SCARLET TRUMPET 



JACOB S LADDER 



Scarlet Trumpet (Gilia). This plant has a 

 limited distribution in the Park, growing only in the 

 southern part, in the upper Snake Biver valley. It is 

 confined to dry, gravelly, sagebrush-covered soil. The 

 rather freely branching stem is usually about two feet 

 high. The leaves are finely divided, like carrot leaves, 

 and have a pungent, spicy odor. The flowers, borne 

 in threes and fours along the upper part of the stem, 

 are long and very narrow scarlet trumpets, dividing 

 at the end into five flaring points. They are in bloom 

 during July and the first few days of August. 



Jacob's Ladder (Polemonium) . The Jacob's lad- 

 der occurs widely scattered through the Park, in moist, 

 partly shaded places. The stems are slender and rath- 

 er weak, bending or partly sprawling. The leaves 

 are compound, with from seventeen to twenty-one 

 small, lance-shaped leaflets along the central stalk. 

 The flowers are grown in clusters at the ends of slen- 

 der flower-stalks; they are somewhat cup-shaped, with 

 five petals, and are of a delicate light blue. Blossom- 

 ing is over early in the season at the lower levels, but 

 persists well into July at higher elevations.
