Hatiora salicornoides (Haw.) Britton & Rose

Hatiora salicornoides, also spelt Hatiora salicornioides, the bottle cactus, dancing-bones, drunkard's-dream, or spice cactus, is a species of flowering plant in the cactus family. A member of the tribe Rhipsalideae, it often grows as an epiphyte, natively in eastern Brazil and ornamentally elsewhere.

Hatiora salicornoides grows to about 1 m (3 ft) tall with an erect to pendent growth habit. Its stems are composed of segments 1.5–5 cm (0.6–2.0 in) long. Each segment is shaped like a club or bottle, with the narrower end at the base. The stems branch from the end of a segment, with up to six branches forming a whorl. The yellow to orange flowers are borne at the ends of younger stem segments, and are 1–2 cm (0.4–0.8 in) long and about the same across when open. Translucent white berries follow the flowers.

The species was first described by Adrian H. Haworth in 1819, as Rhipsalis salicornoides. Haworth spelled the specific epithet as salicornoides; subsequent authors corrected the spelling to salicornioides, regarding the original as an orthographic error. The International Plant Names Index later deemed the specific epithet incorrectable to salicornioides as is it derived from a noun and a suffix rather than two Greek or Latin words. The epithet means "similar to Salicornia". The species was placed under the genus Hatiora in 1915, after previously belonging to the “lost” (and ultimately, abandoned) genus of Hariota. Molecular phylogenetic studies have confirmed its placement in the correct genus, and also in the tribe Rhipsalideae, showing a close relation to H. cylindrica (which has been considered synonymous with H. salicornoides, as a cultivar/form or variety). H. salicornoides is highly variable, as many succulent plants can be, and may possibly include other distinct species.
