are sparsely and coarsely pubescent though not glandular; and the leaves are entirely 

 too broad to be called less than elliptic-lanceolate. The specimen shows only three 

 upper leaves. Specimens collected both by Standley and by Snow show the lower 

 leaves as elliptic. 



The writers have heard fairly reliable reports of the occurrence of another species of 

 Cypripedium in the mountains east of Santa Fe, The plant has been observed in 

 Santa Fe Canyon and in the mountains east of the Pecos. It is said to have a white 

 lip splotched with purple. We have been unable to procure material of it, and it is 

 possible that the plant belongs to some other genus.

A low herb, 10 to 15 cm. liigh, with a single showy rose-colored nodding flower at the

 also in Europe and Asia.

3. CORALLORHIZA R. Br. Coral root. 



Stems stout, simple, erect, from a cluster of coral-like rootstocks (whence the generic 

 name); leaves represented only by membranous sheaths; whole plant without green 

 coloring matter; flowers purplish, the white lip usually spotted with purple. 



Our species are found only in moist, shaded, usually cool woods, where they are 

 very striking because of the absence of green coloring. 



KEY TO THE SPECIES.

 Range: Alaska and British America to Florida and California. 

 New Mexico: Winsor Creek; Harveys Upper Ranch; Tunitcha Mountains; Chama; 

 East Canyon. In woods, in the Canadian Zone.

 Type locality: Veta Mountains, Colorado.

Reported from the vicinity of Pecos by Professor Cockerell, the specimens identi- 

 fied by Rydberg. 



Metcalfe's 1513 from the Black Range seems to represent another and possibly 

 undescribed species. Our material is entirely insufficient for diagnosis. 



4. PERAMIITM Salisb. Rattlesnake plantain. 



Low plants, 10 to 25 cm. liigh, with basal rosettes of somewhat fleshy, often varie- 

 gated, ovate or oblong-ovate leaves; flowers on a stout scape, this glandular-viscid,
