cases, a pair of double pollen' masses resting on a crescent- 
shaped gland, without any distinct caudicula ; to them it is 
desirable strictly to limit the name. But a great variety of 
other plants have been gradually associated with them in con- 
sequence of their having the chin which so strongly marks, 
among Vandese, Maxillaria proper ; and, in fact, this chin 
must now be considered more an indication of a division of 
Vandese than of a genus. 
For example, Maxillaria Warreana , has a globular flower, 
expanded indeed, but only a little oblique, and by no means 
ringent: this I would call Warrea. 
Then those species which are near M. lentiginosa, having 
also a flower with nothing ringent about it, have an apparatus 
of a singularly rugged nature, or at least much tuberculated, 
on the lip, and a gland of an ovate form bearing two double 
pollen-masses sessile ; to these the name Promen^ea may be 
assigned. Allied to them, but widely different in the small 
roundish gland and long setaceous caudicula on which the 
two double pollen-masses are seated, is Maxillaria cristata , 
which may be called Paphinia. Another set, with a similar 
condition of gland, caudicula, and pollen-masses, but well 
distinguished by the surface of the lip, is formed by sucfy 
species as M. aromatica, macrophylla , &c. and these I would 
call Lycaste. As for Maxillaria Steelii, with its long 
thonged leaves and deficient pseudo-bulbs, it has nothing of 
the aspect of a Maxillaria, and having a pair of double 
pollen-masses sitting on a gland tapering to each end with 
the form of a gliding serpent, it may be advantageously struck 
off under the name of Scuticaria. 
These changes having been effected, the genus Maxillaria 
will remain associated with Dicrypta, Xylobium, Camaridium, 
and Siagonanthus, the true value of which I shall shortly 
endeavour to settle. 
But it is not merely as an old genus, into which far too 
much alien blood has been infused, that Maxillaria has to be 
considered. We must certainly regard it as the type of a 
Division of Vandese, to which a good number of other genera 
will have to be associated. These genera are all characte- 
rized by having the lateral sepals more or less oblique at the 
base, the consequence of which is that the flower-bud has 
alwavs, more or less visibly, a chin, and by having a labellum 
which is destitute of a spur, or of any direct approach to one.
