inherited from its parents our plate shows the latter, in the small frame at 
the right : the superior flower is C. Spicerianum; the inferior is the common 
form of C. insigne. ; 
We may recapitulate the distinctive features of these two species in the 
following manner : — C. insigne has light-green leaves, the bract of the same 
length as the ovary, the upper sepal broadly ovate rounded, has a green ground 
excepting the edge and is thichly spotted with purple, the lower sepal larger 
than the lip, the petals are large with wavy edges, slightly tinged with numerous 
brown-purple longitudinal lines, the staminode is almost quadrangular, yellowish, 
with a strong callus towards the centre. 
C. Spicerianum is notably smaller in every part, especially the flower; the 
leaves are dark green; the bract is much shorter than the ovary; the upper sepal 
is very broad, obovate-romboid, white with a bright-purple median vein, the 
lower sepal is notably smaller; the petals are relatively smaller, rather crisped, 
with one median purple line; the staminode is rounded, undulated, violet-purple 
‘margined with white. 
If we compare the seven forms of C. Leeanum which our plate figures 
with their parents, we remark in all, more or less, the trace of the median 
purple stripe on the upper sepal and petals of C. Spicerianum; most of them 
have also on the upper sepal the small purple blotches of C. insigne ; two of them 
have the upper sepal more rounded than the latter; the others more obovate, 
like the former. The first form to the left in the upper row is the one which 
most resembles C. Spicerianum; but the shape of the upper sepal and the 
staminode remind us strongly of C. imsigne. The colouring of the four others 
is also most like C. imsigne. As to the two upper ones, the one to the right 
on account of its golden shade, resembles C. Engelhardtae variety, but the 
upper sepal is much less blotched; the one to the left, remarkable for its 
size is strongly allied to C. Yvonnae. They are all superb plants.
