sepal, and is quite unique in structure. B. Weddellii, 
Reichb. f. (t. 7958), from Brazil, has a very curiously marked 
and delicately mobile lip. Other interesting peculiarities 
characterize B. auricomum, Lindl. (t. 7938), B. comosum, 
Coll. & Hemsl. (t. 7283), B. macranthum, Lindl. (t. 7208), 
B. Eriessoni, Kranzl. (t. 8088), B. crenulatum, Rolte 
(t. 8000), B. reticulatum, Batem. (5605), and B. Dayanum, 
Reichb. f. (t. 6119). 
The species now figured, if less remarkable in structure 
than several of the preceding, is more showy in colour, and. 
promises to be a very attractive garden plant, the dark 
purple lip forming a striking contrast to the bright yellow 
sepals and petals, while the inflorescence is very graceful. 
It was introduced by Messrs. Sander & Sons, St. Albans, 
about two years ago, and flowered at the Royal Botanic — 
Garden, Glasnevin, in February last, when it was sent to 
Kew for determination by Mr. F. W. Moore, A.L.S.
