474: ARBORETUM AND FRUTICETUM. PART LI. 
introduced in 1820; flowering in June, ( 
July, and August. The shoots are slen- | 
der, spreading, and rooting at the joints | 
where they happen to rest on the soil, \ 
with ascendent extremities. The tree 
comes into flower about a month or six 
weeks later than the other 4sculacez, 
and continues flowering, in the case of 
large plants on moist soil, for three 
months or longer, forming one of the 
greatest floral ornaments of the shrub- 
bery, at a season when very few trees 
or shrubs are in flower. The fruit, which 
is small, seldom ripens in England; but 
in America it is said to be eaten, boiled or 
roasted: and M. Poiteau, accordingly, has included this species of Pavia in 
his list of fruit trees. (See Bon Jard., 1835, p.'775.) When plants are to 
be raised from the nuts, he says they ought to be sown immediately; as, if 
kept exposed to the air, they shrink, and soon lose their vegetative power. 
The flowers are agreeably fragrant, and, as before observed, very orna- 
mental; as are the spreading leaves, supported on long slender petioles ; 
which, from their graceful disposition, combined with the feathery lightness 
of the racemes of flowers, give the whole plant an air of elegance quite 
different from that of any other species of dwarf pavia. 
Statistics. The largest plant in the environs of London is at Syon; but it is not more than 12 ft. 
high. The plant of this species in the garden of the London Horticultural Society, 7 years planted, 
was, in 1834, 5ft. high. In Berkshire, at White Knights, there are a great many plants which flower 
profusely the whole season, and among them is one, 25 years planted, which is 15 ft. high; in Lanca- 
shire, at Latham House, one, 12 years planted, 10 ft. high; in Suffolk, in the Bury Botanic Garden, 
7 years planted, and 6 ft. high. ; and, in Surrey, at Farnham Castle, several plants, 10 ft. high. 
Commercial Statistics. Plants, in London, are 1s. 6d. each; at Bollwyller, 
2 francs ; and at New York, 25 cents, and nuts 50 cents per quart. 
App. i. Other Varieties of Pavia. 
In the Fulham Nursery are plants belonging to Pavia, or intermediate between Pavia and ’s- 
culus, with the names, Pavia serrata and P. erécta; and in the garden of the London Horticultural 
Society are plants marked  sculus Pavia flava var. In different nurseries, there are different 
names for the same variety ; and, as almost all the sorts seed freely, and hybridise as freely, both with 
ZE'sculus, and with each other, new varieties may be expected in abundance. All the species and va- 
rieties are so truly beautiful, that this is not to be regretted, more especially if they are kept distinct, 
and so described and named as to indicate what they are, and to enable purchasers to be certain of 
obtaining them. It is almost unnecessary to observe, that all the most valuable varieties are best 
perpetuated by budding or grafting, and that, with regard to the pavia, as well as to the esculus 
(see p. 469.), collectors ought always to see that the plants they purchase have been worked,

OF THE HARDY AND HALF-HARDY LIGNEOUS PLANTS OF THE 
ORDER SAPINDA‘CE. 
Or this order there is only one hardy ligneous plant in the country, namely, 
KOlreutéria paniculata Laxm. ; and the half-hardy species, which chiefly belong 
to the genus Dodona’a, are not much cultivated even in green-houses.
