108 WooTON AND Standley: Plants from New Mexico 



pitted or only inconspicuously veined, carpels ending above in 

 proaiincnt divaricate cusps, which are about 2 mm. long ; seeds 

 brown, densely and finely stellate-pubescent. 



Type collected at Mangas Springs, Grant Co., New Mexico, 

 Sept. 24, 1903, at an altitude of about 1 465 m., Metcalfe ygi (in 

 part at least), growing on a western hillside. This plant is easily 

 distinguished from 5. Fendleri, which it most resembles, by its 

 broader, obtuse, less incised leaves, more prominent cuspidate car- 

 pels, and the smooth, not pitted, inner surfaces of the carpels. 



Sphaeralcea tripartita sp. nov. 



Stems finely stellate-pubescent throughout, densely so above; 

 leaf-blades 3 -parted, the lower ones almost to the base, the upper 

 ones not quite so deeply, the lobes of the blade entire or the 

 middle one again 3-lobed and the lateral ones 2- or 3-Iobed, not 

 crenate, the lobes when entire oblong, the lateral ones smaller 



■ and 70 mm 



thin, bright green on both surfaces, finely stellate-pubescent above 

 and more densely so below, the pubescence white ; the uppermost 

 leaves almost or quite entire and oblong-lanceolate, petioles rather 

 stout, almost one third as long as the blades ; inflorescence nar- 

 rowly subpaniculate, rather loose ; flowers on short, stout, densely 

 stellate-pubescent pedicels, each subtended by 2 or 3 thick, filiform 

 bracts, which are about one half as long as the calyx ; calyx-lobes 

 triangular-lanceolate, thick, acute, densely stellate-pubescent ; 

 corolla about 9 mm. long, 2 or 3 times as long as the calyx, the 

 petals pink, obovate, rounded above ; fruit 5 mm. broad and 4 mm. 

 high, with 5 to 10 carpels, which are densely pubescent on their 

 outer surfaces and more or less prominently pitted near the base 

 of their inner surfaces, i- or 2-seeded, pointed but not cuspidate, 

 equaled or exceeded in length by the sepals ; seeds dark brown, 

 finely and very sparingly stellate-pubescent. 



Type collected at Kingston, Sierra Co., New Mexico, growing 

 in dry gravel, July 10, 1904, Metcalfe iioj ; altitude about 2030 

 m. Nearest 5, Fendleri and 5. leiocarpa perhaps, but differing 

 from both in the peculiar form of the leaves, whose lobes are 

 mostly entire. There is no complete plant in the collection but 

 only some of the upper branches. The plant is, no doubt, a per- 

 ennial several feet high. 



Sphaeralcea laxa sp. nov. 



Stems erect, slender, much branched, about 5 dm, high, with 

 rather dense and fine white stellate pubescence throughout, the
