long, pale green, thick and fleshy, its base bearing two filiform processes, 
about an inch long, which enter the hollow of the lip, and are curved 
or flexuose: the column itself is semicylindrical, tapering upwards into 
an acuminated and unguiculated point, to the underside of which the 
large anther-case is fixed, which takes the form of the part to which it 
is laterally applied, is broadly subulate, and at its lower part within 
bears two cells. Pollen-mass exactly as in C. tridentatum of this work. 
Stigma anterior, subquadrate, concave, viscid. 
I have here the great satisfaction of figuring another fine 
and new species of Catasetum, which blossomed in the stove of 
our Botanic Garden in November 1824. The plant was re- 
ceived from Baron Dr SHacx of Trinidad, whose recent de- 
cease has deprived our noble garden of one of its most valuable 
and liberal contributors. This is the second species of that 
suberb genus which had been introduced by that gentleman to 
our gardens; and to his memory I am desirous of dedicating 
the present individual. 
Catasetum floribundum differs from the C. tridentatum 
(t. 90, 91.) in the much larger size of its flowers, their more glo- 
bose form, and more connivent petals; and essentially in the 
much broader, acute, and by no means acuminate petals, the 
exterior of which are indeed (at least the two lateral ones) equal 
in size with the two interior ones. I may further remark, that 
here the two inner petals are of the same hue as the rest, only 
spotted within with purple, and the lip is covered internally 
with deep blotches of purple; whereas in C. tridentatum the 
two inner petals are coloured and also spotted within and with- 
out, and the lip is inside almost wholly yellow. 
From C. Claveringi of Linpuey in Bot. Reg. t. 840., it 
may be somewhat more difficult to discriminate our plant. The 
former, however, is much larger in all the parts of its flowers, 
the petals are described (though not so figured) as obtuse, and all 
of them are purple within*. The column and the filamentous 
* I fear, however, little dependence is to be placed upon colour. We have had an- 
other plant of Catasefum from Trinidad, which flowered in the stove of our Botanic
