@A new species of Phragmipedium was described by Mr. Marcos Antonio Campacci and Roberto Takase in Brasil.@This information was supplied by Mr. Roberto Takase. Thank you Roberto.

Phragmipedium chapadense Campacci & Takase sp. nv.

Terrestrial plant with short rhizome, witish roots, glabrous, with about 3,0 mm in diameter. Coriaceous leaves, in the uper side slightly canaliculate, underside carenate, reaching 50,0~ 60,0 cm in length and 2,0~3,0 cm in width, dark green in the surface and ligther in the underside with no yellow margin.The inflorescence is brown, reaching 50,0 cm in hight, pilose bearing, light green bracts of 10,0 cm. Floral bracts longer than ovary, 6,0 ~7,0 cm in size, also light green in color with a darker green venation in the surface.
Successive flowers (3 to 5) with 10,0 cm total vertical length by 13,0 cm total horizontal length. The dorsal sepal is ovate-lanceolate in shape, measuring 5,0 ~ 5,5 cm long by 1,5 ~ 1,8 cm wide, acuminate, yellow-green in color with brown venation, and in the back side is darker than the synsepal. The synsepal have the same color as the dorsal sepal, also veined, but darker in the border, measuring 4,5 ~ 4,8 cm long by 3,2 ~3,4 cm wide and slightly undulated in the border. Linear-lanceolates petals, longer than the sepals, measuring 9,0 cm longer by 0,7 ~ 0,8 cm wide near the base and geting thiker to the end. The color of the petals is ligth green in the center with red margin bearing paralel stripes of red-brown color. Near the base they are undulated and pilose, with one or two full twists. The apices of the petals are pilose with intense red color. They held a 45 position below the horizontal line.
The lip is longer than the synsepal, measuring 5,0 ~5,2 cm long by 2,4 ~2,5 cm wide, sacate in general obovoid. The pouch is wider than the infolded side lobes, chestnut greenish in color. It bears two auricles in the margins of the aperture. The side lobes (ostio) are pale green spotted with small redish-brown dots, without other acessory spots. The joint of the side lobes is brigth green in color. Elliptic staminode, measuring 0,6 cm long by 1,0 cm wide, brigth green with short thik redish hairs in all the uper side untill the collumn and the external border turned backside. The collumn is pubescent and has 0,4 ~0,5 cm long.
HABITAT : It grows in open grassy fields and depressions over seepage covered by a shrubby vegetation.
DISTRIBUTION : Chapada dos Veadeiros, State of Gois, Brazil. At an altitude of 700 - 900 m.
FLOWERING SEASON : In Brazil this species flowers at the end of summer.
COMMENTS : This species was usually confused with Phrag. vittatum (Vell.)Rolfe by collectors, but differs from the latter in many points, i.e. appearance of the plant, being considerably smaller in size, having a larger, near elliptic staminode etc.; whereas Phrag. vittatum has an apparent triangular staminode. Petals are not pendent downwards like those of Phrag. vittatum, but deflected at about 45 degrees angle from horizontal. Besides, the flower scape is always shorter and darker.
The flowers are somewhat similar to those of Phrag. hartwegii (Rolfe)Pfitzer from Ecuador concerning coloration of the petals, its narrow infolded side lobes, the shape of the flower bract and the colour and form of the ovary. However the differences from Phrag. hartwegii are clear: In Phrag. chapadense the pouch is wider than the infolded side lobes, while in Phrag. hartwegii these two parts are equal in width; the staminode of Phrag. chapadense is elliptic in shape and black hairs on the upper margin are conspicuous, whereas in Phrag. hartwegii subcordate, a little smaller and hairs, being located further backward and hence not so remarkable. Colour of the pouch of Phrag. chapadense is maroon, while greenish or yellowish in Phrag. hartwegii. Further, the size of Phrag. hartwegii is generally larger than that of Phrag. chapadense.
