398 SUBANTARCTIC ISLANDS OF NEW ZEALAND. {Systematic Botany. 



Ranunculus aucklandicus, A. Grray. 



Ranunculus aucklandicus, A. Gray, Bot. U.S. Expl. Exped., i, 8 (1854) ; Hook. 

 t, Handb. N.Z. Fl., 723 (1867). R. Hectori, T. Kirk, Students' Fl., 16 (1899). 



Auckland Islands : Usually in wet ground near the sea ; U.S. Expl. Exped., 

 Kirk ! Cockayne ! Aston ! Tennant ! (Endemic.) 



Half -ripe fruiting specimens collected by Aston show that the achenes are villous 

 in the young state. Further study of Kirk's R. Hectori has convinced me that it 

 can only be regarded as a trivial form of R. aucklandicus, and I have therefore rele- 

 gated it to that species. 



Ranunculus acaulis, Banks & Sol. 



Ranunculus acaulis, Banks & Sol. ex D.C. Syst., i, 270 (1818) ; Hook, f., 

 Fl. Antarct., i, 4, t. 2 (1844). 



Auckland Islands : Moist places near the sea ; Hooker, Kirk, Cockayne, Aston ! 

 Tennant ! (Muddy beaches and sandy or gravelly shores, from the North Cape 

 to Stewart Island ; also in the Chatham Islands. Very closely allied to the Chilian 

 R. stenopetalus, Hook., of which it is probably only a recent derivate form.) 



The specimens submitted to me are by no means good, but are apparently identi- 

 cal with the common New Zealand state. Hooker remarks that his specimens " en- 

 tirely agree with others gathered in the Bay of Islands." R. acaulis is the only 

 species of Ranunculus which stretches through the whole length of the Dominion, 

 from the North Cape to the Auckland Islands ; it has thus a latitudinal range of 

 nearly a thousand miles. 



Ranunculus biternatus, Smith. 



Ranunculus hiternatus, Smith in Rees's Cyclop., xxix, n. 48 (1802) ; Wildem., 



Res. Voy. " Belgica," 89, t. 12, f. 12-2 (1906). R. crassi'pes. Hook, f., 



Fl. Antarct., ii, 224, t. 81 (1844) ; A. Hamilton in Trans. N.Z. Inst., 



xxvii, 566 (1895). 



Macquarie Island : Swampy ground near the sea, usually in the shelter of the 



tussocks of Poa foliosa ; A. Hamilton ! (Fuegia ; Falkland Islands ; South Georgia ; 



Kerguelen Island ; Crozets; Marion Island ; New Amsterdam.) 



I have followed Dr. Schenk in uniting the Macquarie and Kerguelen R. crassipes 

 with the Fuegian R. biternatus. R. crassipes was originally distinguished on account 

 of its greater size and less-divided leaves ; but these are characters of small im- 

 portance, and Mr. Hamilton's Macquarie Island specimens have the leaves almost 

 as much divided as those of a Fuegian specimen figured as R. hiternatus in the 

 " Botany of the Voyage of the ' Belgica.' " 



Cruciferae. 

 Cardamine glacialis, D.C, var. subcarnosa, 0. R. Schulz.

0. R. Schulz in Engl. Jahr., xxxii, 542 (1903). 



Stout, succulent, glabrous or nearly so, variable in size, 1-5-12 cm. high. 



Rhizome perennial, stout, spongy, often branched at the top, each division crowned
