It varies to some extent in the size of the leaves and in habit, but is 

 easily recognized in all its forms. Sometimes the leaves are shorter than 

 in the specimens figured and more closely arranged. 



My specimens were obtained in the vicinity of Eotoiti, not far from 

 the outflow of the lake. I have to acknowledge my indebtedness to Mr. 

 Cheeseman for specimens collected in another habitat lower down the 

 valley.

Umbellieer^. 



Aciphylla traillii, n. s. 



Tufted, glabrous, 3"-6" high, flaccid when fresh. Leaves 2"-4" long, 



spreading, 3-foliolate or quite simple ; leaflets linear, T V broad, acute or 



pungent with a stout marginal nerve on each side, slightly canaliculate, 



entire : petiole and sheath rather broad, membranous. Flowers dioecious : 



scape more or less flexuous, bracts simple, linear, or with one or two short 



segments at its junction with the short inflated base. Male umbels 5-7, 



pedicellate, slender, las, calyx-lobes reduced to points, flowers on slender 



pedicels, minute. Female scape stouter, umbels 5-10, crowded, bracts 



shorter and broader, more rigid, slightly pungent, sheaths broad tumid, 



enclosing the umbel, umbel simple or with a solitary branch, involucral 



leaves extremely minute, flowers shortly pedicelled ; carpels (immature) 



narrowly 5-winged. 



Rah. Near the summit of Mount Anglem, Stewart Island, 2,800 to 

 3,200 feet. 



I have named this distinct little species in compliment to Mr. A. W. 

 Traill who accompanied me during the ascent, and to whom I am indebted 

 for valuable assistance in elucidating the Flora of Stewart Island. 



It is allied to A. lyallii, from which it is distinguished by its smaller size, 

 excessively tufted habit, flaccid leaves and prominent marginal nerves. A 

 single specimen of an Aciphylla collected on Eakiahua by Mr. P. Goyen may 

 be identical with A. traillii, but this could only be determined by the exami- 

 nation of specimens in a more advanced state : the leaves are 5-foliolate, 

 with strict rigid pungent segments and are longer than the scape : the mar- 

 ginal nerves are much stouter.
