ovate to oblong-spathulate, gradually narrowed into a petiole of equal 
length or longer. Cauline leaves in 1-3 remote opposite pairs, 4-310. 
long, petioles short or almost wanting. Flowers solitary, terminal, large for 
the size of the plant, }-2in. diam., white. Calyx divided about j-way 
down into 4 oblong-lanceolate acute lobes, with an evident midrib. Corolla 
deeply divided, twice as long as the calyx; lobes obtuse. Stamens rather 
longer than the calyx. :

—End Peak, Lake Hauroko, Crosby Smith ! 2500-4500 ft. January—March. 
Mr. Petrie considers this to be nearest to G. lineata, from which it appears tome to 
be widely different. I should place it in the vicinity of G@. bellidifolia. = belicd « peter .

17. G. divisa,Cheesem. Man. N.Z. Fl. (1906) 453.—Stems slender, erect, 
excessively branched from the base, often forming hemispherical masses 
2-9in. diam. Radical leaves very numerous, rosulate, 1-3 in. long, oblong- 
or obovate-spathulate, rounded at the tip, gradually narrowed into broad 
flat petioles, usually rather thin and membranous, 3-5-nerved. Cauline 
leaves similar but smaller and on shorter petioles or the uppermost sessile. 
Flowers very numerous, in dense or lax corymbose cymes, sometimes almost 
concealing the leaves, about 2in. diam., white. Calyx rather more than 
1 the length of the corolla, divided ?-way down or more; lobes linear- 
oblong, obtuse or subacute. Corolla deeply divided ; lobes oblong, rounded 
at the tip.—G. bellidifolia vars. divisa, vaccilata, and magnifica 7. Kirk om

from the Spenser Mountains southwards, but not common. 1000-3500 ft. 
TAis has a remarkably distinct habit, often forming compact globose masses 3—9 in. 
diam., so densely covered with flowers as to resemble large snowballs. Mr. Kirk 
made three varieties of it; but the differences are so slight that they are best treated 
as forms of one variable plant. “TT, 7° TO “~~ WA: BAe 
18. G. Astoni Petrie in Trans. N.Z. Inst. xiviii (1916) 187.—Perennial ; 
root usually slender. Stems numerous, perfectly glabrous, very variable 
in habit of growth, erect or spreading or even entangled or trailing, much 
or sparingly branched, long.or short, 6-12 or 18in. long. Leaves in 
opposite pairs, almost connate at the base, $—-}1in. long, linear or narrow 
linear-spathulate, acute or subacute, somewhat flaccid, midrib obscure ; 
margins more or less recurved. Flowers freely produced, terminating 
the main branches or axillary in the upper leaves, white, $—$in. long; 
peduncles slender, erect, rather shorter than the leaves. Calyx obconie, 
cut almost to the base into 5 linear-subulate lobes. Corolla much longer 
than the calyx, deeply divided into 5 oblong-lanceolate acute lobes. Stamens 
and pistil about 4 the length of the corolla.

19. G. Spenceri 7. Kirk in Trans. N.Z. Inst. xxvui (1895) 835—Annual ; 
stems few or many from the root, slender, erect, 4-10in. high. Radical 
leaves numerous, rosulate 1-2in. long, broadly ovate- or obovate- 
spathulate, rounded at the tip, narrowed into a broad petiole as long or 
longer than the blade, 3- or rarely 5-nerved ; cauline few, rather narrower
