This plant that I asked about is apparently not a Salvia at all, but
the Chaste Tree, Vitex (Verbenaceae). Thanks to Dr.Bill Cole of Texas
who emailed me shortly after I posted the message quoted below.
This points out one of the mistakes that can be made when trying
to ID a plant - "jumping to conclusions" too soon. After all the times
I told students not to do this, I did it myself! Assuming that an aromatic
plant with opposite leaves and a bilabiate corolla was a Mint! That
left me mired in the Lamiaceae keys for more than a week.
Because Verbenaceae is a family with very few representatives in
the California flora, I had totally forgotten about its affinities
to the Mints, and the fact that it could have very aromatic members!
Following up yesterday, I was able to see that Vitex fit my specimen
just about perfectly.
I love this group! I should have posted the question a week ago
and saved myself the angst. Thanks! - NH
