1914] FARRELL—CYRTANTHUS SANGUINEUS 429 
The ovary is composed of three carpels. I found two different 
arrangements of their vascular bundles according to location. In 
the region of the lateral fusion of the carpels, there are three bundles 
grouped as one. All are collateral; the outer one is ectophloic, 
and the other two are so arranged that their xylem masses face 
each other (text fig. 1). The strands at the midrib of each carpel 
appear in three distinct groups; the outermost one consisting of a 
single collateral ectophloic bundle; the innermost one of two 
bundles with their xylem masses facing; and the intervening group 
composed of two double bundles, the degree of approximation of 
which differs at different levels in the carpel. One of the levels is 
shown in text fig. 2. This 
peculiarity of arrangement 
is probably due to the 
curving of the edge of the v 
carpels to form the closed 
ovary. A closer study led C V 
to an explanation of the 
different groups of bundles, 
and showed that each 
organ of the flower is 
supplied from these vascu- 
lar strands. Text fig. 3 is 
a diagram of the flower, 
the dotted line represent- 
ing the outline of the 
ovary. It can be seen that the abortion of the stigmas occurred 
opposite the region of the fusion of carpels. On tracing their 
bundles downward into the ovary, they are found to be derived 
from the primary groups in the carpel. Lower still, these bundles 
fuse with those of the flower stem. 
Noticing the frequent occurrence of stomata on the inner sur- 
face of the carpels, I was interested to know the relative number 
per unit of area in comparison with the outer surface. I found 
the relation to be as 8:5 in favor of the inner side. This is con- 
trary to what we should expect, for in the foliage leaves of Cyr- 
tanthus the stomata are more numerous on the abaxial surface.
