Genus of plants
Piriqueta is a genus of flowering plants belonging to Turneroideae (Passifloraceae).
Description.
"Piriqueta" is a genus of herbs or subshrub dicots.
Morphology.
Most members of "Piriqueta" are perennial or suffrutic herbs, there are some shrubs and some annual species.
All members of "Piriqueta" have the same floral organization: short calyx tubes that are attached to petal claws, coronas, and filaments. The peduncle and pedicels are free. Seeds are reticulate in all species, two thirds of the species have puberulent seeds, others have glabrous seeds. They are generally hairy, though some only have hair in the floral regions.
Over half of "Piriqueta" species have setiform glandular hairs and tuberculate fruits, some with axillary inflorescences.
Various members of "Piriqueta", see list below, have a unique reproductive system called distyly, in which, two floral morphs are present which differ in their placement of anthers and style length. More rarely, some species show tristyly in which three floral morphs are present.
Karyotype.
30% of "Piriqueta" are polyploids. The basic chromosome number is x=7.
Taxonomy.
"Piriqueta" was originally described in 1775 by J. F. B. Fusée Aublet in "Histoire des plantes de la Guiane Françoise", 1877. In this book, he describes "Piriqueta villosa". Aublet describes "P. villosa" as being deciduous, with ovate hairy leaflets, having five "scaly" petals with cup alternation, five filaments, ovate and bilocular anthers, five six-branched pistils with flat fleshy wide stigmas, and being covered in red stiff hairs.
In 1777, Giovanni Antonio Scopoli would publish the genus under "Burghartia" and would place the genus in the tribe Sauvagesieae of Ochnaceae.
In 1789, Johann Christian Daniel von Schreber would publish the genus under "Burcardia". The description is similar to that of Aublet's with the exception of the petals described as "heart" shaped.
Scopoli's and Schreber's descriptions both refer to "Piriqueta" as a synonym, neither provided type species in their descriptions.
Distribution and habitat.
Members of "Piriqueta" have native ranges throughout tropical and subtropical regions of North, Central, and South America.
Various members of "Piriqueta" have been introduced to Java, Malaysia, and Thailand.
