ORDER LXIV.—MYRTACEA, Juss. 
Calyx 4—5—6—8-cleft, the limb sometimes cohering in two portions, 
sometimes in one and then falling off like a cap or lid. Petals peri- 
gynous, as many as the segments of the calyx and alternating with 
them, sometimes slightly united at the very base; rarely wanting: 
wstivation imbricated. Stamens inserted with the petals, rarely as 
few, sometimes twice as many, usually indefinite: filaments either all 
distinct, or monadelphous, or variously polyadelphous, in sestivation 
curved inwards : anthers ovate, bilocular, small, bursting longitudinally. 
Ovarium cohering with the tube of the calyx, formed of two or more 
carpels, the dissepiments rarely imperfect, and hence 1- to 15-celled : 
style and stigma simple. Placente in the axis. Fruit dry or fleshy, 
dehiscent, or indehiscent, 2-6- or many-celled, or by the obliteration of 
the dissepiments 1-celled. Seeds rarely solitary or. few, usually inde- 
finite. Albumen 0. Embryo straight or curved: radicle next the hi- 
lum : cotyledons distinct, or sometimes consolidated into one mass with 
the radicle.— Trees or shrubs. Leaves usually opposite, entire, and 
with transparent dots, sometimes alternate, rarely serrated, and rarely 
without dots. 
I. MELALEUCA. Linn. s Lam. ill. t. 641 ; Gertn. fr. 1. t. 35. 
Calyx-tube nearly hemispherical; limb 5-partite. Petals 5. Stamens nu- 
merous, combined into 5 elongated bundles, that alternate with the petals. 
Anthers incumbent. Style filiform. Stigma obtuse. Capsule connate with 
and inclosed in the thickened tube of the calyx, which is sessile on and ad- 
nate at its base to the flower-bearing branch, 3-celled, many-seeded. Seeds 
angular.—Trees or shrubs. Leaves alternate or opposite, quite entire, equal 
at the base. Flowers perfectly sessile or somewhat combined with the 
branch, arranged in spikes or heads, whitish or yellowish or purplish. 
* 1007. (1) M. eajuputi (Roxb.:) arborescent : branchlets pendulous: leaves 
alternate, elliptic or narrow-lanceolate, more or less acute, slightly faleate, 9- 
nerved: flowers a little distant, forming spikes : rachis, calyx, and young 
branches, densely pubescent or almost villous.—Roab. hort. Bengh. p. 593 f. 
Ind. 3, p. 394; Wight! cat. n, 1065.—M. minor, Sm. in Rees’ cyel. (but not 
Arbor alba minor of Rumphius); DC. prod. 3. p. 212; Wall. L. n. 3645.— 
M. Leucadendron, Lam. ill. t. 641. f. 4 (not Linn.).—Arbor alba Javaniea, 
Rumph. Amb, 2. p. 74. 5 i 
This alone yields the cajeput oil, from which circumstance, as well as from 
its not being the Arbor alba minor described and figured by Rumphius (al- 
though that synonym be quoted by Smith and De Candolle), we have adopt- 
ed the name given by Roxburgh. M. minor appears to be a shrub, wi 3- 
nerved leaves, and perhaps not known to any botanist of the present day h 
Hamilton (in Wern. soc. tr. 6. p- 301) refers to it Rumph. Amb. 2. t. 17. f. 1. wit
