*24 Poteiitilla tricleiitata, Ait. 



On Hooksett " Pinnacle," a small rocky elevation eight miles above" Manches- 

 ter, there is a station of this species, which is usually found either at the seashore 

 or on high mountains. The " Pinnacle " is a little way back from the Merrimack 

 "river bank, rising to the height of some two hundred feet, the eastern and south- 

 ern sides being precipitous and mostly bare. 



[See Rhodora, i., 90.] 



*25 Hiidsonia ericoicles, L. 



There is an immense station of this species at Concord on the high sand bluffs 

 east of Merrimack river. The principal station exaniined extends along the top 

 and slope of the bluff for about 1500 feet from south to north. There is more on 

 the next bluff northward and still more south of tlie highway below the principal 

 station. The trees growing with it are mostly Pinus rigida and resinosa, Bettila 

 populifolia and Querciis ilicifolia ; grasses — Agt'ostis scabra, Deschampsia flexu- 

 osa, Dajit'honia spicata and Andropogo>i scoparius ; shrubs — Kalmia angitstifolia 

 and Myrica asplenifolia ; smaller plants — Comandra icmbellata and Polygala 

 polygama and two or three species of Antetinaria. The soil is dry and very nearly 

 clear sand. - There are no rocks in the vicinity.

*26 EpiloMiun strictiim, Muhl. 



Abundant at least as far north as Lake Winnipesauke. 



*27 Nyssa sylvatica, Marsh. 



The tupelo is much more abundant than is generally supposed. In the " rho- 

 dodendron swamp" (see Rhododendron 7)iaxivium below) there are very large 

 old trees which the woodman's axe has willingly spared. Large trees may be 

 recognized at a distance by the contour of the trunk, which has a columnar aspect, 

 the diameter diminishing but slightly from base to summit. The trunk is usually 

 bare for more than one-half its height and often appears as if broken off at the 

 top. The bark is very thick and rough and is seamed and cross-seamed in a 

 characteristic manner. 



^28 Rlioclocleiiclroii inaximimi^ L. 



A high, wet swamp, difficult of access, near the northwest corner of Manches- 

 ter, h^s long been known as a station of the beautiful "rose bay." The plants 

 are usually in flower about July 4th. The swamp having recently been denuded 

 of its trees the rhododendrons have not flowered as well as formerly and after 

 very cold winters the buds are mostly blighted. No success has attended the 

 transplanting of individuals.
