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. 



VH. PEDICULATUS 



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.

Vm. MDSTULUS, 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 ivith the tube included in the calyx and the border with 

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

 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.

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