478 MEMOIRS OF THE XEW YORK BOTANICAL GARDEN. 



Like M. rohmdifolia in habit, but with small blue petals scarcely 

 exceeding the sepals, which enlarge in fruit and become recurved- 

 spreading. Introduced in waste places. 



Montana : Concord, 1890, R. S. Williams. 



On page 262, before Viola Canadensis, insert : 



* Viola atriplicifolia Greene, Pittonia, 3: 38. 



Like V. venosa, but smaller, finely cinereous-puberulent, and the 

 leaf-blade 1-1.5 cm. long and sinuately 3-7-toothed. Mr. Blankin- 

 ship's specimens are in fruit from the cleistogamous flowers, the 

 pedicels are erect, 1-2 cm. long, and pods about 4 mm. long each con- 

 taining two large yellowish seeds. 



Yellowstone Park : 1893 Burglehaus (according to Greene, 

 type) ; Lower Falls and Upper Gevser Basin, 1899, J- ^^- Blankin- 

 ship. 



On page 265, before LIXACEAE, insert: 



* Geranium thermale. 



Perennial or biennial : stems several, diffuse, much branched, 

 1-1.5 dm. long, finel}" pubescent: lower leaves with slender petioles, 

 3-4 cm. long; blade round-reniform, puberulent on the veins, 

 1.5-2 cm. in diameter, truncate at the base, 5-cleft to beyond 

 the middle ; lobes cuneate, the terminal 3-toothed at the apex, the 

 lateral 2— 3-toothed or entire ; upper stem-leaves similar, but smaller 

 and only 3-cleft ; pedicels axillary, generally shorter than the petioles, 

 finely pubescent; sepals 3 or, in fruit, 5 mm. long, broadly ovate, 

 pubescent, ending in a very short bristle-tip : petals purplish rose- 

 color, slightly exceeding the sepals ; carpels puberulent and hirsute, 

 not wrinkled, about 3 mm. long ; beak 7-8 mm. long, rather long- 

 pointed ; seeds minuteh" pitted. 



In general it is apparently nearest related to G. Carolinianiim 

 and G. Bicknellii, but much smaller, with smaller less-divided leaves, 

 shorter bristle-tips on the sepals, and is, so far as can be judged from 

 the specimens, a perennial or at least a biennial. It also resembles 

 the next in the size and form of the leaves, but differs in the pres- 

 ence of the bristle-tips and the pitted seeds. 



Montana : Lo-Lo Hot Springs, 1898, Williams cf- Griffith. • 



* Geranium pusillum L. Sp. PI. Ed. 2, 957 [111. Fl. 2: 343; Syn. 



Fl. i': 361]. 



A species resembling G. Caroliniaiium in habit, but with smaller 

 leaves and flowers, only 5 stamens, and smooth seeds. The lobes of
