S. Cedrosensis, Kellogg, the fruit of which is unknown, from Cedms Island off I^iwer 

 California, is probably S. Emori/i, or possibly S. ambitjua.

2 Among the Colorado specimens of this species. Miss Alice Eastwood mils altenlinn {7.M, iv. 6) 

 to two forms, one large-lenved and with few chiefly axillary flowers, the otlu-r smaller-leaved and with 

 more showy terminal nearly naked spikes. In a similar way Prof. Macoun (Cat. Canad. I'l. ii. 314) 

 distinguishes in S. Brit, (^lumbia a coarse plant witli sharp-lobed leaves from a more nlrnder form 

 with obfuser lobes. In a considerable series of specimens, thei*e and various other variations ap|>rar to 

 be indiscriminate.
