Cheeseman. — Flora of Neio Zealand. 271 



Ranunculus insignis. 



Moist ravines on the slopes of Tongariro and Kuapehu, but 

 not common ; T. F. C. 



Ranunculus nivicola. 



Tongariro, Ngauruhoe, and Ruapehu ; altitude, 3,500- 

 6,000 ft. ; abundant, usually in sheltered hollows or in localities 

 where it is more or less shaded by scrub or rocks ; T. F. C. 



Although plentiful, it does not form such a prominent feature 

 of the vegetation as on Mount Egmont, nor does it attain the 

 same size. 



Ranunculus parviflorus, var. australis. 



I have received specimens of this collected on Tiritiri Island 

 by Mr. A. Hansen. So far as I am aware, this is the only 

 locality in which it has been found in New Zealand outside the 

 Auckland Isthmus. 



III. Cruciper^;. 

 Cardamine. 



A most elaborate and painstaking monograph of Cardamine, 

 by Dr. 0. E. Schulz, is printed in Engler's " Botanischen Jahr- 

 buchern" for 1903 (vol. 32, pp. 280-623). With respect to 

 the New Zealand species, the author excludes from the genus 

 more than half those included in it by Hooker, as C. stylosa, 

 C. fastigiata, C. latesiliqua, and C. Enysii. In this he is pro- 

 bably right ; for, as I have pointed out in the Manual, the 

 fruit of these species does not at all agree with the characters 

 of Cardamine as usually accepted. With regard to those re- 

 tained in the genus, he revives Forster's name of heteropkylla 

 for the plant which Hooker referred to the northern C. hirsuta ; 

 a species which Schulz insists does not occur anywhere in the 

 Southern Hemisphere. Hooker's variety corymbosa of C. hirsuta 

 he restores to specific rank ; the variety subcarnosa he transfers, 

 as a variety, to the South American C. glacialis ; while C. de- 

 pressa of the Handbook he splits up into the two species" C. 

 depressa and C. stellata of the " Flora Antarctica." With Kirk's 

 C. bilobata he does not seem to be acquainted. His arrange- 

 ment is therefore as follows : — 



1. C. heteropkylla, O. E. Schulz. 



Var. micrantha. 

 Var. macrantha. 

 Var. leiocarpa. 

 Var. hirtella. 

 Var. macrostylis. 



2. C. corymbosa, Hook. f. 



3. C. glacialis, D.C., var. subcarnosa.
