MONTANA BOTANY NOTES 43 



short tails, pedicels longer than the fruit, plants mostly pubescent. This 

 is represented in the interior more by the form obtusa, with smooth foliage 

 somewhat larger and more pointed and narrower leaflets. All the species of 

 Osmorhiza have the two forms of leaves, broad and deeply serrate or lobed 

 leaflets, and lanceolate and less lobed and shallow serrate leaflets, which 

 occur indifferently with the varying fruit characters. In the shade the leaf- 

 lets are larger and more pubescent, in the sun they are much reduced, 

 thicker and nearly smooth. Typical O. divaricata is characterized by the 

 nearly linear beaked fruit with tail from nearly equal to half the oody, pedi- 

 cels nearly as long as the fruit (the central one often 1-2 inches long), large 

 and acuminate leaflets, stylopodium longer than wide, plants nearly smooth.
