his is one of the earliest known Catasetums, for it appeared as long ago 
as 1836, when it was described and figured by Lindley, under the name 
of Myanthus barbatus , in the Botanical Register. Lindley there observes : 
“ This curious new species is a native of Demerara, near the falls of Wapopekai, 
on the Massarony river, some hundreds of miles from its mouth, where it was 
found by M r John Henchman, growing in the clefts of trees in shady situations. 
It was first sent us in February last by M r Low, with whom it first flowered, but 
almost immediately after we received it from Chatsworth, and from the garden 
of M r Willmore, of Oldfield, near Birmingham. ” In the same year it was also 
figured in the Botanical Magazine , from a Demeraran specimen which flowered 
with M. Allcard, of Stratford Green, Essex, in May of that year. 
In 1841 a new Myanthus was described in the Botanical Magazine , under the 
name of M. spinosus. Its author, Sir William Hooker, remarks that it is one of 
the few Orchids which rewarded M r Gardner’s researches in the province of Cearâ, 
in the interior of Brazil. It flowered for the first time at Kew, in February, 1840. 
It was afterwards reduced as a synonym of C. barbatum by D Bindley, together 
with his own C. proboscideum , another Brazilian plant, with the remark that no
