PINASTER. See Pinus Pinaster. 
PINCENECTITIA TUBERCULATA. A synonym 
of Beaucarnea recurvata, the correct name of which 
is Nolina recurvata. 
PINE BLIGHT or PINE NEEDLE CAST 
(Lophodermium pinastri). A condition due to fungus 
attack, and peculiar to many species of Pinus, the 
Weyiaouth Pine being one of those exempt. The chief 
symptom is indicated by the second of the names above 
adopted. Old trees and seedlings are alike attacked, and 
the latter rarely recover in bad cases. Pines affected by 
the fungus show brown blotches upon the leaves, while 
the other portion assumes a purplish tinge. Hartig 
suggests, a8 a precautionary measure, the isolation of 
nursery-beds from older trees. Once the tissues are 
attacked there is little hope of recovery. See also Pinus 
—Fungi, Vol. IIL, p. 138. 
PINK. Pinks and Carnations are affected by a Rust 
known as Puccinia Arenarie (see Vol. IIl.). The 
disease is best combated by means of a weak solution of 
Bordeanx Mixture directly the spotted appearance is noted 
on the leaves.
