A small genus, found iu the mountains of India, the Malay peninsula and islands, and one species in Tasmania,
which also inhabits New Zealand. Tbe M. Pumilio is an extremely variable plant in size of leaf and flower and

A smaller plant than ff. sexdentata, and puberulous, but not uniformly or constantly so : I find no other
difference betu'een these two. Mr. Bentham observes that tills entirely resembles B. Peruviana, except in the long
sterile filaments. G. pubescens is an Australian and Tasmanian plant.
