It was the acceptance of the ranges cited by Gray which caused 

 the limitation by me of the native habitat of the plant to the 

 western prairies. I find, however, on reference to Dr. Darling- 

 ton's Florula Cestrica, that the plant is recorded from Chester 

 County, Pa., in 1826, though it is there said to be not common. 

 In the third edition of the Flora Cestrica, 1853, it is recorded by 

 Darlington as growing in " fence-rows and thickets, not common." 



In 1857, Dr. Knieskern records it in his Catalogue of Plants 

 of Monmouth and Ocean Count} 7 , New Jersey, as occurring in 

 dry fields, not common. In the Catalogue of Plants of New 

 Castle County, Delaware, published in 1844, the species is ad- 

 mitted without question. In Dr: Aikin's Catalogue of Plants of 

 the vicinity of Baltimore, Md., 1837, the plant is said to grow in 

 bushy meadows. According to Dr. Curtis' Catalogue of Plants 

 of North Carolina, 1867, it is said to grow in all the districts of 

 that State. In Dr. Elliott's Botany of South Carolina and 

 Georgia, 1824, it is recorded as growing in dry sandy soil. 



It seems to me from the above citations that the point made 

 by Mr. Moore is we'll taken, and that there is no evidence that 

 the species is not native on the Atlantic sea-board from Maryland 

 or, perhaps, Pennsylvania, southward ; that it has, however, been 

 introduced, as Dr. Gray suggested, presumably from the West, 

 into New York and New England, seems from its recorded his- 

 tory, equally certain. 



SEEDLINGS OF ARISAEMA 



By D. T. MacDougal 



The writer has had the seedlings of Arisaema tripkyllum and 



A. Dracontium under observation for some time in etiolation 

 experiments and some facts of independent interest have been 

 gathered and are presented here. 



The general facts concerning the germination of A. tripJiyllum 

 are familiar and need be recounted only briefly. The cylin- 

 drical cotyledon pushes out of the seed coats in about six
