The genus Scaphosepalum consists of a small group of 
Orchids, the species of which have been referred, some 
to Masdevallia, some to Pleurothallis, and some to both, 
but which present characters in common foreign to these 
genera, and they further agree in habit inter se. The 
founder of the genus, Professor Pfitzer, of Heidelberg 
(author of the “ Morphologische Studien, ueber die Orchi- 
deen bliithe”” and “ Natiirlichen Anorndnung der Orchi- 
deen’), established it upon Masdevallia ochthodes, Reichb. 
f., & M. (alias Pleurothallis), verrucosa, Reichb. f. ; and it 
has been adopted by Mr. Rolfe in a very good article 
published in the journal of Botany cited above. In this 
article Mr. Rolfe includes under Scaphosepalum seven other 
plants hitherto for the most part referred to Masdevallia, 
amongst which is the M. gibberosa, Reichb. f., figured at 
t. 6990 of this magazine; including the subject of the 
present plate, and S. antenniferum, Rolfe, a _ Species 
‘Tecently described in the “‘ Gardener’s Chronicle }; Sca-

one or more hitherto undescribed. Considering how
