Some sources indicate that Anthoxanthum odoratum and Hierochloe odorata are synonyms. However, other sources list other species of Anthoxanthum are synonymous with H. odorata - but not A. odoratum

Argh! We have entries for both in the PDB, and if they should be combined, I'd like to take care of it. If they are not synonyms, then I'll happily leave well 'nuff alone.

Hoping someone has some good resources that can help sort out this mystery :)

Interesting, MOBOT list Anthoxanthum nitens as the current name for H. odorata and Anthoxanthum odoratum as a separate species.

That's the most up to date info I can find at present

Baa, that's consistent with the USDA's entries for each. And I learned long ago that what seems logical to this layperson (prime example: A. odoratum = H. odorata) has nothing to do with how taxonomists determine synonyms. :o)

A. odoratum and H. odoratum are indeed different plants.
I know, because I've been growing them both :-)

Well, that's good enough for me - they'll stay separate, at least until the taxonomists make a different decision :)

Here's a link listing the differences. http://www.homepage.montana.edu/~mlavin/b434/lab3.htm

Anthoxanthum odoratum- sweet vernal grass sources does NOT spread by rhizomes. http://aggie-turf.tamu.edu/answers4you/grasswee/grasses/sweetver.htm

Whereas Hierochloe odorata - (sweet grass) HAS creeping rhizomes and is slightly smaller.

Hope this helps
