Bicknell: Species of the Genus Hydastylus 377 



Mendocino Co., Bolander, 1866; Eastwood, 1894; H. E. 

 Brown, 1898. 



Specimens from " California " have also been examined, col-, 

 lected by Dr. Gibbons (1853), Dr. Coulter and E. Hall.

Numerous specimens covering the extended range of this 

 plant of at least seven hundred miles along the California coast 

 show a great amount of variation and give indications apparently 

 little less than conclusive of two closely allied species within the 

 region. 



The type locality of H. Calif ornicus is stated to be " Port 

 Bodega M (A. B. Rendle, 1. a), from whence specimens were taken 

 to England over a century ago. Recent collections by Miss Alice 

 Eastwood, made at Bodega Point, Sonoma County, presumably the 

 type locality, are of the form which has been most frequently col- 

 lected and which shows certain rather suggestive differences from 

 the type specimens of Torrey's 6*. lincatum. As a rule this more 

 northern plant is taller and less discolored from drying with longer 

 and thinner often broader leaves and longer spathes having the 

 outer bract often considerably prolonged, flowers larger, appar- 

 ently more delicately veined and with the segments less broadened 

 toward the apex, and longer anthers. Present material is not con- 

 clusive as to the exact relationship of these two forms, but it 

 would seem that Torrey's specimens may represent a closely allied 

 species of more southern range extending from San Diego to San 

 Francisco, the true H. Calif ornicus perhaps not ranging far south 

 of San Francisco. It may be now impossible to determine from 

 Kellogg's description of his S. flavidum to which of these plants 

 his name implies. It may be noted, however, that in the Herba- 

 rium of the California Academy of Science are two sheets of the 

 more northern plant labelled in pencil u 5. aurcum Kellogg " and 

 another sheet bearing specimens of both plants with penciled 

 memoranda noting their differences. It would appear that these 

 were part of Kellogg' s material and since they bear date some 

 years later than the publication of his 5. flavidum the inference 

 is that he regarded his 5. aurcum as distinct from the latter which 

 would thus be shown to be identical with Torrey's & lincatum.
