Section Dovusrrvu. 
30. Vanita Porrat, Reichb. f. in Linnea, xli. (1877) p. 66; 
sepalis petalisque lineatis acutis; labello cum columna connato 
antice libero expanso latissime dilatato trilobo, lobis lateralibus, 
rotundatis antice crispis, intermedio triangulo crispo omnibus 
atroviolaceo marginatis et venis insilientibus atroviolaceo pictis, 
lined latiuscula pilorum lamellarumque retrorsarum in lined 
labelli media. 
Hab. Santo Domingo, Potteau. 
Only known from description, which is very imperfect, and 
contains no reference to the affinities of the species, whose 
position therefore remains doubtful. 
DovustFuL oR ExcLupDeD SPpEctEs. 
Vanilla acutifolia, Lodd., Cat. ex W. Baxt. in Lond. Hort. 
Brit., Suppl. 1. p. 655. Name only. 
V. angustifolia, Wilid., Sp. Pl., iv. (1805) p. 121 (Epiden- 
drium domesticum, Linn., Sp. Pl., ed. I. p. 952), based upon 
Angurek Warna, Kempf. Amen. (1712) pp. 867, 869, fig. 1, 
must probably be excluded from the genus. 
V. axillaris, Mill., Gard. Dict., ed 8 (1768), n. 2, et in errat. 
A doubtful species, probably does not belong to the genus.

SuppLEMENTARY Nore. 
Since the above was read, additional material has come to 
hand, enabling the following species to be described :— 
13a. V. crenutata, Rolfe; caulibus subgracilibus; foliis 
petiolatis elliptico-oblongis abrupte acuminatis; racemis brevi- 
bus multifloris; bracteis late triangulari-ovatis subobtusis 
concavis ; sepalo postico lanceolato-oblongo subobtuso concayo
