 and shorter than it, flattened, bearded in the middle, 3 sterile, 

 2 fertile ; anthers adnate, oblong, heart-shaped. Ovaries 5,

 the sterile stamens. Styles 5, rising from the tops of the 

 ovaries, connected in one, terminated by a single, 5-lobed, capi- 

 tate stigma. Fruit of 5 (but sometimes fewer from abortion) 

 1 -seeded carpels. A villous herb, with opposite or alternate, 

 stalked, ternate leaves, full of fine pellucid dots. Peduncles

Cult. The seeds of this plant 

 should be sown in a pot of light 

 earth, placing it in a hot-bed, and 

 when the plants are of sufficient 

 size they should be planted into 

 separate pots, and shaded until 

 they have taken fresh root ; after 

 this they may. be placed in the stove, where they will ripen their 

 seed. 



Tribe VII. 



ZANTHO'XYLE^E (plants agreeing with Zanthoxylum 

 in important characters). Andr. Juss. in mem. mus. 12. p. 497. 

 Flowers of separate sexes, regular. Calyx divided into 3, but 

 usually 4-5. Petals equal in number, frequently longer, usually 

 twisted in the bud, rarely wanting. Male flowers, with the 

 stamens equal in number to the petals, rarely double that 

 number, for the most part longer than them, inserted round 

 the base of the gynophore. Female flowers with abortive 

 stamens and a short style. Ovaries seated on the receptacle, 

 equal in number to the petals or fewer, sometimes distinct 

 or partly so, with 2 ovulae in each. Styles equal in number 

 to the ovaries, simple, sometimes free, sometimes joined, some- 

 times wanting. Stigma 2-5-lobed, or in the free styles simple. 

 Fruit simple, baccate, or membranous, 2-5-celled, sometimes 

 multiple. Seeds solitary or twin, pendulous, smooth, and shining. 

 Albumen fleshy, with a superior radicle, and ovate, flat coty- 

 ledons. Trees or shrubs, with alternate or opposite, simple, but 

 more frequently abruptly or impari-pinnate, dotted or dotless 

 leaves. Flowers axillary and terminal, variously disposed, male 

 and female intermixed, sometimes on different branches, some- 

 times on different trees ; pedicels bracteolate. Divers parts 

 bitter and aromatic. 



XXXVIII. DICTYOLO'MA (from SIKTVOV, dictyon, a net, 

 and \to/ja, loma, a fringe ; in allusion to the seeds being expanded 

 on the back into a netted wing). Andr. Juss. in mem. mus. 12. 

 p. 499. t. 24. no. 36. 



LIN. SYST. Monoecia, Penttindria. Flowers of separate 

 sexes. Calyx deeply 5-parted. Petals 5, longer. Male flowers, 

 stamens 5, opposite the petals, about equal ; filaments each rising 

 from the back of a dense woolly scale, bearing 5 abortive, 

 slender ovaries, shorter than the stamens. Female flowers bear- 



ing 5 productions like stamens, each terminated by a barren 

 anther. Ovaries 5, joined in one, seated on a short gynophore, 

 downy. Styles 5, connected into one, short, thick, terminated 

 by a single 5-lobed stigma. Fruit of 5 distinct carpels, opening 

 inwardly, 2-valved, 3-4-seeded. Seeds kidney-shaped, expanded 

 on the back into an elegant netted wing. Embryo arched. A 

 little tree, with alternate, pinnate leaves ; leaflets nearly oppo- 

 site or alternate, unequal-sided, with glandular margins, without 

 dots. Terminal branches bearing the flowers, dividing into a 

 broad corymb ; pedicels bracteate. Flowers downy-white, male 

 and female intermixed.

LIN. SYST. Dioecia, Octdndria. Flowers of separate sexes. 

 Calyx 4-parted. Petals 4, longer. Male flowers. Stamens 8, 

 the 4 opposite the petals shortest ; filaments awl-shaped, smooth, 

 inserted round the base of the oblong gynophore. Ovaries 3-4, 

 distinct, seated on the fleshy tetragonal receptacle. Styles 3-4, 

 distinct at the base, but connected at the apex, terminated by a 

 4-lobed stigma. Drupes 4, or fewer from abortion, 1-seeded. 

 Seeds egg-shaped. Embryo straight. A tree with simple 

 leaves, opposite, or 3 in a whorl, serrated, quite smooth, full of 

 pellucid dots, with an aromatic smell. Peduncles axillary, tri- 

 chotomously panicled, with 2 opposite bracteas at the divisions ; 

 pedicels bracteolate. Female flowers on distinct branches, and 

 perhaps on distinct trees. Petals convolute in the bud.

LIN. SYST. Dioe'cia, Tetrandria. Flowers of separate sexes. 

 Calyx 4-parted. Petals 4, hardly equal the length of the calyx. 

 Male flowers. Stamens 4, short, inserted round about a gland- 

 like, central, 4-lobed body. Female flowers ; stamens 4, sterile. 

 Ovaries 4, seated on a 4-lobed receptacle, each terminated by a 

 simple, acute, reflexed stigma. Drupes 4, 1-seeded. Shrubs, with 

 impari-pinnate leaves, with 6 pairs of opposite, entire, or serrated 

 leaflets, without dots. Flowers small, purplish inside, disposed 

 in interrupted glomerate spikes or racemes. Branches, peduncles, 

 petioles, and nerves of leaves clothed with simple rufescent down. 

 A fifth part is generally added to the flowers. Divers parts of 

 the shrubs very bitter. 



1 B. ANTIDYSENTE'RICA (Mill. fasc. t. 25.) leaflets quite entire, 

 clothed with rusty villi on the nerves beneath ; racemes simple, 

 spike-like. Jj . S. Native of Abyssinia. Woogi-noos, Bruce's

 Drupe sometimes solitary, or perhaps connected together. Guers. 

 in bull, philom. 3. no. 84. p. 182. This species is known in 

 Abyssinia by the name of Woodginoos. The root is a specific 

 in dysentery. It is a plain simple bitter, without any aromatic 

 or resinous taste, leaving in the throat and palate something of 

 roughness, resembling Ipecacuanha. The bark of this tree is 

 sold under the name of Angostura bark. See Galipea Cuspdria.
