of Pyrola and the foliage of Galan It seems to be more nearly related to the 

 latter than to the former. Until, however, the flowers of this plant (of which only 

 a single specimen, in fruit, is extant) are obtained, it will be impossible to 

 determine its place in the system with certainty. 



Of the five genera and seven species that constitute the suborder Monotropese, 

 so far as at present known, four of the genera and five of the species are peculiar 

 to North America. 



Several of the species have a very wide range, both in latitude and longitude. 

 Monotropa uniflora* occurs from Canada to Florida, and from the Atlantic to the 

 Pacific coasts. On the western side of the continent it seems to be confined to 

 Oregon. Hypopithys lanuginosa is spread almost as widely. H. mul iflora, f it 

 be really indigenous to North America, has not been found within the limits of 

 the United States. The rare Schweinitzia is a somewhat southern genus, never 

 having been observed in a higher latitude than Baltimore ; while Pterospora is 

 exclusively northern, the State of New York being its limit to the south, although 

 it has been found as far west as the Cascade Mountains of Oregon. Sarcodes is 

 wholly a Californian genus.
