Crinum, a genus under Amaryllidaceae, is having around 180 species all over the world, and are mainly distributed in the tropical and subtropical region of the world. Taxonomical treatment of Indian species of Crinum was done by William Roxburgh and incorporated in the Flora of India. The perennial geophytes of Crinum spp. generally show morphological diversities in respect of the underground and above-ground parts of them. The different Crinum species have been used in different parts of the world to treat various health problems in the form of tonics, laxatives and expectorants, kidney pains and in urinary troubles etc. and some of such biomolecules are used to treat various health problems in the form of tonics, laxatives and expectorants, kidney pains and in urinary troubles etc. The present study is aimed at characterizing two species of the genus concerning the details of morphological and anatomical features and to contrast them to delimit the species more vividly. Two species under study are Crinum asiaticum and Crinum latifolium morphological characterization of the species has been carried out in terms of the general habits of each species, features of bulb, leaf, inflorescence and floral parts. The anatomical features have dealt with the sectional view of the bulb and lamina. The phenology of these two species has been determined by studying the individuals from different locations at least thrice in a month. The provenances have been noted to differ considerably in their morphological details e.g. gross habit, leaf length, width, margin, floral characters. Plant height, leaf length and margin, the appearance of bulbs, floral morphology along with the anatomical features of leaves and roots has been presented here. Phenological variation has also been noted at the intraspecific level, even when the plants from different localities are grown in the same spot under the same environment, a fact pointing to the inherent difference in the individuals in this regard. Along with the understanding of the range of characters for each species, the study highlights the interspecific diversities for the two species understudy.
