506 FOREST CULTURE AND 
Persea Teneriffe, Poiret (sub Lauro). P. Indica, 
Sprengel. — Madeira, Azores, and Canary Islands. 
This magnificent tree produces a very beautiful, hard, 
mahogany-like wood, especially sought for superior 
furniture and turners’ work. One of the most hardy 
trees of the large order of Laurine. 
Peucedanum Sekakul, Bentham.—Egypt and Syria. 
Biennial. The root is edible. 
Peucedanum ecachrydifolium, Ledebour, — Persia. 
A valuable fodder-herb (Dr. Rosenthal). 
Peumus Boldus, Molina.—The Boldo of Chile. A 
small ornamental evergreen tree, with exceedingly 
hard wood, which is utilized for many kinds of im- 
plements. The bark furnishes dye material. The 
fruits are of aromatic and sweet taste (Dr. Philippi). 
Pisonia aculeata, Linné.—Tropical and sub-tropical 
countries of both hemispheres, extending as a native 
plant into New South Wales. This rambling, prickly 
bush can be chosen for hedge-copses. 
Pithecolobium dulce, Bentham.—Mexico. <A yalu- 
able hedge- plant. The sweet pulp of the pod is 
wholesome. 
Pittosporum tenuifclium, Banks and Solander.— 
New Zealand. This with P. eugenioides has proved 
exquisite for tall garden-hedges, for which these and 
several other species were first brought into notice by 
the writer. Our native P. undulatum is rather adapted 
for copses, and deserves cultivation also for the sake 
of its fragrant flowers, from which an essential oil 
can be distilled. 
Planera aquatica, Gmelin. — North America. An 
elm-like tree, which can be chosen for plantations in 
wet localities.
