as they appear, giving extension of range, and, in important cases, the 
localities. ) 
Gaylussacia dumosa T. & G., in a bog at Nottingham. 
Gaylussacia resinosa glaucocarpa Robinson, is more abundant in 
the coast towns of Rockingham county than the type; the fruit is 
larger, juicier, and more generally esteemed. 
Crantzia lineata Nutt. Abundant about the Great Bay in the 
Squamscot River, Exeter, and at New Market. 
Sanicula canadensis L. Seabrook and Kensington, among deciduous 
trees. 
Rhus venenata D.C., is too common in many swamps. 
Polygala cruciata L. Quite common on moist brackish grasslands, 
near the marsh. Seabrook, Hampton Falls and Hampton. 
Baptisia tinctoria R. Br. Common in sandy woods near the coast. 
Genista tinctoria L. This beautiful pest has been met with only 
at North Hampton, where it covers a space of about a square rod by 
the roadside. It is rapidly spreading. 
Lespedeza procumbens Michx. Nottingham, N. H., a few plants only. 
Lespedeza reticulata Pers. Kensington and Nottingham; sandy 
hills under deciduous forest. 
Lespedeza polystachya Michx. Nottingham and Kensington, with 
the last. 
Medicago Lupulina L. Not uncommon. 
Medicago arabica All. Quite plentiful in a cultivated field at South 
Hampton. Not elsewhere observed. " 
Cassia nictitans and Strophostyles approach the line at Amesbury 
and may be expected in the state. 
Two trees of Acer platanoides in a cemetery at Seabrook have 
started a numerous colony, but the saplings are not allowed to thrive. 
The seeds are spread broadcast by high northwest winds, and often 
travel one eighth of a mile, but as the soil is all cultivated none sur- 
vive save in fence rows. Doubtless these will persist.
