v.— TWO SPECIES OF ERIODICTYON HERETOFORE INCLUDED 

 UNDER ERIODICTYON TOMENTOSUM. 



The genus Eriodictyon was founded on E. crassifoltum , 

 collected near San Diego, Calif., and described by Ben- 

 tham in the Botany of the Sulphur, page 37. Previous to 

 this, another species had been described and figured by 

 Hooker and Arnott as JVz'g-andz'a Califorfiica} In the Bot- 

 any of the Sulphur, Bentham transferred this to Eriodictyon, 

 giving it the appropriate name E. ghctiiiosuni. It again 

 suffered a change of name when Torrey^ restored its earli- 

 est specific name, calling it E. Californicum. 



Bentham described still another species in the Botany of 

 the Sulphur as E. tomentosum, differing from E. ci'assi- 

 folium in having pedunculate dense cymes, broader leaves, 

 and very numerous, smaller flowers. This Dr. Torrey took 

 as the type under which E. crassifolium should be included, 

 and suppressed the former name, giving, as his reason, the 

 numerous intermediates observed by Dr. Parry and him- 

 self around San Diego and elsewhere. 



Gray accepted Torrey's view with the remark: '■'■ E. cras- 

 sifolium Benth. was doubtless rightly united with this by 

 Dr. Torrey, and this name should have been preferred, but 

 the other is good and of the same date."^ 



Greene described a plant from Monterey County, Calif., 

 collected by Mr. Brandegee in 1885, as true E. tomentosum, 

 and restored the name E. crassifolium to the plant of 

 Southern California.* 



The attention of the writer was attracted to this puzzle 

 by the rediscovery of Mr. Brandegee's plant near Jolon, in 

 the San Antonio Valley, Monterey County, Calif. Truly it 

 seemed that Professor Greene had solved the mystery; but 

 to be certain, specimens of this from Monterey County and 

 of the large flowered E. crassifolium from San Diego were 

 sent to Kew for comparison with the types. The following
