468 MR. R. ALLEN ROLFE ON THE GENUS VANILLA. 
identified with Epidendrum Vanilla, Linn. (= Vanilla inodora, 
Schiede) ; then Klotzsch referred it to V. palmarum, Salzm., 
and finally, Professor Cogniaux doubtfully placed it as a variety 
of V. Chamissonis, Klotzsch (to which latter he refers Glazion, 
14302, though the Kew specimen is certainly the present one). 
That species, however, has narrower and much longer leaves, 
and narrower sepals and petals which are shorter than the lip. 
Although figured as long ago as 1827 we are still without any 
knowledge of the fruit, and consequently it is impossible to 
say whether any of the Vanillas of commerce are derived from 
it, which, however, seems unlikely. 
30. VANILLA caRINATA, Rolfe ; foliis subsessilibus oblongis sub- 
obtusis ; racemis crassis brevibus, bracteis late ovatis obtusis 
patentibus; sepalis petalisque lanceolato - oblongis obtusis ; 
labello subtrilobo obtuso subcoriaceo medio carinato, disco 
glabro cristato ; columné clavata. 
Hab. Organ Mountains, Brazil, Miers ! 
Folia 5-6 poll. longa, 11-2 poll. lata. Racemus 2 poll. 
longus. Bractes 23-32 lin. longs. Pedicelli 14-13 poll. longi. 
Sepala et petala 2-2} poll. longa. Labellum 13 poll. longum. 
Columna 1} poll. longa. 
This species is rather imperfectly known, but is distinct from 
every other in having a strong keel down the centre of the lip, 
in front of the crest. The inflorescence is fully twice as stout 
as in the preceding species, and the bracts much smaller and 
quite different in shape. The succeeding one, besides wanting 
the characteristic keel, has the lip more distinctly 3-lobed, the 
margin undulate, and the central line behind the crest much 
more pubescent.

lanceolatis acutis carnosulis ; labello obovato-oblongo trilobo

quadrato apice obcordato-bilobo apiculato lateribus plicato-
