[MAIPC] Corydalis incisa: be on the lookout

[Ruth Douglas]

Yes, thanks Margaret. And two very good taxonomists  in Virginia, Gary
Fleming and Tom Wieboldt have looked at it and would surely have said so if
they didn't think it was C. incisa.

 

If anyone wants pictures of the plants I found on Monday, send me an email
at my cvilleruth address and I will send you 2 pictures of what I found.

Purple or white flower color looks like a pretty clear identifier -
according to Flora of Virginia, we only have one native Corydalis: the much
smaller yellow-flowered C. flavula. C. sempervirens has pink flowers ( & has
been renamed Capnoides sempervirens). Then there is Fumaria officinalis with
round seedpods - and it isn't native.

Ruth,

Just to be sure.. How do you know that this is incisa? There are a lot of
native Corydalis as I'm sure you know... Some look like this. I just want to
be sure the identification is correct.

Thank you!

Last year around the end of April I went looking for possible Corydalis
incisa along Red Bud Creek, near my home in Albemarle Co. VA. I found
probably 40 plants in bloom and starting to go to seed. I pulled up all
those I saw and flagged the area. This year I went back on April 3 and found
about 15 plants in bloom nearby, but not yet going to seed, and pulled them
all and again flagged the area.
 
In the last several days I have heard of two more infestations in Virginia,
one more in Albemarle Co. and one in Madison Co., both in extensive private
native plant gardens. I don't know if the plant hitchhiked in with another
plant purchased from a supplier or whether the owner planted them without
realizing that they could be very invasive; I will investigate that.
 
I don't think I can attach a picture, but here is a link to a photo
