Selaginella odishana (subg. Stachygynandrum) is described as a new terrestrial species (probably a local endemic) from the Sal tree (Shorea robusta) forest on hill slopes of Daringbadi, Daringbadi Udayagiri forest range, Kandhamal district, Odisha state, Eastern Ghats region of India, and compared to morphologically close taxa (S. reticulata and its allied taxa). The new species is characterised by sub-erect stems, membranous leaf, lateral and axillary leaf, ciliate at the base and serrate distally (towards stem tips) and only serrate (outside face) or serrate margin, lanceolate median leaf with entire-serrate margins, dorsal sporophyll with serrate margins and laminar flap up to ¾ as long as lamina length with ciliate margins, ventral sporophyll ciliate along basal ½ and serrate along distal ½, creamy white megaspores with foveolate surface ornamentation and microspores with smooth surface ornamentation. The conservation status of S. odishana is assessed as Critically Endangered.

卷柏odishana（SUBG。Stachygynandrum）被描述为从萨尔树（新的陆地物种（可能是本地特有）娑罗树）林上Daringbadi，Daringbadi乌德耶吉里的森林范围，坎达马县，奥里萨邦状态下，东高止山脉地区的山坡印度，并与形态上相近的分类单元（S. reticulata及其相关的分类单元）。新物种的特征是亚直茎，膜质叶，侧面叶和腋生叶，在根部具纤毛，向远端锯齿（向茎尖），仅锯齿（外表面）或锯齿状边缘，披针形中叶具全锯齿状边缘背侧孢子囊，具锯齿状边缘和层状皮瓣，最多可达3/4，与具纤毛边缘的叶片长度一样，腹侧孢子虫沿基部½具纤毛，沿远端½具锯齿，具乳白色的大孢子，具凹窝表面装饰和具光滑表面装饰的小孢子。S. odishana的保护状况被评估为极度濒危。
