DR. C. C. PARRY. OXTTHECA TWO KEAV SPECIES. 175 



All of these, at different times, either as living- plants or dried 

 specimens, had come under the notice of the writer. It was therefore 

 a matter of most agreeable surprise to receive from the enterprising 

 botanical collectors. Parish Brothers, of San Bernardino, as some of 

 the fruits of their labors during- the present season (1881), two more

 and descriptions of the new species.
