Cyrtochilum undulalum HBK., I. t. 84. LO., p. 210. L. F. 7. 



This is slill unknown to me. It is said to have brown flowers spotted witb white 

 and yellow ; a lip pink outside , yellow wilhin. variegated with red and white spots ; 

 scape as high as a man. according to Kunth. It is near 0. orgyale and ventilabrum. 

 Mr. Reichenbach wlio has examined an authentic specimen, thus describes the lip 

 the form of which is imaginary in Turpins figure. Cf. infra.

16. ONCIDIUM ZEBRIiNUM Rchb. fil. in Bonpl., Ap. 1, 1854. Lindl. F. sub 16. p. 7: 



Odont. zebrinum Linn. 1849. (cf. Waip. Ann. IIL 559.) 



Undoubiedly ihis is an Oncidium, as Rchb. has now pointed out. Since the article 

 Odontoglossum was wrilten , I have received it frora the collcctions of Moritz, and 

 find il 10 be a planl wilh a straggling , twining panicle of flowers resembliiig tliosc 

 of 0. irilingue (N. 5.), but smaller. Its long lip acutely angular al ihe base, and its 

 crest are characteristic ; ihe lalter consisls of a central ridge formed of flve long 

 confluent lamellae wiih as rnany sharp teeth in front and several straggling warts on 

 either sidc.
