Dischidia Dischidia is a genus of plants in the Milkweed family, Apocynaceae. They are epiphytes native to tropical areas of China, India and most areas of Indo-China.

Darwinia oxylepis Darwinia oxylepis, commonly known as Gillham's bell, is a plant in the myrtle family Myrtaceae. It grows as an dense, upright shrub 1.0 - 1.5 metres (3 – 4.5 ft) high and produces large numbers of red inflorescences prominently displayed on the ends of the branchlets in spring. It is one of a group of Darwinias including "D. leiostyla", "D. macrostegia", "D. meeboldii", "D. collina" and "D. squarrosa" collectively known as mountain bells. The species is found in only a few seasonally moist gullies near the lower slopes of the Stirling Range National Park and nearby Porongurup National Park and is therefore classified as endangered.
