Section (botany)

In botany, a section is a taxonomic rank below the genus, but above the species. The subgenus, if present, is higher than the section, and the rank of series, if present, is below the section. Sections are typically used to help organise very large genera, which may have hundreds of species...

 Amandae. Split from Masdevallia as recently as 2006, this genus is not yet fully accepted in all botanical forums.

Description

Characteristics that distinguish this genus from Masdevallia are:

• in large or small plants the ramicauls are shorter than the coriaceous leaves
• an erect raceme with keeled or crested ovaries usually possessing inflated floral bracts
• species exhibit a series of simultaneously blooming flowers borne by a peduncle with a round cross-section
• sepals are usually long-tailed and variously connected into a shallow cup or arching cylindrical tube
• petals are callous on the lower half and are often denticulate along the margins
• the lip is usually divided by marginal folds
