size of bulb it is related to Z. paniculatus, but it has flowers much larger and all 
the floral organs differently shaped. It is probably the largest species of Zyga- 
denus known. It is probable that there is no Z. paniculatus on the western slope 
of the Sierra Nevada. 
“ Silene deflexa, n. sp.—Stems several from a creeping root- 
stock, about 24" high, erect, glandular-puberulent especially above: 
radical leaves spatulate, 1-2°" long including the margined 
petioles, rather thick in texture, obtuse; cauline leaves 3-4 pairs, 
the uppermost very small, not more than 3™™, the lowest oblan- 
ceolate to oblong, obtuse, 2°" long, connate-clasping and nodose 
at base: flowers solitary in the lower leaf-axils, pedicels erect and 
close to stem, flowers curved-deflexed in anthesis, erect in fruit; 
terminal flowers few, cymose, pedicels capillary, 7-12™™ long, 
generally shorter than the flowers; calyx narrowly cylindrical in 
flower, enlarging and breaking apart with the expanding capsule, 
ro-ribbed, 9™™ long, divisions rounded at apex, oblong, some- 
times uneven, membranously margined, 1.5™™ long; petals with 
the claws united tc the stamens and the stipe of the ovary at base, 
woolly, gradually enlarging to the blade, not auricled, blade 4-cleft 
into linear lobes, the two middle 2™™ long, o.5™™ wide, the two 
lateral narrower and shorter, appendages oblong, reaching the base 
of divisions, retuse with one side pointed; stamens and styles appar- 
ently not surpassing the petals, the latter three and the upper thick 
part of the ovary splitting into three valves, lower part of ovary 
thin cylindrical, all together 4™™ long; stipe 1™™ long and almost 
as thick: seeds suborbicular, brown, strophiolate. 
Type collected in the Hudsonian Zone above the nies Canyon Creek, 
Trinity County, California, by Vernon Baily, August 25, 
It is related to S. Lemmoni, but differs in the foliage, eS shorter filaments 
and styles, the close inflorescence, and the differently shaped floral organs. It 
really resembles that species only in having the flowers pendent and the 
blades of the corolla with four divisions. 
’ Silene lacustris, n. sp.—Cespitose from+ creeping rootstocks, 
slender, erect, 1-1.5 high, glandular-puberulent throughout 
especially the inflorescence, flowering from the lowest axils: radical 
leaves narrowly oblanceolate, acute or obtuse, tapering to a long 
margined petiole, all together 2°™ long; cauline leaves 2-3 pairs, 
linear, obtuse, connate-clasping at base, 1-2°™ long, 1-2™™ wide:
