Abstract

Thottea sasidharaniana (Aristolochiaceae), a new species from the southern part of the Western Ghats, India is described and illustrated. The new species is phenotypically close to the Indian species T. dinghoui. However, it differs from the latter in its ovate and glossy leaves, larger bracts, uniseriate stamens, 6 anthers, short and pubescent filaments and fewer seeds per fruits. It resembles T. tomentosa in having 6 distinct anthers, but the non-urceolate flowers and the inflorescence architecture distinguish T. sasidharaniana from T. tomentosa. The latter species is distributed from Bangladesh, India (i.e. Andaman and Nicobar Islands, Assam, Manipur), Thailand, Malaysia, Java, Sumatra to the Philippines.
