o" 



Obs. I. A distinct species, allied to C.parviflora, but widely 

 different in sepals and anthers. 



II. Named in honour of its discoverer, Mr. Henry Hill, 

 F.G.S., Inspector of Schools, who has often visited that 

 mountain region, bringing therefrom many of its botanical 

 novelties, described by me in papers in the Transactions. 



Genus 3. Ranunculus, Linn. 



1. B. uniflora, sp. nov. 



Plant very small, perennial, tufted, erect, spreading, about 

 1 in. high. Rootstock hard, woody ; rootlets few, wiry, 

 descending. Leaves few, 4-6, subdeltoid, 2-3 lines long, tri- 

 foliolate ; lobes suborbicular, sessile, entire, terminal one 

 largest, 1-1^ lines broad, lateral much smaller, thickish, veins 

 obsolete, light-green; petioles ^in.-f in. long, stout, sheathing 

 half-w^ay up ; sheaths large, membranous, white. Flowers 

 soUtary, one on each plant ; scape stout, shorter than petioles, 

 with a spathe-like bract encircling stem a little below calyx, 

 white, membranous. Sepals 3, suborbicular, very thin, pale- 

 yellow. Petals 4, yellow, shining, obovate-spathulate ; claw 

 narrow ; nectary below middle, foveolate. Filaments short ; 

 anthers elliptic. Achenes few, turgid, roughish ; tips filiform, 

 curved ; head of fruit small, green. 



Hab. Waikaremoana, Hawke's Bay; October, 1898 : Mr. 

 H. Hill. 



Obs. A species near B. ac^tulis, Banks and Solander, but 

 differing in several characters— e.(/., not stoloniferous, leaflets 

 always entire, petioles largely sheathing, scape with a bracteo- 

 late spathe under calyx, petals fewer and differently shaped, 

 and achenes roughish. In size, too, it is much smaller than 

 B. acaulis. This very small size is general; I have upwards 

 of a dozen plants, which are nearly alike. I may further 

 remark that B. acaulis is largely delineated with dissections 

 in Hooker's "Flora Antarctica": Auckland and Campbell 

 Islands, vol. i. 



Order III. Crucifer^. 

 Genus 4. Cardamine, Linn. 



1. C. xanthina, sp. nov. 



Plant herb, perennial, small, depressed; leaves spreading 

 horizontally, subrosulate ; root long, thick, white, tapering. 

 Leaves radical, numerous, imbricate, with a few on flowering- 

 stem near its base, glabrous and slightly hairy, spathulate- 

 acute, l-|in.-2|-in. long, membranous, much and deeply cut, 

 sinuate -lobed, subpinnatifid ; lobes regularly opposite their 

 margins, variously cut and toothed, decreasing gradually to
