Subsequently, five more specimen collections were 

 made to include the observed variation of this 

 site, and additional Aquileqia collections were 

 made from surveyed locations across the Lewis & 

 Clark National Forest. 



Morphologic measurements were completed on pressed 

 specimens, and sepal color observations were made 

 before collection and after pressing and drying. 

 Only one measurement was taken for each character 

 on each specimen. This information is presented 

 in Table 1, p. 13. Similar information was 

 obtained for Aquileqia specimens collected from 

 other locations on the Forest. Utilizing the keys 

 and descriptions presented by Scoggan (1978), Moss 

 (1983) and Munz (1946), a matrix of characters 

 that are associated with A. brevistyla and A. 

 f lavescens was organized in table form. Table 2, 

 p. 14. Individual characters of each specimen 

 were then scored with respect to the matrix (Table 

 3, p. 15). Thus, the character of sepal color for 

 a specimen was scored as either falling into the 

 description for A. brevistyla or A. f lavescens , or 

 if it did not clearly fit into either, (such as 

 yellow when collected, blue when pressed) as 

 intermediate. Finally, a composite score was 

 given to each specimen (bottom of Table 3, p. 15). 

 Collection sites for these specimens are marked on 

 portions of a reduced reproduction of a USDA 

 Forest Service map of the Lewis & Clark National 

 Forest, Figure 2 (p. 16), and 3 (p. 17). 

 Specimens are deposited as detailed under 

 Documentation, Section I.I., p. 20. 



Only at Dry Pole (001) was the distribution of A. 

 f lavescens actually observed to overlap with A. 

 brevistyla . Six specimens (442 1-6) were 

 collected from this site. Of these, specimens 

 442-2, and 6 best fit the description of A. 

 brevistyla according to the matrix (Table 2) , 

 while specimens 442-3 and -4 fit the description 

 of A. f lavescens . Specimens 442-1, and -5 each 

 were given composite scores of intermediate (to A. 

 brevistyla and A. f lavescens ) . Specimen 442-1 had 

 blue sepals, a short style, and stamens that were 

 barely exserted; all characters representative of 

 A brevistyla . However, this specimen also had 

 long and wide sepals, and petals that were less 

 than half the length of the sepals, characters 

 that better fit the description for A. f lavescens . 

 Specimen 442-5 was collected yellow but dried
