Dear Peter & al.,

= invalid! (nomen nudum)

>
> = D.*nagamoto

Wrong spelling. The correct name is _D. * nagamotoi_. There is also a
cultivar named _D._ 'Nagamoto'.

> D.spatulata x something = D.*wateri

Wrong spelling. The cultivar is named _D._ 'Watari'. The parentage is
_D.anglica * D. spatulata_.

> D.filiformis ssp.filiformis x filiformis ssp.tracyi =
> D.*'California Sunset' (fertile!)

Not surprising! Many _Drosera_ hybrids are fertile. Only if the
(hybridogenic, allotetraploid) _D. anglica_ is involved, frequently
(not necessarily always) sterile hybrids arise. For more detailed
debates on this topic, please refer to the archives of this
discussion list.

There is also a scientific name for this hybrid (_D. * californica_).
If it is admitted that both parents are varieties of a single
species, the combination _D. filiformis nothovar. californica_
should have been made. This was *not* done by Martin Cheek (who
described the hybrid), however.

Validated as _D. * badgerupii_.

No chance, the hopping routine has already commenced.

Some of them (v.s.) have in fact been published properly (after +/-
significant corrections of the spelling).

Just check out http://www.hpl.hp.com/bot/cp_home. No need to invent
the wheel twice.
