OF NORTH AMERICA, 93 
give a Monograph of 32 Species at least, while 
our Authors have only 7 or 8 ; but Bose and 
Loudun have noticed 27 North American Sp. 
while Wild enow and Persoon had only 10, 
However I have but a dozen Sp. in my Herba- 
rium often without flowers or fruits, and I must 
delay this labor ; when I will easily prove that 
this extensive Genus must be divided into 5 
Genera at least, and I am now going to estab- 
lish them. 
729. Fraxxnus Raf. all the Species with 
naked flowers, without calix as in Nudilus, 2 
stamens, and fruit a winged s am are. Leaves 
pinnate, flowers paniculate polygamous . 
730. LEPTALIX Raf. Those differing by 
a smdll calix ddentate &c. Such as Fr . caro - 
liniana , acuminata , pubescens , juglandifolia 
and many other American Sp. but Bose has not 
noticed this important character. 
731. ORNANTHES Raf. 1815. Ornus P. 
Pursh, B. E. &c. Quite different by having 
not only a calix, but also a corolla of 4 petals 
as in Chionanthus . . Ornus being the root of 
many names I changed it to Ornanthes mean- 
ing the flowering Ash : 3 Sp. at least O. rotun- 
difolia, mannifera and Americana. 
732. APLILI A Raf. Flowers and fruits to 
be examined and described, leaves simple. 
Probably more than a subgenus. Two Sp. at 
least. A macrophyla and laciniata, the Fr. 
simplicifolia of late Authors. 
733. SAMARPSES Raf. A minute triden- 
tate calix, stamens 3 ? Fruit a peculiar samarc 
obovate with 3 wings like Halesia, seed trian- 
gular. Leaves pinnate — This must constitute 
a very peculiar genus, the flowers must be bet- 
ter described. 
734. Samarpses trxptera Raf. Fraxinus do
