Sumatra: West coast, Korintji Peak, 2100—2400 m., in forest. 

 (H. A. B. BiiNNEMEljtR iirs. 9661 pp., Q747 pp., 9895 pp., 9901 pp., 10469 

 pp. (only flowers in alcoiiol ; I suppose that tliis really beloiigs to n. 9747), 

 April and May 1920). 



This seems to be a somewhat variable plant, if indeed ail the numbers 

 cited above belong hère. 



It differs from C. Cccillae RCHB. F. in the long bracts, the divided 

 midlobe of the lip with longer rows of warts, and the short clavate spur 

 not widened at the base, from C. longibracteaia RiDL. in the narrower 

 segments of the lip, the rows of warts at the base of the lip, the clubshaped 

 spur, from C. vcratrifolia R. Br. in the long bracts, the less divided mid- 

 lobe, the longer rows of warts at the base of the lip, the puberulous column. 



N. 9901. differs in the midlobe being narrower at the base and its 

 lobes partly covering one another. In n. 10469 the séries of warts are 

 hardly produced on the base of the midlobe. 



As ail the numbers were mixed the colour of the flowers remaiiis 

 doubtful. 



It might be an intermediate form between C. longibracteata RiDL. and 

 C. criimenata RlDL More exact observations are désirable.

Aniblygiottis pilosa De Vr. ex Lndl. (Folia Orch. Cal. (1854), 11) 

 = Preptanthe-villosa RCHB. F. in Bonpl. V (1857, 42) is, as the figure in 

 the Leiden Herbarium shows, Calanthe vestita WALL. var. sumatrana 

 SCHLTR., and C. sumatrana BL. ex BOERL. (in Midden-Sumatra IV (1884), 

 33, t. V) is, I suppose, C Ceciliae RCHB. F.
