CON 



'The Tricolor or Minor Convolvulus may 

 either be suffered to trail upon the ground, ac- 

 cording to its natural growth, or tied up to sticks : 

 but the other annual species and varieties, being 

 or the twining or running kind, should have tall 

 sticks to climb upon, on which they will rise 

 several feet in height, flowering all the way, and 

 appearing highly ornamental. 



The perennial sorts are elegant plants for the 

 greenhouse collection, and deserve the attention 

 of those who can preserve them during the win- 

 ter season. 



The last species may be raised by planting the 

 roots, either whole or divided, in a warm oor- 

 der, in the early spring months, where they will 

 send up stalks, and flower in the autumn ; but 

 to have them in greater perfection, they should 

 be planted in a slender hot-bed, covered with 

 a frame and glasses during bad weather, by which 

 means they flower earlier, and often form many 

 tubers at the joints. They are chiefly planted 

 for the sake of variety. 



CONYZA, a genus containing a plant of the 

 shrubby sort for the greenhouse. 



It belongs to the class and order Syngenesia 

 Poly gamin Svperflua, and ranks in the natural 

 order of Compositce Discoidece. 



The characters are : that the calyx is common, 

 imbricate, roundish, squarrose : scales acute, the 

 outer somewhat spreading : the corolla com- 

 pound tubulose : corollets hermaphrodite nu- 

 merous, tubular in the disk : females apetalous, 

 roundish in the circuit : proper, of the herma- 

 prodite funnel form : border five-cleft, patulous : 

 of the females, funnel-form : border three-cleft : 

 the stamina in the hermaphrodites, filaments five, 

 capillary, very short : anther cylindric, tubular: 

 pistillum in the hermaphrodites, an oblong germ : 

 style filiform, length of the stamens: stigma 

 two-cleft : in the females, germ oblong : style 

 filiform, length of the hermaphrodite, more slen- 

 der : stigmas two, very slender : there is no pe- 

 ricarpium, calyx converging : the seeds to the 

 hermaphrodites solitary, oblong; down simple : 

 to the females, solitary, oblong ; down simple : 

 the receptacle flat. 



The species mostly cultivated is C. candi- 

 da, White-leaved or Woollv Flea-bane. 



There are other species that may be cultivated 

 when variety is wanted. 



It has the stem suffruticose, six inches high, 

 upright, round, hairy, whitish, and branched : 

 the leaves are very white, quite entire, altemaic ; 

 the flowers purple, peduncled, heaped. Accord- 

 ing to Miller, the peduncles are woolly, nine 

 inches high, one-, two-, or three-flowered; the 

 flowers of a dirty yellow. It has a pleasant smell. 

 It is a native of Candia. 



COP 



Culture. — It may be increased by planting 

 slips 'or cuttings in separate pots of good earth, 

 the former in the spring, and the latter in the 

 summer months, plunging them firs! in a hot- 

 bed, and giving water pretty freely till they 

 have stricken root in both methods. 



These plants musthave thepiotectionof a good 

 garden frame or greenhouse during the winter. 



They afford an agreeable variety from the 

 silvery appearance of their leaves. 



COPAIFERA, a genus containing a plant of 

 the exotic balsamiferous kind. 



It belongs to the class and order Decandria 

 JSlonogyniu, and ranks in the natural order of 

 Leguminosce. 



The characters are: that there is no calyx : the 

 corolla has four petals, oblong, acute, concave, 

 very spreading: the stamina consist of ten fili- 

 form filaments, incurved, a little longer than 

 the corolla: anthers oblong, incumbent: the 

 pistillum is a round, compressed-flat, pedicelled 

 germ : style filiform, incurvate, length of the 

 stamens : stigma obtuse : the pericarpium is an 

 ovate, bivalve legume, pointed with part of the 

 style : the seed single, ovate, involved by a ber- 

 ried aril. 



The species is C. officinalis, Balsam of Capevi 

 Tree. 



In its native situation it is a lofty ele- 

 gant tree, with a handsome head: the extreme 

 branches at the axils are flexuose, and have a 

 smoothish bark of a brownish ash colour. The 

 leaves are alternate, pinnate, the midrib or rachis 

 round, and four inches long : leaflets three or 

 four pairs, without an odd one, lanceolate-ovate, 

 ending in a blunt point, quite entire, shining, 

 subcoriaceous, with several obliquely- ascending 

 veins, the middle nerve prominent beneath, 

 and ferruginous ; they are from two to three 

 inches long, and on short petioles ; the inner 

 ones are narrower by half than the others ; 

 the two uppermost opposite, but one of these 

 frequently wanting, so that the leaf then ap- 

 pears to be unequally pinnate; the rest are al- 

 ternate. The flowers are white, sitting closely on 

 the peduncles. It is a native of South America. 



It is the tree which aftords, by perforating the 

 trunk, the fluid balsam or resin which thickens 

 by degrees, and is entitled "Balsam of Capevi." 



Culture. — It may be increased by sowing 

 the seeds procured from America, or the West 

 Indies, on a bark hot-bed ; and when the plants 

 are of a proper size, they should be potted and 

 placed in the bark-bed of the stove, and treated 

 as other plants of the exotic woodv kind. It 

 may likewise be raised from cuttings of the young 

 shoots planted in the spring season in pots, 

 plunging them into the hot-bed.
