Cycloloma platypiiyllum, Moquin,— While folleetiiig fisli with Prof. D. J. 

 Joi-daii in F:ill deck, a tributary of Wliite Kiver, in October, we found Ci/cloloma 

 jilati/phijlhim, Moq. well ej^tablislied in the low sandy banks. This seems to be its 

 most easterly station yet reported. In the same month we foun.d in our door yard 

 Nastvrthim sessiliflorum, Nutt. It continued in blossom until the frosts had killed 

 many plants usually ranked hardier. Dactyloctmiain ^■Eijtiptlaann, Willd. is well 

 settled in many of our streets, a somewhat northerly station I believe. — Pkok.

DiARKiiENA Amkkicaxa, Bcauv. — Last summer while collectiny: SuUivantin 

 Ohinnis, T. & G. in Clifty Ravine, a gorge running back from the Ohio River, 1 

 noticed large bunches of a beautiful grass growing along the side of a narrow foot- 

 jjath running at the foot of some high cliffs. The leaves Avere large and brilliant 

 green and grew in dense tufts at the base of a long weak culm, bearing at the top 

 a few spikelets. The species proved to be D. Americana, Beauv., a new grass for 

 this neighborhood. There are one or two characteristic features about it, in addi- 

 tion to those mentioned in Gray's Manual, that may be of interest to botanists. 

 The margins of the leaves and the axis of inflorescence are roncih backwards, almost 

 as much so as the stems of some sjwcies of Galhtm. Tiie prominent nerves on tin- 

 upper surface of tlie leaves and tlie glumes are also rough backwards, but rather 

 less so. The under surface of the leaf is smootli and lighter in color than tln^ up- 

 per. This species was growing in shady, damj), limestone soil and the tufts Averc 

 as close together as tliey could stand, with some culms at least four feet long. At 

 the top of the cliff", and running back upon the flat lands, KulUntjiapumila, 3Iichx. 

 grows in the greatest profusion, sonietimes forming a dense carpet over tlic ground 

 for rods. — Ed. 



Euphorbia .mai!(.ixata, Pursh. — Tliis western Euphorbia has become thor- 

 oughly naturalized in tliis neighborhood. Acres of it gi'ow upon the gravelly hills 

 about JIadisou, n\aking tJieni look as if covered with white blossoms. The plants 

 are strong ami thrifty, some attaining a heigiit of more than three feet and' pro- 

 fusely brandling. It seemed to make its appearance quite suddenly a few j'ears 

 ago, but is spreading with wonderful rapidity, covering onlj' such hills and jiarts 

 of hills as have been cleared of timber and are covei-ed with sand and gravel. Its 

 special fondness seems to be for some old raili'oad ctits where piles of debris have 

 been thrown out, and, weathering, l)av(^ made a soil of suitable composition, it 

 tlius shows its fondness for tise great sandy plains it has left so far to the west of 

 us. — Ed., 



Notes ox some jxtkiiestixc I'Eaxts koixd j\ Jeefersox C'ouxty. — Tii our 

 <unnner cxcuisions we have found (]uite a nnmbii- of plants either of local occur- 

 rence, unreported range, or rare, the reporting of which we have thougiit would 

 l)rove of interest to Botanists. Hydrastis Canadcnt'is. E., has been observed in (_[uitc 

 a number of ))laces, but its abundance upon the liills of the Ohio River seems to 

 designate tlicin as a place most favorable for its growth. In all our observations 

 w.- have rarely found an isolated individual of this species, ))ut it usually ai)pears 

 in small patches of 50 to 100 individuals. 



J'ulaiiisia ijraveolens, Raf. abounds along the roadsides near the i-iver. It nearly 

 always liears two, and often three sorts of leaves upon the same steni. The usual 

 specimens bear simple oblong to ovate leaves in tlie tipper i>ortion of the plant, 

 s(unetiines sm-ceeded by binate leaves, while the lower are nearly always ternate. 

 We notice Viola lanceolata, L. credited in the Manual of Botany to a greater abun- 

 dance eastward than westward, but the quantity here is remarkable, it being not 

 unconnnon to sec a plot of one or two acres white with its blossoms. Some speci- 

 mens of this species seemed to me so remarkably large that I measured a few. I 

 found six to seven inches to be quite a common length, while I have one before me 

 whose scape is nine inches long. Three years ago the writer collected at the 

 •'Knobs,'' about thirty miles distant, some specimens of Lechea minor, Lam.
