It really appears as if almost every new species of the para- 
sitical orchideous plants which are now so abundantly culti- 
vated in our stoves, might likewise constitute a new genus, 
so variable are the form and structure of their flowers. I am 
far from thinking that the present individual should continue 
in the genus Pleurothallis, but it will be more easy to decide 
upon the proper place of it, and of many others of the same 
family, when we shall be able to compare the figures and ana- 
lyses of the inflorescence of several species together : on this ac- 
count I am more anxious to give correct descriptions and faith- 
ful representations, than to attempt at what might prove but 
an unsatisfactory arrangement. 
Introduced to the Botanic Garden of Glasgow, through the 
favour of our valued correspondent Baron De Schack, M. D. 
from the Island of Trinidad. It flowered in the month of 
June 1824 *

two lower petals curved and concealed by the labellum. Fig. 3. Column 
and lip. Fig. 4. Two lower and united petals. Fig. 5. Side view of 
the column, with the lid thrown back, and shewing the pollen-mass. 
Fig. 6. Front view of the column, with the anther removed, and the 
pollen-mass in the position in which it is then seen. Fig. 7' Front 
view of the pollen-mass. Fig. 8. Sack view of the same. — AU more or 
less magnified. 
* Since the above has been printed, I find a plant figured in Loddiges' Botanical 
Cabinet, under the name of Rodriguezia lanceolata, which I cannot doubt is the same as 
the one here given. It must be confessed, too, that my plant comes very near to the 
Rodriguezia secunda of Humb. et Kunth, Nov. Gen. t. 92. if it be not the very same. 
If so, according to these authors, it is only distinguishable from the genus Pleurothallis, 
by the obscurely spurred labellum.
