Piperia is a genus of the orchid family Orchidaceae.

DistributionEdit

The genus is composed of eight species distributed from Russia through North America.

DescriptionEdit

This genus has the following characteristics:

  • a bisexual perennial nongreen plant that grows from buried tubers
  • fruit capsule bearing numerous minute seeds
  • pollen that is sticky, and which is removed as sessile anther sacs
  • stigma fused with its style into a column.

The genus members manifest generally cylindrical spikes or racemes.

The subsurface architecture of these terrestrial wild orchids consists of a rhizome structure, from which emanate tubers. The rhizome extracts nutrients from fungal intermediates and may also store some of these nutrients. A basal rosette of leaves develops from the tuber at the surface of the soil, each of the two or three leaves being lanceolate in shape. Each leaf ranges from 10 to 15 centimeters in length and 20 to 35 millimeters in width. Leaves of younger plants are often more diminutive in size.

CultureEdit

NamingEdit

This genus was named after American agronomist Charles Vancouver Piper.
