LAM 



THE UNIVERSAL HERBAL; 



LAM 



those of Honeywort. The flowers which appear in June 

 and Juiy, are collected into spherical heads at the extre- 

 mity of ihe stalks, and are of a greenish-yellow colour. 

 Native of the Levant. Sow the seeds in autumn on a warm 

 border soon after they are ripe; or if they be permitted to 

 scatter, they will soon come up of themselves. When the 

 seeds are sown in the spring, they commonly remain in the 

 ground a year, and sometimes two or three, before they grow. 

 LagiiMEa ; a genus of the class Monadelphia, order Poly- 

 andria. GENERIC CHARACTER. Calix : perianth one- 

 leafed, bell-shaped, somewhat cornered, half five-cleft, per- 

 manent (according to Cavanilles, deciduous.) Corolla: petals 

 five, ovate-oblong, obtuse, spreading, affixed to the base of 

 the tube of the stamina. Stamina: filamenta several, (from 

 twenty-five to thirty,) conjoined into a tube below, in the 

 top and sides of the tube receding from it and free ; antherce 

 roundish. Pistil: germen ovate-oblong; style thread-shaped, 

 longer than the stamina, five-cleft at the tip: divisions spread- 

 ing, or undivided; stigmas headed. Pericarp: capsule 

 ovate-oblong, somewhat five-cornered, five-celled, five-valved ; 

 partitions contrary. Seeds: some, roundish, three-sided. 

 ESSENTIAL CHARACTER. Calix: simple, five-cusped. 

 Style: simple. Stigma : peltated. Capsule : five-celled, five- 

 valved. Plants of this genus may be propagated and culti- 

 vated in the same manner with those species of Hibiscus which 

 come from hot countries ; which see. The species are, 



1. Lagunaea Aculeata ; Prickly Lagunata. Stem prickly, 

 tomentose ; leaves deeply many-parted ; flowers axillary, soli- 

 tary. Flowers on short peduncles ; corolla yellow, twice as 

 long as the calix, spreading. Native of Coromandel, near 

 Pondicherry, where it is called cattacacheree by the natives. 



2. Lagunsea Solandra; Maple-leaved Laguneea. Leaves 

 subcordate, three-cusped, serrate ; flowers corymbed. This 

 plant is about two feet high, and hirsute; stem upright, 

 round, stiff, the thickness of a goose-quill ; flowers corymb- 

 racemed at the ends of the stem and branches; corolla pur- 

 plish white. Found in the Isle of Bourbon. See Hibiscus 

 Solandra, which is the same plant. It ripens seed in Eng- 

 land, and may be increased by them. 



3. Lagunsea Ternata ; Three-leaved Laijuncea. Stem her- 

 baceous, villose; lower leaves ternate, with the middle leaflet 

 very long; upper leaves subhastate; flowers axillary, solitary. 

 Root round, not very fibrous. Native of Senegal. 



Lagurus; (Hare's-tail Grass) a genus of the class Triandria, 

 order Digynia. GENERIC CHARACTER. Calix: glume 

 one-flowered, bivalve ; valves long, linear, spreading, very thin, 

 each en'ding in a villose awn. Corolla: bivalve, thicker than 

 the calix ; valve exterior, longer, terminated by two small up- 

 right awns; a third awn from the middle cf the back of the 

 same valve, reflex-twisted; valve interior, small, sharp; nectary 

 two-leaved; leaflets lanceolate, obtuse, gibbous at the base. 

 Stamina: filamenta three, capillary ; antheraj oblong. Pis- 

 til: germen top-shaped; styles two, setaceous, villose; stig- 

 mas simple. Pericarp: none. Corolla: grows to the seed. 

 Seed: solitary, oblong, covered, awned. ESSENTIAL CHA- 

 RACTER. Calix: two-valved, with a villose awn. Corolla: 

 having on the outer petal two terminating awns, and a third 

 dorsal one, twisted back The only species is, 



1. Lagurus Ovatus. This is an annual grass, growing to 

 the height of a foot or eighteen inches, and even more, very 

 soft and hoary, as are also the leaves and spikes. Native of 

 the south of Europe, France, Italy, Sicily, and Portugal. 



Lamb's Lettuce. See Valeriana. 



