PLANTS OF WHITE COUNTY— VI. 



Louis F. Heimlich, Purdue University. 



The following is a list of 53 additional species and varieties of the 

 White County, Indiana, flora. This makes a total of 440 species of wild 

 plants of the county reported by the author. The collection dates were 

 June 1 and August 22, 23, and 24, 1923. 



In the list given below the grasses were identified by Agnes Chase 

 of the Bureau of Plant Industry, Washington, D. C. All other species 

 with the exception of numbers 840, 855, 870, and 900, were identified 

 by C. A. Weatherby of the Gray Herbarium, Harvard University. A 

 number of specimens of greater interest and the ones as recorded as 

 new to the state or rare have been reviewed by C. C. Deam of BlufFton, 

 Indiana. 



It is believed that the following seven species and varieties in- 

 cluded in the general list below are new to the state or are of rare 

 occurrence. 



Potaivogeton americanus C. & S. var. novaehoracensis (Morong) Benn. 

 No. 864. Collected in Tippecanoe River just north of the dam at 

 Monticello, east side, Aug. 23, 1923. New record. 

 Polygonum ramosissimum Michx. forma atlantiaiDi Robinson, (Poly- 

 gonum atlanticum Bicknell). No. 858. Collected along the Monon 

 Railroad, north of Reynolds, near Little Honey Creek bridge, Aug. 

 22, 1923. New record. See figure 2. 

 PoteyiHlla canadensis L. var. simplex (Michx.) T. & G. No. 830. Col- 

 lected in alley, east part of Reynolds, June 1, 1923. New record. 

 See figure 1. 

 Geum virginianum L. var. Rhirrayanum Fernald. No. 854. Collected 

 along bank of Little Honey Creek, near Monon Railroad bridge, 

 Aug. 22, 1923. New record. See figure 3. 

 Rubiis flagellaris Willd. {Rubus procumbens Muhl.) No. 831. Com- 

 mon in a dry sandy field, east part of Reynolds. Collected June 1, 

 1923. New record. See figure 4. 

 Baptisia bracteata (Muhl.) Ell. No. 836. Collected along Pennsyl- 

 vania Railroad, east of Reynolds, June 1, 1923. Growing on high, 

 sandy soil. According to Deam this is a rare plant, heretofore re- 

 ported only from Steuben County, but lately collected by Deam in 

 Lake, Porter and Laporte counties. 

 Helianthiis petiolaris Nutt. No. 868. For years I have seen this species 

 growing on dry sandy soil to the east of the dam at Monticello and 

 did not suspect that it was a rare plant in our state. It is a western 

 species and apparently has only been noted twice before in two 

 western counties of the state (Tippecanoe and Lake). See figure 5. 

 Sparganiaceae. 

 Spargawum eurycarpum Englem. Broad-fruited bur-reed. No. 855. 



Najadaceae. 

 Potamogeton americanus C. & S. var. novaebor-acerisis (Morong.) Benn. 

 Variety of the long-leaved pondweed. No. 864.
