The preceding elaborate and most excellent descrip- 
tion, made from plants observed in India, has been kindly 
communicated to us by our valued friend Dr. Wallich, by 
whom an account of this and a second species was long 
ago prepared for publication. At that time he proposed to 
refer them to Ornithidium, remarking, however, at the 
same time, that certain peculiarities of structure, which 
had not escaped his accurate observation, ‘‘ would perhaps 
require the plant to be formed into a new genus.” 
This measure we had ourselves adopted, so long since 
as 1824, and having communicated the name now retained. 
to Dr. Hooker, the species was published in the Evotic: 
Flora, in January 1825; but at that time no knowledge 
was possessed in this country of Dr. Wallich’s MS. name. 
The genus Ornithidium, to which Pholidota is undoubt- 
edly very nearly allied, is distinguished by its labellum 
being partially connate with the column, by the column 
being taper, not round, by the anther having only two 
valves, and by its pollen masses being fixed upon a gland. 
In this last point the figure in the Hvotic Mora of Or- 
nithidium coccineum, otherwise excellent, is defective, the 
pollen masses being there represented as lying loose in 
the cells of the anther; and, therefore, as having the struc- 
ture of Malaxidez, instead of that of Vandez. 
A native of several parts of India. Dr. Wallich 
informs us, that he has found it on the mountains west 
of Ava, also high up the rivers in Martaban, and on the
