CLASSIFICATION 181 
lengths corresponding to the stamens, i.e. if one flower has short 
and long stamens it will have styles of medium length, etc. (see 
diagram on page 113). Honey is found at the base of the tube 
formed by the filaments. An insect gets pollen on two parts of his 
proboscis, and when he enters another flower the pollen will be 
put on to the stigma of corresponding length. Self-pollination 
being almost impossible in this flower, reproduction oecurs in 
two other ways. The plant produces cleistogamous flowers as 
well as the trimorphic ones; it also reproduces itself vege- 
tatively. The fruit is a capsule, the seed has a fleshy aril, and 
by its sudden inversion it is shot out.
