Text-fig. i. Fusion of the two cyst cells and neighbouring cells in the parenchymatous 
issue of a perianth leaf of Anthurium Scherzerianum, third cell row from the epidermis. The two 
large cyst nuclei can be distinguished from one another. Formation of a crystal colony in one of 
the cysts. Obj. 4, ocular 4. 
Text-fig. 2. The section following that of Text-fig. 1, showing the nuclei lying against the 
cell wall. Oil immersion, ocular 2. 
Text-fig. 3. Large cyst cell from the parenchymatous tissue of the perianth leaf of Antkurium 
Scherzerianum, demonstrating the large cyst nucleus after the fusion of a number of nuclei. Another 
nucleus of a neighbouring cell, united, and ready to fuse with the main nucleus. Fusion of the main 
symplast cell with other neighbouring cells. Many crystal colonies formed in different directions. 
Nuclei of the neighbouring cells lying more or less against the cell wall. Some of these nuclei 
becoming homogeneous. Oil immersion, ocular 4. 
and 11 . If the cyst is conspicuously elongated the nucleus is usually situated 
at one end of the cell. After the formation of the first raphid colony, others
