? C. deformis. R. Brown, L. c. 
Hab. in N. Hollandia ; Tasmannid, Gunn, 347. (hab. s. sp.) 
The plant now described has flowers almost as regular as those of _the 
§ PENTISsEA. My specimens are from 3 to 4 inches high, and the leaf is in 
all of them unusually long for this genus. I am not certain whether this 
is Brown's C. deformis ; but from some parts of the character assigned to 
that plant I think it probably is so.

C. folio lineari caule unifloro breviore, sepalis petalisque obtusiusculis, 
labelli cuneati long? unguiculati glandulis 4-seriatis ramentaceis in-

disco glanduloso.
