as indicating specific values. LL. Plummerae Coult. & Rose of 
northeastern California and adjacent Nevada resembles L. Nelson- 
tanum in the number of oil-tubes (2-3) in the intervals but other- 
wise it is widely different, notably in characters of foliage. Mr. 
Nelson is an enthusiastic student of the flora of his state and finds 
time apart from his work as principal of the Salem High School to 
do much collecting. It is a pleasure, therefore, to have the oppor- 
tunity to connect his name with this flora in which he takes so 
great an interest. 
“Arctostaphylos drupacea (Parry), comb. nov. A. Pringlet Parry, 
var. ? drupacea Parry, Bull. Calif. Acad. Sci. ii. 495 (1885). Uva-

Mrs. Spencer has secured, as her no. 500, some excellent speci- 
mens of this conspicuous shrub from the region of the type, — near 
Cuyamaca Lake. This Californian species is genuinely distinct 
from A. Pringlei, which is confined to Arizona, by the character of 
the completely consolidated stone. Indeed this is so hard that 1t 
is not breakable by any ordinary means. The fruit of A. Pringle 
however (as shown nicely in recent specimens by Goodding) 1s 
easily separable into four nutlets by pressure between the fingers. 
Since recent collections substantiate the constancy of this striking 
character (pointed out by Parry, 1. c.) and since the ranges of the 
shrubs with coalescent and readily separable nutlets do not meet, 
it seems proper to consider, as Abrams has done, N. A. Fl. xxix. 99 
(1914), the two forms as distinct species. The attempt to use the 
words “ Uva Ursi” as a generic name to replace Arctostaphylos 18 
a procedure which Professor Fernald has shown clearly, Rhodora, 
xvi. 25-26 (1914), to be in accord with neither the International 
Rules nor the “‘ American ”’ Code.

Engler, |. c., showed the necessity of replacing the name Bassia 
Koenig because of the earlier valid Bassia Allioni. He erred, how- 
ever, in taking up the name Illipe, first published by F. v0? 
Mueller, l.¢. The situation is well explained by Cooke in his Flom
