occur. Mr. Heller's promised illustrated monograph of 

 the North American species has not, however, yet been 

 completed, and until it appears the systematic classifica- 

 tion of the Lupins must leave much to be desired. The 

 species here figured is a low rather dense bushy denizen 

 of the sand dunes of the Californian littoral from San 

 Diego to a little beyond San Francisco, readily distin- 

 guished, among the species with silvery foliage, by the 

 large and persistently yellow blotch of the standard. 

 The plant which has provided the material for our plate 

 was purchased for Kew in 1913 from Messrs. Bees, 

 Limited, of Liverpool, under the name L. argenteus. It is 

 not, however, the true L. argenteus, Pursh ; nor is it the 

 L. argenteus of Agardh which is a form of L. ornatus, 

 Dough, or the L. argenteus of Watson which is a form of 

 L. laxiflorus, Dough, which are also natives of western 

 North America. Our plant, L. Chamissonis, was first 

 described by Eschscholtz ninety years ago. Its nearest 

 ally is L. aMfrons, Benth., another Californian species 

 which has been confused with it, but which is easily 

 distinguished by the characters indicated by Dr. Stapf. 

 At Kew L. Chamissonis thrives in well-drained light soil 

 if planted against a south wall, beginning to flower in 

 June and continuing to do so freely till the end of 

 November. In the neighbourhood of Los Angeles it is 

 said to flower nearly all the year round. At Kew it 

 matures good seeds and is thus easily propagated.
