Stereospermum tetragonum, the yellow snake tree, is 15–20 m tall, trunk 15–25 cm in diam, large leaves 25–50 cm; leaflets 3–6 on each side of midrib, long elliptic, 8-14 X 2.5–6 cm. Large, pale yellow, trumpet shaped flowers occur in panicles. Flowers are pale yellow, slightly curved, about 2 cm, upper lip 2-lobed, lower lip 3-lobed, tomentose at mouth, tube terete.

Dendrobium tetragonum, commonly known as the tree spider orchid, is a variable species of epiphytic or lithophytic orchid endemic to eastern Australia. Tree spider orchids are unusual in having pendulous pseudobulbs that are thin and wiry near the base then expand into a fleshy, four-sided upper section before tapering at the tip. There are only a few thin but leathery leaves at the end of the pseudobulbs and up to five flowers on relatively short flowering stems. To allow for the variations in the species there are five subspecies and a variety, some with a unique common name.

It is native to Primorsky Krai in Russia, South Korea, central and southern Japan, the northern Ryukyu Islands, and New Caledonia some 6,800 km (4,200 mi) away. A biennial halophyte, it can be found growing at the high tide line in coastal wetlands and in salt marshes. It is collected in the wild and eaten as a vegetable, and is considered to have medicinal properties. There appears to be an ornamental cultivar, 'Confetti'.
