IV PLANTS BAKERIANyE. 



The statement that all plants in the '99 sets from this 

 locality were taken during April or the first few days in 

 May has seemed surprising, even to those best acquainted 

 with collecting in the southwest. Summer and fail collect- 

 ing in this locality would unquestionably give very inter, 

 esting results. 



During the early days of May camp was moved far up 

 the valley of the Rio de los Pinos to the lower end of Gra- 

 ham's Park at an altitude of 7,800 feet. Here the results 

 of a cold, dry spring were very evident, and collecting was 

 poor. 



On the 15th of the month camp was moved down the 

 valley to Los Pinos P. 0. (also known as Bayfield) on 

 the same river, at about 7,000 feet altitude. This place is 

 just north of the Ute Reservation line, and on the zonal 

 division between Pinus edulis (pifion) and Pinus ponderosa. 

 Here were still further signs of drought. Collecting was 

 necessarily largely confined to the river bottoms and ground 

 moistened by seepage from irrigating ditches. 



On June 1 camp was moved to Arboles, in the river bot- 

 tom at the junction of the Rio San Juan and Rio Piedra, 

 only a few miles above the New Mexican border. Collections 

 were made here and also at Rosa, New Mexico. Numerous 

 large flocks of sheep were rapidly devastating the narrow 

 bottoms. The destruction could scarcely have been more 

 complete had the work been done by fire. A number of 

 very interesting plants were found among the very dry 

 sandy hills and along the stony mesa banks, among them 

 a new Coleosanthus, two new Astragali, and a new Carduus. 

 As at Aztec, these hills are covered sparsely with pinon, 

 pine and cedar, though otherwise the two localities are very 

 distinct. 



The next move made was up the Rio Piedra to Piedra
