16. KOSTELETZKYA Presl, Rel. Haenk. 2: 130. 1836. 



Plants herbaceous or suffrutescent, the pubescence chiefly of stellate hairs; 

 leaves often angulate or lobate ; flowers axillary or paniculate ; petals erect 

 or spreading; bractlets 7 to 10; capsule 5-angulate, the cells 1-seeded. 



Probably none of the species deserve to be classed as shrubs. 



Petals erect, convolute, 2 to 3.5 cm. long. 



Stems hispid 1. K. paniculata. 



Stems minutely stellate-pubescent. 



Capsule hispid ; leaves not lobed 2. K. malvaviscana. 



Capsule glabrate except on the angles ; leaves motly 3-lobed__3. K. thurberi. 

 Petals spreading, usually less than 2 cm. long. 



Pubescence of the stems chiefly of long simple hairs, very few, if any, small 

 stellate hairs present. 

 Leaves, at least the upper ones, 3 to 5-lobed nearly or quite to the base. 



4. K. coulteri. 

 Leaves, at least the upper ones, not lobed, the lower ones angulate or shal- 



lowly lobed 5. K. hastata. 



Pubescence of the stems of stellate hairs, these mostly very small. 



Upper leaves mostly or 3 or 5-parted 6. K. digitata. 



Upper leaves not lobed or merely hastate-lobed 7. K. sagittate.
