defined phase of P. Gordonianus, an American plant — surely a 
strange confusion. 
Fortunately, there is an available name for our plant, which is a 
Chinese and Japanese variety having more acuminate leaves than the 
type, with conspicuous indurated teeth or serrations, evenly and rather 
distantly disposed, the long-acuminate tip often bent to one side, 
especially in wild specimens. Lange? describes a P. acuminatus. 
Koehne ? cannot distinguish it from the plant currently known as P" 
saisumi. Schneidert also says that it is perhaps identical with 
P. satsumi, as usually interpreted. Authentic material together with 
Lange's figure seem to leave no doubt about this identity. 
Our plant can hereafter be correctly known, therefore, as: PHILA- 
DELPHUS CORONARIUS L. var. acuminatus (Lge.) A. H. Moore, n. 
comb.

P. satsumi and satsumanus of authors. 
P. coronarius L. var. tomentosus (Wall) Hook. f. & Thoms.® is 
another variety of the old polymorphous species, this time, a Hima- 
layan and Tibetan one. A specimen has been examined with the note, 
“Well established on rocky knoll near site of old greenhouse, Arlington, 
Mass." which, while exhibiting some peculiarities, does not seem 
possible to refer elsewhere. "The variety just mentioned is very hairy 
on the lower leaf-surfaces. 
There are likewise several closely related species approaching the 
type or one of the varieties, which make the group a puzzling one. 
In our Southern States one of the finest of the sweet-scented species 
is native, namely, P. pubescens Lois.6 This species usually has longer 
racemes and handsomer foliage than P. coronarius, though the frag- 
rance is not quite so strong or lasting. There is only one ‘Mock 
Orange.’
