It- constitutes, along with some other South American 
plants with a similar habit, a genus representing among 
Vandeze Isochilus in the Epidendreous section ; and distinctly 
characterized by its flowers having the calyx and corolla of 
Specklinia, combined with pollen masses of a very unusual 
structure. When four pollen masses are combined in pairs, 
they are usually pressed so close together that the one is 
flattened against the other, and they seem as if in reality 
each pair were produced by the slitting of one; in this genus, 
on the contrary, each mass is rounded and separate from its 
neighbours. 
When I published this plant in the work above quoted, 
under the name of Cladobium violaceum, I had not seen the 
late parts of Póppig and Endlicher's Nova genera, which ap- 
peared in the end of 1835; and consequently I was unaware 
of the genus having been already named Scaphyglottis in 
that work. Perhaps as the name Cladobium was in circu- 
lation, from me, so long since as February, 1835, I might on 
that ground set up a claim to priority, and preserve it; 
but as Mr. Pöppig has described several species, -1 think 
the interests of science will be best consulted by cancelling 
Cladobium and adopting Scaphyglottis. 
Of the dissections, 1. is an entire flower seen in profile 
and magnified ; 2. is a side view of the column and lip; 
3. a view of the lip from above; 4. a set of pollen masses 
with their gland.
