which they are laved in the tan-bed ; when they 

 will probably be well rooted in one year, though 

 it is sometimes two before they strike good root, 

 when they should be potted off into separate pots 

 and managed as the others. 



The last sort is best raised in this way. 



The cuttings of some of the short young 

 shoots should be made from such of the plants as 

 afford them, planting them in pots of fresh com- 

 post in July, plunging them in the bark-bed, 

 and covering them close with a low hand glass, 

 giving due water. 



They mostly take good root the same year, and 

 are fit to plant out in separate small pots in the 

 following spring. 



The general "management of these sorts is 



NAP 



only that of keeping them always in the stove, 

 except a month in the heat of summer, when 

 they may be set out in the open air. They 

 should he suffered to shoot nearly in their own 

 way, keeping them, however, to upright stems, 

 and allowing their heads to branch out accord- 

 ing to nature, except just reducing the very ir- 

 regular branches, giving frequent waterings in 

 common with other woody plants of the same 

 kind, and shifting them occasionally into larger 

 pots. 



The first sort and varieties are highly orna- 

 mental plants for the borders and green-house, 

 and the other tender sorts in the stove col- 

 lections.

NAP 



APiEA, a genus containing plants of 

 the hardy herbaceous flowery perennial 



It belongs to the class and order Dioecia 

 Monadelphia (Monadelphia PolyandriaJ , and 

 ranks in the natural order of Columniferce. 



The characters are : that in the male the calyx 

 is a bell-shaped five-cleft perianthium, round, 

 permanent : the corolla has five oblong petals, 

 concave, patulous, convex with oblong claws : 

 the stamina have very many capillary filaments, 

 of a middling length, connected in a column : 

 anthers roundish, compressed: the pistillum is a 

 conical germ, minute : style cylindric, ten-cleft, 

 capillary: stigmas none: the pericarpium abor- 

 tient : female on a distinct individual : the calyx 

 and corolla as in the male : the stamina have 

 filaments as in the male, but shorter : anthers 

 small, effete : the pistillum is a conical germ ": 

 style as in the male, longer than the stamens : 

 stigmas blunt : the pericarpium has ten capsules, 

 converging into anovate form, sharpish, awnless : 

 the seeds are solitary, and kidney-form. 



The species cultivated are: 1. N. Icevis, 

 Smooth NapEea ; 2. N. scabra, Rough Napa:a. 



The first has a perennial root, frequently 

 creeping : the stems smooth, about four feet 

 high : The leaves alternate, upon pretty long 

 slender foot-stalks, deeply cut into three lobes, 

 which end in acute points, and arc regularly 

 serrate ; those on the lower part of the stem are 

 mar four inches long, snd almost as much in

breadth, but they diminish gradually to the top 

 of the stem. At the base of the leaf comes out 

 the peduncle, about three inches long, dividing 

 at top into three smaller, each sustaining one 

 white flower, smaller than in the second sort, with 

 a longer column of stamens, the anthers stand- 

 ing out beyond the corolla. It is a native of 

 Virginia. 



The second has also a perennial root, com- 

 posed of many thick fleshy fibres, striking deep 

 into the ground, and connected at the top into 

 a large head, from which come out many rough 

 hairv leaves, near a foot diameter each way, 

 deeply cut into six or seven lobes, irregularly in- 

 dented on their edges, each lobe having a strong 

 midrib, all meeting at the foot-stalk, which is 

 large and long, arising immediately from the 

 root : the flower-stalks seven or eight feet high, 

 dividing into smaller branches, having one leaf at 

 each joint, of the same form as those below, but 

 diminishing in size towards the top, where they 

 seldom have more than three lobes, which are 

 divided to the foot-stalk. Towards the upper 

 part of the stalk comes out from the side at each 

 joint a long peduncle, branching out towards the 

 top, and sustaining several white flowers, which 

 are tubulous at bottom where the segments of 

 the petal are connected, but spread open above, 

 and are divided into five, obtuse segments : the 

 male plants are barren ; but in the female plants 

 the flowers are succeeded by ten capsules, placed 

 in a ring, semicircular, finishing at top in a re-
