his handsome and distinct species is one of the discoveries of the 
late Gustave Watts in New Granada, whence it was sent to Messrs. 
James Verrcu and Sons, of Chelsea, with whom it flowered for the first 
time in Europe in 1875. It was then described by Retcuensacn from a sketch, 
a dried specimen, and a single living flower. It has the peculiarity of producing 
both terminal and lateral inflorescences, on which account ReIcHENBACH made 
of it a new section of the genus, under the name of Acropleuranthium. 
Though at first thought to be a comparatively dwarf species it is now known 
that large plants attain a height of three and four feet. The stems are erect 
and reed-like, leafy throughout, and the sheaths rugose and spotted with brownish- 
purple. The leaves are from three to five inches long, by about an inch broad. 
The racemes, which are clothed with sheathing scales at the base, bear from 
two to four fragrant flowers, with golden-yellow segments spotted with crimson- 
purple, and a broad four-lobed white lip with radiating purple lines and a yellow 
disc. It is rather variable in colour, as the spots are sometimes absent from 
the sepals and petals, and amount of purple veining on the lip varies conside- 
rably in different individuals. 
When well grown, as it is in the collection of M. A. Van Imscuoor, 
the possessor of the plant from which the present plate was taken, it is very 
attractive and floriferous; the individual blossoms remain a long time in per- 
fection, and it is said that a strong plant will continue to blossom almost 
throughout the year.
