=cuspidate=, tipped with a sharp point. =cyme=, an inflorescence in which the flowers are produced centrifugally on successive lateral axes. =deciduous=, applied to plants whose leaves are all shed at a certain season of the year. =decompound=, several times subdivided or compound, applied to leaves or inflorescence. =decumbent=, spreading horizontally, then turning upwards. =decurrent=, applied to leaves, the margins of which run down the stem below the insertion of the petiole. =decussate=, when leaves are in pairs successively at right angles to each other on the stem. =dehiscent=, splitting (of fruits to let out the seeds). =dentate=, dog-toothed, _i.e._, with teeth of equal sides. =denticulate=, finely dog-toothed. =diadelphous=, of stamens when they are joined by their filaments into two groups, _e.g._, some of the =Papilionaceæ=. =diandrous=, with 2 stamens. =dichotomous=, applied to a stem, branch or inflorescence which forks again and again. =dicotyledons=, with two seed-leaves. =didymous=, divided into two lobes, in pairs. =didynamous=, with two long and two short stamens. =diffuse=, widely and loosely spreading. =digitate=, applied to a compound leaf, the leaflets of which spread like the fingers of a hand. =diœcious=, of plants the stamens of which are in flowers on one individual and the ovary and style on another. =disc= or =disk=, the receptacle on which are set flowers in a capitulum, as in =Compositæ=, or at the base of the ovary within the flower. =disc-florets=, the regular tubular florets of certain =Compositæ=, which, if accompanied by ligulate florets, occupy the centre of the disc, while the latter are on the rim and called ray-florets. =distichous=, arranged in the same plane, _i.e._, at two right angles to each other. =divaricate=, widely spreading. =drupe=, a fleshy indehiscent fruit containing a “stone” in which the seed is enclosed. =echinate=, covered with prickles, like a hedgehog. =elliptical=, shaped like an ellipse, oval. =emarginate=, notched, usually at the apex of a leaf or petal. =ensiform=, sword-shaped. =entire=, applied to the margin of a leaf which is not toothed or notched. =epicalyx=, applied to a row of bracts, sometimes joined together, outside the calyx, _e.g._, some of the =Malvaceæ=. =epigynous=, apparently seated upon the ovary. =epipetalous=, applied to stamens seated on the petals. =epiphyte=, a plant which grows on another without being parasitic, _e.g._, some =Orchids=. =evergreen=, applied chiefly to shrubs and trees which bear leaves all the year round. =exserted=, protruding, applied chiefly to stamens which show outside the flower. =exstipulate=, having no stipules. =extra-axillary=, from outside the axil. =falcate=, scythe- or sickle-shaped. =fascicled= or =fasciculate=, in bundles or tufts. =fastigiate=, with parallel erect clustered branches. =fertile=, capable of bearing fruit, applied also to stamens bearing pollen.
