40 NEW SYLYA. 



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 17. pinguis or fat Elm of Louisiana must 

 be compared and distinguished if different from 

 both. The V. pumila of Walter 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 Plane- 

 ra aquatica and also Rhamnus 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 

 Planera and cannot clear the subject; but all our 

 botanists distinguish it from U. nemoralis&ltho 1 

 they cannot show distinct specimens of both, if 

 two they are both called Water Elm. Elliot 

 omits the U. nemoralis, but describes twice 

 the Planera 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
