Varieties :
This species varies in size as well as in intensity of the flower colour, but the differences with the normal-type are so small that there is actually no bases for naming varieties and forms.

The following 2 varieties have been named in the literature:
   var. delicata
   var. maxima

Etymology : Phrag. lindenii is named after Jean Jules Linden (1817-1898), the prominent Luxemburg-Belgian orchid collector and grower. Publisher of the famous 17 part Lindenia and L'Illustration Horticole volumes 17-43.

Description
Plant :
Leaves :
Inflorescence :
Flower : The lip of this species has the same shape as the petals. Because of the missing pouch this species is easily distinguished from the other members of the section Phragmipedium.
The staminode is arrow shaped. The lateral lobs are arching backwards and the middle lob is narrow tongue-shaped, a little rounded at the end. This middle lob also has some hairs on both edges.
Unlike to other species Phrag. lindenii has a third fertile anther that is in direct contact with the stigma.

Habitat : This species grows at the altitudes between 1400 and 2500 meters. It's growing locations are quite variable. It grows in-between rocks and gravel, under trees in humus and moss cushions which are constantly wet, as well as on dead with moss overgrown tree stumps. So this species grows epiphytic, semi-lithophytic as well as terrestrial. It always grows together with mosses and ferns at places where a constant moistness of the growing medium is guarantied.
When it comes to light this plant grows in various places but never in full sun conditions. They seem to prefer semi-shaded locations. The temperatures in summer are between 13 and 27 °C, while in winter the temperatures can be as low as 10 °C.

Distribution : Venezuela, Colombia and Ecuador.

Flowering season :

Chromosomes : 2n = 28 (Karasawa, 1980; Wimber, 1983).

History : Jean Linden discovered this new species in June 1843 at lake Maracaibo in the territory of the Chiguara Indians at an altitude of 2800 meter. 1846 Lindley described it as Uropedium lindenii in Orchidaceae Lindenianae. In the years after that it was also found in the province of Pamplona and the province of Ocana. In the later Warszewicz found it growing in the savannas on trees and on rocks at altitudes between 1600 and 2300 m. In 1853 Wagener found it again at the same location as Linden did.
In the beginning the plants which were brought to Europe were sold at very high prices. Meanly because most of the plants dried out and died during transport from South America. In April 1850 the first plant flowered with Pescatore in La-Celle-Saint-Cloud near Paris, where gardner Lueddemann cultivated them successfully.
The genus name Uropedium didn't take hold because it was just used for this so called monstrosity and could therefore not be used for the other related species. 1870 van Houtte moved this species to the genus Cypripedium. After which Nichols classified it as Selenipedium in 1887. It wasn't until 1975 that Dressler and Williams gave it the currently used and recognized name Phragmipedium lindenii. This peloric species was long time seen as just an odd form of Phrag. caudatum, but not only does it lack the pouch, it also has a differently shaped staminode which looks more like Phrag. caudatum var. wallisii. It also has a third fertile anther. All this justifies its classification as a separate species.

Comments : A remarkable fact is that with all hybrids made with Phrag. lindenii there is a pouch present.

Hybrids :
   Phrag. lindenii
      x Phrag. caudatum = Phrag. Mauricianum
      x Phrag. lindleyanum var. sargentianum = Phrag. Louis Gaucher
      x Phrag. longifolium = Phrag. Macrochilum
      x Phrag. Calurum = Phrag. Penelaus
      x Phrag. Conchiferum = Phrag. Clonius

For a long time hybrids involving Phrag. lindenii did not have any official meaning since lindenii was recognized as a variety of caudatum.
