Geobotanically, Missouri belongs to the North American Atlantic region, and spans all three floristic provinces that make up the region: the state transitions from the deciduous forest of the Appalachian province to the grasslands of the North American Prairies province in the west and northwest, and the northward extension of the Mississippi embayment places the bootheel in the Atlantic and ...
Missouri: Flowering dogwood: Cornus florida: 1955 [33] Montana: Ponderosa pine: Pinus ponderosa: 1949 [34] Nebraska: Eastern cottonwood: Populus deltoides: 1972 [35] Nevada: Single-leaf pinyon: Pinus monophylla: 1959 [36] Great Basin bristlecone pine: Pinus longaeva: 1987 [36] New Hampshire: American white birch: Betula papyrifera: 1947 [37 ...
The leaves are alternate, 7–18 cm (2 + 3 ⁄ 4 –7 in) long (rarely to 36 cm or 14 + 1 ⁄ 4 in) and 8–12 cm (3 + 1 ⁄ 4 – 4 + 3 ⁄ 4 in) broad (about twice as big as the white mulberry's leaves), [3] simple, broadly cordate, with a shallow notch at the base, typically unlobed on mature trees although often with 2–3 lobes ...
Three goals of plant taxonomy are the identification, classification and description of plants. The distinction between these three goals is important and often overlooked. Plant identification is a determination of the identity of an unknown plant by comparison with previously collected specimens or with the aid of books or identification ...
The leaves are compound pinnate, 20–30 cm long, with 5-11 (mostly 7-9) alternately arranged leaflets; each leaflet broad ovate with an acute apex; 6–13 cm long and 3–7 cm broad, with an entire margin and a thinly to densely hairy underside. In the fall, the leaves turn a mix of yellow, gold, and orange. [citation needed]
The leaves are eaten by four gall-producing insects of the genus Pachypsylla, which do not cause serious damage to the tree. A number of insects and fungi cause rapid decay of dead branches or roots of the tree. The small berries, hackberries, are eaten by a number of birds, [11] including robins and cedar waxwings, [12] and mammals. Most seeds ...
Mockernut hickory is monoecious - male and female flowers are produced on the same tree. Mockernut male flowers are catkins about 10 to 13 cm (3.9 to 5.1 in) long and may be produced on branches from axils of leaves of the previous season or from the inner scales of the terminal buds at the base of the current growth.
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.
