Saxifraga nidifica Greene, Erythea, i: 222. 1893. 



This rare Saxifraga has lately been sent me by Mr. E. P. Shel- 

 don. The specimens are from Spokane, Washington, altitude 

 1,000-2,000 feet and were collected by J. H. Sandberg and J. B. 

 Leiberg in May, 1893. Saxifraga nivalis (no. 1819) of Mr. Co- 

 ville's Death Valley report, apparently belongs here, as does also 

 Torrey's 155, collected in the Yosemite Valley and Mountains,. 

 California, in 1865. 



Saxifraga plantaginea n. sp. 



Perennial by a thick rootstock, stout, scapose, glandular-pilose;, 

 leaves elliptic or elliptic-spatulate, 6-10 cm. long, obtuse, undulate 

 or distantly and shallowly toothed, leathery, ciliate, 5-7-ribbed,. 

 narrowed into a winged petiole, which is usually much shorter than 

 the blade ; scape erect, 2-4 dm. tall, sparingly branched near the 

 top, the branches subtended by elliptic bracts ; flowers greenish, 

 in dense cymules; calyx flat, its segments ovate, 3.5 mm. long,, 

 obtuse, 3-nerved, longer than the tube ; petals suborbicular-oblong 

 or some inclined to be broadly spatulate, 2-2.5 i^ini- long, green- 

 ish, shorter than the calyx-segments, obtuse, marked with a mid- 

 nerve and several branches, narrowed into a broad claw; filaments 

 converging, subulate, shorter than the petals ; ovaries immersed 

 in a lobed disk ; fruit not seen. 



Spokane, Washington, at 600-1,000 meters altitude; collected 

 by J. B. Leiberg and J. H, Sandberg, in May, 1893. Comm.uni- 

 cated by Mr. E. P. Sheldon. 



A fine species with leaves strongly resembling those of some 

 of the broader-leaved Plantagos. The plant is very different 

 from anything heretofore known in the genus Saxifraga. It 

 is related to 5. integrifoiia. The broad greenish petals, which are 

 exceeded by the calyx, serve to separate the . species from all its 

 relatives. 



Saxifraga Sierrae (Coville). 



Saxifraga integrifoiia Sierrae Coville, Proc. Biol. Soc. Wash. 7: 

 78. 1892. 



Saxifraga OreganaY{Q\VQ}^,^xy\\\td.,'>>'- 34. 1895. 



As Mr. Howell points out, Saxifraga integrifoiia has been a 

 composite species. Mr. Coville dwells on the differences in the 

 leaves of Saxifraga Sierrae and vS. integrifoiia; these differences are 

 much more marked in specimens collected later by Mr. Howell,
