TWO PHILADELPHUS COMBINATIONS. 
ALBERT Hanrorp Moore. 
THE well-known and loved fragrant shrub of every old-fashioned 
garden, the Common Syringa or Mock Orange, is a native of the 
Caucasus and Armenia and possibly of Europe, where it is at least 
thoroughly naturalized in some localities. It is very variable and 
easily passes by imperceptible gradations into a number of wild and 
horticultural varieties, most of which are cultivated in New England. 
One of the best known of these has commonly been called P. satsumz 
Sieb.,! but the original account of the supposed species thus named 
is a hopeless mixture of references to Japanese and American plants 
of quite different groups. "The group including the American element 
is confined to the Western Hemisphere, in fact, the particular subgroup 
intended to the Southern States. It is thus a name which is a “ per- 
manent source of confusion and error." 
P. satsumanus Sieb., according to Miq., and P. coronarius L. var. 
satsumi (Sieb.) Maxim.’ are both based on P. satsumi. Itis true that 
Rehder * attempts to rescue the name P. satsumanus by arguing that 
it is the first one whose description clearly applies to our plant, but 
the first synonym cited under it is P. satsumi Sieb., hence the author's 
purpose was evidently to replace the latter name by the name P. 
satsumanus. This intention to regard both names as equivalent is 
made yet clearer, not only by the obvious derivation of one from the 
other, but by the citation of Siebold as the authority for both. More 
than that, the new form of the name is plainly supposed to be an im- 
provement on a native word by Latinization. 
Whatever P. satsumi is, then, P. satsumanus is also, and, if, as is 
here true, P. satsumi is undeterminable, it logically follows that P. 
satsumanus ought to be discarded with it. Beyond the manifest 
intention of Miquel, we have neither right nor motive to go. The 
horticultural name P. Yokohama or Yokohamae is no better under- 
stood, for it also has been applied variously to our plant and to an ill-
