among them, they will soon overbear the plants while they 

 are young. Let them remain in this seed-border until the 

 following Michaelmas, when they should be carefully taken 

 up, and transplanted wherever they are intended to be fixed. 

 Some ought to be reserved in pcjs to be sheltered in winter, 

 when all those in the full ground are sometimes destroyed 

 by the severe frosts. They may also be increased by parting 

 the roots in the spring, just before the plants begin to shoot, 

 which is commonly about the middle or end of March ; but, 

 in doing this, the roots must not be parted too small, for that 

 will prevent their flowering strong. They perfect their seeds 

 in this country every year : the seedlings will not flower until 

 the third year. 



3. Triosteum Triflorum. Peduncles opposite, three-flow- 

 ered ; leaves petioled. Stem erect, a foot and half high,

 pressed close, scarcely half an inch long; flowers sessile. 

 Supposed to be a native of Madagascar.

 with the margins thinner, (the exterior one straightish,) em- 

 bracing the interior, oblong, triangular, boat-shaped, acute,

 two-valved, membranaceons, very thin, awnless, less than the 

 calix ; valves nearly equal ; exterior ovate, boat-shaped,

 cate, mucronate at both ends, the upper margin thinner, the 

 middle emarginate. Stamina: of the outer floret; filamenta 

 three, capillary, longer than the calix; antherse parallele- 

 piped : of the inner floret ; filamenta three, very slender, sub- 

 connate ; antherse none. Female Flowers, on the same spike 

 below the males, immersed alternately on each side into the 

 rachis. Calix: involucre ovate, cartilaginous, very thick, 

 ventricose below, shining, obscurely margined on both sides 

 at the back, subemarginate, with a blunt top, embracing the 

 glume with its thinner margin; glume two-valved; outer 

 valve oblong, ventricose, attenuated at the top, acuminate, 



thickish, doubled ; inner similar, bluntish. Corolla : two- 

 valved, smaller than the calix, and more tender; outer valve 

 larger, ventricose, bluntly three-toothed ; inner scarcely 

 smaller, flat at the back, emarginate : abortive glume one- 

 valved, oblong, folded together at each margin, two-toothed, 

 by the anterior side of the fertile corollet, and much smaller 

 than it. Nectary two-leaved, very small ; leaflets linear, 

 membranaceous, very thin, acutely emarginate at the top. 

 Stamina: filamenta three, at the base of the germen, very 

 small, broad at the base, capillary ; antherse linear, very 

 small, barren. Pistil: germen oblong; style longer than 

 the calix, compressed ; stigmas two, very long, twisted, vil- 

 lose. Pericarp: none. Seed: one, ovate, compressed a 

 little, pointed with the permanent style. Observe. At the 

 base of the involucre, on each side, is a sinus gaping exter- 

 nally, with an aperture blocked up by villose hairs. ESSEN- 

 TIAL CHARACTER. Male. Calix: glume two-flowered. 

 Corolla: valves membranaceous. Female. Calix: glume 

 with perforated sinuses. Corolla: two-valved. Stigmas: 

 two. Seed: one. The species are, 



1. Tripsacum Dactyloides. Spikes androgynous. Leaves 

 long, linear, taper-pointed, an inch broad, smooth; culms 

 the thickness of a goose-quill or of the little finger, with few 

 joints and long internodes, angular, tinged with purple, as 

 high as a man, dividing at top into three, four, or five spikes, 

 a long span or a foot in length, and straight. It flowers in 

 August, and is a native of Virginia. It is a hardy perennial.

1. Triticum jEstivum; Summer or Spring Wheat. Calix 

 four-flowered, tumid, smooth, imbricated, awned. This is 

 suspected to be a mere variety of the following species ; and, 

 if sown in the spring, will produce a speedy but uncertain 

 crop. This sort of Wheat is supposed, and with great pro- 

 bability, to have been originally produced in Sicily, where it 

 is known under the name of Tumenia, a corruption of Tri- 

 menia, or Three-months Grain. It is much cultivated in 

 Barbary, Spain, Portugal, France, Germany, and in most
