Kerrville, and one trip up Town Creek for a distance of about seven 

 miles. 



For at least twenty-five miles on all sides, and for many more in some 

 directions, the same limestone formation prevails, and plant life appears 

 to be pretty uniform throughout. Having found by experience that long 

 trips yielded practically the same things which I could find within a 

 radius of a mile from Kerrville, I directed my attention to thoroughly 

 exploring a small area, dividing the time so that each particular place 

 was visited once a week. 



The steep, stony, left bank of the river for a distance of about one- 

 fourth of a mile took up at least two days of the week, Town Creek one 

 or two, and the hills the balance of time. To the best of my knowledge, 

 horehound, which is abundant about the streets, and a species of Juniper 

 occasionally met with along Town Creek, are the only plants found in 

 flower or fruit between the middle of April and the first of July that I 

 did not collect. 



The characteristic plants of the limestone region in Kerr county are 

 many. In fact the bulk of the species are plentiful over the whole area 

 at certain elevations. At no place is there a greater range of more than 

 400 feet between the lowest and the highest elevations, yet a number of 

 species growin'g abundantly on all the hilltops are not found at the lowest 

 elevations, and some of them only on the summits. Acacia Roemeriana, 

 Coreopsis Drummondii Thelesperma filifoliiim, B if or a Americana, and 

 Brazoria scutellarioides are examples of the hilltop flora. A few of 

 those found at both the highest and lowest elevations are Lesquerella 

 recurvafa, Kuhnistera pulcherrima. Cassia Roemeriana and Erigonum 

 longifolium. Along streams, the dwarf walnut, Juglans rupestris, is 

 very plentiful. 



Three trips were made to San Antonio, with very satisfactory results, 

 the rich, moist ground along the river banks always producing an 

 abundance of plants. 



In all, 573 numbers were collected, only a few of them being dupli- 

 cated. Of these, 39 were collected at San Antonio, 4 at Kenedy, Carnes 

 county, 8 at Waco, McLennan county, 248 about Corpus Christi, and 

 299 about Kerrville. 



The orders represented by the largest number of species are Com- 

 positae and grasses, of which some 60 species each were collected. 

 Texas is very prolific in grasses, but they grow in scattered clumps or as 

 solitary plants, rarely forming a sward, as they do further north. The 

 Leguminosae are represented by over 50 species, many of which are
