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 Vandeae, Maxillaria proper ; and, in fact, this chin 

 must now be considered more an indication of a division of 

 Vandeae 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 woulcl 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^a 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 such 

 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. >.j_ £ 



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 ot a 

 Division of Vandeae, to which a good number of other genera 

 will have to be associated. These genera are a 11. 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.
