462 MR. R. ALLEN ROLFE ON THE GENUS VANILLA. 
perianth segments. The specimen is not in very good state, 
and the fruit is unknown. Spruce records the flowers as 
whitish-green. 
23. Wanita HAMATA, Klotzsch, in Bot. Zeit., iv. (1846) p. 563 ; 
foliis breviter petiolatis late ellipticis vel obovato-ellipticis, 
apiculatis apiculo recurvo; sepalis et petalis oblongo-lanceolatis 
subobtusis; labello subintegro obtuso crispo-undulato, crista 
appendicibus fimbriatis composit4; disci nervis ternis superne 
carinatis crenulatis. 
Hab. Peru, Ruiz et Pavon! 
Caules (sicci) 4 lin. lati; internodi 443 poll. longi. Folia 
54-6 poll. longa, 33 poll. lata. Sepala et petala 3 poll. longa. 
Labellum 2 poll. longum. Columna 1} poll. longa. 
Very distinct from every other species in the shape of the 
leaves, but nothing is known about the inflorescence and fruit. 
Humboldt speaks of a Vanilla in the province of Jaen, on the 
Upper Amazon, Peru, with aromatic fruits (Voy. Humb. et 
Bonpl., pte. 3, vol. ii. p. 437), but whether it belongs to the 
present species, to V. hamata, Klotzsch, or to some unknown 
Peruvian species, there is no means of knowing. It was 
described from a barren specimen, but a piece from Pavon at 
the British Museum (hitherto unidentified) enables the details 
of the flower to be added. 
24. V. Hosrmanni, Rolfe; caulibus crassiusculis ; foliis 
breviter petiolatis lanceolato-oblongis, breviter acuminatis sub- 
obtusis ; racemis crassiusculis subelongatis multifloris, bracteis 
oblongis obtusis vel subacutis concavis; sepalis petalisque 
lanceolatis subobtusis; labello oblongo subintegro obtuso ; disco 
basi pubescente, crist4 retrorsim hirsuta; columné clavata. 
Hab. Surinam, Hostman, 306! 
Folia 54-9 poll. longa, 14-23 poll. lata. Racemi 2-3 poll. 
longi. Bractere 3-5 lin. longw. Pedicelli 1} poll. longi. 
Sepala et petala 2-23 poll. longa. Labellam 1}-2 poll. longum. 
Columna 1} poll. longa. Capsula ignota. 
In the absence of fruit the exact affinity of this species is a 
little doubtful. The inflorescence and bracts would place it 
near V. planifolia, though the disc of the lip is not corrugated 
in front, as in that species. The leaf is also distinctly broader 
in the middle than elsewhere, as is often the case with 
V. Pompona, which is very different in other respects.
