the germ : stigmas obtuse : there is no pericar- 

 pium : common receptacle of the seeds round- 

 ish, juiceless, very small, permanent, covered 

 with seeds, inclosed within the calyx: the seeds 

 numerous, acuminate-wrinkled. 



The species chiefly cultivated arc : I. P. frn- 

 tieasa, Shrubby Cinquefoil ; -• P. J ra ga r io ides, 

 Strawberry-leaved Cinquefoil ; 3. P. recta, Up- 

 right Cinquefoil ; 4. P. Mtmspclicnais, Montpe- 

 her Cinquefoil ; 5. P. gramlifiora, Great-flow- 

 ered Cinquefoil. 



Other species may he cultivated for variety. 



In the first, the whole plant is set with tine 

 silvery hairs: the stems erect, clothed with a 

 brown b3rk which cracks longitudinally, branch- 

 ing very much, nbout three feet (or in gardens 

 four feet) high, frequently reddish : the leaves 

 alternate, covering the branches, petioled, qui- 

 nate-pinnate, or consisting of five rarely seven 

 oblong leaflets, somewhat rolled back, quite 

 entire, hairv underneath ; the upper ones ter- 

 nate. Dr. Withering remarks, however, that 

 the leaves can h.irdlv be called pinnate, consist- 

 ing of two pairs set cross-wise, rising from the 

 same point, with a terminating one divided 

 down to the base into three open segments ; and 

 that the leaflets are linear-lanceolate, turned 

 back at the edges, dark green above, pale un- 

 derneath. Flowers terminating, solitary, pe- 

 duncled, of a bright yellow or golden colour, 

 and very ornamental. It is a native of Oeland, 

 England, Siberia, and China, flowering here in 

 June and July. 



It has a beautiful appearance, in its numerous 

 flowers. 



The second species has the root somewhat tu- 

 berous : the leaves silky on hairy petioles, with 

 three, five, or seven leaflets, which are ovate, 

 opposite, serrate, lessening as thev approach 

 the base : the runners are decumbent. It is a 

 native of Siberia. 



The third has a stem about a foot high, rigid, 

 covered with a pile rather than hairs, reddish, 

 at top corymbed, or dividing into several pe- 

 duncles forming a sort of umbel : the leaves are 

 large, having each five or seven oblong villose 

 -. frequently of a russet colour, with ten 

 or twelve blunt teeth , when old almost naked : 

 the lower ones are peti-oled, the upper ones ses- 

 sde, finally becoming linear and stipular. The 

 flowers are abundant on the top of the stein, 

 erect on solitary peduncles, altogether makum 

 the stem panicled. It is a native of Germain and 

 the South of Europe, flowering in June and July. 



The fourth species is a perennial plant: the 

 stalks grow erect, about a foot high ; thev are 

 very hairy : the leaflets oblong, serrate : the pe- 

 duncles come out above the joints of the stalk :

the flowers are white and large : the) eon. 



in June; and the ,-ecds ripen in autumn. It is 



a native of the South of France. 



The fifth has also a perennial root : the stems 

 trailing : the leaflets ovate, obtuse, bluntly in- 

 dented on their edges : the flowers larger than 

 in the fourth sort, and the whole plant "l a 

 deeper green. It flowers in Julv, and the seeds 

 ripen in autumn. It is a native of Switzerland 

 and Siberia. 



Culture. — The first sort may be readily in- 

 creased by sucker-, layers, and cuttings, which 

 may be laid down or planted out in the autumn 

 or spring season, and be removed into the nur- 

 sery in the spring following ; and after having 

 two or three years growth in that situation, 

 they will be fit for planting out in the clumps 

 and shrubbery borders. 



When removed from their natural situations 

 into these places, the best season is in the au- 

 tumn, before the frosts 'begin, that they may 

 get well rooted. Thev should be watered occa- 

 sionally in dry weather. 



Thev succeed best in a cool moist soil and 

 shady situation. 



All the other kinds may be increased by part- 

 ing the roots, and planting them out in the au- 

 tumn, or by sowing the seeds either in the au- 

 tumn or spring seasons. 



Thev all afford ornament and variety in the 

 different parts of pleasure-grounds. 



POTERIUM, a genus containing plants of 

 the herbaceous and shrubbv perennial kinds. 



It belongs to the class and order Monoecia 

 Polyandria, and ranks in the natural order of 

 Miscellanea?. 



The characters are : that the calyx is a four^ 

 leaved perianth: leaflets ovate, coloured, cadu- 

 cous : the corolla four-parted : segment? ovale, 

 concave, spreading, permanent: the stamina 

 have very many filaments, (thirty to fifty) capil- 

 lary, verv long, flaccid : anthers roundish, 

 twin. — Female flowers in the same spike abov< 

 the males : the calyx a perianth as in the male: 

 the corolla one-petalled, wheel-shaped: tub* 

 short, roundish, converging at the mou'h: 

 border live-parted : segments ovate, flat, r 

 permanent : the pistillum has twi . - blong 



germs, within the tube of the corolla : styles 

 two, capillary, coloured, flaccid, the length of 

 the corolla: Btigmas pencil-form, coloured: the 

 pericarpium is a berry formed of 'he tube <<j 

 the corolla, hardened, thickened, elosed: the 

 - two : inverted.
