Rudbeckia triloba, L., a very pretty deep yellow species, much 
more delicate than the 2. Azrta, which has found its way to New 
England. 
Growing in the water of the creeks are masses of Rhytoglossa 
pedunculosa, Nees. (Dianthera Americana, L.), one of the Acanth- 
acee. 
On the gravelly shores Polanisia graveolens, Raf., is a com- 
mon weed. It is usually associated with the “fog fruit’, Lippia 
lanceolata, Michx., alow procumbent member of the Verbenacez, 
bearing compact round heads of bluish-white flowers. 
Climbing in the hedges and associated with Smzlax glauca, 
Walt., and Smilax tamnoides, I, 1 found Exnslenia albida, an 
Asclepiad, with small whitish flowers and heart-shaped leaves, 
which resemble at first glance those of a climbing Polygonum. 
Another common hedge-plant is the bind-weed, Convolvulus 
sepium, R. Br. In the fence corners I found an interesting plant 
which proved to be Seymeria macrophylla, Nutt., the ‘ mullein 
fox-glove”’. 
Most of the trees in this region also occur in New England. 
The woods are composed of oaks, beeches, maples, hickories, 
Negundo aceroides, Liriodendron tulipifera, Fuglans cinerea, L., 
and Juglans nigra, L. Four Leguminaceous trees are indige- 
nous, which occur in New England only as introduced or natur- 
alized species: Robinia pseudacacia, L.; Gymnocladus Canaden- 
sis, the ‘‘ Kentucky coffee tree” ; Gleditschia triacanthos, L., and 
Cercis Canadensis, L. 
Among the oaks the most interesting is Quercus macrocarpa, 
Michx., in which the cup of the acorn is imbricated with pointed 
scales, and is bordered by a mossy margin nearly enclosing the 
acorn. 
The rivers and creeks are lined with tall sycamores, white 
willows and cotton-woods, Populus monilifera, Ait. 
All of the ferns are included in the New England flora; but 
some of the species most common in New England, such as 
Pteris aquilina and Polypodium vulgare, | found to be very rare in 
Ross County. <Aspidium Goldieanum, Hook., Asplenium angus- 
tifolium, Michx., and Camptosorus rhizophyllus, Link., were quite 
common in ravines and on shaded rocky hillsides.
