are abundant (no. 2471). Only a few feet above, but in the 

 shade of larger plants, occurs a form (no. 2472) in which the 

 stems are twice as high, the internodes elongated, the stems and 

 leaves more nearly glabrous, the upper sessile nearly orbicular 

 leaves much thinner and larger (li in. long), and the peduncles 

 more elongated. No difference in the floral characters could be 

 detected, except that the flowers in the latter form were somewhat 

 larger than in the other. 



Mimulus moschatus longiflorus Gray. 



Near streams throughout the Transition Zone. (No. 805.) 



Mimulus Palmeri Gray. 



This species occurs rather rarely in damp sand and along the 

 streams up to an altitude of 6000 ft., often accompanied by M. 

 Fremonti. (No. 2230.) 



On examining these specimens it was noticed that in all cases 

 the style was pubescent. This was unexpected, since one of the 

 characters used to distinguish the section Eumimulus, to which 

 the present species belongs, from Eunanus is that of the glabrous 

 style. An examination of all the material at hand (some fifteen 

 sheets) of M. Palmeri was therefore made, with the result that a 

 majority of the specimens were found to have pubescent styles. 

 Certain other characters were found varying somewhat parallel 

 with this. The following forms may be distinguished: 



faj Style glabrous, filaments glabrous, anthers ciliate, calyx- 

 lobes acutish and ciliate. The following collections belong here: 

 San Bernardino Mts., June, 1892 (S. B. Parish, no. 2443); San 

 Antonio Mts., June, 1900 (H. M. Hall, no. 1449); Sequoia 

 Mills, Fresno Co. (T. S. Brandegee). In the last, however, the 

 anthers are glabrous. 



fbj Style pubescent, filaments pubescent, anthers glabrous, 

 calyx-lobes very obtuse or truncate, cuspidate and not ciliate. 

 The following belong here: San Jacinto Mt., June, 1897 

 (G. F. Reinhardt); Palomar, May, 1901 (W. L. Jepson and 

 H. M. Hall, H. M. H. no. 1959); San Jacinto Mt., May, 1899 

 (H. M. Hall, no. 1281); San Jacinto Mt., June, 1901 (H. M. 

 Hall, no. 2230). In the last the calyx-teeth are occasionally 

 beset with a few ciliate hairs.