Lambertia ; a genus of the class Tetrandria, order Mono- 

 jryniu. GENERIC CHARACTER. Calix: involucre of many 

 long, imbricated, coloured leaves, the inner ones graduaily the 



largest, containing from one to seven flowers, deciduous ; 

 perianth none. Corolla: petals four, cohering at the base, 

 linear-lanceolate, equal, revolute from above their point of 

 union, bearing the stamina; nectary of four glandular scales 

 at the base of the germen, sometimes united. Stamina : fila- 

 menta none ; antherae four, sessile at the inner side of the 

 revolnte part of each petal, linear, at length recurved. Pis- 

 til : germen superior, turbinate, fringed at the top; style 

 thread-shaped; stigma rather thicker, prominent, awl-shaped, 

 furrowed. Pericarp : follicle roundish-wedge-shaped, some- 

 what woody, more or less horned or tubercular, of one cell. 

 Seeds: two, orbicular, compressed, each encompassed with 

 a rounded ring; common receptacle flat, without scales. ES- 

 SENTIAL CHARACTER. Petals: four, cohering, spirally 

 revolute, bearing the stamina. Nectary: of four scale*. 

 Stigma: awl-shaped. Follicle: woody. Seeds: two, bor- 

 dere^l. Involucre: of many leaves, imbricated, coloured, 

 deciduous. Receptacle: flat. The species are, 



1. Lambertia Uniflora. Flowers solitary in each involucre. 

 Leaves obovate, with a point, smooth, reticulated. Follicle 

 pointed at one side, without horns. Gathered by Mr. Brown 

 in Lewin's Land, on the south coast of New Holland, growing 

 about rocky inlets near the shore 



2. Lambertia Inermis. Flowers seven in each involucrum; 

 twice as long as its inner leaves ; styles smooth ; follicles 

 pointed at one side, without horns ; leaves oblanceolate or 

 obovate, pointless. Native of stony hills in Lewin's Land. 



3. Lambertia Formosa. Flowers seven, in each involucre, 

 the length of its inner leaves ; style hairy ; follicle pointed at 

 one side, two-horned at the other; leaves linear-lanceolate, 

 sharp-pointed, recurved at the edges. Involucre and flowers 

 of a fine rose-colour or crimson. The leaves are green and 

 smooth above ; white, and reticulated with veins beneath. 

 Native of stony heaths near Port Jackson. 



4. Lambertia Echinata. Leaves linear, smooth, reticu- 

 lated ; dilated, lobed, and pointed at their extremities; fol- 

 licles two-horned, thorny all over. Native of stony sides of 

 hills in Lewin's Land. Not being seen in flower, its genus 

 remains doubtful. 



Lamium ; a genus of the class Didynamia, order Gymno- 

 spermia. GENERIC CHARACTER. Calix: perianth one- 

 leafed, tubular, wider above, five-toothed, awned, nearly 

 equal, permanent. Corolla: one-petalled, ringent ; tube 

 cylindric, very short; border gaping; throat inflated, com- 

 pressed, gibbous, marked on each edge with a reflex tooth- 

 let; upper lip arched, roundish, obtuse, entire; lower lip 

 shorter, obcordate, emarginate, reflex. Stamina: filamenta 

 four, awl-shaped, covered beneath the upper lip, two of 

 them longer; anthera oblong, hairy. Pistil: germen four- 

 cleft; style filiform, length and situation of the stamina; 

 stigma two-cleft, sharp. Pericarp: none. Calix: open, and 

 bearing in its bosom the seeds, which are flat at top. Seeds: 

 four, short, three-sided, convex on one side, truncated on 

 both sides. ESSENTIAL CHARACTER. Corolla: upper lip 

 entire, vaulted; lower two-lobed ; throat with a reflex tooth- 

 let on each side. The species are, 



1. Lamium Orvala; Baum-leaved Archangel. Leaves 

 cordate, unequally and sharply serrate; corollas inflated at 

 the throat; calix coloured. Hoot perennial ; stem from half 

 a yard to nearly a yard high ; corolla an inch long, of a deep 

 red colour. The brilliance and size of the flowers have 

 secured it admittance into the garden, while all the rest are 

 excluded, notwithstanding its strong and unpleasant smell. 

 The Orvala Garganica of Linneus is a mere variety of this, 

 owing its apparent difference to having grown in a moist 

 shady place. Native of Italy, Silesia, and Hungary. Jt
