temperate Zones.) 



Geraniaceae. 



Geranium microphyllum, Hook. f. 



Geranium microphyllum, Hook, f., Fl. Antarct., i, 8, t. 5 (1844). 



Auckland and Campbell Islands : Not uncommon in moist places ; Hooker, 

 Kirk ! Aston ! Laing ! (Throughout New Zealand ; and very close to an Australian 

 plant.) 



Judging from Hooker's plate and from the few specimens I have seen, the Auck- 

 land and Campbell Islands plant is smaller in size and has a more slender habit than 

 is usual in New Zealand.
