I think this is "Shield fern" !! Can this be Dryopteris marginalis?

Bingo !! I got it on target !! i was waiting for a validation as the sorus are not available in the photos hence I was hesitating to move into the species level but it looked like D marginalis to me.

Dear All, I am attaching the SEM pictures of the sora of two sp. of ferns I got from Wynad(same place as Sri Yazdy's. Is it possible to know the sp.? I am not a Botanist but I have an SEM and just wanted to see the soral features as it caught my attention! Thanks and best regards, Rajaram --- On Thu, 3/6/10, Vijayadas D <dvija...@gmail.com> wrote:

Dear Anantanarayan Ji,
As far as I know the SEM of a sorus (sori) does minutely decipher the structure of a sorus present in the fern but is not enough to determine the genus or species. Available records say that though position , structure and morphology is a major point to validate a fern genus and species but singly is not enough. Hence until and unless the morphology of the plant body in brought into consideration identification is impossible.

Dear All,

As a Palynologist I would like to add some more point in this regard.
The identification of spore and pollen is limited to different level of hierarchy - not always species level.
Some plants can be identified using pollen but as far as ferns are concern I go with Tanay's comments.
This is the major limitation of pollen analysis of past sediments with which am now working.
To overcome this limitation, the plants also need to be classified accordingly.
That is different line of the story.
But am very happy to see SEM pictures of Dr. Anantanarayan.
Regards,

Stephen...

Dear Stephen,
I rightfully comment on the topic many angiosperms as well as  gymnosperm exine morphology and pore structure can determine the species. But When it comenes to Ferns palynologists are really helpless!!

Hello friends,
Which is this Solanum? While raw the fruits appear exactly like the
one identified by Dr. Gurcharan Singh ji as Solanum Capsicoides when
raw but turns yellow when ripe.
Incidentally, though I had agreed with Dr. Gurcharan Singh ji at the
moment, there are no pictures of raw fruits in the pictures sent by
him.

Regards
Yazdy.

Yazdy ji

While trying to identify species of Solanum important things to note are: flower colour and size, fruit colour when young and mature, size of mature berry, and whether surface of fruit (young and mature) is glabrous or hairy. Could you please provide this information.

Dear Yady Ji,
It will be extremely kind of you if you can resend a bit larger photos, it is  easy to notice the minute characters which escape vision in smaller snaps.

Tanay

[Yazdy Palia]

Thank you Sir, Shall do that right away.

Yazdy.

Dear Dr. Gurcharan Singh ji,
The colour of the flowers are white, it may be around 8 mm in
diameter. The fruits are between 15 mm to 20 mm in diameter and are
not hairy. They are very smooth in texture. I have sent you more
pictures by Picasa. They seem to be turning into yellow as they
mature. I am keeping track if they do turn to red at all once it
ripens.
Regards
Yazdy.

Yazdy ji

Tentatively I would call it as S. torvum. The prickles are broad based.

Dear Dr. Gurcharan Singh ji,

Am copying a link to S. Torvum. They look different to me. Am also
sending some pictures from my farm which I thought matches with the
pictures in the wikipedia link.
http://en.wikipedia.org/wiki/Solanum_torvum
Am sending it by Picasa.
Please enlighten me.

Yazdy.

How about Solanum viarum? http://www.shirleydenton.com/plants/plant_www.php?uniq=solan_via

With regards

R. Vijayasankar

[Gurcharan Singh]

Yes Vijayasankar ji and Kunhikanan ji

It could be S. viarum, the only point I find is that berries are supposed to be puberulent which I don't find here.

Dear Yazdy Ji,
This mushroom belongs to the genus Leucocoprinus sp There are about more than 1000 species reported from the  tropics hence hard to determine species from the photos. Sorry for the inconvenience.

Tanay
