really far different from that species. 1 When a growing specimen becomes mature 

 the ends of the branches curve inward, forming a dense mass somewhat resembling 

 a bird's-nest, a peculiarity which, in the held, forms a good diagnostic character, 

 and to which the new specific name refers. 

 Specimens were collected in Cottonwood Canon, Panamint Mountains (No. 963). 



Eriogonum nivale Canby sp. nov. 



Plant perennial, cespitoso, densely white-tomentose throughout above the ground; 

 branches several from the caudex, short and stout, thickly covered with the remains 

 of former leaves, the present ones tufted at the ends of the branches, from which 

 spring the usually solitary, naked peduncles 2.5 to 8 cm. high; involucre solitary, 

 turbinate, about 3 mm. long, with 6 to 8 rounded teeth ; leaves very small, 4 to 6 mm. 

 long, ovate, tapering into a short petiole; flowers large for the size of the plant, 3 

 to 4 mm. long; perianth bright rose-color when young, becoming paler with age, the 

 divisions glabrous and of aboutequal length, each having a prominent much darker 

 midveiu, the outer ones rounded oval, the inner ones oblong or oblanceolate, all ob- 

 tuse and glabrous. 



Type specimen in the United States National Herbarium, No. 1657 of the Death Val- 

 ley Expedition, collected August 20, 1891, at timber-line on a divide northwest of 

 Whitney Meadows, Sierra Nevada, Tulare County, California, by Frederick V. 

 Coville. 



The species stands near E. ovalifolitim and E. kennedyi. 



Eriogonum nudum Benth. Trans. Linn. Soc. xvii. 413 (1837) — Dongl. MS. Type 

 locality, "plains of the Multoonah." 



In Tehachapi Canon (No, 1131) and near Whitney Meadows (No. 1645). Determined 

 by W. M. Canby. [The former of these two numbers presents an unusual branching 

 of the umbel.— w. M. c] 



Eriogonum nudum pauciflorum Wats. Proc. Amer. Acad. xii. 264 (1877). Type 

 locality not given. 



Valley of the South Fork of Kern River (No. 1031). Determined by W. M. Canby. 

 [This plant is as large as E. grande Greene, and intergrades with it. — w. M. C] 



Eriogonum ovalifolium Nutt. Journ. Acad. Phila. vii. 50 (1834). Type locality, 

 "sources of the Missouri." 

 Wood Canon, Grapevine Mountains (No. 1762). Determined by W. M. Canby. 



Eriogonum parryi Gray, Proc. Amer. Acad. x. 77(1874). Type locality, "South- 

 ern Utah." 



Near Keeler (No. 869), and in the Grapevine Mountains, Nevada (No. 979). In 

 one specimen the reniform leaves attain a breadth of 4.5 em. 



Eriogonum plumatella Dur. & Hilg. PI. Heerm. 45 (1855). Type locality, "Posa 

 Creek," Kern County, California. 



By some singular mistake the name of this plant was very early transferred to a 

 totally different annual species confined to the interior desert region. The true E. 

 plumatella, the incomplete specimens of which were excellently figured, 2 is shown 

 by an examination of the original plant of Durand and Tlilgard, kindly loaned by 

 Mr. J. H. Kedfield of the Philadelphia Academy, to bo the same as that afterward 

 described and since known as E. palmeri. The two species have almost no resem- 

 blance except in their calyces. E. plumatella is a perennial with tall, zigzag stems, 

 scattered, abruptly divaricate branches, and oblanceolate leaves at the forks; while 

 the other, which has been named above E. nidularitim, is an annual with a dense 

 mass of ascending branches, and its leaves all radical and orbicular. 



Specimens of Erfoyonum plumatella were seen in Walker Pass.
