OUERNALES. 
The Juglans, Casuarina and Quercus Alliance. 
There are 6 tribes, 17 genera and 518 species in 
this group. 
They are generally characterized by a sterile 
amentaceous inflorescence, with male and female

flowers mostly on the same, but occasionally on 
separate plants. There is a wide difference in the 
appearance of the trees and shrubs of the various 
tribes, and in the character of their fruits. This, 
however, is just what a gardener desires for elfec- 
tive grouping on the ground. 
Carya “Hickory” has 12 species in North Amer- 
ica and Mexico. C. olivoeformis, the “pecan nut,” is 
found from Southern Indiana and Illinois to South- 
western Texas, generally along streams in the latter 
locality. Many attempts have been made to culti- 
vate this species northward, but rarely with suc- 
cess. It would seem that Indiana stock should 
stand a little northing. C. alba yields the common 
hickory nut at the north. Most species make goo'l 
looking trees when given plenty of room to spread. 
Juglans “walnut” has 8 or 10 species in the tem- 
perate and sub-tropical regions of the Northern 
Hemisphere, Jamaica being perhaps the most south- 
erly station. There are two or three varieties of 
nursery origin in cultivation, which are regarded 
as hybrids between Asiatic and American species. 
Like the hickories, they are good looking and use- 
ful trees, as well for their timber as their nuts, but 
they require sufficient room for development in or- 
namental plantations. J. regia, the so-called “Eng- 
lish walnut,” is a native of Asiatic countries, from: 
the Himalayas to the Caucasus. It will stand the 
winters in sheltered places in Southern New Eng- 
land and sometimes mature a crop of nuts, but is- 
more at home in California. In Cachmere walnut 
oil is largely used for culinary purposes. J. nigra is 
a very valuable timber tree, hardy much further 
north and on parts of the prairies, where I have 
heard of its growing to 40 feet in fourteen years. 
There are two or three North China and Japanese 
species now in cultivation, which promise very well 
in the Atlantic states, but it is not likely that their 
nuts will equal the persistently selected varieties 
of J. regia. 
Ptcrocarya, sometimes called the “Caucassian 
walnut,” has four species, all natives of temperate 
•Asia, from the Caucasus to Japan. 
Platycarya strobilacea is a native of China and is- 
the tree which Lindley called Fortunasa. It is the 
only species. 
Mynca, “sweet gale,” “sweet fern,” etc., has 40- 
species scattered over most warm and temperate 
regions other than Australia. Comptonia is includ- 
ed as a section. The fruits have frequently a waxy 
or fleshy covering to their nuts, and the plants are 
deciduous shrubs at the north, or sub-evergreen and: 
MYRICA RUBRA. 
evergreen shrubs, or small trees, in the tropics.. 
The fruits of some are eatable, but acid. M. ceri- 
fera and M. asplenifolia do well in sandy and dr}'- 
places. M. Gale is better with more moisture.
