Horrible key nomination

[Jef Veldkamp]

How about

-. Species mihi cognitae
-. Species mihi ignotae

R. Knuth. 1930. Oxalidaceae, in Engler & Prantl, Das Pflanzenreich 95:
p. 57, 71, 77, 85, 132, etc. etc.

There also seems to be a Dutch field guide to birds, that starts off
with

-. Bird sings its own name.
-. Bird does not sing its own name.

This works for birds singing in Dutch only, of course.
