Type: Colombia: Depr. Cauca, without precise locality, 
LINDEN S5.n. 
The genus Osmoglossum is new to Colombia, and plants must 
be exceedingly rare, for I have not yet seen a specimen col- 
lected in the wild. It appears to be close to O. Egertonii 
(Lindl.) Schltr., but differs in the pandurate lip and the fim- 
briate column-wings. 
Osmoglossum panduratum Garay, sp. nov. 
Epiphytica, usque ad 50 cm. alta; rhizomate repenti, valida; 
pseudobulbis approximatis, anguste ovoideis, compressis, 
2-foliatis, usque ad 9 cm. longis, 3 cm. latis; foliis oblongo-lin- 
earibus, loratis, acutis, usque ad 42 cm. longis, 1.5 cm. latis; 
inflorescentiis erectis vel suberectis, laxe paucifloris, usque ad 
30 cm. longis; pedunculis ancipitibus, paucivaginatis; bracteis 
lineari-lanceolatis pedicellis aequilongis, usque ad | cm. lon- 
gis; floribus niveis, columna pallide rosea, callo aurantiaco, 
brunneo-punctato; sepalo postico lanceolato-elliptico, abrupte 
acuminato, 14 mm. longo, 5 mm. lato; sepalis lateralibus ter- 
tiam partem basalem inter se connatis, oblique oblongo-lanceo- 
latis, abrupte acuminatis, 14 mm. longis, 4 mm. latis; petalis 
late ellipticis, obtusis vel subacutis, 15 mm. longis, 8 mm. latis; 
labello sessili, pandurato, a medio replicato, basi truncato, 
antice ovato, abrupte acuto, disco callo W-formi, valde car- 
noso a basi usque ad medium ornato, explanato 13 mm. longo, 
8 mm. lato; columna generis, clinandrio denticulato; ovario 
cum pedicello geniculato. 
Ecuador: without precise locality. Imported and grown by 
JOHN STACY s.n.! type! (AMES). 
This new species is closely related to O. pulchellum differing 
from it in its much smaller flowers, and in the shape of the lip. In 
O. pulchellum the constriction of the lip is in front of callus, the 
terminal lobe is larger than the basal part, subquadrate to subro- 
tund, truncate in front and the callus occupies % of the disc of 
lip. In our plants the constriction of the lip is on the sides of 
callus, the terminal lobe is smaller than the basal part, ovate, 
abruptly subacute and the callus occupies % of the disc of the lip.
