1904] Collins,— The Black Spruce in Rhode Islam! 41 



/uncus brachycarpus, Engelm.. found locally on the coast of New 

 Haven County, Connecticut, and of Plyuiouth County, Massacluisetts, 

 will possibly be found in light soil near the coast of Rhode Island. 



/uncus bulbosus, I^., similar to /.subtilis, but with more numerous 

 flowers in glomerules and blunt capsules, occurs in water and in 

 boggy places in Labrador, Newfoundland, and on Sable Island, Nova 

 Scotia, and should be sought on our northern borders. 



/uncus castaneus, ]. E. Smith, found on Newfoundland and Anti- 

 costi, and common on the northern Rocky Mountains, may yet be 

 discovered on the mountains of northern New England. 



/uncus conghttieratus^ L. (/. Leersii, Marsson) similar to /. effusus, 

 var. compactus, but with more rigid costate scapes, and with capsules 

 tipped by a crown-like blunt mucro, occurs in southern Newfound- 

 land and Nova Scotia and possibly reaches eastern Maine. 



/uncus dichotomus, Ell., known near the coast of Connecticut and 

 of Massachusetts, is to be sought in Rhode Island. 



/uncus oroncnsis, Fernald, occurs on Rangeley Lake, Maine, and 

 is probably in damp thickets or swamps of Coos County, New 

 Hampshire. 



/uncus scirpoidcs, Lam., has been reported from various New Eng- 

 land stations, but all the specimens seen by the writer have proved to 

 be other species. It occurs, however, along the coast from Florida 

 to Long Island, and may well be expected to extend northward to 

 Cape Cod. 



/uncus sfjj^ius, var. a^nericanus, Buchenau, one of the rarest and 

 most evasive of American rushes, has been known in bogs of Somer- 

 set County, Maine, and Jefferson County, New York. It may, there- 

 fore, be hopefully sought in northern New Hampshire and Vermont. 



/uncus trifidus, var. motianthus, Blufif & Fingerhuth, Compend. Fl. 

 Germ. sect. i. (1825) 440, with the numerous basal leaves equalling 

 the slender culms (2.5-6 dm. high) occurs locally along the moun- 

 tains from Ulster County, New York, to Virginia and North Carolina, 

 and should be looked for in New England, especially in Litchfield 

 County, Connecticut, and Berkshire County, Massachusetts. 



/uncus Vaseyi Engelm., found locally near the Rangeley Lakes, and 

 in the Penobscot and St. John valleys, Maine, and in the valley of the 

 Black River, Jefferson County, New York, is to be expected in north- 

 ern New Hampshire and Verjnont. 



The Black Spruce in Rhode Island. — In 1888 Mr. J. L. Bennett 

 recorded^ Picea nigra. Link, as occurring in "Johnston, Foster, etc." 

 Apparently no specimens were preserved by him to corroborate this 

 statement and as a result certain botanists have been somewhat skep-
