Hah. Euahine Momi tain-range : Mr. A. Olsen ; 1895. 



Obs. This species is near the only other known southern 

 one {G. australasica), but differs in its scape being 2-3 flowered, 

 in its very much larger calyx (a striking character), different - 

 shaped anthers, and bitid instead of trifid stigma. Of G. 

 australasica Hooker says, in first describing it (" Icones 

 Plantarunr," tab. 293), " petalis calycem quadruple super- 

 antibus" — w^iich his plate, with dissections, clearly show; 

 and Bentham, " sepals small orbicular, petals several times 

 longer; style 3-cleft," ttc. (" Fi. Australiensis," vol. i., p. 

 177). 



Order XXVI. Droseeace. 



Genus 1. Drosera, Linn. 



1. D. ruaJiinensls, sp. nov. 



Plant perennial, tufted, erect, sub 2in. high, glabrous ; 

 rootstock long and straight, woody, much fibrously branched ; 

 the whole plant very dark coloured (blackish) when dry. 

 Leaves with petioles Ifin. long, of two forms, ovate-acuminate, 

 and broadly orbicular-spathulate, lamina of the latter very 

 glandular on upper surface ; glands long, flat, flexuous, and 

 straight, dark-red, broadest at base, tips subobovoid ; petioles 

 sub l^in. long, broad, membranous, veined, half -clasping. 

 Scape ^in.— |iu. longer than leaves, filiform, naked. Flower 

 solitary, small, 3 lines long ; calyx lobes broadly-elliptic- 

 oblong, tips slightly jagged. Corolla a little longer than 

 calyx ; petals membranous, suborbicular, entire, whitish 

 tinged with rose-colour, veined. Stamens flat, broad, shorter 

 than calyx, included ; anthers cordate, yellow. Styles 3, 

 short, stout ; stigmas capitate, large, papillose ; ovary sub- 

 ellipsoid-globular. 



Hab. Euahine Mountain-range : Mr. H. Hill, 1895 ; Mr. 

 A. Olsen, 1895. 



Obs. A species having affinity with D. arcturi, Hook., and 

 D. polyneura. Col. (Trans. N.Z. Inst., vol. xxii., p. 460), but 

 differing from both in several grave characters. 



2. D. stylosa, sp. nov. 



Plant slender, weak, suberect ; stem 10in.-12in. high, dark- 

 green, almost black (so also stem-leaves and -sepals), striate, 

 slightly branched, 1-2 small branches near top, each bearing 

 2-3 leaves and a single terminal flower. Leaves rosulate, 

 9-10, broadly orbicular, 2 lines wide, glandular on upper 

 surface and at margins (glands in centre of lamina very short 

 and small), glabrous below, pale yellow-brow^n ; petioles flat, 

 stout, -^^in. long. Stem-leaves broadly lunate and peltate, 

 2 lines wide, much glandular on upper surface ; glands flattish, 

 long (irregular lengths), strong, spreading, those of the two
