the twigs are branched into several green stalks, two inches 

 long, which just at the bottom are branched into others 

 sustaining several whitish-green flowers with purple-headed 

 stamina. Native of Jamaica, found in abundance between 



Passage Fort and St. Jago de la Vega. The trees and 



shrubs of this genus, being natives of hot countries, cannot be 

 preserved in England, except in a stove. They may be pro- 

 pagated by seeds sown in pots, and plunged into a hot-bed: 

 when the plants are fit to remove, plant each in a separate 

 small pot, and shade them until they have taken new root. 

 They may also be increased by cuttings during any of the 

 summer months. Plant them in a dry gravelly soil. 



2. Trichilia Spondioides. Leaves unequally pinnate, sub- 

 hirsute ; pinnas numerous, the lower ones larger; racemes 

 axillary. Stem ten feet high or more, upright, divided into 

 very few branches ; leaves a foot long ; flowers inodorous, 

 small, about thirty in a raceme; calix half five-cleft, spread- 

 ing, flat, very small; petals whitish, spreading; fruit round, 

 first green, then purplish, when ripe as large as a great garden 

 pea, breaking into three membranes, expanding themselves, 

 each having a crest or rising in the middle, and shewing 

 three almost triangular distinct kernels, covered over with a 

 thin scarlet pulp. Native of Jamaica, St. Domingo, and 

 Carthagena; flowering there principally in November. 



3. Trichilia Einetica. Leaves pinnate, villose underneath; 

 leaflets elliptic ; branches villose, round ; flowers corymb- 

 panicled, greenish-yellow, twice as large as in the preceding 

 species. Forskall describes this as a large tree, with alter- 

 nate downy branches : the Arabs call it Roka. The flowers 

 resemble orange-blossoms ; and the fruit, mixed with per- 

 fumes, is used by the women for washing their hair. The 

 ripe seeds are made into an ointment with oil of Sesamum, 

 as a remedy for the itch. Native of Arabia Felix, where it 

 is found upon the mountains. 



4. Trichilia Glabra. Leaves pinnate, smooth ; outmost 

 leaflets larger ; racemes axillary, very short ; capsules globu- 

 lar, green. It is a tall branching tree, with an unpleasant 

 fetid smell. Native of the Havannah, in mountain woods. 



5. Trichilia Pallida. Leaves unequally pinnate, membra- 

 naceous ; racemes axillary and terminating ; flowers eight- 

 stamined ; capsules two-valved. This is a tree of about 

 twelve or fifteen feet high, smooth, and branchy; branches 

 horizontal; petals pale or whitish. Native of the West In- 

 dies, flowering in February or March. 



6. Trichilia Moschata. Leaves alternately pinnate; ra- 

 cemes axillary ; flowers subdecandrous, one-petalled ; cap- 

 sules one-seeded. This is a tree twenty feet high; branches 

 subdivided, with a smooth striated bark. Native of Jamaica, 

 where it is called Muskwood, on account of the smell of the 

 plant when rubbed. 



7. Trichilia Spectabilis. Leaves pinnate; leaflets obovate; 

 racemes axillary, compound. Native of New Zealand. 



8. Trichilia Alliacea. Leaves pinnate: leaflets lanceolate, 

 acute; racemes axillary, superdecompound. Native of the 

 island of Namoka. 



9. Trichilia Heterophylln. Leaves pinnate or ternate; leaf- 

 lets ovate, acuminate ; racemes axillary; flowers eight-sta- 

 mined ; stigma club-shaped. This is between a shrub and a 

 tree, or may be called either ; bark gray, variegated by fis- 

 sures. Native of Madagascar. 



10. Trichilia Trifoliata. Leaves ternate ; leaflets obovate, 

 shining. A tree fifteen feet high, exhaling from every part 

 a disagreeable, through not powerful odour; branches numer- 

 ous, round, irregular, spreading, often from the very ground; 

 flowers small; calix bell-shaped, erect; petals whitish, erect, 

 three times as long as the calix. In Cura9ao it is called 



Kerse-boom, or Cherry-tree, although it has nothing in com- 

 mon with that. The negresses use a decoction of the roots 

 to procure abortion. Native of Curagao in dry pastures, 

 flowering in April and May. 



11. Trichilia Nervosa. Leaves ternate; leaflets ovate, 

 acute, their ribs hairy beneath. Branches villose, tomentose 

 at the end ; flowers in short panicles, clustered, with a lan- 

 ceolate leaflet at the base of each; corolla villose, twice as 

 long as the calix. Native of Java. 



12. Trichilia Spinosa. Leaves simple, ovate, emarginate; 

 branches thorny. Native of the East Indies. 



Tricftocarpus ; a genus of the class Polyandria, order 

 Digyniii. GENERIC CHARACTER. Calix : perianth one- 

 leafed, four or five parted ; segments ovate, acute, spreading, 

 permanent. Corolla: none. Stamina: filamenta very many, 

 sixty to seventy, capillary, longer than the calix, inserted 

 into the receptacle; antherse small, roundish. Pistil: ger- 

 men ovate, villose ; styles two, longer than the stamens, 

 bifid at the top; stigmas obtuse. Pericarp: capsule ovate, 

 four-cornered, one-celled, four-valved, bristly; bristles long, 

 rigid, deciduous. Seeds: numerous, small, fastened to a free 

 ovate-oblong receptacle involved in a viscid membrane. ES- 

 SENTIAL CHARACTER. Calix : four or five parted. Corolla : 

 none. Styles: two, bifid. Capsule: bristly, one-celled, four-

1. Trichocarpus Laurifolia. Leaves scattered, coriaceous, 

 oblong, acute, quite entire, veined, smooth, petioled; corymbs 

 few-flowered, subdichotomous, lateral. This tree is about 

 fifty feet in height, and grows on the banks of rivers in Gui- 

 ana, flowering and fruiting in November. 



Trichomanes ; a genus of the class Cryptogamia, order 

 Filices. GENERIC CHARACTER. Fructifications: inserted 

 into the margin of the frond, separate. Involucre: one-leaf- 

 ed, urn-shaped, undivided, opening outwards. Columns: ex- 

 tending beyond the involucre like styles. Observe. Habit
