II. I can quite fancy it becoming an interesting and useful 

 scientific study in " days to come " for some future botanist 

 to take up those three species (P. alvina, P. nivalis, and 

 P. montana), and, being well supplied with fresh specimens of 

 them all in their various states, to enter on a close and ex- 

 haustive examination and dissection of them, to ascertain 

 whether they are not varieties of one mountain species. 



Class II. MONOCOTYLEDONS. 

 Order I. Orchidej3. 

 Genus 11. Caladenia, Br. 

 1. C. macrophylla, sp. nov. 



Stem stout below, glabrous ; slender above with leaves 

 and flowers glandular-hairy, 4in. high. Leaves 2 together 

 within 1 sheath near base, 1-J-in. from it, the larger and outer 

 leaf ovate acuminate acute, 2in. long, lin. broad, 6-veined, 

 margins ciliolate with weak white ciliolge ; the inner one 

 much smaller, sublanceolate acuminate ; green, brownish- 

 spotted, chartaceous ; at top of scape a sheathing bract acu- 

 minate half embracing ovary, both also glandular-hairy. 

 Flower single, sub lin. broad expanded, whitish with a tinge 

 of pink, membranous. Dorsal sepal obovate-oblong, much 

 veined, incurved, tip subacute ; lateral sepals 7 lines long, 

 linear oblong acuminate ; lateral petals shorter and narrower, 

 linear subacute; labellum oblong-obovate, no claw, veined, 

 tip rounded, 2 rows of small yellowish ridgy calli subcon- 

 )k ited, one on each side of the middle line from the middle 

 of labellum to base, increasing in size downwards, column 

 largely incurved, the tip hooded, winged laterally and equally 

 throughout. Ovary long, slender. 



Hab. Ruahine mountain-range, east side; 1894: Mr. A. 

 Olsen. 



Obs. A plant that has caused me much trouble as to fixing 

 its proper genus ; it is certainly near G. (?) bifolia, Hook. f. 

 (Chiloglottis, Mueller), and, were it not for its completely- 

 hooded column, from its wings being continued unbroken over 

 it, I should have preferred placing it under Chiloglottis, this 

 genus having its "column 2-fid at the tip" (Hook., I.e., p 

 269). 



Order VII. Liliace^e. 



Genus 4. Dianella, Lamarck. 



1. D. reflexa, sp. nov. 



Leaves distichous, sheathing at base, 20in.-24in. long, 6-7 

 lines wide, subcoriaceous, linear acuminate, green on both 

 sides, shining above, margins and keel (prominent) entire, or
