 (Vol. II, p. 104), a nominal list of 101 species of plants found 

 in Arkansas, not included in Lesquereux's catalogue, is given,

Harvey' s work. — From 1875 to 1885, Professor F. L. Harvey r 

 then at the Arkansas Industrial University at Fayetteville, 

 made extensive collections of plants, which have found their 

 way to many of the larger herbaria of this country and Europe. 

 His private herbarium was purchased by the University, where 

 it is preserved. A complete account of his collections has 

 never been published, but the herbarium at Fayetteville has 

 been carefully examined and its Arkansas species included in 

 the plant list of the state, the nomenclature being revised. 

 Professor Harvey has, however, written several shorter articles 

 that refer to the botany of the state. 



" The Forest Trees of Arkansas, American Journal of For- 

 estry, June and July, 1883." Also reprinted separately, pp. 1-20. 

 This article gives a list of 120 species of arboreal plants, with 

 an accouiv. of their distribution in the state. 



Many notes on the occurrence and distribution of species 

 are given by Professor Harvey in the Botanical Gazette, as fol- 

 lows : Vol. V, pp. 15, 39, 84, 91, 139; Vol. VI, pp. 189, 213,
