Rout and Deb (Bull. Bot. Surv. India 41: 128-136. 1999) treated this species as Pavetta indica var. tomentosa. Bremekamp (Repert. Spec. Nov. Regni Veg. 37: 113-114. 1934) and Rout and Deb described the corolla tubes as 8-12 mm, but W. C. Ko (in FRPS 71(2): 28. 1999) gave the minimum measurement as 6.2 mm.
