RE: color coding

Ann: Near Kirksville, Frank Oberle showed me what appeared to be a
stabilized hybrid population (or perhaps a particularly successful single
hybrid brood) of L. virginica and L. capitata, both parents also at same
location, a road cut. I'm always on the lookout for possible L. cuneata
hybrids, but am pleased to report I haven't found any suspects yet. James

Ann,

In Dr. Duane Isely's book on legumes (cited below), he mentions
"ubiquitous 
interspecific hybridization" in the genus, and includes a list of the 
common to abundant hybrids found. None of the listed hybrids included 
Lespedeza cuneata as one of the parent species (although they might be 
known to hybridize, just not as frequently). He does state that 
several  hybrids include L. procumbens and L. virginica as parents, 
including the hybrid between the 2 species, which he states is abundant.
In 
fact, the hybrid has been given its own name in the past -- having been 
called Lespedeza brittonii and L. procumbens var. elliptica.

In case you're interested, the book is available through the Museum at
