Plant taxonomy
Plant taxonomy is the science that finds, identifies, describes, classifies, and names plants. It is one of the main branches of taxonomy (the science that finds, describes, classifies, and names living things). Plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two. In practice, "plant systematics" involves relationships between plants and their evolution, especially at the higher levels, whereas "plant taxonomy" deals with the actual handling of plant specimens.
Calyptrion
Calyptrion is a genus of flowering plants in the violet family Violaceae, with four known species. Lianas with oblong-lanceolate to ovate leaves. The flowers are situated in axillary or terminal racemes, rarely solitary, with white corollas, and are strongly zygomorphic (bilaterally symmetrical), the bottom petal being slightly longer than the others and more weakly differentiated, and with a very long spur. The stamens have free filaments, with the lowest two being calcarate (spurred) and possessing a large dorsal connective appendage that is entire and oblong-ovate.
