Physoceras is a genus of flowering plants from the orchid family, Orchidaceae. It is native to Madagascar and Réunion; it was also formerly present in Mauritius but now apparently extinct there. [1] [2]
A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
The flowering plants, also known as angiosperms, Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 64 orders, 416 families, approximately 13,164 known genera and c. 369,000 known species. Like gymnosperms, angiosperms are seed-producing plants. However, they are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure; in other words, a fruiting plant. The term comes from the Greek words angeion and sperma ("seed").
The Orchidaceae are a diverse and widespread family of flowering plants, with blooms that are often colourful and fragrant, commonly known as the orchid family.
Angraecopsis is a genus of plants in family Orchidaceae. It was first described by Fritz Kraenzlin in 1900 and given its name on account with the genus' similarity to Angraecum species. Angraecopsis are native to Africa, Madagascar, Réunion, Mauritius and the Comoros. The growth habit is rather small and the leaves emerge from a woody stem.
