126 GATES: REVISION OF GENUS POLYGONATUM 
in C. Polygonatum. The exact features of this plant can only be 
determined by examination of the original specimen in the 
Desfontaine herbarium, in Paris. 
’ 8. Polygonatum cobrensis (Wooton & Standley) comb. nov. 
Salomonia cobrensis Wooton & Standley, Contrib. U. S. Nat. 
Herb. 16: 113. 1913. 
New Mexico. 
Through the kindness of Mr. William R. Maxon of the National 
Herbarium I have been able to examine the type specimen, which 
came from Copper Mines, Santa Rita, New Mexico. The follow- 
ing specimen (PLATE 6, B), in the herbarium of the Missouri 
Botanical Garden, came from a neighboring locality and shows 
still better the features of this species: Pinos Altos Mountains, 
New Mexico, E. L. Greene, May 21, 1880. Dr. Greene referred 
this specimen to the European P. vulgare Desf. which it evidently 
resembles, though I have seen no specimens of the latter which 
approach it very closely. A critical comparison should be made 
with European specimens. The species most resembles P. biflorum 
hebetifolium. : : 
9g. POLYGONATUM ELLIPTICUM Farwell 
Polygonatum ellipticum Farwell, Bull. Torrey Club 42: 255. pl. 
16, B. 1915. 
This species was based on material collected by its author at 
Rochester, Michigan, in June, 1914. Since I have seen no speci- 
mens I am unable to judge of its status.
