Resedaceae
Encyclopedia
Resedaceae is a family of generally herbaceous
dicotyledon
ous plants comprising some 70 species in six genera:
Recent molecular studies suggest that Oligomeris, Randonia and Ochradenus all arose from within the ranks of Reseda. This would imply that only three genera should be recognised, although as yet no nomenclatural changes have been made.
The family includes annuals
, biennials
and perennials
and is distributed in temperate
to sub-tropical regions of the Europe
, western Asia
, the Middle East
, North America

.
Resedaceae was placed under the Cronquist system
in the order Capparales

places it in the order Brassicales

Biennial plant
A biennial plant is a flowering plant that takes two years to complete its biological lifecycle. In the first year the plant grows leaves, stems, and roots , then it enters a period of dormancy over the colder months. Usually the stem remains very short and the leaves are low to the ground, forming...
