The tulip-tree (Liriodendron tulipifera) is another member of the magnolia family with a relatively wide distribution in southeastern North America. This species is commercially important for its straight, clear lumber, and as an ornamental tree. 

XI. Order Ranales.—MagnoUacea or Magnolia Family.—Trees and shrubs having alternate leaves and single large flowers with calyx and corolla colored alike. Sepals and petals deciduous, anthers adnate. Carpels and stamens numerous. Bark aromatic and bitter. Fruit a collection of follicles dehiscing dorsally. 

A tropical to warm temperate family with some extension into north temperate zones (c.g., the tulip tree, Liriodendron tulipifera) the magnolias are familiar in our gardens and city parks. Some from this family are used as timber. 

Magnolia Field fluids properties, summarized in Table 1, are strikingly heterogeneous. Figure 5 illustrates this by way of a cross plot of fluid saturation pressure (bubble point and dew point pressures for oil and gas-condensate tests respectively) against measured reservoir pressure for available MDT samples. In very general terms, four fluid types may be defined. Undersaturated oils (solid circles in Fig. 5) are by far the most common. Noteworthy within this family are the two samples that have saturation...

B/sbenzylisoquinolins alkaloids isoquinoline alkaloids containing 2 fused benzylisoquinoline nuclei joined by one, two or three diaryl ether linkages. The ether linkages arise by phenol oxidation. B. a. occur in plants of the Menispermaceae and related families, which include the genera Berberis, Magnolia, Daph-nandra and Strychnos.
