480 PROCEEDINGS OP THE AMERICAN ACADEMY 



surrounded by a tinge of pale yellow ; inner petals auriculate above 

 the very short claw, the auricles fleshy and subsaccate and the two 

 scales subglobose-inflated : filaments purple, very slender and atten- 

 uate, about twice longer than the rather short brownish anthers 

 (2 lines long) : style narrowly clavate, shorter than or about equalling 

 the stamens, the triaugular-cupulate stigma very shortly 3-lobed. — 

 Near Ashland, Jackson County, Oregon {L. F. Henderson, At^yW, 1887), 

 and at Grant's Pass, Josephine County {T. Howell, the same month). 



Erythronium citrinum. Resembling the last: flowers rather 

 smaller, the petals lemon-color, with a broad orange-colored spot near 

 the base and the tips becoming tinged with pink, the inner auriculate ; 

 auricles scale-bearing or calliferous on the inner side and the broad 

 median pair of scales rather thin : filaments, especially the inner ones, 

 somewhat stouter, yellowish or white, as also the anthers. — In the 

 Deer Creek Mountains, Josephine County, Oregon ( T. Howell, April, 

 1887). The specimens are 3-flowered. 



Erythronium Howellii. Resembling the preceding : leaves 

 mottled (?) : petals pale pink or becoming so, with a deep orange- 

 colored spot toward the base, the inner narrowed downward, without 

 auricles or scales : stamens white, the filaments very slender. — At 

 Waldo, Josephine County, Oregon (^T. Howell, April, 1887). These 

 species of southern Oregon form a closely related group, characterized 

 by the short style and very shortly lobed cupulate stigma, and dis- 

 tinguished from each other by the color of the flowers and by the 

 character or absence of the appendages of the inner petals. It is upon 

 such characters that we must depend to distinguish the members of 

 the confused E. grandiflorum group, which have a longer style and 

 linear (at length recurved) stigmas. Unfortunately it is difficult to 

 recognize the differences in any but fresh or recently dried specimens. 

 It is probable that investigation will prove E. grandiflorum to be dis- 

 tinguishable from the species prevalent in the Rocky Mountains, as 

 well as from the E. giganteiim of the lower Columbia, and the 

 E. revolutum of the coast. The original of Pursh's E. grandiflorum 

 (1814) was collected on the Clearwater, and the only specimens from 

 that region in herb. Gray (from Spalding) are too poor for examina- 

 tion. E. revolutum (1810) was founded upon plants collected by 

 INIenzies near the coast, possibly in California. When the characters 

 of these species can be determined with satisfactory probability others 

 may follow. 



JuNCUS CoNGDONi. GraminifoUus : annual, with several low and 

 mostly simple stems (2 to 4 inches high), leafy at base : leaves nearly
