Stipa danubialis Dihoru et Roman
|
A very peculiar species of Stipa from a series of species which all seem to be relict narrow endemics (see below). Their main character is the pubescent column (all the other species with plumose awns have a glabrous column). The taxon is a narrow endemic of Iron Gates area.Below there is an extract from the article of Pardo et Esteban (2011) p. 645-655. which can be seen in extenso here. This places our narrow endemic species in a special series within the genus Stipa along other six narrow endemics from other regions which have also a pubescent column. Stipa ser.
