Abstract
PROF. MOLISCH gives a general account of the occurrence of laticiferous tissue and mucilage cells in plants, treating his subject specially from the point of view of the latex itself. He finds that the fluid is commonly acid or sometimes neutral in reaction, thus differing in this, respect from protoplasm. He finds a curious form of vesiculated nucleus to be of common occurrence, and describes the protein granules (first detected by H. Karsten), starch, oil, alkaloids and other contents in a number of examples. The protein granules are stated to arise (e.g. in Cecropia) inside special leucoplast-like structures, and elaioplasts are said to occur in the latex of croton. Of inorganic substances, calcium and magnesium are very often met with, but phosphorus, though present in the ash, is not apparently present except in organic compounds.
