distribution. Also when planted in a favorable habitat, it freely escapes. 

 Notable examples of its escape are on the knobstone in northern 

 Washington County, on the bluffs along Raccoon Creek in Owen County, 

 and in Monroe County in a grove about 4 miles northwest of Ellettsville 

 and about Weimer's Lake 2i/ 2 miles west of Bloomington where it has been 

 established for more than 50 years. A colony of about 3 acres in Orange 

 County about 8 miles southeast of Paoli and just north of Danner's Chapel 

 originated from a tree planted in the church yard. Some of the trees have 

 already been cut for saw logs. R. M. Kriebel reports several large colonies 

 in Lawrence County. He has traced the origin of each colony to a planted 

 tree. In the knobstone area this species is truly "an old field" species. 

 Within a 25-year observation I have seen it cover abandoned fields although 

 it is a species difficult to transplant.

24. LARIX [Tourn.] Mill. Larch 



1. Larix laricina (DuRoi) Koch. Tamarack. Map 63. Infrequent to 

 frequent in bogs and on the low borders of lakes and streams throughout 

 the lake area. It was formerly more or less common in many places that 

 have been drained and are now farmed. It has suffered much during the 

 past few years due to drought and is becoming scarce because of drainage 

 and cutting.

1. Tsuga canadensis (L.) Carr. Eastern Hemlock. Map 64. Local 

 in the state and usually restricted to a fringe of trees on the tops and 

 slopes of high sandstone bluffs along streams. Rapidly disappearing in 

 some of its stations.
