cites for his aiithonty Bot. Gaz. Vol. 27: Apr. 1899. The article referred 

 to is Cowles' article on the flora of the sand dunes of Lake Michigan, in 

 which he discusses the flora from Glen Haven in northern Michigan to 

 Dune Park, Indiana in Porter Gounty, which has confused Heimlich 

 in separating the trees reported at several stations. It has never been 

 found in Indiana. 



Chaniaecyparis tliyoides (Linnajus) Britton, Sterns and Poggen- 

 berg. White Cedar. The range of this species is east of the Alleghany 

 mountains and no doubt was never native in our area. The first 

 reference to it is by Dr. Drake in his Picture of Cincinnati, published in 

 1815, page 83, in which he says: "The White Cedar and Cjqoress are 

 found on the banks of the Wabash." Schneck^ in his Flora of the Lower 

 Wabash Valley says: "Wet places near the mouth of the Wabash 

 River." I am certain it is not on the Indiana side of the river. Gorby^ 

 reports it for Miami County. All of his botanical records are too un- 

 reliable to receive serious consideration. Coulter' reports it as found in 

 Allen County on the authority of Dr. C. II. Dryer. I saw Dr. Drj-er 

 recently and he saj^s he has no recollections about it. 



Juniperus communis Linnaeus. Juniper. This species has lieen 

 reported from all parts of the State. The distribution of the species 

 is to the north of Indiana, and examining herbarium specimens it is 

 found that subulate forms of Juniperus virginiananre frequently named 

 Juniperus communis. In the older floras it was a custom to include 

 cultivated forms, and not distinguish them as such. Since juniper has 

 been for years a common ornamental shrub, especially in cemeteries, 

 it is highly probable that many records have such a basis. It is proposed 

 to drop this species from our flora. I refer Higley and Raddin's"" record 

 to the decumbent variety. VanGorder's and Bradner's records may also 

 be the decumbent form. Heimlich's record I regard as an error, see 

 remarks under Abies halsamea. 



Populus balsamifera Linnaeus. Balsam Poplar. This species 

 was reported by Bradner for Steuben Gounry. In a letter from the 

 late Prof. Bradner, he said he had no specimen and had no recollection 

 of the tree. J. M. Coulter reported it for Jefferson Count}^, but Young 

 who also wrote a flora of Jefferson County does not mention it. Baird 

 and Taylor also reported it for Clark County. The last two records may 

 have been from cultivated trees or mistaken for Populus grandidenfata 

 which was not reported and is in the area, and is a frecjuent tree in the 

 "knobs" in Clark County. Heimlich reports it in Proc. Ind. Acad.
