A very rare species in Romania, with a few
small populations in the forest-steppe of Moldavia and Transylvania.
These localities are the western most for the range of the species,
which is vast, covering the whole Eurasian steppes and
forest-steppes including the subtropical ones from southern
Asia (see here
the page of the species in Flora of China, here
in Flora of Pakistan, here
for Nepal and here for
Afghanistan - hence the species is not a Pontic element as
credited by many Romanian authors but a continental Eurasian one).
The range expands in the subtropical forest-steppes of southern Asia
and even in the dry grasslands of southern Australia (where it is
considered as native and vulnerable, under the name Polygala
japonica Houtt. (a taxon sometimes considered a variety of
Polygala sibirica L. ) - see here
and here).
In China, India and Australia as well it is a highly valuable
medicinal plant, under the name of Yuan Zhi.
In 1997 the species was recorded also in
Bulgaria (see here and
here).
Beautiful images with this species from China
and Russia can be seen here
and here.
In the forest-steppe of Moldavia it is known
from Valea lui David (Iasi county) and Bacani (Vaslui county). In
Transylvania it was known in the XIXth century from Cenade (Alba
county) where it got extinct. In the 70s of the XXth century it was
reported again from Boarta (Valea Marului) and Mihaileni in Sibiu
county from where seemingly it disappeared again. The images
provided to us in 2012 by dr. Dragulescu Constantin from around
Boarta, Seica Mare and Petis, Sibiu county as representing
transitional forms between this species and Polygala vulgaris
are certainly only individuals of this latter species. The same
remark is valid for the individuals mentioned by dr. Klaus
Gross near Cris, Mures county.
In June 2012 we found a new small population
(yet incompletely surveyed north of Ernea, Sibiu county which is
documented in the images below.
