128 LEAFLETS. 
No shrubs that have been referred to Rhus are more foreign 
to that type than those that have been called the Sweet Sumach. 
They have a watery juice and their twigs and foliage are aro- 
matic and wholly innocuous to the touch. Their flowers appear 
before the leaves, and from ament-like spiciform clusters imbri- 
cate like those of a birch, alder or hazel, and like those they are 
formed in late summer to remain dormant until spring. Their 
floral structure is as unlike that of Rhus or of Toxicodendron. 
The first species to be seen in Europe was published by Philip 
Miller, under whose nurture the bush had grown in the Chelsea 
garden, as a species of Toxicodendron. The same was after- 
wards named as Betula by Thunberg. Rafinesque in 1808 made 
it the type of a new genus to be called Zurpinia; this at just 
about the time when several other botanists were dedicating 
each a genus Turpinia. Rafinesque’s genus of that name proved 
to be other than the first; and, before he found this out, and, 
before he had published the genus with good character and the 
well formed and euphonions name Lodadium, Desvaux had got 
into print the wretched barbarism, Schma/tzia, supposed to be 
dedicated to Rafinesque, who sometimes wrote his name 
Rafinesque-Schmaltz. That this name was not only ill sound- 
ing and barbaric, but also on the whole untrue to Rafinesque, 
and published obscurely, without a character, are three circum- 
stances which must have availed with De Candolle, Asa Gray, 
and others for the recognition of Lodadium rather than Schmalt- 
zia as the name to be perpetuated. 
To the specific characters in ScHMALTzIA no attention seems 
to have been given since Nuttall’s time, and our herbaria are 
replete with specific types not hitherto characterized. A consid- 
erable number of such are herein briefly defined, while others 
remain to await further study. 
S. CRENATA. Toxicodendron crenatum, Mill. Dict. n. 5. 
Rhus suaveoleus, Ait. Kew. i. 368. All stems and twigs, even 
the growing ones perfectly glabrous, smooth, reddish brown: 
foliage large, thin, vivid green and almost shining above, paler 
beneath and to the unaided eye glabrous throughout, a lens dis- 
closing minute hair-tufts in axils of veins beneath, as also at 
some of the marginal sinuses, and a few scattered hairs along the
