Japanese chestnut + Horned melon

Japanese Chestnut (Castanea crenata) is a species of chestnut originally native to Japan and South Korea. It is a small to medium-sized deciduous tree growing to 10-15 m tall. The leaves are similar to those of the Sweet Chestnut, though usually a little smaller, 8-19 cm long and 3-5 cm broad. The flowers of both sexes are borne in 7-20 cm long, upright catkins, the male flowers in the upper part and female flowers in the lower part. They appear in summer, and by autumn, the female flowers develop into spiny cupules containing 3-7 brownish nuts that are shed during October.

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]
