H. tomentosa Xutt. var. tomentosa. Beech-hcatli, Hudsonia. 



Chiefly near the coast where common among dunes and near beaches in sands ; 

 also along" upper sandy shores of Ossipee Lake in Ossipee and Freedom where it 

 occurs with H. cricoidcs and H. tomentosa var. intermedia. 



\'ar. intermedia Peck. 



This ta.xon in Xew Hampshire is often found in the general vicinity of H. eneoides 

 and //. tomentosa and therefore since it is more or less intermediate in character 

 between the two, may then be a hybrid; more study is needed to show whether there is 

 genetic homogeneity in the specimens from all parts of the range ; common in sandy 

 valley of the Saco River at Conway and Bartlett and on shores of Ossipee Lake. 



Dirca palustris L. Leatherwood. 



Occurring occasionally and never abundantly ; probably throughout ; rich thickets, 

 moist ravines, and springy places. 



Daphne Mezereum L. Dai)hne. 



Well established in pasture-ravines in Durham: naturalized from Europe. 



Nyssa sylvatica Marsh. Black Gum,, Pepperidge, Sour Gum, Tupelo. 



•Swampy woods, shores of ponds and lakes at low elevations; occasional in south- 

 ern and east central Xew Hampshire, north to Conway and Holderness. 



Cornus florida L. Flowering Dogwood. 



Except for station in York and unverified report from Wintln-op, Maine, reaches 

 northeast limit of range in Strafford County, Xew Hampshire, where several exten- 

 sive stands occur on warm, dry south-facing slopes in deciduous forest ; farther south 

 in New Hampshire perhaps less strictlv confined to southern exposures ; plants 

 exhibit much genetic variation in our isolated colonies; biggest specimens commonly 

 attain heights of 25 feet or more : no named forms have been collected in New 

 Hampshire. 



C. stolonifera Michx. Red Osier. 



Occurring throughout at low elevations, common in northern X^ew Hampshire 

 becoming less frequent southward : often cultivated and perhaps sometimes escaped 

 from cultivation in southern Xew Hampshire ; swampy woods, thickets and edges of 

 ponds and streams : f . repens \"ict., depressed and rooting at nodes is occasional. 



C. rugcsa Lam. Round-leaved Dogwood. 



Generally distributed at low elevations; locally common southward, becoming in- 

 frequent northward: rocky or dry wooded slopes and talus north to Stark: specimens 

 approaching forma eueyela Fern., with leaves orbicular have been seen in New 

 Hampshire. 



C. Amomum Mill. Red Willow. 



Difficult to distinguish at all times from C. ohiiqua which it resembles in many 

 ways and with which it apparently crosses; C. .luionntm is common at low elevations 

 in southern and central Xew Hampshire, north to Madison and Lebanon; swamps, 

 shores of ponds, and streams and thickets. 



C. obliqua Raf. Silky Dogwood. 



Common in loAver Connecticut Va'Uev, less common elscnvhere in southern and south 

 central Xew Hampshire, north to Lebanon. Grantham, and Alton; in same habitats 

 as last. 



C. racemosa Lam. Gray Dogwood. 



Locall}' common in southeastern and east central Xew Hampshire, north to Wolfe- 

 boro ; outlying station in Bath; open swamps, roadsides, and thickets, often in heavy 

 soils.
