The present investigation has been carried out in order to define the histo-anatomical features of vegetative organs belonging
to five Fumaria species and to provide a microscopical characterization of the powder obtained from the aerial dried parts of
these species. The microscopic characterization of the powder histological elements was made by comparing them with data
existing for the officinal species, Fumaria officinalis L. The following species were analysed: Fumaria rostellata Knaff.,
Fumaria parviflora Lam., Fumaria vaillantii Loisel., Fumaria schleicheri Soy.Will. and Fumaria jankae Hausskn.
The revealed differences regard mainly histo-anatomical structures of the stems. In this view, the aim of the present study
was to identify the differences between the five Fumaria species and to determine if the number and positioning of the
collateral vascular bundles in the angles of the pentagonal-shaped stem are different for each species. Data obtained in the
current study can be useful to develop further scientific investigation, and represent a strong evidence to avoid possible
confusions between the species of Fumaria genus, at the same time being a landmark, the first of this type in our country, for
these five species.
