works like Umasvati's Jambu-dvipasamasa and Ksetravicāra (c. 3rd A.D.) and Brhatksetrasamāsa of Jinabhadragani Ksamaśramana(c. 7th A.D.) also dealt with Geography and some aspects of Jaina cosmology.
Among these works, Ksetravicāra is not available today. Jivasamāsa and Jivavicāra as well as Tandulavaicārika are the works dealing with Jaina Biology. Pujyapada Devanandi (c. 6th A.D.) had composed a treatise named Vaidyaka Sāstra dealing with Ayurvedic medicines, but this work is also not available. Jyotisakarandaka is a Prakirnaka which deals with Jaina Astrology.
In the field of grammar, Jainendra Vyākarana or Indra Vyakarana of Indranandi (6th A.D.), Sakatāyana Vyakarana along with its auto-commentary, Amogha-Vritti of Palyakirti Sakatayana (9th A.D.) and Svayambhu Vyākarana of Tribhuvana Svayambhu (c.8th A.D.) are important works of this category.
The literary evolution of Jainas, particularly in Prakrta, which took place during century 5th B.C- 10th A.D. shows that the Jaina Acāryas were versatile genius. They composed various treatises on different subjects but mainly on philosophical and religious topics.
