principally them to short notes which fou 
helpful in distinguishing allied species. As already explained, I 
had to carry out f the research w 
dealt with in this preface; consequently the resulting corrections 
have to be embodied in an Appendix instead of in the main body 
of the work. 
The few synonyms cited are those names, or most of them, 
which have been used for the species in Debeaux’s and Kelaart’s 
oras. 
The months of flowering have presented some difficulty. They 
are mostly taken from my own observations, which I find to agree 
much more closely with those given by Perez Lara than with 
Willkomm and Lange’s, which latter, of course, deal with the 
accurate flowering time is not easy to define. For those species 
which I have not myself seen in flower, I have quoted the months 
given by Perez Lara. 
In giving the relative frequency of the species, I may have 
been in error in supposing that those which I have not myself 
he 
localities given on my labels may, I fear, be not very clear to 
sea, “ Bonel’s Farm,” while the west slopes more or less opposite 
San Roque I designate “ Pindalista.” Local names for precise 
localities are most difficult to obtain, and would probably be un- 
intelligible to any one but members of the Calpe Hunt. 
In conclusion, I must offer my best thanks to the several 
friends who have most kindly assisted me with the determination 
of the more difficult species. Dr. O. Stapf has named all my
