SILVA OF NORTH AMERICA. 101 
Pyrus sambucifolia, iv. 81. In the fourth volume of this work published in 1892 two species of Pyrus of 
the section Sorbus were admitted, Pyrus Americana, De Candolle, a widely distributed eastern species, and a tree 
of the northeast, referred to Pyrus sambucifolia, Chamisso & Schlechtendal, which is a species of northeastern 
Asia and which was believed to be widely scattered also through western North America and to cross the continent 
to the shores of Labrador. An examination of the type specimen of Pyrus sambucifolia preserved in the herba- 
rium of the Imperial Botanic Garden at St. Petersburg shows that that species differs from the plant which was 
figured in this Silva as Pyrus sambucifolia and from the different shrubby species of Sorbus of western North 
America. From these the eastern tree may be distinguished by its abruptly acuminate leaves and larger fruits 
usually in broader and more numerously fruited clusters. 
The tree of the northeast, the Pyrus sambucifolia of the fourth volume of The Silva, in its typical form is 
easily distinguished from Pyrus Americana by its broader abruptly acuminate blue-green leaflets, by its larger 
flowers which usually open eight or ten days later, and by its much larger fruits; but there are forms which appear 
intermediate between the two or are possibly hybrids between them, and the best observers are still in doubt whether 
this tree should be considered a species or a variety of Pyrus Americana. For the present, therefore, it may be 
well to consider it a variety, for which I suggest the name of decora in allusion to its handsome fruit. 
The synonymy of this tree would then be : — 
Pyrus Americana, var. decora. 
Sorbus aucuparia, B Michaux, Fl. Bor.-Am. i. 290 (1808). 
Pyrus aucuparia, Meyer, Pl. Lab. 81 (in part) (not Linneus) (1830). 
Pyrus sambucifolia, Gray, Man. ed. 5, 161 Gn part) (not Chamisso & Schlechtendal) (1868).— Macoun, 
Cat. Can. Pl. 146 (in part).—Sargent, Forest Trees N. Am. 10th Census U. S. ix. T4 (in part) ; Silva 
LV. Am. iv. 81 Gn part), t. 178, 174.—Maemillan, Metasperme of the Minnesota Valley, 288 (in part). — 
Rand & Redfield, #7. Mt. Desert Island, 98. 
Sorbus sambucifolia, Britton & Brown, Ili. F7. ii. 283 Gin part), £. 1976 (not Roemer) (1897). — Brit- 
ton, Man. 515. 
Pyrus Americana, var. decora ranges from the coast of Labrador to the northern shores of Lake Superior 
and to Minnesota, and southward to the elevated regions of northern New Hampshire, Vermont, and New York. 
Lyonothamnus floribundus, iv. 135. Extend range to San Clemente Island, California, where it was dis- 
covered in 1896 by Mrs. Blanche Trask. (See Hrythea, v. 30.) 
Hamamelis Virginiana, v. 3. This name was first published by Linnzus in 1759 in the tenth edition of the 
Systema (ii. 90). 
Rhizophora Mangle, v.15. The Mangrove grows in the United States probably only in Florida, and the 
previous statements that it grows on the delta of the Mississippi River and on the coast of Texas are, I now believe, 
erroneous. 
Eugenia procera, v.47. Add specific gravity of absolutely dry wood 0.9458 ; and weight per cubic foot 
58.91 pounds. 
Cornus florida, v. 66. Extend range to southeastern Kansas (Hitchcock, Flora of Kansas, xiii.). 
Nyssa Ogeche, v. 79. Extend range to the basin of the lower Appalachicola River, where it is very abundant 
on the borders of Cypress swamps down to within a few miles of the Gulf coast, and where it grows to the 
height of sixty or seventy feet, and usually forms several stems which are sometimes a foot and a half in 
diameter. 
The excellent quality of the honey made from the abundant nectar of the flowers of this tree is recognized, 
and bee farms have been established on the lower Appalachicola River in the neighborhood of the swamps where 
it grows. 
Nyssa aquatica, v. 83. Add to the bibliography of Vyssa aquatica of Linnzus, Linneus, Syst. ed. 10, 
ii, 1813 (1759). 
Sambucus glauca, v. 91. Extend range eastward through northern Idaho to northern Montana, where in 
July, 1896, I found it growing as a shrub from four to six feet in height near Columbia Falls, north of Flathead 
Lake. 
Viburnum Lentago, v. 96. Extend range to South Dakota, where it is common in the valley of the 
Minnesota River and in the valleys of the Black Hills, and occurs near Sioux Falls in the Sioux River valley (see 
Saunders, Bull. No. 64 South Dakota Agric. College, 196 [Ferns and Flowering Plants of South Dakota]) ; 
to the Big Horn Mountains of Wyoming, where it was found in August, 1900, by Mr. J. G. Jack, at an elevation 
of forty-three hundred feet above the level of the sea; and to eastern Kansas (Hitchcock, Flora of Kansas, xvii.).
