Notes:
—Royle designated Kunawur (northern
India
) as the type locality of his
S. imbricata
. No herbarium specimens were cited in the protologue (
Royle 1835a
). Later when Harry
Smith (1958)
rejected epithet “
imbricata
” (which is later homonym of
S. imbricata
Lam.
), he stated that “the Royle collections are not available, the type cannot be examinated”. He therefore chose collection of
Ludlow & Sheriff 8444
“Kashmir: Mashoo Nullah,
4500 m
, cushion plant on dry hillslopes” as “a substitute for the type”. To our knowledge, no collection of
S. pulvinaria
is present in Herbarium Royleanum in Liverpool, but we were able to find the specimen which may be part of Royle’s original collection in the herbarium of Royal Botanic Gardens Kew (K000732297). However, there is also an illustration cited in the protologue which have to be considered as a part of the original material under Art.
9.4 in
Shenzhen Code (
Turland
et al.
2018
). We therefore chose this illustration as the
lectotype
of
S. pulvinaria
Harry Smith
(≡
S. imbricata
Royle
).
