Systematic Botany.] SUBANTARCTIC ISLANDS OF NEW ZEALAND. 397 



III. ENUMEEATION OF THE PHANEROGAMS, FERNS, AND LYCOPODIACEAE HITHERTO 

 COLLECTED IN THE ISLANDS TO THE SOUTH OF NEW ZEALAND, INCLUDING 

 THE SNARES, AUCKLAND AND CAMPBELL ISLANDS, ANTIPODES ISLAND, AND 

 MACQUARIE ISLAND. 



Ranunculaceae. 

 Ranunculus pinguis, Hook. f. 



Ranunculus finquis, Hook, f., Fl. Antarct., i, 3, t. 1 (1844); R. 'pinguis, 

 var. h. Hook, i., Handb. N.Z. FL, 5 (1864). 



Auckland Islands : Not uncommon throughout the whole of the group, 

 from sea-level to an elevation of 1,400 ft. ; Hooker, Kirk ! Cockayne ! Aston ! 

 Tennant ! Campbell Island : From sea-level to 1,200 ft. ; Hooker, Filhol ! Kirk ! 

 (Endemic.) 



Varies greatly in size, attaining its greatest luxuriance in sheltered hollows on 

 peaty soil. Specimens collected by Dr. Cockayne on the hills above Camp Cove, 

 Carnley Harbour, are quite 14 in. high, with a stout 2-flowered scape, and the leaves 

 are considerably more than 2 in. across. On the other hand, I possess two specimens 

 gathered by Kirk in Campbell Island which barely exceed \^ in. in total height, and 

 in which the blade of the leaf is not more than | in. diam., ovate-rhomboid or 

 cuneate-rhomboid in outline, with 2-3 coarse teeth at the tip. This form is evi- 

 dently identical with Hooker's variety rhomhifolius (" Flora Antarctica," 3), but 

 it cannot be looked upon as being more than a depauperated state induced by 

 exposure, &c. 



In the " Handbook of the New Zealand Flora " Hooker united R. pinguis with 

 the New Zealand R. Monroi ; but that species differs altogether in the more con- 

 stantly branched scapes, in the more numerous flowers, in the much larger petals, 

 which are always considerably longer than the sepals, and in the more slender 

 style. In the " Manual of the New Zealand Flora " I have therefore followed Mr. 

 Kirk in reaffirming the distinctness of the two plants. 



Ranunculus subscaposus, Hook. f. 



Ranunculus subscaposus. Hook, f., Fl. Antarct., i, 5 (1844). 



Campbell Island : Banks of streams, not common ; Lyall, Filhol ! Rathouis ! 

 Kirk ! Laing ! (Endemic.) 



This is very closely allied to the following species ; in fact, I am not at all sure 

 that the two are really distinct. Its distinguishing characters, such as they are, lie 

 mainly in the ovate-deltoid leaves, which are usually 3-partite to the base, the seg- 

 ments or leaflets being acutely 3-5-lobed. In. R. aucklandicus the leaves are broader 

 and more cordate, with a reniform or rounded outline, and are seldom completely 

 3-partite, and the segments are more obtusely lobed. Fruiting specimens of R. 

 subscaposus gathered by Kirk show the achenes to be ovate, compressed, and dis- 

 tinctly margined, and the style is short and only very slightly hooked. According 

 to Asa Gray, the achenes of R. aucklandicus are not margined ; but, as none of the 

 specimens obtained of late years has ripe fruit, I cannot say whether this statement 

 is strictly correct.
