Mexican weeping pine (Pinus patula) is regarded as an emerging environmental weed in some parts of Queensland and New South Wales. It is aslo seen as a potential environmental weed or "sleeper weed" in other parts of Australia. Fact sheets are available from Department of Employment, Economic Development and Innovation. Growth ring structure and wood density were compared among five families of Pinus patula planted in Malawi, Africa. The vertical and radial variations of wood density and growth characteristics were investigated in stems of year-old Pinus patula planted at a spacing of × by: 3. Taxonomic Notes. Synonyms: P. elliottii var. elliottii; P. heterophylla Varieties: none Description. P. elliottii is a perennial tree of the Pinaceae family native to North America. Seedlings have tall, thin trunks with open groups of needles. Distribution. P. elliottii is found along the southeastern coast of the United States from Texas to North Carolina.

THE IMPROVEMENT AND BREEDING OF PINUS PATULA W. Dvorak' Abstract: Pinus patula has a north to south geographic distribution in Mexico of approximately km. It is the most commonly planted commercial softwood in southern and eastern Africa and Colombia and is characterized by its good growth, straight stem form, and excellent pulping.
The demand for pine pulpwood in the Mpumalanga province of South Africa approaches two million tonnes per annum. To meet processor demand for low cost wood, it is important to maximize timber productivity per planted hectare. Selection of species for a site can significantly influence plantation productivity.
The aim of this study was to measure and compare the Cited by: 5. Palmer ER, Gibbs JA () Pulping qualities of plantation grown Pinus patula and Pinus elliottii from Malawi, vol Report No. L Tropical Products Institute, London, UK, p 36 Tropical Products Institute, London, UK, p 36Cited by: 9.
Twenty trees of Pinus patula, growing on five sites in Zimbabwe as part of a progeny test, were examined and their pulping characteristics determined. The trees were from the same full-sib family and were 12 years old.
No relationship between site, and wood density and fibre dimensions could be inferred because the differences between trees within a site were found. Adlard PG,Bailey CG,Austin S Wood density variation in plantation grown Pinus patula from Viphya Plateau, Malawi.

patula var. patula and P. patula var. longipedunculata. patula introductions have been planted in both the cool and wet tropical and subtropical regions of the tropical regions the introductions are mostly at altitudes.
Pinus elliottii Pinus elliottii is an important commercial timber species in its native range, which is in the lower coastal plain of southeastern USA, ranging from South Carolina to Florida. The natural habitat of P. elliottii is in the proximity of streams, swamps and bays where soil moisture is high.
Pinus patula, commonly known as patula pine, spreading-leaved pine, or Mexican weeping pine, and in Spanish as pino patula or pino llorón, (patula Latin = “spreading”) is a tree native to the highlands of Mexico. It grows from 24° to 18° North latitude and 1,–2, m (5,–8, ft) above sea level. The tree grows up to 30 m (98 ft) : Pinaceae.

Mexican weeping pine (Pinus patula), is native to the Sierra Madre Oriental in Mexico (Perry, ; Richardson and Rundel, ). It is well adapted to the physiographic and climatic conditions of the Eastern Highlands of Zimbabwe, where it is grown commercially together with Pinus taeda and Pinus elliottii (Crockford, ).
