rowed portion; the lobules are at right angles to the 
median axis, with acute apices, slightly retrorse and fal- 
‘ate-oblanceolate in outline and from tip to tip much ex- 
ceed the lateral lobes in spread; dise with two basal calli 
and a central somewhat rhombic thickening which ex- 
tends upon the mid-lobe. Column clavate, extending to 
the base of the lateral lobes of the lip. 
Critical examination of the material referred to 1’. 
paniculatum and EF. floribundum leads us to believe that 
these concepts are not separable from each other although 
Lindley and Reichenbach kept them distinct. Lindley 
in Folia Orchidacea placed them in different sections of 
the genus, 12. paniculatum in Amphiglottium (Polyclada) 
and JZ. floribundum in Kuepidendrum (Paniculata). It is 
noteworthy, however,that Lindley cites Funck & Schlim 
1448 under both species, and under 12. floribundum makes 
the following comment:''.A great branching green-flow- 
ered species, very much like /?.paniculatum and lavum, 
differing however in the want of spathaceous bracts.” 
We take occasion to note here that we do not feel that 
KH lavum belongs to this alliance and that the presence or 
absence of spathaceous bracts has not proved to bea valid 
character upon which to separate species in the genus 
Kpidendrum. 
From each of these basic groups or species (17. pasic- 
ulatum and Id. floribundum) there have been segregated, 
from time to time, many so-called species and varieties. 
However,since we are unable to separate the basic groups, 
it is obvious that segregates from them are open to ques- 
tion. Of the several parts of the plant showing the varia- 
tions upon which segregation has been based,the labellum 
(especially the mid-lobe) is the one most often emphasized 
by authors. ‘The differences in this part, however, are 
very inconstant and vary with regard to length and 
breadth of the lobules, type of sinus or isthmus between
