 pubescent, often glandular. Flowers ojiening about June 20 noticea- 

 bly small, I to I in. broad; ])etals oval, twice as long as wide; sepals 

 woollv, sometimes glandular, mucronate. Fruit irregularly globose, 

 composed of from 5 to 30 drupelets mostly large. Three measured 

 and counted: h in. high bv -j^ in. wide, 27 drupelets; j% m. by h m., 

 32 drupelets; "f in. bv ^ in., 32 drupelets. Ripening season from 

 August 1 to August 1.5. ' Verv edible, the crop often good but too much 

 small fruit. Tvpe in Kennelnmk, Maine. Abundant in Kennebunk, 

 Kennebuukport and Wells. Also seen in North Berwick, Biddeford

This is the most variable ]:>lant described in this paper. Its small 

 flowers distinguish it from all the others. Perhaps it should not be 

 put in either class. The cane is small at the base like a dewberry,

 down solely by the weight of the plant, only long canes ever becoming 

 prostrate.

 frond; in this layer are imbedded the oval unilocular sporangia, 

 sometimes slightly projecting; and through it issue the hairs. The 

 branches are contracted at the base; the branching is never very 

 abundant, and sometimes the fronds are nearly or quite simple. It
