Sphaeralcea grandiflora sp. nov. 



A meter or two hi^^h ; stem glabrous below, stellate above ; 

 petioles of the lower leaves 1—2 dm. long ; blades cordate or 

 reniform in outline, maple-like, 9—15 cm. wide, deeply 5— 7-lobed ; 

 lobes lanceolate or triangular, coarsely toothed with triangular 

 teeth ; flowers in small axillary clusters, but at the end of the 

 stem the subtending leaves become diminished and the inflorescence 

 resembles a congested panicle ; pedicels and calyx densely hirsute- 

 pubescent with long stellate hairs, the branches of which are 1—2 

 mm. long ; bractlets lanceolate, about half as long as the tri- 

 angular-ovate, acute or somewhat acuminate sepals ; petals pink- 

 ish, 3 cm. or more long ; fruit spherical, and deeply retuse at the 

 apex ; carpels membranous, smooth on the sides and bristly on 

 the back, rounded at the apex ; seeds reniform, brown, muricate. 



A close ally of 6". riviilaris, but differs in the larger flowers, 

 the broader bractlets, the long hairs of the calyx, the usually 

 blunter leaves and more rounded carpels. It grows at an altitude 

 of 2,200-2,800 m.

Touterea laciniata sp. nov. 



Biennial or short-lived perennial ; stems 3-4 dm. high, white, 

 puberulent, strict, in age branched ; leaves narrowly lanceolate in 

 outline, 5— 10 cm. long, deeply pinnatifid to near the midrib ; 

 sinuses rounded or nearly semi-rhombic ; lobes oblong to lance- 

 olate, obtuse : flowers usually bracted by 1-2 laciniate bracts ; 

 sepals about i cm. long, lanceolate with a subulate tip, soon 

 reflexed ; petals golden yellow i 5-20 mm. long, short-clawed ; 

 blades oblanceolate, acute ; staminodia similar and imitating 

 another set of petals ; filaments nearly filiform, 3/^ as long as the 

 petals. 



This species is closely related to T. spcciosa, but differs in the 

 deeply dissected leaves and more slender stem. In general habit 

 it resembles somewhat T. miiltiflora, for which it has been mis- 

 taken ; but that species has broader, obtuse petals, more dilated 

 filaments, and more diverging branches. T. laciniata grows on 

 dry hillsides at an altitude of 1,500-2,200 m.
