plant of Camptosorus. In the large fissures or caves in the rocks 

 plants of the Heuchera are found growing farther from the light 

 than any of the other shade-loving forms. 



Sedum telephioides Michx., a plant of the southern Appalachian 

 region was found in August, 1902, in Pope County, where it 

 grows in the thin soil at the tops or on ledges of sandstone cliffs. 

 While this was its first collection in the state, it is also interesting 

 as an example of plant distribution. The migration route by 

 which it has reached Illinois is evidently across the hill region of 

 southern Ohio, the Knobs of Indiana, and the Ozark Hills of Illi- 

 nois. This affords a continuous route along which the plant 

 might find conditions resembling those of the mountains from 

 which it came.

In the sudden death of Miss Louise Brisbin Dunn, tutor in 

 botany in Barnard College, which occurred on December 18, 

 the department with which she has been so long identified has

 was then under the direction of the late Professor Emily L. 

 Gregory. Becoming interested in the regular college work, Miss 

 Dunn made up that winter the amount of Greek required for en- 

 trance and matriculated as a regular student in the fall. She 

 was graduated in the spring of '97 with the highest standing at- 

 tained by any student in the college up to that time. She was of 

 course among those who were elected to Phi Beta Kappa when 

 a chapter of that organization was established in the college three 

 years later. After her graduation Miss Dunn was appointed 

 assistant in botany in Barnard College, and during that year and 

 the next carried on work in botany, zoology and chemistry 

 leading to the Master's degree, which she received in June, 1899. 

 At that time she was also advanced to the rank of tutor, which 

 position she held at the time of her death. In the summers of
