History : The variety was roughly described in the 18-hundreds. The name was given to it by Veitch in ,,A Manual of Orchidaceous Plants" Vol. II: 65. Rolfe mentioned it in ,,The Gardeners' Chronicle" in 1890. He referred to Veitch's description and wrote: ,,There is a variety of C. longifolium named gracile, more slender in all its parts, and of a paler colour, and bracts more compressed".
A far better and more precise description was given by Kohji Karasawa in 1987 in his Orchideen Atlas 1: 214. The picture that accompanied this description clearly showed it's relationship with Phrag. longifolium.

Comments : Very closely related to Phrag. longifolium is Phrag. hartwegii. Of this later species there is also a small growing variety known to science; Phrag. hartwegii var. baderi.
