![]() The petiole attaches at the basal margin of the leaf blade the leaves have no leaf stalks, but attach directly to the stem.The upper side of the leaf is dull or slightly shiny The hairs are standing up straight or curved in different directions The leaves are green, with an expanded blade and a leaf-like texture The leaves drop off in winter (or they whither but persist on the plant) The leaf blade has one main vein running from the base towards the tip (it may or may not have secondary veins) The major veins of the leaf blade branch, but do not rejoin The leaf blade is herbaceous (has a leafy texture) The upper side of the leaf blade is relatively uniform in color the leaf blade is ovate (widest below the middle and broadly tapering at both ends).the leaf blade is lanceolate (lance-shaped widest below the middle and tapering at both ends).The secondary veins branch off at intervals from the primary vein The leaf blade has simple hairs with no glands, and not tangled or wooly The underside of the leaf has no noticeable bloom the base of the leaf blade is cuneate (wedge-shaped, tapers to the base with relatively straight, converging edges), or narrow.the leaf has a distinct leaf stalk (petiole).Opposite: there are two leaves per node along the stem The leaf blade does not have inflated hairs on it The upper side of the leaf is not hairy, or it has very few hairs the underside of the leaf is not hairy, or it has very few hairs.the underside of the leaf is fuzzy or hairy.The flower has one or more bracts associated with it The plant has bracteoles between the primary bracts and the flowersįinal leaf segment length (compound lvs only)įinal leaf segment length to width ratio (compound lvs only)įinal leaf segment width (compound lvs only) The fruits do not have thorn-like defensive structures The plant has axile placentation, in which the ovules are attached where the septa of a compound ovary are united, usually on the central axis, or to the septa themselves The fruit is a schizocarp (when dry it splits into sections, each holding one or more seeds) The fruit is dry but does not split open when ripe the upper lip of the bilabiate corolla has two lobes.the upper lip of the bilabiate corolla has one lobe.The stamens are not attached to one another the stamens within each cycle are the same.the stamens within a cycle differ in length or width.The stamens are not attached to the petals or tepals The sepals are fused to each other (not other flower parts), at least near their bases the sepal outline is roughly triangular.the sepal outline is lanceolate (lance-shaped narrow, gradually tapering from the base to the tip).The sepal lobes are approximately the same length as the fused portion The sepals do not have appendages on them The sepals are green or brown, and leaf-like in texture There are no hairs on the inner/upper petal surface 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 perianth is funnelform (funnel-shaped) The ovary is above the point of petal and/or sepal attachment there are four petals, sepals, or tepals in the flower.there are five petals, sepals, or tepals in the flower.there are no noticeable marks on the petals.the petals have spots or streaks on them.The flowers are arrayed in a spiral around the inflorescence axis or branches, or occur singly, or in several ranks The petals or the sepals are fused into a cup or tube The style is lobed at the tip, and unbranched there is only one way to evenly divide the flower (the flower is bilaterally symmetrical).there are two or more ways to evenly divide the flower (the flower is radially symmetrical).the flower has either only pollen- or only seed-producing parts.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 ![]() 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 ![]()
