![]() The fruit is a capsule (splits along two or more seams, apical teeth or pores when dry, to release two or more seeds) The fruit is dry and splits open when ripe the fruit is at least somewhat flattened.The capsule splits by two main valves, teeth or pores The upper lip of the bilabiate corolla has two lobes The stamens are attached to one another at or near their bases The stamens within a cycle differ in length or width the stamens are attached at or near the bases of the petals or tepals.The sepals are fused to each other (not other flower parts), at least near their bases The sepal outline is linear (extremely narrow, thread-like) The sepal lobes are shorter than the fused portion The sepals are pressed against the corolla, or jutting stiffly upward there are two or more auricles per sepal.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 surfaceĪll the flowers have both carpels and stamens (synoecious) The petals of the flower do not have folds or plaits The petal narrows gradually or does not narrow at the base 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 below the point of petal and/or sepal attachment There are five petals, sepals, or tepals in the flower 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 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) The flower has both pollen- and seed-producing parts The flower has an inferior ovary, with or without a hypanthium 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 calyx grows to cover or partially cover the fruit The anthers show no hint of a pink, reddish or purplish tint The anther is attached by its base to the filament
