the different genera of this order were established upon any 
thing like permanent characters. Since this publication, the 
labours of Roxpures, of Dryanper, and Brown, have 
vastly increased our knowledge of the species, and facilitated 
our right understanding of the parts of fructification upon 
which the generic distinctions must be founded. 
The synonym of Grospa sylvestris of Rumpuius, above 
referred to, though always quoted as belonging to our plant, 
appears to us extremely dubious; neither the laboured de- 
scription nor the figures. seeming to us to apply to it. 
This species, as well as calcarata, has the spur-like 
appendixes at the base of the nectarium or labellum ; indeed 
Mr. Brown observes, that these are generally if not always 
present in the one-lipped plants of this order, and-are’ con- 
‘sidered by him as the rudiments of the two lateral lacinie of — 
the internal limb of the corolla. In Arpinia mutica of 
Roxgureu, however, they are said to be entirely wanting. ©
