Mill from Bhutan, Nepal and Tibet, and Trigonotis clarkei R.R. Mill from Darjeeling) are described. The new combinations Setulocarya diffusa (Brand) R.R. Mill & D.G. Long and Onosma emodi Wall. var. stelligera (I.M. Johnst.) R.R. Mill are made. Tournefortia hookeri C.B. Clarke is lectotypified and the typification of Microula pustulosa (C.B.
