Rimacactus
genus of plants in the family Cactaceae
Rimacactus is a genus of cacti with the sole species Rimacactus laui. It is native to Northern Chile, and at one point was considered a part of Eriosyce.
Description
Rimacactus laui is a cactus species characterized by its spherical to elongated shoots, measuring up to 3 cm in diameter. These shoots exhibit a whitish-green to reddish coloration and possess a carrot-shaped taproot. The plant's barely visible ribs are segmented into warty tubercles, each bearing a small leaf remnant. The radial spines, numbering nine to thirteen, are thin, needle-like, spreading, and translucent white. They are up to 9 mm long and brittle, with no distinction between central and radial spines. The flowers are narrowly funnel-shaped, approximately 2 cm long and 1.5 cm in diameter, and sulfur-yellow with a whitish-yellow base. They often appear in clusters of up to six. The pericarpel of the flower is smooth or nearly smooth.
This brief starts where responsible research should: with the source description of “Rimacactus” as genus of plants in the family Cactaceae. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as genus of plants in the family Cactaceae. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jan 26, 2026. The linked authority identifier is Q30310228. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
