\Cas`u*a*ri"na\, n. [NL., supposed to be named from the resemblance of the twigs to the feathers of the cassowary, of the genus Casuarius.] (Bot.) A genus of leafless trees or shrubs, with drooping branchlets of a rushlike appearance, mostly natives of Australia. Some of them are large, producing hard and heavy timber of excellent quality, called beefwood from its color.

For what it's worth - Westin has a place in the Grand Caymans named Westin Casuarina also!
