Anogra Nuttallii, n. comb. — Oenothera albicaidis Nutt. Fras. 

 Cat., name only; T. & G, Fl. N. A. i : 495 5 ^^t Pursh, Fl. Am. 

 Sept. 733; 0, Nuttallii Sweet, Hort. Brit. Ed. 2: 199. — Perennial 

 from woody horizontal rootstocks with short vertical caudicesor 

 crowns: stems one to several from the crown, erect, 5-10^™ high, 

 freely branched above, the somewhat shreddy bark white and 

 glistening; branchlets slender, widely divaricate: leaves very 

 numerous, somewhat fascicled at the axis, softly and minutely 

 puberulent on the lower surface, broadly linear, acute at apex, 

 tapering gradually to the nearly sessile base, margin entire or 

 merely denticulate; the primary ones of the fascicles 4-10 

 long, 5-8™™ broad; the secondary ones similar but quite small: 

 flowers in the crowded terminal axils of the branches, some- 

 what drooping in bud: calyx glandular-puberulent on the tube; 

 calyx-lobes narrowly lanceolate, 2-3 ^°* long, about as long as 

 the tube, scarcely puberulent, the tips free: petals white, broadly 

 obovate, entire or denticulate at the broad apex, nearly as long 

 as the reflexed calyx-lobes: anthers linear, 15^°^ long, as long 

 as the filament: stigmas exserted, linear, about 10'""' long: 

 mature capsule cylindrical, about 3 *^"^ long, pale, minutely puber- 

 ulent except on the rather broad whitish sutures, not contorted: 

 seeds narrowly ovate, light green, copiously speckled with 

 purple, indistinctly striate under a lens, about 2 ""^ long. 



I have long intended to give a nanic to this perfectly vaUd species. In 

 fact I have distributed some specimens under the herbarium name Anogra 

 arenaria. A more careful study of the synonomy convinces me now that 

 the above name is tenable. Oenothera albicauHs Nutt. never was a synonym 

 of O. pallida Lindl. Bot. Reg. 14://. 1142. It was evidently the purpose of 

 Sweet to distinguish this species ]of Nuttall from Pursh's species of the same 

 name, as it was also of Spach in his Baumannia Nuttalliana (Hist, Veg. 

 4: 352) and Anogra Nuttalliana (Nouv. Ann. Mus. Par. 4 : 339). 



This species is very common on sandy plains and banks from Nebraska 

 to Utah. It is at once distinguishable from Anogra pallida by the pubescent 

 leaves, inflorescence, and capsules; the larger flowers (resembling those of 

 A, albicaidis Pursh rather than those of A. pallida), and the larger straight 

 capsules and characteristic seeds. 



Lavauxia Howardi (Jones), n. comb. — Oenothera Hozvardi 

 Jones, Zoe 3: 301. — For some reason this species has been com- 

 pletely ignored by recent writers on the allies of Oenothera, as
