SILVA OF NORTH AMERICA. 
MYRICACEZ, 
a dye; and Myrica sapida,' which is distributed from the shores of 
southern Japan through southern China and Malaya to the subtropical western Himalaya, is often 
cultivated for its succulent aromatic scarlet fruit. 
In North America Myrica is not known to be injured by insects, and is not liable to serious fungal 
diseases.” 
The generic name, probably from wupixy, the ancient name of some shrub, possibly the Tamarisk,? 
was adopted for this genus by Linnzus, who discarded the older Gale of J. Bauhin.* 
In India the bark of Alyrica sapida is collected on the subtropi- 
ical Himalayas and exported to the plains, where it is used in tan- 
ning leather, in dyeing, and in native practice for its heating and 
stimulating properties (Brandis, Forest Fl. Brit. Ind. 495.— Bal- 
four, Cyclopedia of India, ed. 3, ii. 1029.— Pharmacographia In- 
dica, ui. 355) ; in Japan an astringent pigment obtained from the 
bark is employed to color and preserve fish-nets (Rein, Industries 
of Japan, 177).

* Nearly thirty species of fungi are known to infest Myrica 
Caroliniensis and Myrica cerifera in North America, but they are 
neither conspicuous nor destructive. The small Cluster Cup, Zci- 
dium myricatum, Schweinitz, is not uncommon at midsummer on the 
under side of the leaves, which are also attacked by species of 
Cercospora. The leaves of Myrica Gale are often blackened and 
eurled by Ramularia monilioides, Ellis & Everhart. Myrica pere- 
grina is attacked by a Rust, Cronartium asclepiateum, Fries, which 
forms scattered semigelatinous or waxy fibres on the under surface 
of the leaves. A similar form in Europe has as its cluster cup or 
ecidial stage a Peridermium which occurs on Pine-trees. A simi- 
lar Peridermium is frequently found on the leaves of Pinus rigida, 
Miller, which is often associated with Myrica peregrina. 
8 It has been suggested that Myrica is from pvpl(w, in allusion 
to the fragrance of these plants ; or from ptpw, to flow, as they 
often grow in the neighborhood of water.
