A better option which we used to have for our herbarium and students submssion (that way one can shortlist and include good submissions by students) was to buy card sheets/handmade thick paper from market and get label proforma  printed from a local printer. It comes out much cheaper and customised.

Dear Balkar sir

The supplier at Pune is the sole supplier for herbarium sheets in India. But hope you are aware that one sheet costs aroudn 32 Rs.

One Forestry suppliers also cards are available.

Please follow the link.

http://www.forestry-suppliers.com/icat/Cat63/full.asp?page=421

You can place the order online. I bought something online. It was good experience.

The box of 100 sheets costs, 28 USD which is around 1300 INR. This sounds cheaper than Pune one. Ofcourse there will be delivery charges.

Best wishes.

Pankaj

[Balkar Singh]

Thanks Pankaj Ji for the Information. The Puna Persons are ready to supply @ Rs 10 per sheet as per their quotation i received today. I dont know there may be some quality difference.

Thanks

[Pankaj Kumar]

Good good. They have good quality. I have used their sheets. Dont worry.

Pankaj

Balkar ji, it will be more cheaper if you fallow the suggestion of Singh sir, just purchase a big sheets of Card paper, you can select the quality of paper of your choice, than just get it cut of size 16 1/2 by 11 1/2 inches. i guess it wont go beyond 5 Rs. per sheet

Thanks HS Ji I am searching local market for large size shhets. I found many but there color was very dull slightly greyish like. So trying more options to get some fine color sheets.

[Gurcharan Singh]

Balkar ji the standard size of card sheets is 22 inch by 28 inch, from which you can get three sheets if you are prepared to reduce width from standard 11.5 inchees to 11 inches, or else you can get two 11.5 x 16.6 inches and one 11.5 x 16.5 inch from each card. Alternately you can get two standard size sheets (11.5 x 16.5 inches). In either case you will get extra piece of card from each sheet. We used to get it cut for our reference cards. Printer can do all this job and printing of specific labels for your college on the herbarium sheet.

Yes Sir I think procuring large size card sheets are best option. Pls let me know will there be any problem if color is dull dark or even slightly grey, if to be submitted in any standard national or international herbaria

Thanks

[Gurcharan Singh]

Why the white card sheets are easily available anywhere. Only you should check the thickness of cards before buying.

Sir white sheets available are very smooth may be difficult to handle. Any specific no. size thickness etc you can suggest Sir

[Pankaj Kumar]

Dear Balkar sir
if you are looking for white one then ask for IVORY SHEET. You wont
find anything brighter than that/ You can take one big one and as
Gurcharan sir suggested you can make three sheets out of it.
Pankaj

[Balkar Singh]

Thanks Pankaj Ji.

Colour of sheet matters for using them as herbarium....for standard herbarium...........???????

[Pankaj Kumar]

Dear Balkar sir
You will be surprised by this, but no where in taxonomy or ICBN or IBC
its written that what should be the size of the sheet or color.
Its just a standard that has been maintained so that one size fits
into all the herbaria, as during earlier times, they used to exchange
sheets or send sheets on loan.
Wallich who collected in Indian region along with Nepal, used to
collect tonnes of specimens. He used to make multiple copies of each
specimen he collected. Around 20 for each. Sounds bad, but, later he
distributed his sheets to herbaria across the world which was really
the best thing. Thousands of plants have been named from his
collections.
To me, white is the best color. Ivory sheet remains white for longer
time than the normal high gsm (grams per meter square). Colour sheets
also loose colour which is not good. White has nothing to loose and
gives good contrast....

Thanks for the Detailed information Pankaj Ji. the size of the sheet being used as Herbarium sheet in most of the colleges in Haryana is wrong. even we were also using 11x13.5 size sheets. simply due to the reason that from a standard large size sheet we  may get 4 sheets. From This year onwards we are planning to go via right way. We are trying to get atleast 4-5 thousand sheets and this no. will be enough for me and my students for coming 5 years. So we were little worry about the rules regulations etc for herbarium sheets. 

Now every thing is cleared to me and hope for many other members also.

Thanks to all for providing the information on the topic.

Thanks

[Pankaj Kumar]

Formal size is A3 and is acceptable to all herbaria across the world.
But I would not request you to encourage students to make herbarium
vouchers unless someone is doing PhD. The better way would be to teach
them how to study voucher specimens. At the same time, also teach them
how to make field observations, illustrations of their observations.
You can use the sheet yourself as you are working on Flora of Haryana.

I remember when I took the students of the famous Woodstock school at
Mussorie. I told them to go into the forests and make observations.
Dont bring anything. I know you know ecology (they were on ecology
tour), but bring me something which is your personal observation. No
data matrix and no measurements. JUST OBSERVE AND TELL ME HOW AND WHAT
YOU OBSERVED AND WHAT YOU UNDERSTOOD OF IT.
Interestingly my group did very good. One of the best observation was
made my one of the girls. She said that the area where her plot was
laid, had very good, undisturbed soil and there was no soil pollution
due to usage of chemicals by the farmers or any other sources. I was
surprised, by her observation and asked her curious, "how did you make
that out?". She said, she dig soil with her hands, she could do it
with her hands which itself is a good sign and where ever she did, she
found earthworms!!!
It was such a great observation, which no one teaches in the books!!

Interesting Story Pankaj ji. situation here is not good. exposure to field work is very less particularly in Punjab and Haryana Colleges and even in universities. As per syllabi i asked every student to submit only 15-20 sheets of common wild plants only just to teach them how to press, label and preserve the plant specimens. earlier it was a practice to submit 60-70 sheets whether properly done or not and many unidified. I usually take the student to field tour twice a year atleast one long tour 4-5 days and one short trip for one day. they make their herbarium out of the collection done during these tours generally + some local common plants. I select only good specimen for pasting from the collection of students. As submission of herbarium have a weightage of 5%-10% marks in Practical exam, students have to do it. 

Above all the good thing is that students are taking interest in Botany now. Going for M.Sc and Ph.D in Botany. This is a good sign for us.

[Vijayasankar]

Very good observation indeed, Pankaj.
Coming back to the color & other specifications of herbarium sheet.
While at FRLHT, I had chance to digitize few thousand herbarium specimens from various sources. The ivory or white sheets gave better results with even and clear background (this is important to have undisturbed viewing of specimen details, even when zoomed in), whereas, the even slightly dull or greyish sheets produced bad images. editing was cumbersome and when tried to brighten, the specimen image used to get bleached thus loosing its details.

When buying handmade paper, we should also avoid the ones with too many visible fibers on the surface, they may be in different colors.
So, it is preferred that at least one side of the sheet should be clean white with smooth finish. The size may be between 300 to 500 GSM (needs verification) so that it doesn't bend when woody specimens mounted on them.

Thanks Vijayasankar Ji. Good information, I tried with two types of Handmade Papers, both were rough and dull white to little grey. so rejected them. After this good discussion, My search tomorrow will be only for good white Ivory sheets rather than handmade paper.

thanks  

[Vijayasankar]

Balkar ji,

From your response "...rather than handmade paper" I think I have somewhere conveyed a wrong impression. I didn't mean to avoid handmade sheets, in fact I prefer and suggest handmade sheets, only thing is that we need to select the suitable quality for this purpose. It may be costlier but, after all, herbarium specimens have to 'live' for few hundred years.

Yes Vijayasankar ji

Hand made paper sheets may be of good quality but in our area good quality sheets were not there, so i thought for ivory sheets. Puna hand made paper Institute supply only bulk orders as per their quotations. I think their quality is good.
