Hickory nut + Japanese persimmon

Hickory (from Powhatan) is a type of tree, comprising the genus Carya (Ancient Greek: κάρυον "nut"). The genus includes 17?19 species of deciduous trees with pinnately compound leaves and big nuts. Five or six species are native to China, Indochina, and India (State of Assam), 11 or 12 are from the United States, two to four are from Canada and four are found in Mexico. Hickory flowers are small, yellow-green catkins produced in spring. They are wind-pollinated and self-incompatible. The fruit is a globose or oval nut, 2-5 cm (0.79-1.97 in) long and 1.5-3 cm (0.59-1.18 in) diameter, enclosed in a four-valved husk, which splits open at maturity. The nut shell is thick and bony in most species, and thin in a few, notably C. illinoinensis; it is divided into two halves, which split apart when the seed germinates.

Diospyros kaki, better known as the Japanese Persimmon, Kaki Persimmon (kaki [?]) or Asian Persimmon in North America, is the most widely cultivated species of the Diospyros genus. Although its first published botanical description was not until 1780, the kaki is also among the oldest plants in cultivation, known for its use in China for more than 2000 years. In some rural Chinese communities, the kaki fruit is seen as having a great mystical power that can be harnessed to solve headaches, back pains and foot ache .
