RE: Adiantum whiteii

 Hi, everyone,

just wanted to put in a plug for the correct name: Adiantum hispidulum
var. whitei

It is not a hybrid, but a form of the very variable apomictic species
Adiantum hispidulum, where the main rachis is bipinnate rather than
pinnate. It is distinguished from all other varieties of hispidulum by
the presence of small stiff hairs among the sporangia on the underside of
the false indusia. Still quite common around the eastern D'Aguilar Ranges
just W of Brisbane.

I've put a photo onto my web page:

  Adiantum hispidulum var Whiteii or these days A. whiteii is an
  species found in 3 places up to about 200km from Brisbane, Qld.

  These areas are Sub-tropical, one an Island the others gullies in a

  Our cold here down to -5C or 23F, it does start to fall over, but
  in the spring.  They like a good amount of sun and good drainage.  I
  use an
  Orchid bark, 30% perlite and Oak Leaves in the mix.

  I find A. whiteii interesting because the stipe, held up to the
  light, you
  can see the minute white hairs on it against the black.
