an inflorescence in which numerous peduncles are given off in all directions from the summit of a branch, and these bear a terminal flower and secondary pedicels from below it, as in the common elder.
applied to trees or shrubs the leaves of which are shed annually, so that the branches become bare; the opposite of evergreen; applied also to other organs which fall off after their functions have been performed.
Decomposite, subdivided to a considerable extent. Decumbent, reclining upon the surface of the earth, but with a tendency to rise again towards the extremity.
prolonged below the point of insertion, as if running downwards, as in the leaves of most thistles.
bursting by a regular line of suture.
furnished with small teeth.
having the stamens united into two distinct sets or bundles.
forked or subdivided once or repeatedly, with the branches in pairs.
plants whose seeds have two or more cotyledons or seed-lobes.
possessing two cotyledons.
having four stamens, of which two are longer than the other two.
spreading widely in an irregular horizontal manner.
applied to simple leaves, where the lobes are very narrow and cut nearly to the base of the limb; and to compound leaves, where the leaflets are all placed at the very extremity of the petioles. Dioecious, bearing unisexual flowers of the same species on distinct individual plants. Discoid, disk-like, round, and somewhat thickened, with the margins also rounded. Disk, a fleshy expansion between the stamens and pistil, occurring in some flowers, and considered to result from the abortion of an inner whorl of stamens; also the central portion occupied by the flowers in a capitule. Dissected, having the segments very numerous and deeply cut, as in some leaves. Dissepiment, the vertical partitions in the interior of an ovary, dividing it wholly or partially into two or more cells. Distichous, longitudinally arranged in two rows, on opposite sides of a common axis. Distinct, wholly unconnected with adjoining parts or organs. Divaricate, branching off and spreading irregularly at an obtuse angle. Dorsal, attached to the back of any organ. Downy, covered with short weak close hairs. Drupaceous, possessing the character of a drupe. Drupe, an indehiscent, superior, one-celled fruit, fleshy externally and bony within, containing one or two seeds, as the plum, peach, etc. Elliptical, approaching the form of an ellipse, that is an oval rounded at the ends, or an oblong widened in its smaller diameter. Emarginate, slightly notched at the summit. Embryo, the rudiment of a plant contained in the seed.
