114 Coville Botanical Explorations of Thomas NuttalL 



LIST OF PRINCIPAL NEW SPECIES BASED ON NUTTALL'S 

 CALIFORNIAN COLLECTIONS. 



Collected at Monterey. 



BRASSK'ACEAE. 



Dentaria integrifolia Nutt. Plains of Monterey. 



Erysimum grandiflorum Nutt. = Chdrantkus capitatus Dougl. On the 

 sand hills of Point Pinos, near Monterey. March. 



Lepidum californicum Nutt. = Lepidium menziesii DC. It may be well 

 to note that although L. californicum is referred by recent authors to L. 

 menziesii, the latter is considered by Dr. Robinson in the Synoptical Flora 

 a plant of the Northwest Coast, a district far removed phytogeographic- 

 ally from Monterey. This suggests the need of further critical examina 

 tion of the Monterey plant.
