Hab.: Supposed to be a northern form. 



Forma, firandiflorum, Bail. Bjt. Bull. xiv. This variety has a more vigorous habit 

 than D. speciosum, var. Hillii ; the leaves often over 1ft. long and near Jtt. broad. The 

 distinction, however, is mostly in the flowers, which are of a deep yellow from first expaning 

 until they decay. Sepals IJio. long, and 3 lines broad. Petals IJ line broad. Labellum veiy 

 obtuse and barred throughout with purple.

 oblong, the end somewhat pointed, about 5in. long, 2in. broad, often concave. Peduncle with

 curving outwards, 1 to IJ line broad. Labellum, the lateral lobes loosely embracing the very 

 short column, the column in its natural position about § the length of the other segments,,
