470 MR. R. ALLEN ROLFE ON THE GENUS VANILLA. 
1879, and both the fruits have opened, yet they retain a distinct 
aromatic perfume, though whether the species has any economic 
value is uncertain. 
34. Vaninta Cuamissonts, Klotzsch, in Bot. Zeit., iv. (1846) 
p. 564; habitu Vanille planifoliw, caule crassiore; foliis longi- 
oribus et angustioribus marginibus revolutis ; bracteis oblongis 
obtusis; sepalis petalisque lineari-lanceolatis ; labello anguste 
oblongo margine crenulato, nervis crassiusculis minute 
crenulatis, crist& penicillata, tubo basi pubescente.—Cogn. in 
Mart. Fl. Bras., iii. pars tv. p. 148, t. 32. ; 
Folia 7-9 poll. longa, 1-14 poll. lata. Racemi 33 poll. long. 
Bractese 3-5 lin. longee, 14-24 lin. late. Sepala et petala 
2¢-23 poll. longa. Labellum 2% poll. longum. 
Hab. Brazil, in ingsulé Sant& Catherina, Chamisso. S. Brazil, 
Eschscholtz. Environs de Rio Janeiro et d’Ouro Preto, Glaziou, 
15661! 
Easily distinguished from the preceding by its long and 
narrow leaves, more slender inflorescence and the lip longer 
than the sepals and petals. The fruitis unknown. laztou, 
14302, cited here by Professor Cogniaux, belongs to V. Vellozit, 
Rolfe. 
35. V. Rurztana, Klotzsch, in Bot. Zeit., iv. (1846) p. 563; 
caule crasso; foliis lanceolato-oblongis subacutis breviter 
petiolatis. 
Caulis 3-5 lin. latis; internodis 3-5 poll. longis. Folia 
5-7 poll. longa, 1-12 poll. lata. 
Hab. Peru, Ruiz & Pavon ! 
A species with very distinct habit, but nothing is known 
about the inflorescence or 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 (the one other known from Peru), or to some other 
species, there is no means of determining. 
36. V. ENsIFOLIA, Rolfe, in Kew Bull. (1892) p. 141; scandens 5 
caulibus elongatis sulcatis lmvibus; foliis petiolatis enst- 
formibus y. elongato-linearibus subattenuatis acutis breviter 
petiolatis ; racemis abbreviatis, floribus subfasciculatis, bracteis 
lanceolato-ovatis acutis; sepalis lineari-lanceolatis acutis ; petalis 
subsimilibus subfalcatis nervo medio paullo incrassato ; labello 
elliptico-oblongo crenulato.
