‘ Dodecatheon multiflorum sp. nov. 
Plant glabrous, perennial with a very short caudex and cluster 
of fibrous roots; leaves about 2 dm. long, sinuate-denticulate, ob- 
tusish, narrowly oblanceolate, tapering below into a short petiole ; 
Scape stout 3-4 dm. high; bracts linear-lanceolate, 1-2 cm. long ; 
flowers 10-20; the longer pedicels often over 1 dm. long; calyx- 
tube 5-6 mm. long, more or less turbinate at the base; lobes 
lanceolate, about 5 mm. long; corolla bluish violet, paler in the 
throat but without any markings ; lobes oblong, obtuse ; filament- 
tube obsolete ; anthers narrowly linear-lanceolate, acute, 7-8 mm. 
long; connective narrow, lance-subulate, with a longitudinal 
groove, but not rugose; capsule about 12 mm. long, cylindric- 
ovoid, septicidal. 
In habit this species resembles D. radicatum and D. paucifiorum, 
but differs in the stamens, which are almost without a filament- 
tube. In river valleys at an altitude of 2400-2700 m.
