- The lignin test found most serviceable was the phloroglucin test with hydrochloric acid. Free hand sections of the wood were first treated with a two per cent. solution of phloroglucin in 95 per cent. alcohol. This was immediately drained off and a drop of rather strong HCl added. The result was a beautiful red color assumed by all lignified membranes.
- The best cellulose test was found to be the reaction with chlor-iodide of zinc solution made up as recommended in Steven's Plant Anatomy. If cellulose is present it becomes a bluish-lavender color in this solution. Usually the reaction is slow in appearing and increases to a maximum intensity in a very few minutes. The sulphuric acid-iodine test was also used but found much less satisfactory.
