Origins of morpho- words

The Roman god of sleep is Somnus; so, when we are sleepy, we are "somnolent". Sleep walking is "somnambulism" which in Latin means exactly the same thing; that is, "sleepwalking".

The son of Somnus is Morpheus, the god of dreams, indicating that sleep gives birth to dreams. Morpheus goes back through Latin to the Greek word for "form" or "shape" because dreams are forms and shapes developed in the mind while sleeping.

zygomorphic
Capable of division into symmetrical halves by only one longitudinal plane passing through the axis.

Many flowers are symmetrical in only one plane (that is, symmetry is bilateral) and are termed irregular or zygomorphic (meaning yoke-formed or pair-formed).

In irregular flowers, other floral parts may be modified from the regular form, but the petals show the greatest deviation from radial symmetry.

Examples of zygomorphic flowers may be seen in orchids and members of the pea family.

zygomorphism
Bilaterally symmetrical; a reference to organisms or parts divisible lengthwise into similar or symmetrical halves.
zygomorphous
1. Symmetrical bilaterally; said of organisms, or parts of organisms, capable of division into two symmetrical halves only in a single plane.
