Scilla and Taxonomic changes

Dear Lauw and Jerry and all,

Jane McGary asked for a source when Julian provided that proposed revision 
data and Julian provided it in a subsequent email to our group, Scilla 
biography. There was some very interesting discussion between the two of 
them (archives from December 19, 2003).…

Julian and I have been communicating privately about Polyxena as I had a 
plant (grown as sp. #2) that bloomed and I wanted confirmation for what I 
thought it might be. I hadn't shared this with the group as I intended to 
do something with the Polyxena wiki page first and haven't found the time 
or decided exactly what. Polyxena has been transferred to Lachenalia by 
Manning, Goldblatt and Fay. Here is the resource:
  J.C. Manning, P. Goldblatt & M.F. Fay, "A revised generic synopsis of 
Hyacinthaceae in sub-Saharan Africa, including new combinations and the new 
tribe Pseudoprospereae", Edinburgh Journal of Botany 60(3): 533-568 (2004).

Julian wrote to me:
  "The article discusses an unpublished DNA study by the same authors, and 
their results suggest a giant taxonomic upheaval for most of the family, 
and they made the necessary numerous new combinations. Apart from the 
sinking of Polyxena into Lachenalia: Drimiopsis and Resnova were sunk into 
Ledebouria; Albuca, Dipcadi, Galtonia, Neopatersonia, and Pseudogaltonia 
were sunk into Ornithogalum; Litanthus, Rhadamanthus, Rhodocodon, 
Schizobasis, Tenicroa, Thuranthos, and Urginea were sunk into Drimia; and 
Whiteheadia sunk into Massonia. At the same time, they recognise the 
splitting of Scilla, but only for the southern African species; no comment 
was made on the Eurasian species. I've also noticed a dozen or so taxonomic 
errors; for example, Dipcadi glaucum was renamed Ornithogalum magnum, which 
is a name already used for an different species of Ornithogalum. All the 
new combinations can be found doing an IPNI search 
making sure that both IK and GCI extended options are selected."

By the way in this new article Scilla natalensis which became Merwilla 
natalensis is now Merwilla plumbea. Another plant we've discussed in this 
group, Eucomis pole-evansii  is now considered a subspecies of E. 
pallidiflora. I don't know if  South African bulb enthusiasts are going 
along with all these changes. I suppose I'll need to write a note on some 
of our wiki pages explaining the proposed changes . Sigh. It is hard to 
keep up with all of this.
