Hickory nut + Horned melon

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.

The horned melon, also called African horned cucumber or melon, jelly melon, hedged gourd, English tomato, melano, kiwano, or cherie, is an annual vine in the cucumber and melon family. It is considered to be the ancestor of the other cultivated melons. Often known by its nickname in the southeastern United States, blowfish fruit, it is grown for its fruit, which looks like an oval melon with horn-like spines. The fruit of this plant is edible, but it is used as often for decoration as for food. When ripe, it has a yellow-orange skin and a lime green jelly-like flesh with a tart taste, and texture similar to a cucumber. The horned melon is native to Africa, and it is now grown in California, Chile, Australia and New Zealand as well. [Wikipedia]
