which are seldom ripened in England. The best time to 

 plant the cuttings is in the spring, just before the plants 

 begin to shoot : they should be placed in p.ots of soft loamy 

 earth, and plunged into a very moderate hot-bed, covering 

 them close with a glass to exclude the air. They must be 

 shaded from the sun ; and have very little water after their 

 rust planting. If any of them grow, remove them into sepa- 

 rate small pots filled with loamy earth, and expose them to 

 the air in a sheltered situation till autumn, when they must 

 be removed into the g-reen-house, and treated in the same 

 manner as Oraiige-trees.

Kleinhojia ; a genus of the class Gynandria, order Decan- 

 dria, according to Linneus : but Schreber classes it under 

 Dodecandiia, order Monogynia. GENERIC CHARACTER. 

 Calix: perianth five : leaved; leaflets oblong, nearly equal; 

 the lower one rather shorter, deciduous. Corolla: petals 

 five, lanceolate, sessile, rather longer than the calix ; the 

 upper one shorter, wider, and arch-truncated ; nectary cen- 

 tral, seated on a column of the length of the calix, surrounded 

 at the base by glandules, ascending at the tip, bell-shaped, 

 very small, half five-cleft; divisions recurved. Stamina: 

 tilamenta fifteen, very small, three of them sitting on each 

 division of the nectary, two of them being terminal, the third 

 rather lower ; antlmnu twin. Pistil : germen in the hollow 

 of the nectary, ovate, five-cornered ; style simple ; stigma 

 somewhat crenated. Pericarp : capsule five-lobed, five-cor- 

 nered, ten-valved, inflated. Seeds: solitary, roundish, sub- 

 echinated. ESSENTIAL CHARACTER. Calix: five-leaved. 

 Corolla: five-petalled. Neclary : bell-shaped, peduncled, 



staminiferous. Capsule: inflated, five-lobed. The only 



known species is, 



1 . Kleinhofia Hospita. Leaves alternately scattered, longer 

 than the petioles; flowers in racemes, small, numerous, bright 

 purple ; trunk the height of a common apple-tree, thick, 

 incurved, and knobbed. The whole plant is smooth ; its 

 leaves, when bruised, especially the young cues, smell like 

 violets. Native of Java, Amboyna, and the Philippine Islands, 

 where it flowers frequently in the year, and has commonly 

 fruit on it, but most abundantly in October.

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

 gynia. GENERIC CHARACTER. Calix: perianth common, 

 containing the floscules disposed in a simple orb, simple, 

 cylindric, oblong, upright; divisions awl-shaped, approxi- 

 mated, of the number of the floscules ; perianth proper, very 

 small, crowning the germen, quite entire, coriaceous, per- 

 vious at top. Corolla: universal equal ; proper one-petalled, 

 unequal ; tube the length of the calix ; border unequal, 

 four-cleft, the exterior segment larger, ovate. Stamina fila- 

 menta four, longer than the tube of the corolla, inserted into 

 the receptacle ; antherse oblong, incumbent. Pistil: germen 

 inferior; style filiform, length of the stamina ; stigma thickish, 

 two-cleft. Pericarp: none. Seeds: solitary, four-sided, 

 crowned with the down, and covered with the proper invo- 

 lucre of the flower; receptacle common, scarcely remark- 

 able, flat, naked. Observe. This genus is distinguished 

 from Scabiosa by the tubulated calix, and the simple orbit 

 of flowers. ESSENTIAL CHARACTER. Calix: common, 

 oblong, simple, five to ten flowered; proper simple, supe- 

 rior. Corollcts: irregular. Receptacle: naked. The 



species are, 



1. Knautia Orientalis. Leaves gashed; corollets in fives, 

 longer than the calix. It rises with an upright, branching 

 stalk, four feet high; the branches terminated by single 

 peduncles, each supporting one flower, with the florets of a 



bright red colour. It is annual, and a native of the Levant. 

 This, and the other species also, are easily propagated. 

 If the seeds be permitted to scatter in the autumn, tlie plants 

 will come up soon after ; and if some of them be planted in 

 the borders of the pleasure-garden, or among low shrubs 

 near the walks in October, the plants will survive the winter, 

 and flower in June. 



2. Knautia Propontica. Upper leaves lanceolate, quite 

 entire ; corollets in tens, equal to the calix. Stem biennial, 

 the thickness of a finger, two feet high, villose. Observed 

 by Forskal in the Levant. 



3. Knautia Palaestina. Leaves entire, six-leaved ; seeds 

 pappose. Stem upright, straight, round, brachiate, some- 

 what hairy, scarcely a foot high ; leave opposite, hairy. It 

 is an annual plant. Native of Palestine. 



4. Knautia Plumosa. Upper leaves pinnate ; calices ten- 

 leaved ; seeds pappose. Stem upright, straight, round, 

 brachiate, pubescent, a foot and a half high ; corolla pale 

 blue. Native of the Levant.

Kttoxia ; a. genjs of the class Tetrandria, order Mono- 

 gynia. GENERIC CHARACTER. Calix: perianth four- 

 leaved, superior, small, deciduous ; leaflets sharp-pointed, 

 one lanceolate, thrice the size of the rest. Corolla : one- 

 petalled, funnel-form; tube filiform, long; border four- 

 parted; divisions equal, somewhat oblong, rounded. -Sta- 

 mina: filamenta- four, capillary, within the mouth of the 

 corolla; antherae oblong, equal. Pistil: germen roundish, 

 inferior; style filiform, length of the stamina; stigmas two- 

 headed. Pericarp: fruit naked, subglobose, sharp-pointed, 

 furrowed. Seeds: two, roundish, sharp-pointed, outwardly 

 convex, marked with three streaks ; inwardly flat, connected 

 at the upper part to a thread-form receptacle. ESSENTIAL 

 CHARACTER. Corolla: one-petalled, funnel-form. Seeds: 



two, grooved. Calix: one leaflet larger. The only known 



species is, 



1. Knoxia Zeylanica. This plant has the appearance of a 

 Plumbago, or a Lychnis. Stem upright, afoot high, smooth, 

 jointed ; leaves opposite, lanceolate, subsessile, veinless, 

 smooth; spikes long, narrow, with scattered sessile flowers.

 noecia. ESSENTIAL CHARACTER. Calix: five-leaved.

two seeds in each. The only known species is, 



1. Koelreuteria Paulinioides. Leaves equally pinnate, 

 with six pairs of leaflets, which ane ovato, laciniate, serrate,
