figure of fhe eamnio'n Guilder Rose, and like 

 that almost entirely composed of radiated abor- 

 tive flowers, of a beautiful rose-colour, inodo- 

 rous, green when young as well as in decay : the 

 flower-stalks are variously subdivided, smooth, 

 sometimes hairy : partial ones of a deep rose- 

 colour, roundish. It is much valued on ac- 

 count of the great profusion of its elegant 

 flowers. It is commonly cultivated in the gar- 

 dens of China and Japan. 



Culture. — The lirst is increased by slipping 

 ■or parting the roots in the early autumn, and 

 planting them out where the plants are to grow. 

 It succeeds best in a moist soil, and requires no 

 trouble but being kept free from weeds, by dig- 

 uing the ground about it in the winter. When 

 The stems" are destroyed in severe frosts, new 

 ones are put forth in the ensuing spring. 



The second sort is easily increased by plant- 

 ing cuttings of the voung shoots, in pots of rich 

 loamy earth, in the spring, plunging them in a 

 mode'rate hot-bed. 'When they have stricken 

 good root, they should be removed with balls of 

 earth about their roots into separate pots, and 

 be placed in the green-house. 



Though this plant is capable of standing the 

 open air-in mild winters, in warm dry situations, 

 it does not flower so well as in the green-house. 

 Superfluous plants should therefore only be em- 

 ployed in this way. 



These are ornamental plants ; the former in 

 the fronts of the clumps and borders, and the 

 latter among green-house collections and other 

 potted plants," where it produces a line appear- 

 ance. 



HYDRASTIS, a genus affording a hardy 

 perennial plant. 



It belongs to the class and order Pohjandria 

 Polygyria, and ranks in the natural order of 

 Ranumulacecc. 



The characters are: that there is no calyx : 

 the corolla has three petals, ovate, regular : the 

 stamina have numerous filaments, linear, com- 

 pressed, a little shorter than the corolla: anthers 

 compressed, blunt: the pistillum has numerous 

 germs, ovate, collected into an ovate head: 

 styles very short : stigmas broadish, compress- 

 ed : the pcricarpium is a berry, compounded of 

 oblong acini, or granulations : seeds solitary, 

 oblong. 



The species is H. Canadensis, Canadian 

 Yellow-root. 



It has the root composed of thick fleshy tu- 

 bers, of a deep vellow colour within, but cover- 

 ed by a brown skin, sending out fibres from se- 

 veral parts in the spring : it sends up one or 

 two stalks about nine inches high, at their first 

 appearance of a light green, but afterwards 



changing to a purplish colour, and hairy towards 

 the top. Each stalk has one or two leaves, the 

 lower peiiolcd, but the upper embracing ; they 

 are six or seven inches in diameter, and are 

 deeply cut into three, four, or five lobes, which 

 are irregularly serrate; they are of a light green 

 in the spring, but ch. age afterwards to a deep 

 green, with some dark spots or marks, and after 

 the flower is decayed turn to a purplish colour. 

 The stalk is terminated by one flower, which is 

 white, and of very short duration, seldom con- 

 tinuing above three or four hours after it is ex- 

 panded. The fruit is red and succulent. It is 

 a native of Canada, flowering in May and 

 June. 



Culture. — This plant may be increased by 

 sowing the seed, as soon as the fruit is well ri- 

 pened, in pots of pretty strong earth, protecting 

 thein from frost during the winter, and in the 

 spring, when the plants appear, setting them in 

 a shady situation till the autumn, when they 

 mnv be planted where they are to remain. 



It succeeds best in a moist shady situation, 

 where it is not disturbed. 



These plants serve to afford variety in such 

 situations. 



HYMENiEA, a genus containing a plant of 

 the stove exotic kind. 



It belongs to the class and order Deca?idria 

 Monogynia, and ranks in the natural order of 

 Lomentacece. 



The characters are: that the calyx is a one- 

 leafed perianthium, coriaceous i tube short, 

 turbinate, compressed, permanent, with an ob- 

 lique mouth : limb five-parted, almost regular, 

 upright, deciduous : segments ovate, blunt : two 

 opposite flattish, a little broader: two others 

 concave, with one side narrower: the corolla 

 five-petalled, inserted into the neck of the ca- 

 lyx, sub-papilionaceous, with the petals almost 

 equal : banner, the two uppermost petals, ob- 

 liquely ovate, obtuse, sessde, at the upper con- 

 cave segment of the calyx : wings, two petals, 

 similar^ lateral, a little narrower : keel, the low- 

 est petal, channelled and excavated, approxi- 

 mating to the wings, within the lower hollow 

 segment of the calyx: the stamina have ten 

 distinct filaments, awl-shaped, erect, bent down 

 above the middle, very long, between the keel 

 and the wings, inserted into the neck of the ca- 

 lyx : anthers linear, fixed by the back : the pis- 

 tillum is a germ, sabre-shaped, compressed, pe- 

 dicelled : style very long, bristle-shaped, bent 

 down : stigma thickened, obliquely truncate : 

 the pericarpium is a woody legume, very large, 

 ovate-oblong, obtuse, one-celTcd, filled with fa- 

 rinaceous pulp: the seeds several (four to eigh'l, 

 large), ovate, wrapped up in pollen and fibres;
