NEW SYLVA, 
acute, some larger oblong acuminate dimidiate, 
all equaly serrate, base very obliqual, often one 
side decurrent the other reduced in size or di* 
midiate. — In Florida and Georgia, shrub 8 to 
12 feet high, leaves pale subcoriaceous, 1 or 2 
inches long, in the narrow leaves the base of 
one side is removed upwards of the petiol and 
that side is much reduced in size whence the 
name : unlike any other sp. very singular and 
curious, fruit not seen. The fine U. alata is 
alone somewhat akin in size of shrub and leaves 
I have found that fine sp. in Kentucky and 
have it also from Tennessee and Arkanzas. 
The Z7. pinguis or fat Elm of Louisiana must 
be compared and distinguished if different from 
both. The V. pumila of W alter is said to be 
the U. alata. 
This fine and useful Genus was thus like 
Celtis in great disorder, Linneus united six 
European sp. in his U. campestris ! and we 
have nearly as many in our White Elms ! It is 
now supposed that U. nemoralis is the P lane- 
ra aquatica and also JRhamnus carpinifolia ! 
being put into 3 Genera! and although Sir James 
Smith doubts the fact, he acknowledges having 
seen only one kind. I have not yet obtained the 
PlaneradLnd cannot clear the subject; but all our 
botanists distinguish it from U. nemoralis, altho’ 
they cannot show distinct specimens of both, if 
two they are both called Water Elm. Elliot 
omits the U. nemoralis , but describes twice 
the Planer a in pentandria and polygamia ! 
I hope my remarks and new sp. will make this 
Genus better known. Abelicea or Planera 
will only be perhaps a subgenus of Ulmus, 
merely distinguished by polygamy and capsule
