FLORA OF AFRICA: RUBIACER. 299 
Eyles (Rhodesia, 1904), Mr. J. Burtt Davy (Transvaal and Swazi- 
land, 1905), and Mr. E. R. Sawer (South Rhodesia, 1905) are 
treated incidentally, as also are those of Pogge (Angola), Zenker 
(Cameroons), and a few others. 
Reference will also be found to three little-known Composite 
plants. One of these is Dicoma radiata, Less., a species inter- 
esting as the sole member of section Rhigiothamnus; this being 
unrepresented at Kew, was not examined by Bentham while 
studying the Composite for the ‘Genera Plantarum.’ The 
two others are old specimens from the Leipzig Garden, forming 
part of the Auerswald Herbarium acquired by the Trustees in 
1871. One may remark, with regard to these three, that the 
number of old types to be seen in this country at the British 
Museum alone is surprisingly large; a fact which, were it kept 
more constantly in mind, would be of advantage to botanists 
commensurably with the handicapping that forgetfulness or 
ignorance of it has entailed in the past.
