According to latest records, the genus Astragalus L. in Turkey, represent with about 450 taxa.
Among them, 151 taxa are thorny members whereas 299 taxa are non-thorny and the
endemism rate for genus is about 45%. In this study, the threat categories of members of
sections of Hypoglottidei and Dissitiflori are given. In Turkey, the section Hypoglottidei has
16 taxa, three taxa are in category of CR and two taxa are in category of EN. In addition, the
section Dissitiflori has 11 taxa in Turkey, 4 taxa are in CR category and one taxon in EN
category. In this study, localities of each species, habitat information and reasons for threat
categories are discussed.
Keywords: Astragalus, Hypoglottidei, Dissitiflori, Turkey.

In the present study, the circumstance of Parnassia vanensis in Flora of Turkey and the
East Eagean Islands was tried to be explained . The specimens were collected from Norduz
plateau during field studies. The taxon was catagorized as imperfectly known in flora of
Turkey.
Parnassiaceae presented with one genus and one species in Flora of Turkey. Aznavur
collected the specimen in 1918 from Erek mountain which is close to our investigation area
and published as Parnassia vanensis Azn.; The P. vanensis differs from P. palustiris L. in the
basis of angled staminod, ovat petals rather than oblong or oblong-spathulat. Later, Al-Rawi
reported to collect the species in 1964 from northern Iraq which is also close to our
investigation area. The author made the description of genus in Flora of Turkey proposed that
the specimen could be a synonium of P. palustris because he had not seen the specimens
mentioned.
This study presents the existence, detailed descriptions, drawings, colour photograps taken
from field and ecological specifications of Parnassia vanensis Azn.
