A letter I got today confirmed my suspicions that the plant
on the back cover of the most recent CPN is _U._gibba_ and *not*
_D._villosa_ --the author of the letter was Peter Taylor, who is
fairly knowledgable on this genus. :)
Last night I was preparing some _P._vulgaris_ `Ontario' for the
refridgerator and saw, for the first time, gemmae from this genus.
They are tiny!
