Notes
:—The name
C. caudata
was published by
Wallich (1829)
without a description or a diagnosis or a reference to a former one (and thus is a nomen nudum), and according to Art. 38.1 of the ICN it was not validly published. The name was validated later by
Wallich (1832)
providing a Latin description (
Chang & Bartholomew 1984
,
Ming & Bartholomew 2007
).
Wallich (1832)
cited in the protologue “Cat. Herbar. Ampl. Procur. Britan. Ind. Orient. n. 978” and stated that
C. caudata
was native to “the mountains bordering on the district of Sillet”. Clark C.B. thought that the locality recorded by Wallich was indicating “Khasia” of
India
(
Anonymous 1913
) and
Sealy (1958)
followed this deduction.
Another frequently recorded locality for the
syntypes
of
C. caudata
is Pundua, which is indicated as “Pundua ~
Bangladesh
” on The Wallich Catalogue website (http://wallich.rbge.info/node/11472). Moreover, an anonymous article on Royal Botanic Garden Edinburgh website (http://stories.rbge.org.uk/archives/5029) has a comment “…Pundua could be modern day Companiganj, or close to it, and not to be confused with Pandua in W Bengal”. However, the current Companiganj in
Bangladesh
is an alluvial plain and its elevation is generally below
50 m
.
Camellia caudata
is usually distributed in the montane evergreen forest between
200 m
and
2200 m
(
Ming 2000
) and it is therefore unlikely to occur in the low alluvial plain in Companiganj. Clark further commented that “…all the collections marked ‘Pundua’ came (certainly to me) from Khasia—no collector at Pundua would attempt collecting southward thence in the swamps…” (
Anonymous 1913
). Therefore, Clark’s deduction of the locality (
Anonymous 1913
) is followed here.
The
lectotype
(specimen on the right side of K001110475) has mature flowers.
Wallich 978
is a set of heterogeneous collections that were collected by different collectors at different times, so the other specimens of
Wallich 978
, excluding the
lectotype
, are not treated as
isolectotypes
but recognized as
syntypes
here (Arts. 8.2, 8.3 and 9.5 of the ICN).
