6-8 pairs, gradually diminishing towards the base of the petiole, 
sharply toothed or incised; cauline leaves or bracts few, deeply 
incised. Flowering-stems few or several, erect or spreading, strict, 
terete, clothed with a short fine pubescence intermixed with long 
silky hairs, branched above, forming a few - flowered cymose 
panicle. Flowers small, white, +-4in. diam.; pedicels elongating 
in fruit. Calyx-tube turbinate; lobes ovate-deltoid, acute. Petals 
small, rounded. Fruiting receptacle silky. Achenes numerous, 
spreading, ;4,in. long, perfectly glabrous, oblong-ovoid, somewhat 
turgid, narrowed into a short hooked or spirally recurved style.—

Readily distinguished from all the preceding species by the smooth and 
glabrous achenes narrowed into a very short recurved style. 
6. G. pusillum, Petrie in Trans. N.Z. Inst. xxvii. (1896) 538. 
—Small, depressed, 1-2in. high. Leaves few, all radical, rosu- 
late, obovate-spathulate in outline, #-lin. long, sparsely covered 
with rather long strigose hairs, pinnate; terminal leaflet +-4+in. 
broad, rounded, crenate-toothed ; lateral leaflets 5-8 pairs, gradu- 
ally diminishing in size, bluntly toothed. Scapes 1-2 in. high, 
1-flowered, simple, naked or with 1-3 minute bracts, finely and 
closely pubescent. Flowers minute, white. Calyx-tube broadly 
turbinate ; lobes ovate-deltoid. Petals 5-6, small, elliptic-oblong. 
Fruiting receptacle elongated, villous. Achenes very small, per- 
fectly glabrous, obliquely oblong or obovoid; style minute, reduced 
- to a recurved point.—Kirk, Students’ Fl. 180. 
SourH IsLhanp: Otago—Old Man Range, altitude 5000 ft., Petrie ! 
Allied to G. leiospermum, but separated by the much reduced size, 
1-flowered scapes, smaller flowers, and minute achenes, the style of which is 
reduced to little more than a hooked point. 
3. POTENTILLA, Linn. 
Perennial herbs, rarely shrubs. Leaves either pinnate or digi- 
tately 3-5-foliolate; stipules adnate to the petiole. Flowers soli- 
tary or in corymbose cymes. Calyx persistent, lobes 5 or rarely 4, 
valvate, alternating with as many bracteoles. Petals 5, rarely 4, 
usually broad. Stamens numerous. Disc annular or coating the 
ealyx-tube. Carpels many, rarely few, seated on a small dry 
receptacle; style persistent or deciduous, terminal or lateral ; 
ovule solitary, pendulous. Achenes usually numerous, crowded 
into a head surrounded by the persistent calyx. 
A large genus in the arctic and temperate portions of the Northern Hemi- 
sphere, extending into the mountains of the tropics, but extremely rare in the 
Southern Hemisphere. The New Zealand species is almost cosmopolitan.
