PREFACE, 
Tus work is designed to be a running Supplement and Illustra- | 
tion of the “ Frora Carensis,” or General Description of the 
Plants of South Africa, now in preparation by Professor Harvey 
and Dr. Sonder. 
It will consist of figures and descriptions of new plants which 
may be received during the progress of the larger descriptive 
work, and also of any South African plant which the Author 
may think worthy of a figure. The great extent of the Cape 
Flora precludes the possibility of figuring all its species; and 
even a complete illustration of the Genera would require 1500 to 
2000 plates. Hence the necessity of limiting ourselves to plates 
of new, unfigured, or little known plants, or to such as, by their 
structure, use, or beauty, specially recommend themselves to 
notice. ‘— 
Eyery volume of the “‘ Tursaurvs” will contain 100 plates 
and descriptions, and be complete in itself. It will be published 
in quarterly parts, each of 25 plates; and though the Author 
does not bind himself to publish more than one volume; yet, if 
supported, this precursor may be followed by five or six, or even 
‘more, similar volumes. ‘The impression is limited to 250 copies, 
of which 150 are reserved for colonial sale. The expenses of pub- 
lication are divided between the Author, who contributes the 
plates, and the University, which gives the letter-press; and the 
profits of sale, if any, will be applied to enriching the Herbarium, 
which is kept up by the University for the free use of the bota- 
nical public. i oe: 
The figures, with rare exceptions, will be drawn by the Author 
from specimens preserved in the Dusuin Universivy Hersa- 
k1uM, which will be throughout quoted as “ Herb. T. C. D.”
