Sicyoideae 
In the Sicyoideae, the distinguishing characters of which 
are to be found mostly in the androecium, one is impressed 
by the variations in the forms of the pistillate flowers. Coc- 
cinta presents a case in which the structure of the ovary is 
not essentially different from that of some of the Cucurbiteae. 
Not only are the developmental features similar, but one 
finds in a transverse section of a young ovary that it is dis- 
tinctly tricarpellary, and furthermore, that on each placental 
border, not one only, but two rows of ovules are present. 
This condition is quite different from that which is to be 
found in other members of this tribe, viz., Szeyes and A@z- 
crampelis. 
The pistillate fowers of S7cyos are borne in dense clusters, 
several flowers being sessile at the end of a common peduncle. 
Sections of the growing tip of a flowering shoot pass through 
several of these clusters at various stages of development. 
As the flowers project in all directions from the end of 
the peduncle, it follows that they appear in the preparation 
sectioned in many different directions. The pistillate inflo- 
rescence first appears near the growing point of the shoot in 
the form of a blunt outgrowth in the axil of a leaf-rudiment. 
This outgrowth soon develops on its surface numerous pa- 
pilla-like elevations which continue to increase in height. 
These are at first rounded at the end, but later the end be- 
comes flattened perpendicularly to the axis. This flat sur- 
face becomes later depressed at the center by reason of the 
more rapid growth in the peripheral region, and the depres- 
sion gradually deepens into a cup. About the time the de- 
pression has reached a depth a little greater than the trans- 
verse diameter of the ovary, the corolla-lobes appear near 
the top in a circle running parallel with the upper border and 
on the inside. This is followed a little later by the appear- 
ance of three elevations a little lower down and also in the 
inside. As growth proceeds the border or rim of the cup 
becomes divided to form the calyx and the next circle of 
organs forms the corolla. The three outgrowths which arise
