the mountainous parts of Burmah is perhaps the 
largest single rose in existence, with white flowers 
as large as the smaller varieties of Magnolia grandi- 
flora. It has been in European gardens for ten or 
twelve years past. These two species and R. sem- 
pervirens lechenaultiana from the mountains ot South 
India are good representatives of the tender species 
of rose. 
The wonderfully mixed roses of our gardens are 
often impossible of reference to any species, and it 
is only from a knowledge of their hardihood that 
they can be guessed at. R. gallica, R. centifolia, 
R. damascena, etc., have all contributed Hybrids, 
and natural varieties, some of them perhaps hun- 
dreds of years ago before written records were in 
vogue. I :annot conceive of anything more inter- 
esting than the following out of these processes 
upon the newer species, so well adapted to the va- 
rious sections of the United States. As an example 
of what may be accomplished in this direction 
PARK and Cemetery recently figured a group of 
hybrids of the hardy Rosa Wichuriana raised by a 
former curator of the Cambridge (Mass.) Botanic 
Garden, W. A. Manda, now of South Orange, N. J. 
Cydonia of the Genera plantarum has 4 species. 
This, as I understand it, is made a synonym of 
Pyrus again in some of the later Kew publications. 
I should really be afraid to say how often its name 
has been sent back and forth like a shuttle during 
the last twenty-five years. C. Japonica and its pink, 
white and yellow varieties are among the best flow- 
ering shrubs of our gardens, and make excellent 
hedges. A fruit recently inquired about at the south

appears to be the fruit of C. cathayensis of Hems- 
ley. The common quince -and C. Maulei are the 
other species. All are subject to variation. 
Pyrus has about 52 species, all natives of north- 
ern temperate regions. This number is actually in 
cultivation, and the varieties are endless. The 
genus is in several sections, of which the pear, the 
apple, the rowan trees 
and the medlar, etc., 
are representatives. 
The flowering crabs 
of various kinds, both 
native and Asiatic, 
are among the great- 
est ornaments of the 
garden.

in the Genera plan- 
tarum, and given one 
or two species from 
Europe and Asia. 
In the arboretum list 
it is made a section 
of Pyrus, as shown 
above. I mention 
these discrepancies a 
little particularly be- 
cause the director of 
the Royal Gardens 
informed me with 
some circumstance a 
few years ago that 
the Genera Plantarum was the guide of that 
great institution in all that pertained to classi- 
fication and nomenclature. Of course the arboretum 
lists “must still be regarded as in some sense pro- 
visional and open to correction.” No doubt the next 
edition will be revised, or maybe we are going to 
get a new edition of the Genera Plantarum itself. 
Cotoneastcr has 18 species in northern temperate 
regions, including the mountains of South India 
and Mexico. They are naturally evergreens, with 
small dark foliage and scarlet berries. They are a 
good deal trained on walls in Europe. In the States 
such care is rarely taken, and they lose their foliage. 
The Great Orm’s Head is the only locality in 
which C. nummularia has been found wild in Britain. 
Crataegus , “hawthorn,” has 65 species of gen- 
erally very handsome low trees and shrubs. They 
also all belong to the northern hemisphere. There 
are a few evergreens. C. pyracantha is said to have 
naturalized here and there south of New Jersey. 
Further north it gets browned sometimes, but forms 
fine hedges, with bunches of orange-scarlet fruits, on 
Long Island. The English C. oxycantha has many 
varieties, all handsome, and several native species 
with showy scarlet or yellow fruit are more appre- 
ciated in Europe than their own country.
