in dry weather. They are increased by off-sets 

 from the roots, which should be planted out in 

 the autumn. 



The first two sorts afford variety in the stove, 

 and the latter sorts in this as well as the borders. 



TACAMAHACA. See Populus. 



TAGETES, a genus furnishing plants of the 

 herbaceous annual kind. 



It belongs to the class and order Syvgene.'ia 

 Polygamia Svperflua, and ranks in the natural 

 order of Composit(B OpposilifelicE. 



The characters are : that the calvx is com- 

 mon, quite simple, one-leafed, tubular, oblong, 

 five-cornered, five-toothed : the corolla com- 

 pound radiate : corolleis hermaphrodite, tubu- 

 lar, many, on an elevated disk : fem.iles llgular, 

 five, in the ray : — proper in the hermaphrodites, 

 tubular, half-five-clctt, erect, longer than the 

 calyx, segnients linear, inwardly villose: — in 

 the females ligular, longer than in the her- 

 maphrodites, almost equal in length and breadth, 

 very blunt, narrower towards the tube, tomen- 

 tose, permanent : — the stamina in the hermaphro- 

 dites : filaments five, capillary, very short : an- 

 ther cylindrical, tubular: the pistillum in the 

 hermaphrodites : germ oblong : style filiform, 

 length of the stamens : stigma bifid, slender, 

 reflexed : — in the females germ oblong: style 

 filiform, length of the hermaphrodite: stigma 

 bifid, slender, reflexed: there is no pericarpium: 

 calyx unchanged : the seeds in the hermaphro- 

 dites solitary, linear, compressed, a little shorter 

 than the calyx : down with five, erect, acumi- 

 nate, unequal chafis. — In the females like the 

 others : tlic receptacle naked, small, flat. 



The species cultivated are : \. T. patula, 

 French Marygold : 2. T. erecta, African Mary- 

 gold. 



The first has the stem a foot and half high, 

 almost upright, smooth, diffused: the leaves 

 deeply piiniatilid, (pinnate with a winged rachis) 

 the segments lanceolate, serrate smooth, dark- 

 green, paler at the back, and punched : the 

 flowers solitary, terminating, gold- coloured, on 

 a long upright peduncle. It is probably a na- 

 tive of Mexico, flowering from July to autumn. 



There are several varieties : as the pale yellow- 

 flowered, deep vellow-flowered, golden yellow- 

 flowered, crimson-coloured, velvety, variegated 

 crimson and yellow, striped crimson and yellow ; 

 each of which has both single and double flowers. 



The second species has the stem three or four 

 feet high, straight, round, green, dividingfrom 

 the middle into many branches, each bearing 

 one large llower : the leaves^ long, pinnate ; leaf- 

 lets dark-green : the flowers yellow, from brim- 

 stone to orange colour, his a native of Mexico, 



There are varieties : as with pale-yclow or 



brimstone-coloured flowers, with deep yellow 

 flowers, with orange-coloured flowers ; each 

 with single, double, and fistulous flowers; the 

 middling African, with orange-coloured flowers, 

 and the sweet-scented African. 



Culture. — These plants are increased by seeds, 

 which should be sown in the beginning of 

 April upon a hot-bed, and when the plants ap- 

 pear, they should have plenty of fresh air, and 

 after they have attained some growth be trans- 

 planted on to another hot-bed, which is arched 

 over by hoops, at the distance of six inches, 

 watering and shading them well till fresh rooted, 

 being afterward graduallv inured to the open 

 air ; and about the beginning of May they may 

 be taken up with balls of earth about their roots,, 

 and planted in pots, to be set out in the courts, 

 yards, &c., about the house, shading them till 

 fresh rooted, and giving them water occa- 

 sionally : but the first sort divides and spreads 

 out widely near the ground, in a rambling man- 

 ner, and requires to be trimmed up at bot- 

 tom to a single stem, and its branches occa- 

 sionally, to preserve the head somewhat regular,, 

 and u iihin due bounds. 



The second species in particular, and the va- 

 rieties, as they always grow firmly erect, both 

 in stem and branches, require but very little 

 trouble after their final planting out: they afford- 

 ornament and variety among other plants, in 

 the borders, clumps, and other parts of pleasure- 

 grounds, as well as in pots for particular places 

 about the house, among other potted annual 

 plants. The seeils of each species, and their 

 varieties, should be annually saved from the 

 best plants. 



TALLOW TREE. See Ckoto-n. 



TAMAHfNDlJS, a genus containing a plant 

 of the exotic tree kind. 



It belongs to the class and order MonadeJphia 

 Triandria, {Triandria IMonogynia,) and ranks 

 in the natural order of Lomentacece. 



The characters are : that the calyx- is a one- 

 leafed perianth ; tube turbinate, compressed, 

 attenuated below, permanent ; mouth oblique ; 

 border four-parted, deciduous; segments ovate, 

 acute, flattish, reflexed, coloured ; the upper 

 and lower a little wider: the corolla has three 

 petals, ovate, concave, acute, crenate, waved, 

 reflexed, length of the calyx, inserted into the 

 mouth of the lube, the two lateral ones a Itttfe 

 larger : the stamina have three filaments, in- 

 serted into the orifice of the calyx at the void 

 sinus, length of the corolla, awl-shaped, united 

 below up to the middle, bowed towards the co- 

 rolla : anthers ovate, incumbent, large : threads 

 five (rudiments of stamens), alternate with the 

 filaments, and united below, but separate above,,-
