the first horticulturist of his day, Nitraria Schdéberz in 1788. 
The following ample list was introduced by Conrad Loddiges 
during this period; the names having been supplied to us by 
the present Messrs. Loddiges, his sons: — Morus *tatarica and 
pennsylvanica; Cornus *circinata, Genista *sibirica, Rhodo- 
déndron *Chameecistus, Acer h¥bridum and trilobatum, Prinus 
dasycarpa, Bérberis daurica, Crateegus Oxyacantha 7dsea; 
Azalea specidsa crispa, nudiflora rubra, and nudiflora staminea ; 
Bétula sibirica, Am¥gdalus sibirica, Andromeda calyculata var. 
ventricosa, A’Inus pumila, Cornus sibirica, Rzbes triflorum, 
Caragana férox, Rosa acicularis and corymbosa, Thuja plicata 
and tatarica. Of these species introduced by Conrad Loddiges, 
those marked with a star were received by him from the cele- 
brated botanist and collector for the French government, André 
Michaux; almost all the others were received from William 
Bartram of Kingsessing, Pennsylvania. 
From 1791 to 1800 (Geo. III.), were introduced nineteen trees 
and fifty shrubs. John Bell introduced Juniperus daurica, and 
Azalea pontica. William Forsyth introduced Bérberis zlicifolia ; 
Sir George Staunton, Rosa bracteata; John Busch, Caragana 
jubata, and Rhododéndron chrysanthum ; Messrs. Lee and Ken- 
nedy, Rosa férox ; Messrs. Fraser, Quéreus triloba, tinctoria, 
palustris, and Banister. Conrad Loddiges introduced Atragéne 
austriaca and americana, C¥tisus * purpureus, Andrémeda * Ca- _ 
tesbze 7, Aralia hispida; and also, according to Messrs. Loddiges, 
M . Y APR. \ 4 a | 
Castanea americana, C¥tisus * supinus, Juniperus alpina and 
sibirica, Prinos lanceolatus and levigatus, Spiree‘a canadénsis ; 
Vaccinium * duxifdlium, elevatum, hispidulum, pumilum, /igtis- 
trinum; Vitis vulpina 4lba, v. migra, and v. rubra. Among 
the plants recorded in the Hortus Britannicus, as having been 
introduced in this decade, are, Carya porcina and amara, Pyrus 
spuria, Magndléa macrophflla, Andrémeda specidsa, Rosa sua- 
véolens, Prunus maritima, Pyrus auriculata, Quércus microcarpa, 
and several others. 
OF the nearly 500 hardy trees and shrubs introduced during 
this century, 108 are from the continent of Europe, 300 are 
from North America, 3 from Chili, 13 from China, 6 from 
Japan, 2 from the Cape of Good Hope, 33 from Siberia, 2 from 
Tartary, 1 from Egypt, 2 from Morocco, 1 from Aleppo, 1 from 
Barbary, and the remaining few chiefly from Asia. . 
In the early part of the century, the greater number of species 
appear to have been received by Peter Collinson, from Dr. Gar- 
den of Charlestown, John Bartram, Mark Catesby, and other 
collectors. The progress of introduction was interrupted during 
the eighth decade of the century (1771 to 1780), owing to the 
breaking out of the American war; but it revived with double 
vigour between 1780 and 1800, during which period by far the
