s.n. (K!)
This species was treated as
Clarkeasia parviflora
(T. Anderson) J.R.I. Wood
by
Wood (1994: 189)
but based on subsequent molecular and morphological studies (Carine &
Scotland
2002:
Moylan et al. 2004
), it is clear that the genus
Clarkeasia
should be included within
Strobilanthes
, where the oldest available name is
S. violifolia
.
Strobilanthes violifolia
is, in fact, sister to
Aechmanthera gossypina
(Wallich) Nees
(
Moylan et al. 2004: 732
), a species already transferred to
Strobilanthes
as
S. tomentosa
(Nees) J.R.I. Wood
(
Wood &
Scotland
2009: 16
). The sheet annotated by Anderson at CAL is selected here as the
lectotype
as we cannot locate any other specimen at K or elsewhere that can be considered for lectotypification.
Var.
albescens
of
Clarkeasia parviflora
is included in the synonomy as it has no clear geographical patterning and is probably analagous to the lanate forms of
Strobilanthes tomentosa
(Nees) J.R.I. Wood
, treated as a synonym of that species by
Wood &
Scotland
(2009: 21)
, who postulate that that the white-felt indumentum represents a developmental stage. Given that
Strobilanthes violifolia
and
A. tomentosa
are sister species (
Moylan et al. 2004
) and that at least one intermediate is known (Grey-Wilson & Phillips (K) from
Nepal
), similar developmental traits in both species might not be unexpected.
Strobilanthes violifolia
is quite widely distributed being recorded from
Nepal, Bhutan
,
India
(
Himachal Pradesh, Sikkim, West Bengal, Meghalaya and Manipur
) and
Thailand
(
Nan and Kanchanaburi
). Its absence from
Myanmar
is curious and it might be expected to be found there
.
