$The style is the prolongation upwards of the infolded lamina of the Carpellary leaf. It consists of a cellular sheath having enclosed within it fibro-vascular bundles, which are arranged in a circle on its inner surface. The cavity of the style is filled up by a loose, soft and humid cellular tissue. This is called the conducting tissue. It pla5's a very important part in the process of fecundation. The style arises from the organic apex of the ovar}-, and its place as regards geometrical apex of the ovary is determined by the position of the organic. It may either be apicular, lateral, or basilar,—in the latter case it acquires the name of the gynobase. In a compound ovarium the number of the styles corresponds to that of the Carpella. The stigma is formed by the expansion of the lax cellular tissue at the point where the canal of the style opens externally. Its outer cells acquire the shape of diminutive papilloe, hairs, and so forth. In compound ovaria, its position is alternate with that of the dissepi- ments. An a])parent anomaly to this rule is found in the poppy tribe— here the divisions of the stigma are opposite to the dissepiments— this appearance is occasioned by the divisions being formed by the adhe- sion of two half-stigmata,—in this tiibe of plants—the stigmata being each of them bifid. (9.) The seed is the ripe ovulura. It consists of two coats and the embryo: the outer coat or testa is formed by the blending of the primine and the secundine, and the inner by the sac of the amnios and the nucleus. When the albumen exists, it forms one of the constituent parts of the seed. Its position is next to the embryo. The names of the chief varieties of the seed are the ortho-tropous, camphylotropous, camptotropous, anatropous, and amphitropous. (10.) In the following table are given the chief characters of the 4 sub- classes into which De—Candolle divided the Dicolytedones. 1. Thalamiflora;, \ Stamens hypogynous. i rruit apocarpous. 2. Calyciflorse, Stamens perigynous and epigynous. 3. CoroUiflora;, Stamens inserted upon the corolla. 4. Monochlamydece,.... No corolla, only calyx. II. Characters: flowers rosaceous or papilionaceous. Stamens diadel- phous and 10 or more, perigynous or hypogynous, fruit a legume. Leaves alternate or opposite, and stipulate. 1. Division—Papilionaceoe—characters. Papilionaceous flowers, sta- mens perigynous. 2. Division Coesalpineoe—flowers rosaceous, stamens perigynous. 3. Division Mimosce—stamens hypogynous. The Acacias such as the Acacia Arabica and the Catharto-carpus Fistula are, as far as I recollect just, now, some of the important medicinal plants belonging to this class. From the Acacia Arabica, gum Arabic is obtained and from the Catharto-carpus fistula a valuable purgative. Sandal-wood is also derived from a plant of this order whose botanical name I dont at present remember—it is, however, of no medicinal use. Chunder Coomar Dev. PRACTICE OF PHYSIC.
