Spathoglottis elobulata J. J. 8.

One flower. Ovary four-grooved. Two lips opposing one another 
with outstretched and embracing sidelobes; these constituting 
the inner whorl. The outer, alternating, whorl consists of two 
unequal parts: one, the biggest, pink all over, strongly concave, 
the other also concave in its middle portion which is light pink 
but on either side with a convex-concave wing, yellowish white 
and somewhat pink. 
Is this part simple or compound? Mr. Smirn thinks it composed 
of one petal and two sepals. According to his opinion the flower 
consists of three sepals, one petallike lip enclosed by two of the 
sepals, two lip-like petals and one (unpaired) sepal. 
Personally I am inclined, also in connection with the four- 
grooved ovary, to look upon this flower as a dimerous one with 
two lips and two sepals of which one is peculiarly abnormal. 
Column thin, compressed at top, two-lobed, sticky, Anther 0.

The paired sepals show various degrees of coalescence. While 
in some flowers the sepals are quite independent, the coherence 
grows by little and little to an indented synsepalum.

' Branch of a leafy stem (fig. 14). The lower portion bears over 
a length of 20 c.M. tubular sheaths. Next comes a portion with 
five ditto sheaths which bear tapering blades pressed against 
the stem (normally distant). Then follow sheaths only whereupon 
the branch passes to a normal inflorescence. Under normal
