O' 



thickened with a circular pore above, hght-green, margins 

 recurved. Flowers terminal, on a long slender erect scape 

 2 in. long, bearing 2 flowers on short pedicels with 5 bracts at 

 their bases half as long as perianths ; bracts linear-lanceolate- 

 obtuse, reddish-green (as also calyx), their tips shghtly ciliolate. 

 calyx-lobes oblong, 1-nerved, tips knobbed. Corolla longer 

 than calyx, lobes broadly oblong-obtuse, membranaceous. 

 Column summit subreniform, longitudinally trisulcated, ovary 

 dark- reddish. 



Hab. Euahine Mountain-range, east side ; 1898 : Mr. H. 

 Hill. 



Obs. A much larger and stouter plant in all its parts than 

 F. sedifolia, from the same locality, and nearly allied to 

 F. truncatella, mihi (Trans. N.Z. Inst., vol. xx., p. 196). 



Order XLI. Campanulace^. 



Genus 1. Wahlenbergia, Schrader. 



1. W. 'pygtnaa, sp. nov. 



Plant very small, |-in. high, simple, tufted, glabrous; root 

 2 in. long, slender, hard, white ; sometimes 2-4 branches 

 (tufts) rising distantly from one long branched root. Leaves 

 radical, numerous, sub 20, close, spreading, somewhat ver- 

 ticillate, linear-spathulate, 4 lines long (including petiole), 1 

 line broad, tip rounded very obtuse, with 2 small crenulate 

 serratures on each side, tapering gradually to base, pale- 

 green, shining. Flower large (for plant), solitary, terminal, 

 drooping; scape -^in.— |in. high, very slender, bare. Calyx 

 campanulate, 2 lines long, dark-green, 5-lobed ; lobes cut half- 

 way down, linear-acuminate-obtuse, 1-nerved. Corolla 5 lines 

 long, sub ^iu. diameter, white, lobes pale-blue, 2-nerved, tri- 

 angular, subacute, half length of corolla. Style fiat, 2-nerved, 

 densely minutely tuberculate on each side and upwards to 

 top of stigma ; stigmas 2, oblong-lanceolate. 



Hab. Euahine Mountain-range, west side, near summits; 

 1848: W. G. East side; 1898: Mr. A. Olsen. 



Obs. This is a peculiarly striking little plant, from its 

 uniform size and pleasing appearance, a rather large droop- 

 ing bell-flower springing from its little squarrose moss-like 

 tuft of leaves. As I first made its acquaintance in its alpine 

 habitat fifty years ago, and sent specimens to England — pro- 

 bably not quite perfect — I think it may have been considered 

 as identical with W. saxicola, A. DC, but that plant is different 

 in several characters ; a good drawing of it, with dissections, is 

 given by Sir W. J. Hooker in "Icones Plantarum" (tab. 818), 

 under the name of W. albomarginata.
