BRICKELLIA ScOPARIA (DC.) Gray, var. subauriculata, var. nov., 
foliis basin versus paulo ampliatis ad 7 mm. latitudine subauriculatis, 
auriculis brevissimis rotundatis, margine revolutis. — Hills of Zacatecas, 
Mexico, 25 October, 1888, Pringle, no. 1766 (type, in Gray Herb.) ; 
also en route from San Luis Potosi to Tampico, December, 1878, to 
February, 1879, Palmer, no. 1077. The hitherto unpublished herba- 
rium name of this variety has been on some plant-labels attributed to 
Dr. Gray, but this seems to have been an error. So far as can be as- 
certained from the material and records at the Gray Herbarium, Dr. 
Gray regarded Palmer’s no. 1077 as typical B. corymbosa, and the 
Pringle plant was not collected until after Dr. Gray’s death. Under 
these circumstances it seems undesirable, as’ it is unnecessary, to em- 
ploy a parenthetical authority in this case.
