Cleistocactus inquisivensis is a species of cactus. It has been treated as Samaipaticereus inquisivensis and Yungasocereus inquisivensis, before being transferred to Cleistocactus in 2023. When placed in Yungasocereus, it was the only species.
Description
Cleistocactus inquisivensis is a columnar cactus, appearing either as a tree or shrub, ranging up to 4–5 meters in height. The {{cvt|6–7|cm}} diameter stems are dark green, with 6-10 ribs. The {{cvt|1.5–3|cm}} spines are in groups of 4-12, with no differentiation into central and radial types, and range from a brownish to grayish color. The flowers are white, appearing in groups of 5-8 near the stem tips. They open day and night and are {{cvt|5 to 6|cm}} long.
The fruits have a length between {{cvt|2 and 2.8|cm}}. They contain small, broadly oval, shiny black, slightly keeled seeds on the back, {{cvt|0.9|mm}} long and {{cvt|0.7|mm}} wide.{{cite book | last1=Anderson | first1=Edward F. | last2=Eggli | first2=Urs | title=Das grosse Kakteen-Lexikon | publisher=Ulmer | publication-place=Stuttgart (Hohenheim) | date=2005 | isbn=3-8001-4573-1 | language=de | page=646}}
Taxonomy
Martín Cárdenas described the species in 1957 from Inquisivi, placing it in Samaipaticereus.{{cite web | title=Au Cactus Francophone | website=Au Cactus Francophone | url=https://www.cactuspro.com/lecture/Cactus_Paris/Cactus_Paris-1957-57/page-19.de.html | language=fr | access-date=2023-09-04}} Friedrich Ritter later found the same species in Yungas. In 1980, he gave the cactus its own genus, Yungasocereus.{{cite web | title=Au Cactus Francophone | website=Au Cactus Francophone | url=https://www.cactuspro.com/lecture/Ritter-Friedrich/KakteenSudamerika2/page-300.de.html | language=fr | access-date=2023-09-04}} After a period in Haageocereus, the species was again separated into Yungasocereus. A 2023 molecular phylogenetic study led to Cleistocactus being expanded to include Yungasocereus and Samaipaticereus.{{Cite journal |last1=Romeiro-Brito |first1=Monique |last2=Taylor |first2=Nigel P. |last3=Zappi |first3=Daniela C. |last4=Telhe |first4=Milena C. |last5=Franco |first5=Fernando F. |last6=Moraes |first6=Evandro M. |date=2023 |title=Unravelling phylogenetic relationships of the tribe Cereeae using target enrichment sequencing |journal=Annals of Botany |volume=132 |pages=989–1005 |doi=10.1093/aob/mcad153 |name-list-style=amp |pmc=10808018 }} The expansion is accepted by Plants of the World Online {{as of|2025|March|lc=yes}}, with this species accepted as Cleistocactus inquisivensis.{{Cite POWO|title=Cleistocactus inquisivensis (Cárdenas) N.P.Taylor|id=3313556-4|access-date=2025-03-29|mode=cs1}}
Distribution
Cleistocactus inquisivensis is known only from Yungas and Inquisivi provinces of La Paz Department, where it is found at elevations of around 1000 to 2300 meters.{{citation needed|date=October 2023}}
