26 CXLVIII ORCHIDEX, (J. D. Hooker.) [Luisia, 
on each side, epichile broadly triangular-ovate, column purplish, anther with 2 yel- 
lowish eyes in the centre of each half.—Assam, Benson (Hort. Veitch).— Description 
from the author l. c. Possibly the sepals longer than the petals is an error, due to the 
omission of a comma in the phrase “ sepalis ligulatis acutis petalis longioribus." 
CYMBIDIUM TENUIFOLIUM, Willd. of Thwaites mss. (C. P. 38530) is certainly not 
L. tenuifolia, Bl., having short petals and a broad lip. It is probably a new species 
near filiformis, but the specimen being solitary and only 1-füd. I leave it 
undescribed,
