L. assurgentiflo'ra Kellogg. This grows to a height of several feet, 

 and has large reddish purple flowers, veined with darker lines. 



II. SIDAI/CEA, Rose Mallow 



Perennial or annual herbs. Leaves round in outline, lobed 

 or parted. Flowers rose-color, in a terminal raceme or spike. 

 Calyx with outer bracts wanting. Column of stamens double. 

 Carpels 1-seeded, indehiscent. 



a. S. malvaeflo'ra Gray. Perennial with several stems from the 

 root 1-2 ft. high, erect or ascending, hairy. Root leaves rounded, 

 deeply crenate ; stem leaves 7-parted, with the divisions 3-lobed. 

 Flowers in spike-like racemes, rose-color. Carpels becoming some- 

 what wrinkled and veiny when ripe. There are two kinds of flowers. 

 Those with rudimentary anthers are smaller and generally of a 

 deeper color ; the perfect flowers are an inch or more across. The 

 pistils ripen after the pollen is discharged. This is variable and 

 common near the coast. 



b. S. Orega'ng. Gray. Perennial. Stems solitary or few from 

 the root, 2-6 ft. in height, branching into panicles which are stel- 

 late pubescent. Leaves chiefly at the base, orbicular in outline, 

 7-9-lobed, the lobes cleft. Flowers | 1 in. long in spicate 

 racemes. Carpels slightly beaked, smooth. From northern Califor- 

 nia to Oregon. 



c. S. diploscy'pha Gray. Annual, with hairy stems 1-2 ft. high ; 

 branches spreading. Leaves round-kidney-shaped, the earliest 

 crenate, the others with 5-7 lobed divisions. Petals pink, an inch 

 long. Carpels veiny and wrinkled, depressed, beakless. This is com- 

 mon in middle California in fields, growing like a weed. It is one 

 of the most beautiful species.
