Japanese chestnut + Strawberry guava

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.

Psidium cattleianum, named in honour of notable English horticulturist William Cattley, commonly known as Cattley guava or Peruvian guava, is a small tree (2?6 m tall), bearing small red or yellow fruit, which are somewhat sour but sometimes eaten or made into jam. The red-fruited variety, PSIDIUM LITTORALE Var. Longipes, is known as strawberry guava; the yellow-fruited variety, PSIDIUM LITTORALE Var. Littorale (Lucidum) is variously known as lemon guava, ""Yellow-fruited Cherry Guava"", and in Hawaii as waiaw? and is usually smaller. Native to Brazil and adjacent tropical South America, it is closely related to common guava (P. guajava), and like that species is a widespread, highly invasive species in tropical areas, especially Hawai?i. It tends to form dense, monotypic stands which prevent regrowth of native species, and is very difficult to eradicate; it also provides refuge for fruit flies which cause extensive agricultural damage. As an invasive species, it is sometimes erroneously called Chinese guava. Cherry Guava is sporadically naturalised in coastal areas of Queensland and northern New South Wales. It is also naturalised on Lord Howe Island, Norfolk Island and Christmas Island (Navie 2004; Queensland Herbarium 2008).The yellow variety bears even more heavily than the red and generally has larger fruit.
