Glaucidium palmatum
species of plant
Glaucidium is a genus of plants in family Ranunculaceae, comprising a single species Glaucidium palmatum (Japanese wood poppy; シラネアオイ Shirane-aoi). It is endemic to northern and eastern Japan on Hokkaidō and northeastern Honshū on mountains close to the Sea of Japan.
It is a rhizomatous herbaceous perennial plant growing to 40 cm tall with a rigid stem with two large (20 cm diameter) palmately lobed leaves at the top and small membraneous leaves lower on the stem. The flower is produced singly at the top of the stem, 8 cm in diameter, with four pink to pale purple (rarely white) petaloid sepals, numerous stamens and two carpels. The fruit is a cluster of follicles.
It is sometimes placed in its own family Glaucidiaceae, or in the past in the family Paeoniaceae. Paeoniaceae, however, has now been shown unequivocally to belong in Saxifragales, while Glaucidium is firmly in the family Ranunculaceae.
In cultivation, Glaucidium palmatum prefers a cool, moist, sheltered position in partial shade.
This brief starts where responsible research should: with the source description of “Glaucidium palmatum” as species of plant. 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 species of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 18, 2026. The linked authority identifier is Q135626. 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
