Let me quote from my article on hosta species ( the number of
hosta species in the very valuable book of Schmid of 43 is
mainly based on the article of Maekawa of 1940 with 38
species instead of on the article of Maekawa of 1969 with 27
species or better on the 22 species of Fujita) is:
The number of Hosta species
From the 14 Japanese species recognized by Fujita (1976[18])
H. alismifolia F. Maekawa (= H. longissima x H. montana;
Sugita, 1994) and H. tardiva are shown here to be hybrids.
Two synonyms mentioned by Fujita (1976[18]), H. rupifraga
and H. rectifolia, are reclassified as species. H. gracillima is
demonstrated here to be a separate species; related to H.
sieboldii, and not a varietas of H. longipes. Further there are
two Chinese species and four Korean species, only casually
mentioned by Fujita (1976[18]). Together with two new Korean
species as mentioned by Chung et al., (1991d[15]), this adds up
to the 23 species accepted here (excluding the newly described
H. albofarinosa, see below). This is similar to the total number
of 22 species for Fujita (14 Japanese + 8 Chinese/Korean
species) or the total number of 22-25 species suggested by
Chung et al., (1991d[15]).
