Dear Dr Singh
Thank you for providing links to this information. Clearly, it will take a
little time to meaningfullydigest the contents. I had been aware that there
had been strong disagreements about studies andrevisions of Conifers ........
Taxonomists do not always agree and things can get decidedly 'heated'.
We all continue have much to learn about so many genera. I note the section
about "Difficulties with themorphological species concept of Taxus".
Thus not always possible to distinguish between species on the basis of a small
number of photos - no matterhow close-up they are or the level of detail which
is practical with most cameras. Or necessarily make senseof conflicting
information.
Best Wishes,

contorta Griff. ???
A 2010 document1. Which places T. wallichiana and T. baccata in two different
species Groups largely separated on basis of epidermal cells and stomata.
http://www.worldbotanical.com/TAXNA.HTM
2. Treats T. wallichiana (not in W. Himalayas) and T. contorta as distinct
species, a. T. contorta var. contorta (leaves 12 or more times longer than
broad, virgate, spreading by petiole, stomata 5-8(9-11) rows/bands; in
Afghanistan, Pakistan, India, W Nepal) var. mucronata (leaves 5-10 times longer
than broad, sharply bent (reflexed) at petiole, stomata 9-11 rows/bands) in
Nepal, SW Tibet, Bhutan

I do not have any reference books on Korean flora but do possess a copy of
Ohwi's massive 'Flora of Japan' (in English). It (published in 1984) has the
'Japanese Yew' as Taxus cuspidata (syn. T.baccata subsp. cuspidata) with var.
luteobaccata aril yellowish around a greenish seed; and var. nana which is much
cultivated. The species is typically found growing in the mountains. I do not
have any information on the up-to-date nomenclature for this tree but it is not
mentioned as being found in Korea or China (if such a distribution existed it
would have been mentioned in the Flora of Japan).
'Flowers of the Himalaya' had 'Himalayan Yew' as Taxus baccata subsp.
wallichiana, as many will know, giving a distribution of Afghanistan to SW
China, Myanamar & SE Asia & 2100-3400m.
Clearly, the specimen photographed in Seoul is a cultivated variety but is it
the native species for Korea? I do not know what this is?
In the UK we just have Taxus baccata. I think it will be worthwhile to post
some images of the British Yew for comparative purposes. Can anyone tell me
how Taxus wallichiana is separated from Taxus baccata?
