said to be in cultivation in the nurseries, notwithstanding its claims 
to a place in every collection of ornamental trees.”* 
The Dwarf White-flowering Horse-chestnut. P. mac- 
rosfachia.—-’T\iis superb spreading shrub was first brought promi- 
nently before the public in this country by H. W. Sargent, in his 
Appendix to Downing’s Landscape Gardening, where it is enthusi- 
astically described, and admirably pictured. He thus mentions a 
specimen in his own grounds. “ Our best plant at Wodenethe, 
twelve years old, is sixty feet in circumference and about eight feet 
high, and has, at the time we write, between three and four hundred 
racemes of flowers, the feathery lightness of which, and the fine 
umbrageous character of the leaves, render it a most striking and 
attractive object.” It comes into bloom late in June, and con- 
tinues blooming a long time. 
The California Buckeye, ypscidiis calif ornica.^ is described in 
the Pacific Railroad Survey as a low, spreading shrub or tree, eight 
to twenty feet high; “flowers rose-colored, racemes about six inches 
long, from spring to midsummer.” 
The following general remarks on the dwarf varieties are from 
Loudon’s Trees and Shrubs of Great Britain, page 134: “The 
most valuable varieties of both ^sciilus and Pavia are best per- 
petuated by budding or grafting, and collectors ought always to 
see that the plants they purchase have been worked. Pavia rubra 
as a tree, P. discolor either as a shrub or grafted standard high, and 
P. macrostachia as a shrub, ought to be in every collection, whether 
small or large. t Pavia humilis, when grafted standard high on the 
common horse-chestnut, forms an ornament at once singular and 
beautiful. As the horse-chestnut is found on most plantations

t This remark probably applies the word “small ” to parks of five to ten acres. Of course it 
would be absurd to recommend that every owner of a half acre or acre, devoted to decorative 
planting, in this country, should attempt to have a specimen of every fine variety; tmless Jie
