Re: color coding

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.

Information from:
Isely, Duane. 1998. Native and Naturalized Leguminosae (Fabaceae) of the United States (exclusive of Alaska and Hawaii). Monte L. Bean Life Science Museum, Brigham Young University, Provo, UT 84602.

In case you're interested, the book is available through the Museum at the address given. Hope this helps --

Collecting seed on a roadside glade this fall, I realized I don't know if
sericea lespedeza crosses with our native lespedezas.  Two native, L.
virginica and L. procumbens and the sericea, L. cuneata were present.
Anyone have knowledge of potential hybridization?  Steyermark mentions in
the Flora of Missouri some native lespedezas apparently hybridize.
