DORSIVENTRAL: Flattened and having a definite front and back surface, such as a blade of grass.
DOUBLE: This is used to describe flowers which have more than one row of petals; this may be because the stamens and sometimes the pistils are transformed into petals or sometimes the petals split to form several more. Semi-double flowers are those which have only partially changed. Completely double flowers have lost their reproductive organs and are therefore unable to produce seeds. These flowers usually stay fresh longer than single flowers when cut. Double flowers are seen in the wild once in a while, but are mostly developed varieties.
