Are Festuca and Ochna in the same family?
Festuca Festuca (fescue) is a genus of flowering plants belonging to the grass family, Poaceae (subfamily Pooideae). They are evergreen or herbaceous perennial tufted grasses with a height range of 10 - and a cosmopolitan distribution, occurring on every continent except Antarctica. The genus is closely related to ryegrass ("Lolium"), and recent evidence from phylogenetic studies using DNA sequencing of plant mitochondrial DNA shows that the genus lacks monophyly. As a result, plant taxonomists have moved several species, including the forage grasses tall fescue and meadow fescue, from the genus "Festuca" into the genus "Lolium".
Scolochloa Scolochloa is a genus of grasses in the family Poaceae / Gramineae, now containing a single species, Scolochloa festucacea. Common rivergrass is a common name for the species. "Scolochloa festucacea" grows in Europe, temperate Asia, and North America. Its culms are erect and 100 – in height; its leaf blades are 15 - long and 5 - wide.
