678 Rydberg: Rocky Mountain flora 



Wheelerella circumscisssa Grant, Bull. So. Calif. Acad. Sci. 5: 



28. 1906. 



Piptocalyx Torr. of 1871 is antedated by Piptocalyx Oliver of 

 1870 and therefore Greeneocharis Giirke & Harms was proposed 

 instead of the former in the appendix to the Register of the Engler 

 & Prantl, Natiirlichen Pflanzenfamilien.* This name was prop- 

 erly published, although no binomials were used. There was 

 therefore no need of substituting another generic name Wheelerella 

 as was done by Grant. The fact that the etymology is not as 

 good as it might be does not at all invalidate Greeneocharis. Re- 

 luctantly the writer is forced to add another binomial to the 

 already too many names of this plant. 



Oreocarya spicata sp. nov. 



Perennial, with a taproot; stem solitary and simple, virgate, 

 hispid throughout ; basal leaves numerous, spatulate, 2-5 cm. 

 long, hispid on both sides ; the hairs usually with pustulate bases ; 

 stem-leaves linear-oblanceolate or linear, 4-9 cm. long, those of 

 the inflorescence many times longer than the short flower clusters ; 

 inflorescence elongated, spike-like ; calyx hispid, 4-5 mm. long, 

 lobes oblong-lanceolate, obtuse ; corolla 6 mm. long, 4 mm. 

 broad ; nutlets 4 mm. long, ovate in outline, scarcely keeled on 

 the back, white and shining, smooth on the back, margins merely 

 acute. 



This species is closely related to Oreocarya virgata, from which 

 it differs in the light-colored, smooth nutlets, the smaller corolla- 

 limbs, shorter and broader basal leaves. The nutlets in 0. virgata 

 are more acuminate, brown or brownish gray, with a more dis- 

 tinct ridge on the back, more or less transversely rugose and 

 tubercled on the back, and with sharper margins.

 stem, and on a few small branches ; calyx-lobes linear-filiform,
