My little book on cacti says that examples of bat-pollinated cacti are
"found in the Carnegiea, Pachycereus, Stenocereus and other
arborescent cerei". On the face of it, that's not much help, but
bearing in mind the size of the bats (flying foxes? the size of a
crow?) and the cacti referred to above, they are those huge 10 - 15
metre tall cacti of Arizona and Mexico (Sonoran desert), for example
Carnegiea gigantea (the saguaro), or Pachycereus pringlei (the
cardon). Google for 'bat pollinated cacti'.

Not quite. Cacti are effectively all New World plants (i.e.
all except Rhipsalis), and fruit bats or flying foxes are all
Old World. Some are significantly larger than crows.

Nick Maclaren.

Yes - thanks. Pachycereus pringlei (see 7th pic from top he
http://cactiguide.com/cactus/?genus=...ecies=pringlei)

The total lack of spines threw me completely! For example, see top pic
at same page; that's how I remember P. pringlei (I think I grew it many
years ago!).
