as early as February 20. He thinks it clearly biennial and would be 

 glad to know from other observers whether it is always so. 



Sisymbrium Thaliana, a little later flowering than the Draba, is also 

 biennial. In the first week of March it was just beginning to show 

 flowers. 



Erythr.'ea Centaurium. — In the summer of 1878 I discovered 

 three or four fine plants oi Erythrcca Centaurium, Pers. , nicely in blos- 

 som, on the grounds of the Agr'l Coll., Lansing, Mich. Some time 

 before this Prof. Beal found specimens of the same in an open swamp 

 near by. None have been found in the locality since '78. 



HydrocotyJe umbellata, L , also occurs near here on the shores of 

 small lakes. —L. H. Bailey, Jr. 



Some Plants of Franklin Co., Kv.—For more than a year past I 

 have been indebted to your Gazette for many little things of great 

 interest to me, and I feel that I ought to make some return (or strive 

 to do so) by giving you some of my notes on last year's collecting in 

 this county (Franklin), premising, however, that I am a beginner in 

 botany. 



Hepatica triloba and acutiloba are both found on the Lower Silurian 

 limestone hills or cliffs of Kentucky River, the latter species more 

 common and often seen with the lateral lobes of the leaves again 

 slightly lobed. 



Isopyruni biternatum, T. & G., occurs in similar situations, but is 

 more rare. 



Hydrastis Canadensis, L. , is common in rich woods and often has 

 an additional leaf, three lobed, just below the flower, making three 

 leaves on the stem. 



Menispermum Canadense, L., is common, but it is rare to find a 

 specimen with a woody stem nearly an inch in diameter. 



Podophyllum peltatum, L., I found once with but one leaf on the 

 flowering stem. I thought it rather interesting to find on one cliff at 

 some distance from any dwelling three introduced plants, viz. ; P<i- 

 paver somniferum, L., Bupleunan rotundifolium, L., and Vinca minor. 

 The latter covers a large portion of the wooded hill side, while the 

 former grew scattered among the loose stones near the base. How 

 the Bupleunim got there I cannot imagine, as I have never seen it 

 anywhere else in the county. 



Cardatfiine rhomboidea. var. purpurea,ToTX., is common in rich soil at 

 the base of the limestone cliffs. 



Arahis patens, SuUiv. is found in the same situations, but is not com- 

 mon. 



Vesicaria Shotiii, T. & G. , is quite abundant in a few localities in 

 similar situations to the above. 



Lepidium intermedium, Gray, is rare in dry woods. 



Solea concolor, Ging, occurs abundantly in the rich soil on the river
