Abstract
An overview is provided over the perennial taxa in the Urtica
dioica complex in Cyprus, Iran, Iraq, Lebanon, Syria and
Turkey. The literature reports a variety of names for the taxa of this
group in this region and the recognition and taxonomic status of taxa
differ between the respective floristic treatments. On the basis of
both living and herbarium material the tentative recognition of the
following taxa for these countries is here proposed: U. dioica
subsp. cypria
(endemic to Cyprus), U. dioica subsp. dioica
(syn. Urtica haussknechtii; Iran, Iraq,
Lebanon, Syria, Cyprus and Turkey, Europe, E USA, W, N &
Central Asia), U. dioica subsp. pubescens
(Turkey, also SE Europe east of Italy and Hungary, Ukraine,
Russia), U. dioica subsp. kurdistanica (syn.
U. xiphodon, U. dioica var. xiphodon, U.
dioica var. subincisa; Iran, Iraq, Syria,
Turkey) and U. fragilis (Turkey, Lebanon). The
subspecies of U. dioica show relatively weak
morphological and ecological differentiation, comparable to that
observed in Asian and North American subspecies of this group, but the
recognition of subsp. cypria is recommended on the
basis of weak, but highly consistent morphological characters, such as
the distribution of stinging hairs and its exclusively monoecious
character. U. fragilis can be considered as very
distinct and likely only remotely related.
