MR. R. ALLEN ROLFE ON THE GENUS VANILLA. 453 
Sepala et petala 14-1$ poll. longa. Labellum 14-13 poll longum. 
Columna 10 lin. longa. Capsula 5 lin. longa. 
Readily distinguished from V. inodora, Schiede (V. aromatica, 
Sw.), with which Lindley and subsequent authors have con- 
fused it, by its terminal inflorescence, with large leaf-like bracts, 
narrower sepals and petals, and other characters. The fruit is 
not aromatic. 
6. Vanitua acuta, Rolfe ; caule crassiusculo ; foliis breviter 
petiolatis elliptico-oblongis ; racemis axillaribus brevibus 
paucifloris flexuosis ; bracteis ovatis acuminatis ; sepatis petal- 
isque oblongo-lanceolatis acutis; labello basi coluamne adnato 
trilobo, lobis lateralibus oblongis, lobo intermedio ovato-oblongo 
subobtuso ; disco ecristato nervis tribus incrassatis apice rugu- 
losis; columna clavata. 
Hab. Surinam, Kappler! A drawing by Schomburgk (at 
the British Museum) iabelled River Berbice, British Guiana, 
probably belongs here. 
Folia 6-7 poll. longa, 3 poll. lata. Racemi 2-24 poll. longi. 
Bractew 5-8 lin. longw. Pedicelli 2 poll. longi. Sepala et 
petala 14 poll. longa, 6 lin. lata. Labellum 13 poll. longum. 
Columna 1 poll. longa. 
Allied to.the preceding, but readily distinguished by the 
oblong leaves, acuminate bracts, more acute sepals and petals, 
and by the proportionately narrower lip. The flowers are 
described by Kappler as yellow. Schomburgk’s drawing 
has greenish sepals and petals and a whitish lip, but it agrees 
so well in other respects that I think it must be this species. 
It shows an elongate-linear fruit 5 inches long. 
7. V. parvirotia, Rodr., Gen. et Sp. Orch. Nov., ii. (1881) 
p- 271; caule subgracili internodiis brevibus; foliis ovato- 
oblongis brevissime acuminatis; racemis terminalibus pauci- 
floris, bracteis foliaceis ; sepalis petalisque lanceolato-oblongis 
subobtusis; labello libero trilobo, lobis lateralibus rotundato- 
oblongis, lobo intermedio semiorbiculari margine plicato- 
undulato; disco medio crassiusculo nervis paullo elevatis, 
columnd glabra; capsulaé lineari-oblongé.—Cogn. in Mart. Fl. 
Bras., iii. pars tv. p. 151, t. 33. 
Hab. Brazil, in the forests of Parana, near Curityba, 
Rodrigues.
