CalyptrionCalyptrion 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.
AgateaAgatea is a genus of flowering plants in the violet family Violaceae, with seven accepted species, found in New Guinea and New Caledonia. Lianas or reclining shrubs with lanceolate to ovate leaves. The flowers are in terminal pseudo-racemes or racemoids, with white corollas that are strongly zygomorphic (bilaterally symmetrical) with the very large bottom petal differentiated into a claw and blade and saccate (pouch like) at the base.
AnchieteaAnchietea is a genus of flowering plants in the violet family Violaceae, with six accepted species, found in tropical South America. Lianas or reclining shrubs with oblong-lanceolate to ovate leaves. The flowers, which may be unisexual or bisexual, are in axillary racemoids or fascicles, with a white to orange corollas that are strongly zygomorphic (bilaterally symmetrical) with the long bottom petal weakly differentiated with a well exserted (projecting) spur.
ViolaceaeViolaceae is a family of flowering plants established in 1802, consisting of about 1000 species in about 25 genera. It takes its name from the genus Viola, the violets and pansies. Older classifications such as the Cronquist system placed the Violaceae in an order named after it, the Violales or the Parietales. However, molecular phylogeny studies place the family in the Malpighiales as reflected in the Angiosperm Phylogeny Group (APG) classification, with 41 other families, where it is situated in the parietal clade of 11 families.
