Phragmipedium section Lorifolia (Kraenzlin)Garay
in Orchid Digest 43(4): 141, 1979.

Basionyn :
   Cypripedium section Lorifolia Kraenzlin in Orchid Gen. et Sp. 1: 37, 1897.

Synonyms :
   Paphiopedilum section Lorifolia (Kraenzlin)V.A. Albert & Börge Pettersson in Lindleyana 9(2): 137, 1994.

Type species :
   Phragmipedium longifolium (Rchb. f. & Warsc.)Rolfe.

Characteristics : The basic characteristics for the section Lorifolia are, the petals which are approximately two to three times as long as the sepals; these petals are fully grown when the flower opens; the lip (pouch) shows a pair of hornlike outgrowths at both sides of the lip opening; and the flowers open successively. It's rare to have two flowers open at the same time.

Species : This section of the genus Phragmipedium contains up to thirteen taxa, depending on the classification. Most of these taxa are very difficult to distinguish from each other. In some of the classifications new combinations were used without officially recombining them. As did for example Fortin (1975) and Cash (1991), who both did not give the basionyms (the name first given to a taxon with a reference to the source of this first description) for the new combinations they used. Giving the full basionym is required when officially renaming a taxon.
Without any problems seem to be the classification of the species Phrag. longifolium, Phrag. boissierianum, Phrag. vittatum and the later in 1988 described Phrag. hirtzii. The classification of Phrag. hartwegii is still under debate. A relatively new taxon is Phrag. chapadense which was described in August 2000 by Roberto Takase and Marcos A. Campacci. The latest addition to this section was described in 2003 by Robert-Jan W. Quené and Olaf Gruss as Phrag. brasiliense.
