My understanding was that Hodkinson and Lendemer (2011) took care of this

and assigned X.hypofusca as a proper name:

Confused again (what’s new!?)

Jim Bennett crossed my X.hypofusca and wrote X.tasmanica on the specimen. I have X.tasmanica crossed in my lists based on something that I read prior, and replaced with X.hypofusca. However, looking in CNALH, there is not much about X.hypofusca, but X.tasmanica has a good description (from Sonoran flora I guess). What’s up with this – did it change again in the last couple of years, or did I goof up somewhere?

Black below.

Spotted knapweed is shown in the second photo to gauge the size (20cm or so).

Non-isidiate, lower surface black, medulla K+ blood red – mostly, although some areas are orangish. That concerns me, because another identifying trait – lobe size – that’s supposed to help separate this species from X.angustiphylla is unreliable, with lobes ranging widely in size depending on where they are on the thallus.
