One of the training resources that has been produced for use on Soqotra has been a guide to mounting herbarium specimens. The hard copy of this guide was written in Arabic. Presented here are the photographs from the guide with some explanatory text in English, the Arabic version of the text is more detailed. The photographs were taken at RBGE and the text was translated into Arabic by Abdul-Wali Ahmed Al Khulaidi and Mirranda Morris.

The sequence below assumes that you have assembled the materials you need and that you have properly pressed and dried you specimens. green line

2. The label must be stuck down in the bottom right hand corner of the sheet. Stickinf down the label: © Royal Botanic Garden Edinburgh

4. Dilute some PVA glue with water and spread it on a sheet of glass that is slightly larger than the mounting sheets you are using. The consistency to which the glue is mixed will depend on the type of plant material and can only really be judged by experience but will be thinner for softer material and thicker for hard foliage.

Place the plant on the glass, in the glue: © Royal Botanic Garden Edinburgh 5. Place the plant on the glass, in the glue. The idea is to get an even covering of glue on the side of the plant that will be facing the mounting board. The glue can be left on the glass for the entire mounting session - just add more glue or water as required. The glass should be carefully cleaned at the end of the session though or it will be difficult to use next time.

6. Flip the plant over on a clean sheet of news paper and check that no areas have been missed. If they have you can add more glue with a brush. Checking glue coverage: © Royal Botanic Garden Edinburgh

8. Very carefully blot any excess glue off the specimen using greece proof paper or news paper. Blotting off excess glue: © Royal Botanic Garden Edinburgh

Work out where everything will go before you begin any sticking down: © Royal Botanic Garden Edinburgh 9. Build a multi-layer sandwich of specimens, greece proof paper and thick blotting paper. The greece proof paper should be place on top of the specimen to stop it from sticking to the other layers. The blotting paper acts to absorb any extra glue and as a padding layer.

10. Place weights on the top of the sandwich and leave it to dry for atleast 24 hours. Squashing the sandwich: © Royal Botanic Garden Edinburgh

Sewing the thick bits: © Royal Botanic Garden Edinburgh 11. When the specimens have dried any thick twigs and branches should be made extra secure by sewing down with strong thread.

12. Finer twigs and leaves can be made extra secure using small strips of gummed paper. Using gummed paper: © Royal Botanic Garden Edinburgh

The finished specimen: © Royal Botanic Garden Edinburgh 13. The finished product! A good herbarium specimen should last for hundreds of years provided:
  • It has been prepared properly using acid free materials.
  • It is handled with care.
  • It is protected from insect attack.
  • It is protected from water and fungal attack.
