'''Ponthieva''' (commonly called Shadow Witch) is a genus form the orchid family ([[Orchidaceae]]). They are named after Henri de Ponthieu, a French merchant who sent West Indian plant collections to Sir [[Joseph Banks]] in 1778.
This genus occurs from the southern states of the USA to Mexico, the Caribbean and tropical America. They are mainly terrestrial plants with [[sympodial]] growth, but some are [[epiphyte]]s.
Their fibrous root show long and soft hairs. Some of the branches are thickened. The simple [[Plant stem|stem]] grows from [[rhizome]]s and carries thin, basal [[Leaf|leaves]] with a slight to a somewhat longer stalk. The few to many, erect [[flower]]s grow on bracteate peduncles in a terminal [[raceme]]. Their dorsal [[sepal]] is slightly joined to the [[petal]]s at the apex. The petals are free or sometimes fused to lower flanks of the [[column]]. The lateral sepals are distinct or joined.
The clawed [[labellum|lip]] is fused to the base of the short [[column (botany)|column]]. This is semiterete, i.e in the form of a cylinder, rounded on one side and flat on the other. It is slightly winged towards the pointed apex.
There are four, yellow, club-shaped [[pollinium|pollinia]] that are joined in pairs.
