Phragmipedium caudatum

Class : Bedecktsamer (Magnoliopsida)
Order : Asparagales (Asparagales)
Family : Orchids (orchidaceae)
Subfamily : Cypripedioideae
Genre : Phragmipedium
Scientific name

The lady's slipper genus Phragmipedium ( fʀagmɪ'peːdɪʊm ) of the orchid family (Orchidaceae) consists of 23 species . They grow in Central and South America. It differs from the related genera Paphiopedilum and Cypripedium by the three-cell ovary, from the genus Selenipedium by the different plant structure and from the genus Mexipedium by the significantly larger growth.


The species of the genus Phragmipedium include perennial , herbaceous plants. The growth is sympodial , the individual shoot completes its growth with the inflorescence and sprouts from a basal renewal bud . The shoot is covered with leathery leaves in two rows . These are folded along the central rib and enclose the shoot with the leaf base. There is no separating tissue between the leaf base and the leaf blade.

The racemose or slightly branched inflorescence appears terminal. The inflorescence axis is covered with some bracts at intervals . The flowers open simultaneously or one after the other. The two lateral sepals are fused together, otherwise the petals are free. The petals are greatly elongated in some species, so they can reach 75 cm in length in Phragmipedium caudatum . The lip is shaped like a bag, the edges curved inwards. The column bears two fertile, rounded stamens and a sterile one, which is shaped into a shield-shaped staminodium . The three scars have grown together to form a surface.

Systematics and botanical history

The first described species of this genus was described by John Lindley as Uropedium lindenii in 1846 . Since the justification of the new genus referred to a 'monstrous' species without a shoe-shaped lip, the generic name Phragmipedium , established by Robert Allen Rolfe in 1896 , was later recognized and established as a "nomen conservandum". The orthographic variant Phragmopedilum used by Rolfe in 1901 is a synonym .

The genus occurs from southern Mexico through Central America, Colombia , Venezuela to Brazil and Bolivia and includes, depending on the assessment, about twenty valid species:
