118 HISTORY AND GEOGRAPHY OF TREES. PART GEE 
eight by Conrad Loddiges; six by Messrs. Lee and Kennedy ; 
three by Fraser ; nineteen by Lyon; one by the Kew Garden; 
one by the London Horticultural Society; one by Don ofthe 
Cambridge Botanic Garden; and one by Sir Abraham Hume. 
Among the most interesting articles introduced during this de- 
cade are, Rosa multiflora, Cunninghaméa lanceolata, Juniperus 
excélsa, Caprifolium jap6nicum, osa Banksia, Rhododéndron 
catawbiénse (by Fraser), and Crate’gus Aronia. It is some- 
what remarkable, that of such a number of species introduced 
during this decade, the names of so few of the introducers should 
be known; but it must be recollected that the means of intro- 
ducing were, at this period, principally by packets of seeds sent 
to the nurserymen by foreign correspondents, or by amateurs ; 
and that, as several years must necessarily elapse between the 
period of introduction, and that of flowering and naming, the 
name of the collector who sent the seeds, or of the nurseryman 
who first raised plants from them, is forgotten, or ceases to be of 
the same interest. ‘The case is different when living plants are 
brought into the country, and it is, in truth, chiefly of the intro- 
ducers of such that the names are known. 
From 1811 to 1820, three hundred and seventy-four trees 
and shrubs were introduced, viz., forty-four by Messrs. Loddiges; 
twelve by Lyon; four by Lee and Kennedy; three by Whitley 
and Co. (among which was Spirze'a bélla in 1820); three by the 
Horticultural Society (including Cotoneaster affinis in 1820); 
two by Fraser (Abies Fraserz, and Yucca angustifolia in 1811); 
one by Don of the Cambridge Botanic Garden ; one (the Rides 
sanguineum, in 1817) by Archibald Menzies, Esq., who sailed 
round the world with Captain Vancouver; Genista procimbens 
by Schleicher, a botanical collector in Switzerland;. one by 
Knight of the Exotic Nursery, King’s Road; and one (Mahonza 
fascicularis) by A. B. Lambert, Esq. Among the most valuable 
of the species introduced by Loddiges are, Azalea arboréscens, 
A. specidsa, and Ribes atreum, in 1812; Symphoria racemosa, 
C§tisus ruthénicus, Juniperus recurva, and Yécca tenuiflora, in 
1817; A’'Inus cordifolia (the most beautiful species of the genus), 
in 1818; Armeniaca brigantiaca, and Quércus stellata, in 1819; 
Crate gus melanocdrpa, C. latifolia, C. Olivierzana, Fraxinus 
pannosa, F. platycarpa, F.lancea, Pinus excélsa, and‘A’bies Pichta, 
in 1820. Among those introduced by Lyon are, Magnolia pyra- 
midata, in 1811; and Andrémeda floribinda, Nyssa candicans, 
Borya digistrina, B. porulosa, B. acuminata, Virgilia litea, and 
 Crateegus apiifolia, in 1812. Among the fine plants recorded 
as having been introduced in this decade, without mentioning 
the names of the introducers, are, Z’sculus glabra and pallida, 
and Pavia hy¥brida, in 1812; Bérberis sinénsis, Cydonia ja- 
ponieca, and Daphne Thymele’a, in 1815; Planera Richard:
