502 ROSACEAE. [Geum. 
terminal corymbose panicle or solitary. Calyx persistent ; lobes 5, usually 
alternating with 5 bracteoles. Petals 5. Stamens numerous, crowded. 
Carpels many; ovules solitary, erect; style terminal, filiform, elongating 
much after flowering, bent at or below the end. Achenes numerous, com- 
pressed, crowded on a dry receptacle, each one terminated by the persistent 
elongated naked or plumose style. 
A genus comprising about 40 species, spread through the temperate and cold 
regions of both the Northern and Southern Hemispheres. One of the New Zealand 
species is widely distributed, another occurs in temperate South America, the rest 
are endemic.

G. alpinum Buch. in Trans. N.Z. Inst. xix (1887) 216 is quite unknown to me, and 
there are no specimens in his herbarium. The original description is vague and 
insufficient, and the name had far better be dropped. 
1. G. urbanum Linn. Sp. Plant. (1753) n. 501 var. strietum.—An 
erect sparingly branched herb 1-3 ft. high, usually softly pubescent or 
villous in all its parts. Radical leaves very variable in size, 4-18 in. long 
including the petiole, pinnate ; leaflets 3-5 pairs with much smaller ones 
intermixed, 1-3in. long, ovate or obovate, cuneate at the base, sessile, 
variously toothed lobed or pinnatifid. Cauline leaves few, smaller, with 
fewer and more sharply toothed leaflets, sessile or nearly so ; stipules leafy, 
coarsely toothed or lobed. Flowers $—3in. diam., yellow, few together 
in a loose terminal panicle; peduncles slender, erect. Calyx-lobes ovate, 
acuminate, reflexed in fruit. Petals obovate, exceeding the calyx. 
Achenes very numerous, forming a dense oblong head, spreading and 
recurved, hispid with long silky hairs; awn long, hooked at the tip.—

North AnD Sourn Istanps: Not uncommon from the Paparata Valley and — 
Waikato River southward. Sea-level to nearly 3000 ft. November—January. 
The New Zealand variety has a wide distribution in the Southern Hemisphere, 
and is found in some parts of Asia as well. It differs from the European G. urbanum 
principally in the taller and more robust habit and larger fowers. 
2. G. parviflorum Sm. in Rees Cyclop. (1802) 12.—An erect or spreading 
perennial herb 4-18 in. high, everywhere clothed with silky or villous hairs, 
sometimes almost shaggy ; rootstock stout, woody. Radical leaves 2—5 in. 
long, pinnate ; terminal leaflet very large, #-2in. diam., rounded-reniform, 
obscurely 3—5-lobed, crenate, hairy on both surfaces; lateral leaflets 4-8 
pairs, all minute, deeply cut and lobed. Cauline leaves or bracts few,
