Casuarina

Casuarina is a genus of 17 tree species in the family Casuarinaceae, native to Australia, the Indian Subcontinent, southeast Asia, and islands of the western Pacific Ocean. It was once treated as the sole genus in the family, but has been split into three genera (see Casuarinaceae).

They are evergreen shrubs and trees growing to 35 m tall. The foliage consists of slender, much-branched green to grey-green twigs bearing minute scale-leaves in whorls of 5–20. The flowers are produced in small catkin-like inflorescences; the flowers are simple spikes. Most species are dioecious, but a few are monoecious. The fruit is a woody, oval structure superficially resembling a conifer cone made up of numerous carpels each containing a single seed with a small wing. The generic name is derived from the Malay word for the cassowary, kasuari, alluding to the similarities between the bird's feathers and the plant's foliage, though the tree is called rhu in current standard Malay.

Casuarina species are a food source of the larvae of hepialid moths; members of the genus Aenetus, including A. lewinii and A. splendens, burrow horizontally into the trunk then vertically down. Endoclita malabaricus also feeds on Casuarina. The noctuid turnip moth is also recorded feeding on Casuarina.

Casuarina (schooner)

The Casuarina schooner was purchased by Nicolas Baudin at Port Jackson (Sydney) in 1802, during the Baudin expedition to Australia. She was a locally built schooner.

Baudin left France with two ships, Géographe and Naturaliste. The Naturaliste was sent home from Port Jackson with the specimens collected to date. The Casuarina, under Louis de Freycinet, then accompanied Géographe on the expedition, and conducted the close inshore survey work not possible in the larger vessel.

By July 1803 Baudin and many of the crew were ill; Baudin abandoned the survey to return home to France. In September 1803 Baudin died at Isle de France (Mauritius), and the Casuarina was abandoned there.
