Talintjm pyg^^um (Gray, in Rep. Exped. Bryan, ined. & in 

 Sill. Jour. 33, p. 407) : foliis linearibus scapisque unifloris (nunc 

 2 - 3-floris) 1 - 2-pollicaribus e radice crasso confertis ; sepalis orbicu- 

 laris glanduloso-dentatis ; petalis roseis purpureisve ; staminibus 6 ; 

 6tigmatibus 3-5. — Rocky Mountains, H. Engelmann, Dr. Parry, &c. ; 

 Cascade Mountains, "Washington Terr., alt. 7,500, Dr. Lyall ; and now 

 collected in the Sierra Nevada, California, by Bolander. The thick 

 caudex or root is rather fusiform in most specimens, in Bolander' s it is 

 napiform. Ovules numerous. Seeds as in the genus. 



Sidalcea vitifolia : hirsuto-pubescens ; caule valido elato ra- 

 moso folioso ; foliis cordato-quinquelobis, lobis brevibus crenato-dentatis 

 subincisis ; spicis brevibus capitulisve densifloris brevipedunculatis 

 subcorymbosis ; calycis nudi lobis deltoideis acutatis ; petalis albis 

 obcordatis ; phalangibus indistinctis ; coccis muticis Irevibus. — Bear 

 Harbor, Mendocino Co., Bolander. Plant " from 3 to 6 feet high, 

 in tufts," the upper part or branches leafy ; the branchlets terminated 

 by short and dense spikes or heads of one or two inches in length. 

 Stipules subulate, caducous. Leaves 2-4 inches in diameter, beset 

 especially beneath and on the petioles, as also the branches, with a 

 short and roughish stellate pubescence. Pedicels extremely short, 

 subtended by a filiform bract, which is often 2-cleft or toothed at the 

 apex and deciduous : bractlets none." Calyx very slightly or sparsely 

 hirsute, 3-4 lines long, cleft to the middle. Corolla G lines long, 

 apparently white ; the petals rather narrow. Stamens of the exterior 

 series closely approximate to the inner, consisting of 10 narrow and 

 2-cleft biantheriferous filaments, i. e. each fork bearing a single anther ; 

 the inner set of about as many anthers, on mostly uncombined filaments. 

 Branches of the style and carpels 9 or 10, the latter reniform, torn open 

 on the ventral face as they separate from the axis. This new species, 

 so unlike the rest of the genus in appearance, is closely related to 



Sidalcea malachroides (Malva malachroides, Hook. & Arn.) ; 

 hispida, gracilior ; foliis cordato-rotundis sublobatis crenato-incisis ; 

 calyce setoso-hispidissimo 2 - 3-bracteolato (bracteolis setaceis deci- 

 duis), lobis triangulari-lanceolatis : caet. fere praecedentis. — The two 

 series of stamens, the exterior of 20 in pairs, I had not before detected 

 in this rare plant. The fruit not yet seen. In a fragment of a fertile 

 plant collected by Dr. Andrews the column is truncate and without a 

 single anther in all the flowers ; while in Douglas and Coulter's speci- 

 mens, with good anthers, the ovules are apparently good. The anthers,
