744 REPORT OF STATE GEOLOGIST. 



Probably to be found in all parts of the State if looked for in June 

 and July. 



Flowers from June until in August.

MAGNOLIACE^E. Magnolia Family. 



MAGNOLIA L. 



M. acuminata L. Cucumber Tree. 



Found native in sparing numbers in the counties fronting the 

 Ohio Eiver. It is usually found in moist, alluvial soils. It is 

 largely cultivated as an ornamental form in lawns and parks, and 

 has proved itself able to withstand the rigors of winter as far 

 north as Tippecanoe County. 



Flowers in May and June. 



Jefferson and Tippecanoe (Coulter); Putnam (MacDougal). 



LIRIODENDRON L. 



L. Tulipifera. L. Yellow Poplar. White Wood. Tulip Tree. 



Indicative of rich soils and formerly largely distributed 

 throughout the State. In the early history of the State it was 

 one of the most numerous and largest of the forest trees. It 

 reaches its greatest development in the valley of the lower Wabash 

 Eiver, but is being rapidly exterminated. Dr. Schneck gives the 

 following measurements of a specimen in Gibson County: "Cir- 

 cumference above roots and swells, 25 feet; height of trunk from 

 roots to first branch, 91 feet; total height, 190 feet." A measure- 

 ment of 150 specimens in Jefferson County gave an average diam- 

 eter of three and one-half feet at three feet above the ground, and 

 and average height of 87 feet. The tree from an economic stand- 

 point is one of the most valuable occurring in our area, and this 

 high value has led to its practical extermination. I have observed 

 it growing freely in second growth timber in the southern coun- 

 ties, a fact which suggests that it would well repay culture. Cattle 

 can not be pastured in a poplar grove without damage to the trees. 

 Where areas have been heavily pastured for a few years, all the 

 poplars, even the largest forms, have been killed. 



The flowering season is in May and June.
