Synonyms

Ferocactus peninsulae var. gracilis (H.E.Gates) G.Unger 1992

Common Name : fire barrel cactus,

중국어명 : 神仙玉

* 중국식물도상고에서는 神仙玉을 공식 명칭으로 채택하고 Baidu 百科에서는 神仙玉와 刈穗玉(예수옥)을 공용하고 있다. 刈穗玉은 이전에 쓰던 명칭으로 일본어에서 유래한 듯 싶다. 일본에서는 두 가지 다 쓰이나 요즘은 신선옥으로 가는 추세이다

Wikipedia 설명

 

Ferocactus gracilis, the fire barrel cactus, is a species of Ferocactus from Northwestern Mexico.[2] This cactus gets its common name from the striking red coloration of its defensive spines and flowers.

 

Description

Ferocactus gracilis is a solitary cactus that grows up to 3 meters tall, with cylindrical or spherical stems reaching heights of up to 150 cm (59 in) and diameters of 30 cm (12 in). It has deep green stems with 16 to 24 slightly tuberculated ribs. The areoles are light gray bearing 7 to 13 central spines that are red, flattened, and up to 7 cm (2.8 in) long, with a slightly curved to hook-shaped yellow tip. Additionally, there are eight to twelve white radial spines, occasionally twisted and around 6 cm (2.4 in) long.

 

The plant blooms in spring to early summer, producing funnel-shaped flowers with a purple-red midvein and red, yellow to white margins, reaching lengths of up to 4 cm (1.6 in) and diameters of 3.5 cm (1.4 in). The elongated yellow fruits are about 2.5 cm (0.98 in) long and do not open at a basal pore. The seeds are round, black, shiny, and measure 1.7-2 mm (0.079 in) long and 1.1-1.3 mm (0.051 in) wide.[3][4]

 

Subspecies

There are four accepted subspecies:[5]

 

Ferocactus gracilis subsp. coloratus (H.E.Gates) N.P.Taylor Mexico (C. Baja California)

Ferocactus gracilis subsp. gatesii (G.E.Linds.) N.P.Taylor Mexico (Baja California: Islands in Los Angeles Bay)

Ferocactus gracilis subsp. gracilis Mexico (C. Baja California)

Ferocactus gracilis subsp. tortulispinus (H.E.Gates) Lodé Mexico (N. Central Baja California)

 

Distribution

Ferocactus gracilis is native to southern Sierra San Pedro Martir, south to Punta Prieta, and northern Baja California, Mexico, growing at elevations of 10 to 30 meters. It thrives in rocky hillsides, outwash fans, silt flats, and gravelly plains, often alongside other desert plants like Mammillaria dioica, Cochemiea hutchisoniana, Echinocereus engelmannii, Pachycereus pringlei, Stenocereus thurberi, Fouquieria burragei, Cylindropuntia cholla, Idria columnaris, Lophocereus schottii, and Stenocereus gummosus.[3]

 

Taxonomy

This species was first described in 1933 by Howard Elliott Gates who named it after its slender growth habit.[6]
