The genus Aganisia was established by Lindley in the 
Botanical Register (1839, Misc. No. 65, and 1840, t. 32) 
on a single Demeraran species (A. pulchella). Lindley says 
of the genus, “if its column were produced into a foot, 
and the lower sepals unequal at the base, it would be a 
Mazillaria.’’ To this are added by Bentham in the Genera 
Plantarum, and Reichenbach in various publications, about 
eight other species. As these present great differences in 
habit, and have never yet been all brought together in one 
work, I shall enumerate them here in the interest of 
Orchidologists. They are:—1. The above-named A. pul- 
chella with the pseudobulbous one-leaved habit of A. 
ionoptera, but with long creeping rhizome, a short scape, 
and white flowers with a yellow lip; the plant resembling 
a small Owlogyne. 2. A. jfimbriata, Reichb. f. in Gard. 
Chron. 1874, ii. 452 and 804, a native of Demerara, with 
white petals, and a blue saccate fimbriate lip. 3. A. cwrulea, 
Reichb. f. in Gard. Chron. 1876, ii. p. 226, a blue-flowered 
Brazilian species, also with a saccate fimbriate lip. 4. 4d.
