This plant is described as coming from Guatemala. Perhaps 
the garden specimens we observed in Consul Schiller’s and Mr. 
W. W. Saunders’ stoves came from there. They were received 
from the late Mr. Skinner, who sometimes also introduced Costa 
Rica plants. The very numerous specimens in our herbarium 
are from Costa Rica, Cartago, 5000’; Irusa, 8—9000’, Oersted! 
Cartago, 22.3, 1857, Wendland! Nice small specimens are col- 
lected by Ruiz and Pavon! The plant does not occur among 
Dr. Bernouilli’s rich Guatemalese collections. A flower given to 
us by Dr. Lindley is marked ‘ Guatemala.” 
The plant forms dense tufts, the bulbs rising near one another 
from the thin rhizomes and the thin filiform flexuose roots, now 
and then rough on their surfaces. The fusiform pseudobulbs, now 
compared with shanks, have a much thinner stalk, and consist of 
from two to three joints. ‘The very base of the stalk is generally 
thickened in a little bulbous pyriform mass. The inferior sheaths 
soon lose their articulated triangular laminar apex. Leaves gene- 
rally two, occasionally one or three, linear, with an equally or 
unequally bidentate apex, of a very firm texture, light green. 
Inflorescence terminal, straight, racemose, bearing two, three or 
only one flower. The peduncle is thin and firm. Bracts trian- 
gular, acute, nearly half the length of the whitish stalks to the 
thicker green ovaries. ‘The chin of the flower is blunt and very
