longer than the flowers. It very much resembles an Aspho- 

 del, but has three recurved styles. Native of Pennsylvania 

 and Virginia. It flowers in May and June. 



3. Helonias Pumila. Radical leaves obovate, those on the 

 stem lanceolate; cluster cylindrical; flowers with narrow white 

 petals and yellow antherae. Native of Virginia, Canada, &c. 



Helvetia; a genus of the class Cryptogamia, order Fungi. 

 GENERIC CHARACTER. Pilens on the stem smooth on 

 both sides; seeds thrown out from under the surface. Per- 

 soon enumerates nine species ; one without a stalk ; three 

 with a furrowed stalk ; and five with a smooth or even one. 

 The following are of each section. 



1. Helvella Acaulis. Sessile, waved, expanded, reddish- 

 brown, paler and fibrous underneath. Found in the ground 

 in Fir forests. 



2. Helvella Mitra. Pileus tumid, many-lobed, of a black- 

 ish livid hue; stalk furrowed and cellular, whitish. Common, 

 growing on the ground, and is, like the Morel, eatable. 



3. Helvella Esculenta. Stalk smooth ; pileus reddish- 

 brown, roundish, its surface crumpled and cellular. This is 

 often confounded with the true Morel. 



Hemerocallis ; a genus of the class Hexandria, order Mo- 

 nogynia. GENERIC CHARACTER. Calix: none. Corolla: 

 six-parted, bell-funnel-form; tube short ; border equal, spread- 

 ing, more reflex at top. Stamina : filamenta six, subulate, 

 the length of the corolla, declining, upper ones shorter ; an- 

 theree oblong, incumbent, rising. Pistil: germen roundish, 

 furrowed, superior; style filiform, the length and situation of 

 the stamina; stigma obtusely three-cornered, rising. Peri- 

 carp: capsule ovate, three-lobed, three-cornered, three- 

 celled, three-valved. Seeds : very many, roundish. ESSEN- 

 TIAL CHARACTER. Corolla : bell-shaped, the tube cylindric. 

 Stamina: declining. The species are, 



1. Hemerocallis Flava; Yellow Day Lily. Leaves linear- 

 subulate, keeled ; corollas yellow. It has strong fibrous roots, 

 to which hsng knobs or tubers, like those of the Asphodel, 

 from which come out leaves two feet long, with a rigid midrib, 

 the two sides drawing inward, so as to form a sort of gutter 

 on the upper side : the flower-stalks rise two feet and a half 

 high, having two or three longitudinal furrows ; these are 

 naked, and at the top divide into three or four short peduncles, 

 each sustaining one pretty large yellow flower, shaped like a 

 Lily, having but one petal, with a short tube, spreading open 

 at the brim, where it is divided into six parts : they have an 

 agreeable scent, from which some have given this plant the 

 title of Yellow Tuberose. It flowers in June, and the seeds 

 ripen in August. There is a variety with smaller roots and 

 leaves : both are natives of Siberia, Hungary, Dalmatia, Istria, 

 and has found its way into Switzerland and Silesia. This, 

 and the other species, are easily propagated by offsets, which 

 the roots send out in plenty; they may be taken off in autumn, 

 (that being the best season for transplanting the roots,) and 

 planted in any situation, for they are extremely hardy, and 

 will require no culture but weeding, and room sufficient to 

 spread their roots. The first species may also be propagated 

 by seeds, which, if sown in autumn, the plants will come up 

 in the following spring, and these will flower in two years ; 

 but if the seeds are not sown till spring, the plants will not 

 come up till the year after. In a moist soil and shady situ- 

 ation they thrive better than in dry ground. 



2. Hemerocallis Fulva; Copper-coloured Day Lily. Leaves 

 linear-subulate, keeled ; corollas tawny or copper-coloured. 

 This is a much larger plant than the first, and the roots 

 spread and increase much more; the flower-stalks are as 

 thick as a man's finger, and rise nearly four feet high ; they 

 are naked, without joints, and branching at the top, where 



there are several copper-coloured flowers, shaped like those of 

 the Red Lily, and as large. The stamina are longer than those 

 of the preceding species, and their summits are charged with 

 a copper-coloured farina, which sheds on being touched. 

