Abstract
Strobilanthes callosus Nees is endemic to India and flowers once in its life cycle. In Peninsular India, it is reported in bloom after 7 years. During a botanical tour to Anshi National Park, Mookambika Wildlife Sanctuary and Kudremukh National Park, the authors reported this species in bloom in Pune, Satara, Kolhapur (Maharashtra), Belgaum, Dharwad, Koppal, Udupi, Mangalore, Shimoga, Davanagere, Uttara Kannada and Haveri Districts (Karnataka). From Koppal, Udupi, Mangalore, Davanagere and Haveri Districts of Karnataka, this species hitherto not reported. A complete citation, short description and notes are given. This documentation is essential to ascertain periodicity in blooming for various species of Strobilanthes.
