The (irst is an annual plant, with an upright 

 stalk, having six angles, rising two or three 

 feet high, and dividing into many branches: 

 the leaves opposite, an inch and half long, and 

 one inch broad ; smooth, as are also the stalks : 

 at each joint come out clusters of small bractes : 

 long before the stalks decay, most of the leaves 

 fairoff", having only these bractes : the flowers 

 are in small spikes at the side of the branches, 

 sitting very close : they are of a beautiful car- 

 mine colour. It is a native of La Vera Cruz, 

 &c. 



The second species has a brittle stem, five or 

 six feet high, sending out many branches : the 

 leaves two inches long, and one inch broad, 

 hairv, opposite: the flowers large, of a carmine 

 colour, and ranged on one side of the spike. It 

 is a native of La Vera Cruz. 



The third has a roundish stem, compressed, 

 jointed : the leaves petioled, smooth, acuminate, 

 quite entire : the spike strobile-shaped, with 

 spreading, upright bractes : it grows five feet 

 hii'fh : the flowers grov/ in very long spikes from 

 the end of the branches, and are of a greenish 

 colour, with a shade of blue. It is a native of 

 the Flast Indies. 



The fourth species rises here with a strong 

 woody stem to the height of twelve or fourteen 

 feet, sending out many spreading branches : the 

 leaves more than six inches long, and three 

 inches broad, placed opposite: the flowers on 

 short spikes at the end of the branches. It 

 flowers in July, and is a native of Ceylon. 



The fifth has the stem from three to four feet 

 hioh, sending out branches on every side from 

 the bottom, so as to form a pyramid ; they are 

 covered with a white bark : the leaves entire, 

 near two inches long, and one third of an inch 

 broad, smooth, stiff, deep green, opposite: at 

 the base of the foot-stalks come out clusters of 

 smaller leaves, of the same shape and texture : 

 the peduncles short : the flowers white, with 

 long calyxes : the capsules oblong, ^vhen ripe 

 throwing out their seeds, whence the name of 

 Snap-tree. It is a native of the Canary islands. 



Culture. — Tliese plants may be increased, 

 some of them by seeds, and the others by layers 

 and cuttings ; but the latter modes are mostly 

 practised, as the seeds arc obtained with difli- 

 cullv. 



Where the seeds are capable of being pro- 

 cured, they may be sown in small pots filled 

 with light fresh earth, in the early spring, being 

 plunged in a Ijot-bed of b.irk, watering the 



mould of the pots moderately when it becomes- 

 dry. As they often remain long before the 

 plants appear, the pots should not be dis- 

 turbed, but be kept in the hot-bed. When the 

 plants appear, fresh air should be admitted in. 

 mild weather, and slight waterings given ; and 

 when they have attained a few inches in growth, • 

 they should be removed into separate pots filled 

 with freshearth, replunging them in thehot-bed, 

 watering and shading them till they have taken 

 fresh root; air being then freely admitted, and as 

 the season grows warm, due waterings being given. 

 As they advance in growth, they should be ? 

 placed in larger pots, taking care not to over- 

 pot them, keeping them constantly in the hot- 

 bed. 



The layers should be laid down in the early 

 spring, in pots filled with light earth, a little 

 water being given at the time. 



The cuttings may be made from the young 

 shoots, and planted in pots filled with the same 

 sort of earth in the later spring or summer 

 months, giving them a little water, and plun- 

 ging them in the hot-bed of bark in the stove, 

 due shade being given. 



When the plants have become perfectly root- 

 ed, they may be taken oif, or removed into se- 

 parate pots, keeping them constantly in the stove 

 or green-house, according as they are more or 

 less hardy. The two first sorts are the most 

 hardy ; the others succeeding best in the hot- 

 house or stove. 



The two first afford ornament and variety 

 among the other potted plants of the less tender 

 sorts, and the other among those of the stove 

 kinds. 



IVY. See Hedera. 



IXIA, a cenus containing plants of the her- 

 baceoas, bulbous, and tuberous root peren- 

 nial kind. 



It belongs to the class and order Triandria 

 Monogynia, and ranks in the natural order of 

 Ensatce. 



The characters are : that the calyx is a spathe, 

 bivalve, inferior, shorter than the corolla : 

 valves oblong, permanent, the exterior wider, 

 sheathing the interior : the corolla one-petalled, 

 regular, superior: tube filiform, gradually en- 

 larged, straight : border regular, bell-shaped, 

 six-parted : divisions oblong, obtuse, equal, 

 spreading : the stamina have three filaments, 

 thread-subulate, inserted into the tube near the 

 orifice, shorter than the corolla : anthers oblong, 

 funxn\ed: the pistillum is an inferior, triangu- 

 lar germ : style simple, filiform, upright : stig- 

 mas three, filiform : the pericarpium is an ovate 

 capsule, three-sided, obtuse, three-celled, ihrcc- 

 valved : the seeds several, roundish, smooth.