 The flowers appear in July and August, p.nd only last each 

 one day, though there is a succession on the same plant for a 

 fortnight or three weeks. Native place of growth uncertain. 

 In Japan i* varies with a double flower; and in China and 

 Cochin-china the inhabitants boil the flowers, both fresh and 

 dry, commonly with their meat. It is a very unsuitable plant 

 for small gardens, and best adapted for plantations. 



3. Hemerocallis Lancifolia. Leaves lanceolate, seven- 

 nerved; scape round, jointed, upright, smooth, longer than 

 the leaves ; flowers at the top of the scape in racemes, droop- 

 ing; corolla white. Native of Japan, where it is frequently 

 kept in gardens and houses for its elegance ; flowering in 

 August and September. 



4. Hemerocallis Japonica. Leaves ovate, wavy, many- 

 nerved ; petioles winged, membranaceous, a hand in length 

 or rather more. Native of Japan. 



5. Hemerocallis Cordata. Leaves heart-shaped, veined ; 

 stem round, upright, smooth, a foot high or more; flowers ter- 

 minating, alternate, upright. Geertner doubts whether this be 

 a genuine species of Hemerocallis, since it differs so much in 

 the fruit. Native of Japan, where it is frequently cultivated. 



6. Hemerocallis Graminea; Narrow-leaved Day Lily. 

 Leaves channelled, nearly triangular ; bractes short and 

 membranous ; corolla swelling at the base, its inner segments 

 crisped at the base ; stigma three-lobed. Native of Siberia. 



Hemimeris ; a genus of the class Didynamia, order Angio- 

 spermia. GENERIC CHARACTER. Calix : perianth one- 

 leafed, five-parted almost to the base, much shorter than the 

 corolla; parts ovate, unequal, permanent. Corolla: mono- 

 petalous, wheel-shaped, ringent ; tube very short, (scarcely 

 any,) intruded, white ; upper lip cloven, with a kind of bag 

 at the base, composed of little nectareous pits ; lower concave, 

 blunt. Stamina : filamenta two or four, filiform, inserted 

 into the base of the lower lip, bent round ; antherae very 

 small, heart-form, cohering, yellow. Pistil: germen supe- 

 rior, sharp, smooth ; style thread-form, of the same length 

 and in the same situation with the stamina; stigma simple, 

 sharpish. Pericarp : capsule ovate, sharp, twin, gibbous at 

 the base on one side, two-celled, two-valved. Seeds: very 

 many, smooth. Observe. Allied to Antirrhinum, but differ- 

 ing in the form of the corolla. ESSENTIAL CHARACTER. 

 Calix : five-parted. Corolla : wheel-form ; upper lip cloven, 

 with a nectareous bag at the base. The species are, 



1. Hemimeris Sabulosa. Diandrous : leaves opposite, pin- 

 natifid ; stem prostrate. Native of the Cape. 



2. Hemimeris Montana. Diandrous : leaves opposite, 

 ovate., serrate ; stem upright. Native of the Cape. 



3. Hemimeris Diffusa. Didynamous : leaves alternate and 

 opposite, pinnatifid ; stem patulous. Native of the Cape. 



Hemionitis, or Mule Fern ; a genus of the class Crypto- 

 gamia, order Filices or Ferns. GENERIC CHARACTER. 

 Capsules digested into lines, meeting together, either inter- 

 secting each other or branched. The species are, 



1. Hemionitis Lanceolata. Fronds lanceolate, quite entire; 

 leaves plane and simple, seldom exceeding sixteen or eighteen 

 inches in length, when most luxuriant ; they grow in tufts 

 from a strong fibrous root. This plant is commonly found 

 on the trunks of trees, in the cooler and more shady inland 

 woods of Jamaica. Neither this nor any of its genus is often 

 propagated in gardens. They must be all procured from the 

 country where they naturally grow; planted in pots filled 

 with loamy undunged earth, and placed in the stove : in
