§ 6. Caudex above the ground scarcely any : stem (scape) annual, mostly leaf-

 with slender claios, often unequal : filaments filiform : seeds longitudinally 

 striate. — Arabidia, Tausch.

Greenland and Labrador! Also in Canada according to Pursh : but this 

 is doubtful. — Peduncles filiform, ascending, a little hairy. Petals white, 

 with 2 yellowish spots near the base. Seeds marked with indistinct elevated 

 toothed strias. 



26. S. foliolosa (R. Br.) : radical leaves cuneiform, slightly toothed ; 

 scapes divided ; the branches 1-flowered at the summit, and at their base

Arctic Islands, Capt. Parry! Sfc. — Seems to be distinct from S. stellaris 

 (which has not been found in Melville Island) by the dense clusters of little 

 leaves on the scapes, the flowers very few (or none), the obovate calyx, 

 and particularly by the lamina of the equal petals being cordate at the 

 base. jR. Br. 



27. iS. leucanthemifolia (Lapeyr. ?): more or less viscidly pubescent; 

 /' leaves radical, oblong-cuneiform, attenuate into a petiole, incisely toothed ; 



scape corymbose or panicled, many-flowered, the pedicels capillary; calyx 

 free, reflexed ; petals spreading, unequal, unguiculate ; the three larger ones 

 cordate-lanceolate or abrupt at the base, marked with two yellow spots ; the 

 two smaller lanceolate, attenuate at the base, not spotted; seeds marked 

 with regular crested strias. 



a. villous with viscous hairs; leaves spatulate, attenuate into a long 

 margined petiole, coarsely and very sharply toothed ; scape more or less 

 leafy; paniclfe very much branched, diffuse. — S. leucanthemifolia, Michx.!

On the mountains of North Carolina ! and Georgia (a.) June-Sept. — 

 P. Rocky Mountains, Oregon ! and N. W. Coast ! y. Norfolk Sound, Esch- 

 scholtz ! J. Sitcha, Bongard ! Norfolk Sound, Eschscholtz ! — The plant of 

 the mountains of N. Carolina is from 12-20 inches high, with a large very 

 diffuse panicle, continuing to flower through the summer : the leaves are 

 deeply and pectinately toothed. The Oregon plant we believe to be the 

 same species, but the leaves are less deeply toothed and the panicle is more 

 corymbose in all the specimens we have seen. It passes by several grada- 

 tions into our var. 6. which is scarcely different from S. foliolosa, R. Br. ; a 

 species which will perhaps prove to be an arctic variety of the present, rather
