LIST OF PLANTS COLLECTED BY DR. EDWARD PALMER IN 

 LOWER CALIFORNIA AND WESTERN MEXICO IN 1890. 



By Dr. Geo. Vasey and J. N. Rose. 



Dr. Palmer spent some three months in Lower California iifthe early 

 part of this year, and his work has proved very valuable in adding to 

 our knowledge of the flora of this region. His work has been arduous, 

 owing to the drought and heat, and the few accommodations to be had in 

 this wild and sparsely inhabited country ; this, added to his failing health, 

 has made his work doubly trying. 



The following are the places visited, with the date of collection and 

 the numbers of the plants :

In order that the fullest facility for the determination of the plants of 

 the collection here described might be available, Mr. ,T. N. Rose, As- 

 sistant Botanist, spent some time at Cambridge, Mass., in investigating 

 and comparing the plants with those contained in the herbarium of 

 Harvard College. We gladly acknowledge the generous help of various 

 botanists in the determination of difficult species, and especially that of 

 Dr. Sereuo Watson for his aid in studying many of the type plants in 

 the Cambridge herbarium.
