 nate or stellate hairs on leaves and calyces; leaves orbicular, 1-6 cm. broad, crenate 

 to shallowly 5- to 9-lobed, the lobes crenate; upper leaves 3- or 5-divided, the seg- 

 ments entire or 2- to 5-lobed and ciliate; inflorescence racemose, many-flowered; 

 rachis glabrous to sparsely hirsute or stellate-pubescent; bracts 5-10 mm. long, 

 bifid; pedicels densely hirsute to glabrous; calyx 4-6 mm. long, more or less hirsute 

 and with a few intermingled stellate hairs in some specimens, the lobes triangular- 

 ovate, acuminate; petals 10-15 mm. long, mauve-colored to rose-purple; carpels 

 2.5-3 mm. high, nearly as wide, reticulate on the angles, the back usually smooth; 

 beak stout, obtuse, somewhat reflexed, hispid-tipped.

 Ariz., June-Sept.; Wyo. and Ida., s. to Calif, and Mex. 



3. Kosteletzkya Presl Salt Marsh-mallow 

 About 30 species, mostly in tropical America and Africa. 



1. Kosteletzkya virginica (L.) Gray. Fig. 520. 



Branched perennial herb closely resembling Hibiscus, to about 15 dm. high, 

 rather roughly stellate-hirsute or -tomentose throughout, greenish or somewhat 

 cinereous; leaves gray-green, densely pubescent, the lower ones cordate-suborbicular 

 to -ovate and angulate or coarsely toothed, the upper and bracteal leaves mostly 

 lanceolate and without or with hastately divergent basal lobes; pedicels capillary 

 to coarse and short, frequently equaling or exceeding the bracteal leaves; flower- 

 ing calyx minutely puberulent to densely pubescent, 5-lobed, 8-13 mm. long, its 

 linear-subulate bracteoles 6-10 mm. long; petals 5, roseate, 3-4.5 cm. long, 2-3 

 cm. wide; column (including styles) 15-25 mm. long; fruit prominently 5-angled, 

 depressed; carpels copiously villous-hirsute with hairs 1.5-2 mm. long; seeds 

 smooth, one in each carpel. 



In brackish or nearly fresh marshes and along shores of lakes and ponds, and 

 in swamps, along coastal e. Tex., June-Oct.; from Fla. to Tex., n. to Va. and Del.; 

 also Cuba. 



Our plant is usually referred to var. althaefolia Chapm. \K. althaefolia (Chapm.) 

 Gray], characterized by having its stems and calyces densely pubescent. 



4. Hibiscus L. Rose-mallow 



Plants perennial or rarely annual, often shrubby; leaves merely crenate or den- 

 tate, or pedately cleft; flowers axillary, solitary, the petals 2 cm. long or more; 

 involucel usually present; fruit a loculicidal capsule, the carpels 5; seeds several in 

 each cell, essentially glabrous to long-hairy. 



About 300 species mainly in tropical and subtropical regions.
