== Etymology ==
The genus is named in honor of William Harris (1860–1920), an Irish botanist who served as the Superintendent of Public Gardens and Plantations in Jamaica.

== Description ==
'''Harrisia''' consists of night-blooming cacti with slender, cylindrical stems that can be erect, decumbent, or climbing.
* '''Stems''': Typically have few ribs (3 to 11) and lack a cephalium.
* '''Flowers''': Large, nocturnal, funnel-shaped, and usually white. They feature a long floral tube covered with scales and often hair or wool, but never spines (distinguishing them from ''Echinopsis'').
* '''Fruits''': Globose to ovoid, fleshy, and often brightly colored (red or yellow). They may be smooth or tuberculate and sometimes feature deciduous scales.
* '''Seeds''': Relatively large, black, and rough or pitted.

== Habitat ==
The genus has a disjunct distribution. It grows in tropical dry forests, coastal scrubs (Caribbean), and chaco shrublands (South America). Altitudinal range: 0–1500 m.

== Distribution ==
* '''Caribbean & North America''': Florida (USA), Bahamas, Cuba, Cayman Islands, Dominican Republic, Haiti, Jamaica, Puerto Rico.
* '''South America''': Argentina, Bolivia, Brazil, Paraguay, Uruguay.

== Species and Subspecies ==
Following Lodé (2015), 20 species and 2 subspecies are recognized:

* [[Harrisia aboriginum]]
* [[Harrisia adscendens]]
* [[Harrisia bonplandii]]
* [[Harrisia brookii]]
* [[Harrisia caymanensis]]
* [[Harrisia divaricata]]
* [[Harrisia earlei]]
* [[Harrisia eriophora]]
* [[Harrisia fernowii]]
* [[Harrisia fragrans]]
* [[Harrisia gracilis]]
* [[Harrisia martinii]]
* [[Harrisia pomanensis]]
** [[Harrisia pomanensis subsp. bonplandii]] (Note: Often listed as a species, Lodé treats it here)
** [[Harrisia pomanensis subsp. regelii]]
* [[Harrisia portoricensis]]
* [[Harrisia simpsonii]]
* [[Harrisia taetra]]
* [[Harrisia taylorii]]
* [[Harrisia tetracantha]] (formerly ''Roseocereus'')
* [[Harrisia tortuosa]]

== Taxonomy ==
Lodé maintains ''Harrisia'' as a distinct genus within the tribe '''Cereeae'''. He rejects the merging of these species into ''Echinopsis'', noting clear differences in seed morphology and floral structure. The inclusion of the Bolivian genus ''Roseocereus'' (as ''H. tetracantha'') is supported by molecular data.
