136 SAXIFRAGE FAMILY. 



* Flowers very small : stamens and styles protruding. 



H. Americana, COMMON A. : the only one N. and E. of Penn., has 

 scapes and loose panicle (2 -3 high) clammy-glandular and often hairy, 

 leaves with rounded lobes, and greenish flowers in early summer. 



H. villbsa, from Maryland and Kentucky S. along the upper country, is 

 lower, beset with soft often rusty hairs, has deeper-lobcd leaves, and very small 

 white or whitish flowers, later in summer. 



# # Flowers larger (the calyx fully ' long), in a narrower panicle, greenish, with 



fit (linens little if at all protruding : leaves round and slightly 5- 9-lobed. 



H. hispida. Mountains of Virginia and N. W. Tall (scape 2 -4 

 hi;h), usually with spreading hairs; stamens a little protruding. 



H. pub^SCenS. From S. Penn. S. Scapes (l-3 high) and petioles 

 roughish-glandular rather than pubescent ; stamens shorter than the lobes of 

 the calyx. 



9. BOYKINIA. (Named for the late Dr. Boykin, of Georgia.) ^ 



B. aconitifblia, occurs only along the Alleghanies from Virginia S. : 

 stem clammy-glandular, bearing 3 or 4 alternate palmately 5 - 7-cleft and cut 

 leaves and a cyme of rather small white flowers, in summer. There is one very 

 like it in Oregon and California. 



10. SAXIFRAGA, SAXIFRAGE. (Latin name, means rock-breaker ; 

 many species rooting in the clefts of rocks.) Besides the following, there are 

 a number of rare or local wild species. 



# Wild species, with leaves all clustered at the perennial root, the naked scape 



clammy above and bearinq many small flowers in a panicle or cyme, the two 

 ovaries united barely at the base, making at length a pair of nearly separate 

 divergent ]>ods. 



S. Virginiensis, KAKLY S. On rocks and moist banks; with obovate 



or wedgc-spatulate thickish more or less toothed leaves in an open cluster, scape 



/-// 3' -9' high, bearing in early spring white flowers in a dense cluster, which 



at length opens into a loose panicled cyme ; calyx not half the length of the 



petals ; pods turning purple. 



S. Pennsylvanica, SWAMP S. In low wet ground N. ; with lance- 

 oblong or oblanceolate obtuse leaves (4' -8' long) obscurely toothed and nar- 

 rowed into a very short broad petiole, scape l-2 high, bearing small 

 greenish flowers in an oblong cluster, opening with age into a looser panicle (in 

 spring) ; the rcflexed lobes of the calyx as long as the lance-linear petals. 



flowers (in summer) ; with reflexcd sepals as long as the oval petals, and club- 

 shaped filaments. 



* * Exotic species, cult, for ornament : leaves all clustered at the perennial root : 

 ovaries 2, or sometimes 3-4, almost separate, becoming as many nearly dis- 

 tinct pods. 



S. crassifblia, THICK-LEAVED S. Cult, from Siberia, very smooth, with 

 fleshy and creeping or prostrate rootstocks, sending up thick roundish-obovate 

 nearly evergreen leaves, G' - 9' long, and si-apes bearing an ample at first com- 

 pact cyme of large bright rose-colored flowers, in early spring. 



S. sarmentbsa, BEEFSTEAK S., also called STRAWBERRY GERANIUM. 

 Cult, from China and Japan as a house-plant, not quite hardy N., rather hairv, 

 with rounded heart-shaped or kidney-shaped and doubly toothed leaves of tU->liy 

 texture, purple underneath, green-veined or mottled with white al>ove, on shaggy 

 petioles, from their axils sending oil' slender strawberry-like runners, by which 

 the plant is multiplied, and scapes bearing a light very open panicle of irregular 

 lloun-s, with 3 of the petals small rose-pink and yellow-spotted, and 2 mch 

 longer and nearly white ones lanceolate and hanging.
