210 BOTANICAL GAZETTE. 



several of T. hradeata have thrown up long spikes and blossomed — though 

 much later than in their native clime. From the lot I selected a 

 cluster of T. ccespitosa, Leconte, for my dry herbarium, thinking that it would 

 dry out- But I noticed after some time that the plant seemed green, so 

 I tied its roots upward to a rafter, where it was deprived entirely of mois" 

 ture. And now after nearly six months it has assumed a thoroughly live 

 appearance and increased in growth amazingly. By spring it will no doubt 

 blossom. The long moss, T. usneoides, of which I hung'quantities on my 

 cherry trees in the yard, has grown very fast all summer and I dread the 

 approach of frost, when it must succumb to the rigors of our northern 

 climate. — W. W. Calkins 



Nomenclature in Atlantic U. S. PolypetaljE. — The article in the 

 Gazette for August, p. 193, noting changes in the names of the Poly- 

 petalai of the Manual, as indicated in Watson's Bibliographical Indexj 

 brings to view an error in that carefully prepared index, either clerical or 

 typographical, which has till now escaped detection. The Gazette notes 

 ^^Cardaviine rhomloidea, var. purpurea, Torr., is C. rotundifolia, Mx." Those 

 who know the two plants will not need to be told that this is wrong. The 

 three synonyms adduced under C. rotundifolia in the Index must have been 

 accidentally inserted under that species, instead of under C. thomboidea. 



There are a few other names in the list in respect to which the Index 

 hardly gives the last word. Although the question is a nice one, the author 

 of the Index would on reconsideration, probably prefer Spergularia to 

 Zepigofjum; the change of Sullivantia Ohionis into S. Ohioensis was acci- 

 dental; Daliba7-da repens {pace Benth. & Hook.) will probably stand as the 

 type of a good genus; and whoever uses the Linnaian name of Vitis arborea 

 for a species which is not arborescent is not entitled to forego Epilobimn 

 afigusiifoliujH, L. , (well enough named in contradistinction to its relative 

 E. laiifoHum, L.,) in behalf of the much later E. spicatu?n of Lamarck. 

 Apparently the same rule should govern the two cases. — A. Gray. 



Flora of Dallas County, Texas. — It has been my bad or good for- 

 tune to live in this little corner of the world for twenty years, but it is 

 only for ten years that I have given earnest attention to botanical pursuits. 

 During that time I have collected carefully all the plants I have found 

 in the countr}'. Yery few I think can have escaped my constant search, 

 so that the following figures may be considered correct. There are 839 

 indigenous species, to which must be added 66 introduced species that have 

 taken such a foothold that they may be considered indigenous, making a
