82 HISTORY AND GEOGRAPHY OF TREES. PART I. 
Broussonétia papyrifera from Japan in 1751. Father D’Incar- 
ville introduced the Azldntus glanduldsa from China, also in 
1751; Jas. Gordon of Mile End, the Ulmus americana in 1752: 
that remarkable tree the Salisburza adiantifolia was cultivated 
by him in 1754; the parent tree, a male, still exists (see p. 78.), 
and from it, in all probability, originated all the male trees of 
the same species, not only i in Europe, but in North America ; 
he introduced the Sophora japonica in 1753, and the Cornus 
alternifolia in 1760. Archibald Duke of Argyll introduced 
the Larix microcérpa and the Smilax rotundifolia in the same 
year. John Ellis introduced Halésza tetraptera and diptera in 
1756 and 1758; Messrs. Kennedy and Lee, Zuénymus atro- . 
purptreus; Hugh Duke of Northumberland, Pinus resindsa ; 
Christopher Gray, Vibarnum nitidum. The Duke of Bedford 
cultivated Pinus rigida before 1759; and Populus dilatata, the 
Lombardy poplar, was introduced from Italy by the Earl of 
Rocheford in 1758. No fewer than fifty articles were introduced 
or cultivated by Miller during this decade. Among these are, 
Acer créticum; in 1752, probably the small tree still existing 
in the Chelsea Garden; A. O’pulus, heterophyllum, and tatari- 
cum; Daphne Cneorum and pontica, Lonicera tatarica, Mag- 
nolza tripétala, several species of Rhamnus, Thuja occidentalis, 
Tilia americana, Abies rubra, Pinus maritima and _ several 
others, Bétula lénta, Pyrus prunifolia, Cotoneaster tomentosa, - 
Daphne alpina, Liquidambar imberbis. Among the trees and — 
shrubs recorded in the period, without the name of the intro- 
ducer, are, 4 cer pennsylvanicum, Bérberis canadénsis; Cérasus: 
caroliniana, a beautiful sub-evergreen low tree from Carolina, too’ 
much neglected in England; Rosa sinica, Shephérdza canadénsis, 
Planera Richardi, and Oxyec Occus macrocarpus. 
From 1761 to 1770 (Geo. III.), twelve trees and forty shrubs 
were introduced. Jas. Gordon introduced, or had in cultivation, 
Tilia Alba, Bétula excélsa, | Clématis virginiana, VibGrnum cassé- 
néides and Lentago, Hypéricum alatum, and Euénymus verru- 
cdsus. John Bartram introduced Mitchélla repens; John 
Busch, Lédum palistre, Fothergilla alnifolia, Xanthorhiza apii- 
folia; Mr. Bennet, Zédum latifolium; George William Earl of 
Coventry, Kolreutér¢a paniculata from China, rica australis, 
and Salix retusa from Italy. John Greening cultivated Pavia 
flava; Joseph Brooks, Lrica stricta; John Cree, Bumélia ténax ; 
Dr. Fothergill, Populus heterophlla; ;_ Messrs. Kennedy and 
Lee, Cratee gus elliptica, pyrifolia, and that fine tree, Fagus fer- 
ruginea. Sir Joseph Banks introduced Rhodora canadénsis in 
1767; John Ord, Genista triquetra ; Peter Collinson, 4’Inus 
serrulata, and Vaccinium virgatum ; Hugh Duke of Northum- 
berland, Populus gree‘ca and leevigata ; ‘and Miller, Sambucus 
canadénsis, Genista pargans, and Rubus hispidus. The
