from warm countries, admitting a large share of free air to 

 them when the weather is warm ; at which time it must be 

 given with great caution, for too much wet will infallibly 

 destroy them; while the plants are young, they may be kept 

 during the summer season in a hot-bed of tanners' bark under 

 a frame; but in the autumn they must be removed into the 

 bark-stove and plunged into the hot-bed of tan, where they 

 should constantly remain, and must be treated in the same 

 manner as other tender plants, being careful not to give them 

 too much water in the winter, when it is very prejudicial to 

 them ; and in summer they should have a large share of free 

 air admitted to them every day. With this treatment the 

 plants will thrive very well ; but being plants of slow growth 

 in their own country, cannot be expected to make great pro- 

 gress in Europe. In their native country, they grow very 

 readily from seed , and seem fond of a dry soil with a hot 

 exposure. 



2. Guaiacum Sanctum ; Holy Guaiacum. Leaflets many 

 pairs, obtuse. It has many leaflets placed along the midrib 

 by pairs ; they are rounded and obtuse at their ends, but 

 narrow at their base, of the same consistence with those of 

 the first sort, but of a darker green colour. The flowers are 

 produced in loose bunches towards the ends of the branches, 

 are of a fine blue colour, and the petals are fringed on their 

 edges. This is called Bastard Lignum Vitce, in some of the 

 West India Islands. See the first species. 



3. Guaiacum Afrum. Leaflets many pairs, acute; branches 

 rigid ; leaves alternate, with eight pairs of leaflets ; stipules 

 pressed close to the branches, subulate, very small. Native 

 of Mossel-bay, near the Cape of Good Hope. This will live 

 in a good green-house all the winter, but in summer it must 

 be placed abroad with other green-house plants. It Is of a 

 slow growth, and is with difficulty propagated by layers. ' 



4. Guaiacum Dubium. Leaves conjugate, oblong, lanceo- 

 late, obtuse. Native of Tongatabu in the South Seas. 



Guarea; a genus of the class Octandria, order Monogynia. 

 GENERIC CHARACTER. Calix : perianth one-leafed, 

 four-parted, flattish, short. Corolla : petals four, spreading, 

 lanceolate, obtuse ; nectary tubular, cylindric, quite entire, 

 length of the corolla, contracted at the throat. Stamina : 

 filamenta none; antheree eight, growing to the inner edge of 

 the nectary, ovate. Pistil: germen roundish, on a very 

 short pedicel ; style subulate, thick, length of the nectary ; 

 stigma four-cornered, depressed. Pericarp: capsule round- 

 ish, large, subsessile, four-grooved, four-celled, four-valved. 

 Seeds : solitary, oblong, with a scarlet aril. Observe. It 

 should be distinguished from Trichilia, to which it is nearly 

 allied. ESSENTIAL CHARACTER. Calix : four-cleft. Pe- 

 tals: four. Nectary: cylindric, bearing the antheree at its 

 mouth. Capsule: four- celled, four-valved. Seeds: solitary. 

 The only known species is, 



1. Guarea Trichilioides; Ash-leaved Guarea. This is a 

 middling-sized tree, with a smooth trunk; racemes a foot 

 long, axillary, subdivided, loose; the branches many-flow- 

 ered; the peduncles very short; calix four-cornered, minute; 

 segments blunt, spreading; leaves pinnate, without an odd 

 leaflet. All parts of this plant, especially the bark, smell strong 

 of musk, and may be used instead of that perfume, for many 

 purposes. The wood is full of a bitter resinous substance, 

 which renders it unfit for rum hogsheads; being observed to 

 communicate both its smell and taste to all spirituous liquors: 

 but it is often cut for staves and heading, when there is a 

 scarcity of other timber. The powder of the bark is said to 

 be a good emetic; and is sometimes used among the negroes 

 for that purpose. Native of South America and the West 

 India islands, in woods, and by river-sides, where it flowers

in January and February. The English call it musk-wood and 

 alligator-wood; the French bois rouge. 



Guettarda; a genus of the class Monoscia, order Heptan- 

 dria. GENERIC CHARACTER. Calix: perianth one-leafed, 

 cyiindric, very short, quite entire, the outer edge more pro- 

 minent, deciduous. Corolla : one-petalled, funnel-shaped ; 

 tube cylindric, long; border six to nine cleft, with rounded 

 lobes shorter than the tube. Male Flowers. Stamina : fila- 

 menta four to six or seven in the throat of the corolla ; 

 antherse linear. Pistil : style filiform. Female Flowers, in 

 the same plant. Pistil: germen roundish, inferior;* style 

 filiform, longer than the stamina ; stigma subovate. Peri- 

 carp : drupe dry, roundish, depressed, torose, (according to 

 Jussieu with a sinous nut, six-celled, and containing six 

 seeds.) Seed: nut lobed, celled, perforated in the periphery 

 for cells; kernels solitary, four to six, roundish, bent at 

 right angles. ESSENTIAL CHARACTER. Calix: cylindric. 

 Corolla : six or seven cleft, funnel-shaped. Pistil : one. 

 Drupe: dry. The species are, 



1. Guettarda Speciosa. Leaves roundish, acute, heart- 

 shaped at the base, naked on both sides ; flowers seven or 

 nine cleft. A tall tree, with numerous, purplish, slightly 

 downy branches : the fruit is globose, depressed, its nut con- 

 taining six seeds. Native of Java, and cultivated in various 

 parts of the East Indies for the fragrance of its flowers. 



2. Guettarda Argentea. Leaves roundish, acute, heart-
