THE MISTLETOE. 267 
Other leafless forms exist also in India, Japan, Java, Mexico, and 
in South America. 
In this country, the False or American Mistletoe, Phoraden- 
dron Havescens , which resembles Vis cum album grows on decidu¬ 
ous trees from the pine barrens of New Jersey to the mountains of 
North Carolina and westward to Ohio and Missouri. This, too, 
has commercial value and is sent to the northern markets, but it is 
not so handsome as its English cousin. In the winter of 1871 a 
tiny mistletoe, Arceuthobium pusillum, was found growing on 
the black spruce in Warren and Renselaer Counties, New York. 
This discovery incited collectors to hunt for new stations for the 
plant, with the result that it has since been found in the Adiron- 
dacks, in Maine, Vermont, New Hampshire, Massachusetts and 
Pennsylvania. The mistletoe in all these localities occurs chiefly 
on the black spruce growing in sphagnum bogs. Mr. J. G. Jack 
thus describes it :* “ This mistletoe is dioecious and the stam- 
inate and pistillate flowers are usually found on separate spruces, 
but sometimes on different branches of the same tree. At ma¬ 
turity this little parasite rarely approaches an inch in length; 
most commonly it is less than half an inch long.” In the vicinity 
of Tucson, Arizona, a semi-desert country, occur several species, 
among them Phoradendron villosum and P. californicum. The 
former has white berries and broad leaves, and grows mainly on 
the native ash and cotton wood. It is also found in California. 
The latter species has red berries and is nearly devoid of leaves. 
It hangs from the branches of its host, the cat-claw, the mesquite, 
or the palo verde. Along the rims of canons in this region occurs 
Razoumofskya robust a, destructive to pine trees. Certain species 
of Arceuthobium are native to the Pacific coast, one species being 
an enemy of the Monterey pine. 
. The island of Jamaica in the British West Indies is a spot rich 
in Loranthaceae, especially in the mountains. As one ascends 
from valley to mountain peak, the mistletoe may be discovered, 
now on a wayside bush, and now among the highest branches of a 
tall tree. And unless one looks sharply he may miss it altogether, 
intermingled as it is with the dense verdure of its host. On a
