Studies on the calcium oxalate crystals (Raphides) and idioblast of some selected members of Araceae in Eastern India

The presence or absence of micro-characters in plant system like calcium oxalate crystals, trichromes, hairs etc. has been used for understanding the evolutionary relationships of plant species. The size and appearance of calcium oxalate crystals (COCs) can differ within families, genus, and species and these characteristics might be genetically controlled. We have studied the calcium oxalate crystals in the different...
