The Indigoferas of China. 
BY 
W. G. CRAIB, M.A., 
Assistant for India, Royal Botanic Gardens, Kew. 
SOME time ago the writer, at Professor Balfour’s request, under- 
took the revision of the Chinese Leguminosae—with the excep- 
tion of a few genera which were being, or had already been, 
revised by botanists making a special study of those genera— 
preserved in the herbarium attached to the Royal Botanic 
Garden, Edinburgh. Shortly afterwards, Professor C. 
Sargent offered to place at’ the writer’s disposal most of the 
Leguminosae collected by Mr. E.-H. Wilson during his expeditions 
to China under the auspices of the Arnold Arboretum. Advan- 
tage was taken of the bringing of these large collections to Kew 
to compare them with the copious material in that herbarium, 
and to revise the genera where necessary. 
The first genus to be examined was J ndigofera, and here so 
much unnamed material had accumulated that it was deemed 
advisable to go rather fully into the genus, and the results of the 
examination are given below in a preliminary enumeration, 
accompanied by an artificial key to the species enumerated. 
In the enumeration there are incorporated, besides the material 
mentioned above, the specimens preserved in the Natural History 
Museum, S. Kensington, permission to examine which was kindly 
granted by the keeper, Dr. Rendle. 
In conclusion, the writer begs to acknowledge his indebted- 
ness to Professor Sargent for allowing the descriptions of the 
new species collected by Wilson to be incorporated in the 
present paper instead of (as was originally intended) in the next 
part of the Plantae Wilsonianae. By this arrangement the great 
<sgaiaea is secured of having all the descriptions in one place.
