The handsome winter-flowering Labiate here figured was 
first discovered in Uganda in 1898 by the late Mr. A. 
Whyte, but for its first appearance in cultivation horticulture 
is indebted to Mr. M. T. Dawe, formerly Director of the 
Scientific and Forestry Department, Uganda, who sent seeds 
to Kew in 1905, as well as herbarium specimens collected 
at an elevation of 4000 feet in the districts of Mabira and 
South Buddu. Plants raised from these seeds flowered in 
January 1906, The specimen now figured was sent to 
Kew for identification by Dr. A. R. Wallace, in December 
1911, and originated from seeds received by hin from 
Uganda. : : 
The genus Pycnostachys comprises about thirty-six Tropi-

Africa, with one, P. coerulea, Hook., which is confined to 
Madagascar, and one, P. purpurascens, Briq., known only
