Harrisia fragrans
''Harrisia fragrans'' (syn. ''Cereus eriophorus'' var. ''fragrans'') is a rare species of cactus known by the common names fragrant prickly apple and Caribbean applecactus. It is endemic to Florida, where it is known mainly from St. Lucie County. The plant's habitat has been almost completely consumed by development, leading to its rarity. It is a federally listed endangered species of the United States.
==Description==
This is an erect or spreading cactus with narrow, long stems which can well exceed one meter in length, at times approaching five meters.〔(【引用サイトリンク】title=''Harrisia fragrans'' in Flora of North America @ efloras.org )〕 It is covered in long, yellow or yellow-tipped spines which may be up to 4 centimeters long.〔 It produces enormous tubular flowers up to 20 centimeters long which are sweet-scented and white to pinkish in color.〔 They bloom at night. The fruit is spherical and red or orange in color, measuring up to 6 centimeters wide. The fruits are a favorite food of local birds,〔 which likely help to disperse the seeds.〔 The cactus has been noted to live at least 19 years, and in general has low fecundity; older, larger plants are more likely to survive, and they have higher fecundity, as well.〔 Small plants may benefit from growing with nurse plants.〔
