When the plants are dry, many of the firmer varieties may be simply labelled and placed in a drawer or cabinet. The more delicate and perfect specimens should be mounted on stout cartridge-paper, though any ordinary brown paper will answer the purpose if sufficiently stout. The paper may be cut to any convenient size, and if the flower is too tall the stem may be bent backwards and forwards, so that the whole plant may be placed on the paper. The plants may be secured in their places by a little strong solution of gum arabic, paste, or glue. The smaller plants may be gummed at once to the paper, whilst others, possessing a woody fibre, must be fastened down firmly by straps of paper. The best plan to do this successfully is to mark with a pencil the spots where the straps are required, and make a slit in the mounting-paper on each side of the stem, so that the straps may be passed through and be firmly secured by cement on the other side of the paper. This gives a neat appearance to the mounted specimen; at the same time it renders them more secure. It requires but little practice to do this neatly and well. The paper should be kept of an even size, and as far as possible only one kind of plant should be placed on a page.
The naming and labelling of the plants, with their common and scientific names, should never be neglected. Indeed, if the collection is to be of use, either in an educational sense or for future reference, the plants must be classified either according to the Natural or Linnaean system of botany. There is but little difficulty in classifying plants according to the Linnaean system; but if the collector happens to be acquainted with both systems, he may label his plants thus: -
No. 18. Bellis Perennis.
Kenilworth, May 20, 1867.
Class . . .
Division . . .
Order . .
Family . . .
The latter part of the label looks better if printed in blank and gummed on to the left-hand corner of the page.
