or obovate-lanceolate. Petals white, obovate or spatulate, often short-clawed. Stamens 
5, opposite the sepals. Ovary 1/4 inferior, 2-celled; styles 2; placentae axial. Follicle- 
beaks 2, divergent. Seeds shining. (Honor of a Dr. Boykin, of Georgia.) 
A. Petals white. 
B. Stipules none or mere bristles. W.C. (J. majus intermedium. ) 
B. major Gray 
BB. Stipules wider, scarious or foliaceous. W.-C. (T. vancouverense; T. elatum.) 
B. occidentalis T. & G. 
AA. Petals dark-purple. E. B. heucheriformis Nels. 
SULLIVANTIA 
Perennial, acaulescent, slender; stems scape-like. Leaves alternate, mostly basal, 
only | on the stem; blades kidney-shaped to orbicular, shallow-lobed, often coarsely 
toothed, cordate at base; petiole long. Flowers in panicled cymes. Calyx-tube cam- 
panulate; segments 5, erect, shorter than the tube. Corolla white or whitish, regu- 
lar. Petals persistent, clawed. Stamens 5. Ovary fully 1% inferior; carpels united to 
the beaks. Follicles erect, included in the calyx-tube.. Seed winged. (Honor of W. S. 
Sullivant, an American bryologist.) W. E. 
S. oregana Wats. 
HEMIEVA 
Perennials, glandular-puberulent. Basal leaves ternately divided and crenate, or cre- 
nate only; stem-leaves with stipules. Flowers in a panicle. Calyx-tube campanulate or 
urn-shaped; segments 5, triangular-lanceolate. Petals obovate, clawed. Stamens 5, op- 
posite the sepals, erect. Ovary |/2—2/3 inferior, 2-celled; placentae axial; styles 
distinct. (Possibly Gk. hemi—!/,, L. aevum—an age; in reference to its half-perennial 
form, thru budding in the leaf-axils. ) 
A. Petals white, with short claw; ovary '/% inferior. C. E. 
H. ranunculifolia Raf. 
AA. Petals violet, with long claw; ovary 2/3 inferior. E. 
H. violacea Wheel. 
SAXIFRAGA SAXIFRAGE 
Herbs but sometimes shrubby, chiefly perennial. Leaves mostly alternate (so in 
ours), simple; petioles usually sheathing at base. Flowers small, in cymes or corymbs 
or racemes or panicles. Sepals 5. Petals on the calyx-tube when there is one, entire or 
2-toothed. Stamens 10, with or below the petals. Carpels usually 2, rarely 3—6; 
ovary of as many cells; fruit with as many beaks. (L. saxum=rock, frangere—to break; 
because many species grow in rock-clefts. ) 
A. Leaves noi all basal. 
B. Leaves entire; petals not always entirely white; plants with perennial leafy shoots. 
C. Leaves no: spine-tipped, obtuse. 
D. Filaments clavate; petals white, 4—5.5 mm. long. C. (S. ledifolia.) 
S. tolmiei T. & G. 
DD. Filaments subulate; petals light yellow, 6—7 mm. long. W. 
S. serpyllifolia Pursh 
CC. Leaves spine-tipped, acute. W. E. (S. austromontana; S. scherleroides 
for our region. ) S. bronchialis L.
