Lupine (Lupinus). The lupines are among the 

 most striking and handsome of all the flowers in the 

 Park. They are found at all levels, in open and partly 

 shaded situations, preferring gravelly, well-drained 

 soils. The stems are stout and erect, from one to three 

 feet high, ending in the flower spike. The leaves are 

 compound, with from five to ten narrow, entire-edged 

 leaflets arranged finger-fashion. The pea-shaped flow- 

 ers, usually bright blue, but sometimes marked with 

 white or even entirely white, are thickly clustered 

 around the axis of the spike. They are in bloom from 

 June until September. 



Licorice (Glycyrrhiza) . This plant is frequently 

 found along the roadsides, especially in the lower 

 levels of the Park. It has rather stout stems about 

 two feet high, bearing quantities of smooth, green 

 compound leaves, with from eleven to nineteen oval 

 leaflets. The flowers resemble those of the pea, but 

 are somewhat narrow and long. They are grouped 

 in dense clusters at the upper ends of the flower 

 stalks, which rise from the axils of the leaves. They 

 are yellowish-white in color, and their season lasts 

 from early July until late August. The pods are cov- 

 ered with hooked prickles, so that the plant is some- 

 times called "burr-pod."
