260 LEGUMINOSAE 



Fourtli is a sheet bearing a garden specimen (a single flowering branchlet which is leafy 

 below), propagated in London from California seed collected by Douglas. It bears ("in the 

 handwriting of Agardh", says Lindley,— Bot. Keg. sub t. 1979) the label: "Lupinus rivularis 

 prox. N" 1. D. C. 1833. California. Douglas. Garden specimen". Below this label is another label : 

 "L. versicolor B. K<?g. 1979". This sheet, then, is the type of Lupinus versicolor Lindl. (1837), 

 which name, a later homonym, is now replaced by the name Lupinus variicolor Steud. (1841). 

 On the sheet are three other specimens collected in California by Coulter and bearing Coulter's 

 number 393. These are likewise Lupinus variicolor Steud.
