5-lamellate callus, whereas N. rhodoneura is noted as 
having a 6-lamellate callus—i.e., four central lobes with 
a pair of outer calli. The actual truth of the matter, as 
shown by acritical examination of the type of NM. Man- 
doni, is that the callus at the base of the flaring anterior 
portion of the lip has four distinct lobes with a more or 
less developed shorter median portion connecting the two 
pairs of side lobes—a feature which is obscure or absent 
in the freshly boiled flowers but which becomes more 
distinct as the flower dries out. he two series of central 
lobes described and illustrated for N. rhodoneura are 
explained by the fact that these median callus-lobes are 
sometimes lightly indented in the middle. 
The type of N. ldatilabia differs from the other forms 
of this variable species only in having somewhat broader 
and more ovoid pseudobulbs. Its flower, and especially 
the lip, corresponds well with the type of N. Mandoni, 
but the color is noted as red or red-orange rather than 
purple. 
Neodryas reniformis does not appear to differ in any 
noticeable degree from N. rhodoneura.
