PLANTAE MEXICANAE PURPUSIANAE, VIII 



BY 



TOWXSHEND STITH BEANDEGEE 



Interruption of eonnnunication has prevented Dr. Purpus from 

 collecting in Chiapas as he intended. Collecting about Zacuapan was 

 continued and manj^ species not in his previous collections as well as 

 more complete ones of those previously distributed were found. Not 

 having large collections to occupy my time, I have studied out plants 

 of previous collections which were not found in sufficient quantity for 

 distribution. Also are included a few Mexican species collected by 

 myself.
