COMMON NAMES : 
   Sandberg bluegrass


TAXONOMY : 
The currently recognized scientific name of Sandberg bluegrass is Poa
secunda Presl. [33,38,70].  Based upon different chromosome numbers,
Soreng [59] recognizes two subspecies of Sandberg bluegrass:  P. secunda
ssp. secunda and P. secunda ssp. juncifolia (Scribn.) R.J. Soreng.  Most
systematists consider the entities listed under the SYNONYMS heading
above to be ecotypes, forms, or cultivars within the Poa secunda complex
[33,40,41,70].  Characteristics used to separate these entities vary
even within a single population and can result from environmental
conditions or a tendency for individual plants to be self-fertile
[33,35,41].

Hickman [33] describes delicate bluegrass as a distinct species, P.
tennerrima Scribn.  Kartesz [38], however, lists it as a synonym for P.
secunda.

Sandberg bluegrass hybridizes with Wheeler bluegrass (P. nervosa) [70]
and Kentucky bluegrass (P. pratensis) [33].
