L. Cockayne. — Notes on New Zealand Floristic Botany, 189 



33. Ourisia macrocarpa Hook. var. calycina (Col.) Cockayne. 



South Island : Western Botanical District — Mount Tuhua, in herb-field. 

 J. E. Holloway ! 



This variety has been recorded by Mr. D. L. Poppelwell from as far 

 south as the mountains near the Haast Pass, but its exact southern limit — 

 i.e., where it is replaced by var. cordata (the type of the species) — is not yet 

 known. 



34. Plagianthus cymosus T. Kirk. 



South Island : South Otago Botanical District — Banks of Waihopai 

 Stream, near Invercargill. J. Crosby Smith ! 



As Mr. Crosbv Smith's record of this interesting plant in his list of 

 Southland plants (Trans. N.Z. Inst., vol. 46, p. 223, 1914) may be easily 

 overlooked, I am calling attention to this station. 



35. Pseudopanax lineare (Hook, f.) C. Koch. 



South Island : Western Botanical District — In subalpine scrub of Mount 

 Tuhua. J. E. Holloway ! 



36. Ranunculus chordorhizos Hook. f. 



South Island : Eastern Botanical District — Mount Hutt, on subalpine 

 shingle-slip. A. Wall ! 



37. Ranunculus Enysii T. Kirk. 



South Island : Eastern Botanical District — Mount St. Bernard. H. Wall ! 



R. Enysii, according to the Manual, is said to occur not only in the 

 Waimakariri River basin, but also, without there being any stations inter- 

 mediate, on the East Taieri Hills (South Otago Botanical District) and near 

 Lake Harris (Fiord Botanical District). The Taieri station is given on the 

 authority of Buchanan, his Ranunculus tenuis from that locality being con- 

 sidered by Cheeseman as a form of R. Enysii with the leaves more pinnately 

 divided than usual. But R. tenuis Buch. includes not only the Taieri plant 

 but one from Masterton (Ruahine-Cook Botanical District), while the figure 

 (Trans. N.Z. Inst., vol. 20, pi. xii, 1888) does not match any form of 

 R. Enysii from its original habitat ; therefore I think the Taieri habitat 

 should not be accepted. I would also exclude the Lake Harris and 

 Masterton (probably Tararua Mountains) habitats. Should it eventually 

 be proved that I am right, then the species under consideration is, on our 

 present knowledge, confined to the Waimakariri River basin and to the 

 south-eastern portion of the Hurunui River basin, where Professor Wall 

 recently collected it. 



Two very distinct forms of the species were collected by Wall on Mount 

 St. Bernard, and I have also in my herbarium and garden several well- 

 marked form?, but I await cultivation tests before going into the matter 

 of varieties in this rather puzzling aggregate species. 



J. B. Armstrong (Trans. N.Z. Inst., vol. 12, p. 336, 1880) includes 

 Ranunculus geraniifolius Hook. f. in his catalogue of the plants of Canter- 

 bury, but is seems almost certain that the plant he had in mind was 

 R. Enysii, to which R. geraniifolius bears no small resemblance.
