the upper side of the leaf is not hairy, or it has very few hairs.the upper side of the leaf is fuzzy or hairy.The underside of the leaf is not hairy, or it has very few hairs The flower has one or more bracts associated with it The fruits do not have thorn-like defensive structuresįinal leaf segment length (compound lvs only)įinal leaf segment length to width ratio (compound lvs only)įinal leaf segment width (compound lvs only) the plant has basal placentation, where one or a few ovules develop at the base of a simple or compound ovary.The fruit is an achene (dry, usually one-seeded, does not separate or split open at maturity) The fruit is an achene (dry, indehiscent, and usually one-seeded) the achenes are another shape in outline.The achenes are perpendicular to the plane of the perianth (vertical) The stigmas are positioned on the inner surface of the style The stamens are not attached to one another The stamens are not attached to the petals or tepals the sepal outline is ovate (widest below the middle and broadly tapering at both ends).the sepal outline is eliiptic (widest near the middle and tapering at both ends).the sepals are slightly curved outwards from the corolla.the sepals are curved outwards and downwards from the corolla.The sepals do not have appendages on them The sepals are green or brown, and leaf-like in texture The petal outline is obovate (roughly egg-shaped, but with the widest point above the middle of the leaf blade)Īll the flowers have both carpels and stamens (synoecious) The petals of the flower do not have folds or plaits The petals are thin and delicate, and pigmented (colored other than green or brown) The flower includes two cycles of petal- or sepal-like structures The ovary is above the point of petal and/or sepal attachment There are no noticeable marks on the petals The flowers are arrayed in a spiral around the inflorescence axis or branches, or occur singly, or in several ranks The axis of the inflorescence has hairs entirely without glands The flower has both pollen- and seed-producing parts The flower has a superior ovary, and lacks a hypanthium The filament is smooth, with no hairs or scales There are no cleistogamous flowers on the plan The carpel is solitary or (if 2 or more) the carpels are not fused to one another There are two or more ways to evenly divide the calyx (the calyx is radially symmetrical) The anthers have narrow slits or furrows that run lengthwise along the anthers The anthers show no hint of a pink, reddish or purplish tint The fruit is dry but does not split open when ripe There are five petals, sepals, or tepals in the flowerīoth the petals and sepals are separate and not fused There are two or more ways to evenly divide the flower (the flower is radially symmetrical) The edge of the leaf blade has lobes, or it has both teeth and lobes basal: the leaves are growing only at the base of the plant.alternate: there is one leaf per node along the stem.the leaves are simple (i.e., lobed or unlobed but not separated into leaflets).the leaves are compound (made up of two or more discrete leaflets.
