DICOTYLEDONOUS PLANTS 151 



lobes linear. Corolla deep yellow, fading whitish, an inch or more long, 

 with 3 large sacs. This blooms later than the others. Throughout 

 California. 



There are many species besides these. 



VII. PEDICULA'RIS 



Perennials with one to several stems from a thick root. 

 Leaves pinnately divided or lobed, the divisions often toothed, 

 cleft, or divided. Calyx 2-5-toothed, irregular. Corolla 

 2-lipped, the upper arched and compressed on the sides, some- 

 times with a beak; the lower erect at base, 3-lobed, and with 

 2 crests above. Stamens 4, in the long upper lip. 



P. densiflo'ra Benth. INDIAN WARRIOR. Leaves twice pinnately 

 divided, with the divisions sharply and irregularly incised. Stem 

 and leaves dark-red when young, becoming greener with age. 

 Flowers an inch long, crimson, in a dense spike that lengthens in 

 fruit. Common in western and middle California. 



VHI. MIM'ULUS, Monkey Flower 



Herbs, or one species shrubby, with opposite, simple leaves 

 and showy flowers on axillary peduncles. Calyx bell-shaped, 

 5-toothed, and with as many folds and angles, often oblique. 

 Corolla with the tube included in the calyx and the border with 

 5 round, spreading lobes arranged so that 2 form the upper lip 

 and 3 the lower. Within the tube are two ridges flattened on 

 top, running down the lower side of the throat. Stamens 4, 

 with the anther cells diverging. Stigma 2-lobed, with spread- 

 ing parts, often somewhat shield-shaped. When an insect 

 alights it touches the stigma, which immediately closes, the 

 2 lips folding together ; the anthers are thus exposed, so that 

 the insect becomes dusted with pollen. This can be observed 

 by touching the stigma with a pencil. 



a. M. cardina'lis Dougl. RED MONKEY FLOWER. Stout,' 2-4*ft. 

 high, viscid-pubescent. Leaves sessile, ovate, dentate, 2 in. long. 

 Corolla scarlet, 2 in. long, with all the lobes except the upper one reflexed. 

 Stamens projecting from the corolla. This grows along streams. 

 Widely distributed.
