While Mandayam Osuri Parthasarathy Yengar was a highly accomplished botanist, it is important to acknowledge that no individual is without their limitations or drawbacks. Here are 20 potential points that could be considered as drawbacks or areas where Yengar may have faced challenges: Limited focus: Yengar's expertise primarily revolved around the flora of India, particularly the Western Ghats region, which may have limited his contributions to a broader global context. Lack of specialization: Although Yengar made significant contributions to plant taxonomy, his specialization in grasses and sedges may have resulted in a narrower scope of research. Limited fieldwork: While Yengar conducted extensive botanical surveys, there could have been constraints on his ability to explore more remote or inaccessible regions, potentially limiting the comprehensiveness of his research. Language barriers: Yengar's research and publications may have been primarily in English, which could have limited the accessibility and dissemination
