The Plant List
MARK MAZER AND FREDRIKA MAZER (Thu, 30 Dec 2010 14:50:57 PST)

Quoted from the press release by MBG and Kew:

"The Plant List includes 1.25 million scientific plant names, of which 1.04
million are names
of species rank. Of the species names included in The Plant List, about
300,000 (29 percent) are
accepted names for species and about 480,000 (46 percent) are recorded as
synonyms of those
species. The status of the remaining 260,000 names is “unresolved” since
the contributing data sets
do not contain sufficient evidence to decide whether they should be
accepted names or synonyms."
