Quoting from: Gruss, O. "A Checklist of the Genus Phragmipedium." Orchid Digest 69, no. 4 (Oct/Dec 2003): 214-41.
Phrag. caudatum: "A large number of varieties or geographical forms of this species appear in the literature, the main difference being flower color and size. In addition, several varieties have been described that today are classified as distinct species by a few authors and by the International Registration Authority of Orchid Hybrids." Phrag. wallisii: "The variety is distinguished from the normal form of P. caudatum by the following traits: staminode three-lobed, acuminate lateral lobes arching backwards; mouth of labellum yellow, spotted brown; margin of petals glabrous; smaller flowers." Phrag. warscewiczianum: "Dark green leaves shorter and wider than those of other members of the section; usually only one to three flowers; flower color is more dark brown; staminode smooth, and long trapezoid to almost rhomboid in shape; mouth of labellum is yellow-brown." --Stephen _______________________________________________ the OrchidGuide Digest (OGD) [email protected] http://orchidguide.com/mailman/listinfo/orchids_orchidguide.com
