Did you notice how a subject enters and does not seem to leave until everybody is exhausted and perhaps even sick of it? This seems to be one.<<<<
There does not seem to be an exact idea of what we are talking.
As Steve said, are we talking about a Monograph of a country or region or are we talking, as Hermine's comments suggest, about a Monograph of the entire genus?
Sorry to disagree with you Norma, but the object is not getting the job out, but doing it right. A couple of years of delay will be soon forgotten but a poor job will only add to the confusion. We do not need more garbage than we already have. And have we got a lot of it!
As far as I am concerned, all the published material on Flora of XX or Flora of YY (do not want to mention any in particular) that I have seen have severe errors, mainly due to lack of understanding of the genus. In that respect, we collectors, are above them.. but...
Remember one thing,
For instance Sansevieria sp. 'Mason Congo' is the only clone we know. what if tomorrow somebody finds another population slightly different and yet another. This would be the variation of the species and therefore we should not insist that the this species, now still with a cultivar name, should look in such and such way. It can, and does vary.
Cheers,
