Melaleuca alternifolia is a small tree that can grow to about 7 m (20 ft) with a bushy crown and whitish, papery bark. The leaves are arranged alternately, sometimes scattered or whorled. The leaves are smooth, soft, linear in shape, 10–35 mm (0.4–1 in) long, and 1 mm (0.04 in) wide. They are also rich in oil with the glands prominent ...
Leaves of most plants include a flat structure called the blade or lamina supported by a network of veins, a petiole and a leaf base; [1] but not all leaves are flat, some are cylindrical. [ citation needed ] Leaves may be simple, with a single leaf blade, or compound, with several leaflets .
Lilium michiganense is a species of true lily commonly referred to as the Michigan lily. [3] It is a wildflower present in prairie habitats in the Great Lakes and Upper Mississippi Valley regions of the United States and Canada , from South Dakota through Ontario to New York , south to Georgia and Oklahoma .
Borers rarely bore tunnels in living trees, although when populations are high, adult beetles feed on tender twig bark, and may damage young living trees. One of the most common and widely distributed borer species in North America is the whitespotted sawyer ( Monochamus scutellatus ).

The leaves are simple, narrowly oblanceolate to linear, and borne in whorls of six to eight. [10] [11] [12] Cleavers have tiny, star-shaped, white to greenish flowers, which emerge from early spring to summer. The flowers are clustered in groups of two or three, and are borne out of the leaf axils. [13] The corolla bears 4 petals. [14]
For leaves to grow in whorls is fairly rare except in plant species with very short internodes and some other genera (Galium, Nerium, Elodea etc.). Leaf whorls occur in some trees such as Brabejum stellatifolium and other species in the family Proteaceae (e.g., in the genus Banksia). In plants such as these, crowded internodes within the leaf ...
The leaves emerge in mid-spring, but the flowers require day lengths of approximately 14 hours and 30 minutes to form, hence T. americana's range is limited to north of the 35th parallel. Time of flowering varies by several weeks depending on the latitude; early May in Canada and early June in the extreme southern extent.
