A reply from Dr. Chris:
"I just returned from working on my extensive collections in Helsinki
Botanical Museum.
The photos sent of this species are very clear even though they are rather
small plants - the wall habitat is quite typical.
This is the species previously known as Parahemionitis cordata. In common
with more than a few fern species, it has an involved nomenclature as it
was known before that as "Hemionitis arifolia", but concerning the genus,
Dr. Mickel and Prof. Tryon found that it is not the same genus as the
American genus, Hemionitis, and having read that and leaping in (with no
less than 3 rapid papers before he managed to actually validate it!),
Panigrahi took it upon himself to set up a new genus for it,
Parahemionitis, and called it Parahemionitis arifolia prior to any
finalisation of it by Mickel or Tryon.
However concerning the specific name, the late great Dr. C.V. Morton
found that Nicholas Burman's only actual specimen of his basionym,
"Asplenium arifolium", so labelled in G and complying sufficiently well
with his description, was a juvenile baby Acrostichum aureum, with an ovate
and slightly cordate leaf, as identified correctly before him by Alston.
Thus like most early and less precise authors, Burman's concept was mixed
and involved some misidentification - a very common situation affecting
anyone from Linnaeus himself onwards! Although Morton expressed the
possibility of a little doubt, which has no actual effect, he then clearly
and formally cited the Type, and lectotypified A. arifolium on that
specimen, which is thus the identity of that name and under the ICN should
not be superceded and changed again. Thus the epithet "arifolium" cannot
be used for this species. The next available basionym is Roxburgh's (ex
Hook. & Grev.) Hemionitis cordata, which is the basionym for the current
and correct name of the species, Mickelopteris cordata (Roxb. ex Hook. &
Grev.) Fraser-Jenk.
A recent paper attempting to relectotypify Asplenium arifolium in the
misapplied sense it was being used in in India, having read about the
situation and details from my previous book (but misleadingly not citing
that source!) was both unnecessary and misunderstood the situation and has
no effect on the final nomenclature.
The species itself is also complex as there are different cytotypes,
both apomictic and diploid sexual, with different ranges and it has been
investigated in detail in an interesting paper and programme by Taiwanese
botanists. There is a diploid sexual taxon in Sri Lanka.
If plants manage to become more mature and larger in a good season,
they are interesting in producing small vegetative bulbils and leaves of
new plants in the cleft where the stipe joins the lamina. This is
frequently seen in South India, or anywhere where the local climate is
suitable for good growth. Old leaves can then grow small colonies of
vegetative new plantlets in this way as they touch the substrate. The
species is already known from West Bengal, the type being from Bengal.
Like the enquirer I have myself also not seen it in Kolkata, but I
think I may have seen old specimens from there - I don't quite remember now.
Best wishes,
Chris Fraser-Jenkins, Kathmandu."
Thanks a lot, Chris ji.
