Type(s) :
Etymology : This entity is named after Karlheinz Bader from Bargstedt, Germany. He introduced a plant of this small new variety to the D.O.G.-judging committee at 12-Nov-1994 in Ingolstadt, Germany. This plant was awarded a bronze medal. (D.O.G. = Deutsche Orchideen-Gesellschaft = Germany Orchid Society)
Plant : The plants of this variety differ in all aspects in size from the typical hartwegii.
Leaves : The leaves are 28 cm long and 1.1 cm wide.
Inflorescence : This is approximately 25 cm long.
Flower : The dorsal sepal is approximately 3.2 cm long and 1.3 cm wide. The synsepalum is about 2.6 cm long and 2.3 cm wide. The petals have a length of about 5.8 cm and a width of about 0.6 cm. The labellum or pouch is approximately 3.5 cm long and 1.4 cm wide. The staminode is about 0.5 cm high and 0.65 cm wide.

History : Phrag. longifolium f. hartwegii is very rare in cultivation. In 1994 plants labelled as Phrag. hirtzii came in circulation which looked very much like Phrag. longifolium f. hartwegii. The flowers however were much smaller and the leaves resembled those of Phrag. caricinum.
One of these small plants was entered for judging at a show of the German Orchid Society (Deutsche Orchideen-Gesellschaft) in Ingolstadt at 12-Nov-1994, and won a bronze medal.
This plant was so different from the typical hartwegii, not only in growth but especially in the size of the leaves and flowers, that it was decided that a description as variety was required.
Comments : Analysis of specimen of f. baderi and artificially made hybrids has rejected the idea that this variety might be a natural hybrid of Phrag. longifolium f. hartwegii with Phrag. pearcei, Phrag. hirtzii or Phrag. caricinum (Röth and Gruss, 1997).
Very closely related to hartwegii is Phrag. longifolium. Of this later species there is also a small growing variety known to science; Phrag. longifolium f. gracile.
