Osmundastrum claytonianum (L.) Tagawa., J. Jap. Bot. 17(12): 697-698 697 1941. (syn: Osmunda claytoniana L.; Plenasium claytonianum (L.) C. Presl; Struthiopteris claytoniana (L.) Bernh.);
Wild Fern captured on 13/8/10 during the trek from Ghangaria (around 11,000 ft.) to Hemkunt Sahib (around 14000 ft.).
Yes it is O. claytoniana with pinnate vegetative fronds with pinnatifid pinnae. O. regalis has bipinnate fronds with subentire to denticulate pinnules.
I received this picture and accompanying write up today from UBC…. the URL is
MY question is about the names: Osmunda claytoniana the current name and Osmunda claytoniites for the fossil… they claim is almost identical…
My question is clayton- iana versus clayton- iites
what does -iana depict that is different from -iites ????/
these spellings appear in one of the paragraphs in the above URL… I am copy pasting ithe paragraph below within quotation marks….
“Osmunda claytoniana has the “oldest known fossil record of any living fern”, and can be traced back to the Triassic period<http://www.ucmp.berkeley.edu/mesozoic/triassic/triassic.html>.
This species can also be considered a living fossil<http://en.wikipedia.org/wiki/Osmunda_claytoniana>,
because it appears almost identical to a fossil fern species from 200 million years ago, Osmunda claytoniites. It has gained the common name interrupted fern because of the appearance of its fronds, on which the brown
fertile pinnae “interrupt” the green sterile pinnae<http://www.ct-botanical-society.org/ferns/osmundaclay.html>.” end quote
claytoniana [ klay-ton-ee-AH-na ] named for John Clayton, 18th century Virginia plant specimen collector; described as the greatest American botanist of his day
claytonia [ klay-TOH-nee-eye ] named for John Clayton, 18th century Virginia plant specimen collector; described as the greatest American botanist of his day
claytoniites [ klay-toh-nee-EYE-tees ] my guess: refers to being like claytonii, in this context perhaps, being like claytoniana … wait for comments.
Above pronunciation and meanings sought from Dave’s Botanary<http://davesgarden.com/guides/botanary/>.
Know nothing beyond this.
claytoniana means “like Clayton”. Its an adjective of “Clayton”.
claytonii means “of Clayton”. Clayton is used as a Noun, saying the specimen that belonged to Clayton or collected by Clayton.
claytoniites means “looking like claytoniana” or if we take the whole plant name then it means looking specifically like Osmunda claytoniana. Please attached my pic of Osmunda claytoniana from Himachal Pradesh, just before Rohtang Pass.
To add to what … has written claytoniana, a specific epithet in adjective form (since Osmunda generic name is in feminine form), may take form of claytonianum (if attached to a neuter genus) and claytonianus (if attached to masculine genus)
claytonii, a noun in possessive form, will remain unchanged from genus to genus; -ii for all names ending in consonant, -i for names ending in vowel (roylei for Royle), -e for those ending in a- (senguptae for Sengupta), etc
cyatoniites here signifies two things, one it is like O. claytoniana, and second more important it is a name for a fossil. ending -ites is commonly used for fossil taxa.
I was going through … remark and I just wanted to add some thing more.
Gender is a big issue in ICBN.
According to ICBN, II:VII:2, Article 62.1. A generic name retains the gender assigned by botanical tradition, irrespective of classical usage or the author’s original usage. A generic name without a botanical tradition retains the gender assigned by its author (but see Art. 62.4).
For example, Punica granatum. Ideally Punica is of feminine gender, “ending with ‘a’, hence the species name should have been ‘granata’, but this name has been conserved because of its long usage. But the question is, according to article 62.1 name should have retained the gender assigned by botanical tradition irrespective of the usage by author. Hence this goes against ICBN.
Second example could be Quercus oblongata. Though the gender of genus according to name is masculine, but classically they were treated as feminine hence, the species name is feminine.
For the understanding of a common person, if you go through ICBN ARTICLE 62.1: IF YOU NAME YOUR SON “RAMA” AND YOU DONT SAY IF IT WAS MALE OR FEMALE THEN ACCORDING TO THE ARTICLE IT WILL BE CONSIDERED FEMALE FOLLOWING BOTANICAL TRADITION. VERY INTERESTINGLY LORD RAM FROM RAMAYAN IS OFTEN REFEREED AS RAMA AND RAVAN AS RAVANA IN ENGLISH!!
IN HINDI TRAIN AS RAILGADI IS FEMALE, ENGINE IS FEMALE, BUT THE BOGGIES ARE MALE !!
Quercus (Q. dilatata, Q. acuminata), Prunus (P. persica, P. armeniaca), Pinus (Pinus alba, P. africana) are all feminine because they are trees, and in classical Latin, tree is treated as feminine. Perhaps all trees are feminine, irrespective of the ending of the generic name.
What about Oroxylum indicum, Phoenix sylvestris, Pterospermum acerifolium, Dimocarpus longan!! 🙂
Its very tricky as both options are there. A tree should be female according to botanical latin, but at the same time it can be male if the name doesnt follow the botanical tradition and author calls it male!!
Yes there are some exception, but majority (say in Manual of Trees by A Rehder) follow the feminity rule.
Differently, in Hindi, trees are male!!
Most Indian Words (in different languages) the ending of the word (except for a few like kursi, chapati, khirki) don’t give indication of its gender, and that is why in most cases what we call as ‘mera’ in Hindi (or say North)
would be called as ‘meri’ by a friend from South or East. This is what I had been often telling my students. In Latin (and for that matter even Russian)
ending of the word generally tells us its gender, not in most Indian languages.
I think this also depends on the word that comes after.
Fwd: Osmunda claytonia L. ‘The Interrupted Fern’ on Khelanmarg : 3 posts by 2 authors. Attachments (6)
I was surprised to find no postings of this fern from Kashmir but note O.regalis was posted from the same location.
Would our fern expert kindly pass his eye over the attached images (my apologies for not taking any shots of the undersides of the fronds)? I was not feeling at all well that day (and had already developed, at that time an undiagnosed condition – I just thought I was “slowing down due to getting older).
According to Stewart, Osmunda claytonia known as ‘The Interrupted Fern’ is gregarious on forest banks and grassy hillsides usually above 2400m. Recorded from Hazara, Poonch whilst abundant in Kashmir.
He considered that Osmunda regalis had only been recorded from Hazara with no records from Kashmir.
Rather odd, I have a copy of ‘Plants of Gulmarg (Kashmir)’ by A Naqshi, G Singh & K Koul (1984) which lists Osmunda claytonia as common among bushes on Khillenmarg which appears to support Stewart.
Could I suggest some more authoritative and up-to-date Indian fern-literature, to avoid these long-solved problems of half a Century ago?
Thanks, … Yeah, that will be really nice of you.
Yes, …, this would be helpful for those taking an interest in ferns.
As I said in my recent post, a pity that more authoritative and up-to-date literature does not exist for FLOWERING plants of NW Himalaya.
