Lainq. — Vegetation of Banks Peninsula. 391 



o 



Geum urhanum Linn. var. sfrictum Hook. f. [J. F. A. ; J. B. A. ; L. C] , 



Tussock pastures : Cockayne. 



Acasna novae-zelandiae Kirk var. viridissima Bitter. [J. B. A. ; L. C] 



This is the most abundant form of Acaena on the peninsula, and is 

 everywhere common up to 1,600 ft., particularly in dry open ground. 

 In the forest it is usually replaced by the following, which, however, 

 is by no means so co)nmon. 



Acaetm Sanguisorbae Vahl. var. 



This variety is thus described from my specimens by L. Cockayiie 

 in a letter to me : " Plainly to be distinguished by the dark dull green 

 and but slightly hair}^ upper surface of the leaf, the silvery under- 

 surface with closely appressed hairs, the sepals green edged with purple 

 within and still more hairy and purple without, the frequently trifid 

 stipules, and the rather short stout spines, which vary from pale to rather 

 dark purple." This variety, comparatively rare on the Lyttelton Hills, 

 occurs frequently on the peninsula above 1,500 ft., and at all levels 

 in the forest. 



Acaena Sanguisorbae Vahl. var. pilosa- Kirk. 



This form as described by Kirk (occurs on the southern slopes of 

 Castle Rock and Mount Herbert above the height of 2,000 ft., probably 

 also at Cooper's Knobs. It is at once distinguished from the preceding 

 by its glaucous bluish coloration, with brown serrations. The under- 

 surface of the leaf, the upper margin, the petiole, peduncles, and stem 

 are all markedly pilose. (I am indebted to Dr. Cockayne, who is making 

 a special study of the New Zealand species of the genus, for this 

 identification). 



A fourth form of Acaena {Acaena Sanguisorbae Vahl. var. viridior 

 Cockayne) occurs in a small piece of bush in the Wainui Valley. 



J. B. A. gives also (^)^4. adscendens, but I do not think it occurs. 



Family Leguminosae. 



*{^ )Carniichaelia nana Col. (i). [J. B. A.] 



I have seen specimens belonging, I think, to this species near the 

 top of Mount Herbert, on the northern side. Neither flowers nor fruit 

 were present, and I was unable to identify it with certainty. C. nana 

 is common on the old river-bed of the Waimakariri, seven miles from 

 Christchurch. 



Carmichaelia subulala Kirk. [L. C] 



Abundant in open country from the seashore to upwards of 1,500 ft. 

 This is the only large species on the peninsula. 



J. B. A. records (-)C australis, which does not come south of Pelorus 

 Sound, ('^)G. flagellijormis (probably in error for the above), {-)C. pilosa 

 Col. (?), and with J. F. A., in addition, {'^)C. grandiflora. 



Sojjhora micropkylla J. Miill. [J. F. A. ; J. B. A. ; L. C] 



Common in the forest, and sometimes on the open hillside. 



So'phora prostrata J. Miill. [L. C] 



Common in rocky ground, and here a very distinct species.
