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. 

Tulip-tree (Liriodendron tulipifera L.) honey is reddish in color and has a pleasant aroma and flavor.

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.

The ranges of paper birch, Betulapapyrifera ( 2), and tulip tree, Liriodendron tuHpifera ( 18) illustrate the closeness of the hostplant transition zone (i.e. where the northern meets the southern) with that for the two P. glaucus races (cf.Fig. 7.12).

Figure 85. Preparation of troughs for tagging a tulip tree (Liriodendron tulipifera) forest (left to right H. Waller, J. S. Olson, and D. L. Nelson). Malleable perma-gum pipe-sealing compound was formed into a trough around plastic tape over smoothed bark and then supported by aluminum foil and wire. From Olson (1968).

Figure 87. Seasonal fluctuation of concentration in leaf litter and in saprophagous and predaceous arthropods in a tulip tree (Liriodendron tulipifera) stand experimentally tagged with Cs. The leaf-litter content of radiocesium increased in September following autunmal leaf drc, but then decreased due to leaching. The higher trophic levels of arthropod consumers also show the changing concentrations of which reflect changes in their food bases. The relative amplitudes of the curves illustrate the decrease in Cs concentrations through arthropod food chains. From Crossley and Reichle (1969).

The carotenes of one aphid (Macrosiphum liriodendri), that occurs in two colour variants have been studied in detail. This aphid, living on tulip trees Liriodendron tulipifera), exists in green and pink forms which appear to differ in their level of cyclizing enzymes. The green form have all cyclized carotenes, while the pink form have two partly cyclized and two uncyclized carotenes (Figure 7.17). It must be presumed the aphids have the necessary enzymes to cyclize lycopene. Many other insects, particularly aphids, contain carotenes along with other pigments. 

These remarks apply to all plant life, though of course, the absolute values differ from one species to another. For example (see Hoffer in Johnson, 1969), from 0.8 to 1.4 /tm, the tulip tree Liriodendron tulipifera) is characterized by reflectance 5% greater than that of the silver maple Acer saccharinimi) which has 5% more than the American elm (Ulmus americana). At the dip (1.5 /im), the positions are exactly reversed.
