4b. Aureolaria pedicularia var. ambigens (Fern.) Farw. (Gerardia 

 pedicularia var. ambigens Fern, and Dasy stoma pedicularia in part, of 

 Britton and Brown, Illus. Flora, ed. 2.) Map 1867. This variety is infre- 

 quent in northern Indiana and its range probably can be extended only 

 to a few counties adjacent to those shown on the map. There are re- 

 ports from Tippecanoe and White Counties. It is found only in very sandy, 

 slightly acid soil. It usually grows in oak woods in low areas surrounded 

 by Vaccinium angustij olium or in somewhat moist, rarely dry, sandy places 

 near the bases of oak slopes.

7622. BUCHNERA L. 



1. Buchnera americana L. Map 1868. This plant is extremely rare in 

 Indiana. The only recent specimens are from the low dunes near Lake Mich- 

 igan in Lake and Porter Counties. It formerly was frequent on the low 

 dunes at Pine, now the north end of Clark Street in Gary, but in 1935 

 search was made for it and only a few plants were seen. It will soon be 

 extinct at this station, and only a few plants have been seen in Porter 

 County. In the Wabash College herbarium are two sheets collected by 

 Dr. A. Clapp Aug. 6, 1835, in the "barrens" (in Floyd or Harrison Coun- 

 ties).

7631. CASTILLEJA Mutis 



1. Castilleja coccinea (L.) Spreng. Indian Paintbrush. Map 1869. 

 This is an infrequent to rare species in the lake area with a few reports 

 from the southwestern border of the state. It grows in moist, sandy, 

 slightly acid soils, usually in marshes or wet prairie habitats. It is gen- 

 erally found in small colonies, but I saw acres of it in a drained marsh 

 that had been closely pastured for a few years. It is still somewhat fre- 

 quent on the borders of sloughs between the low dunes near Lake Michigan
