Stanleya viridiflora
species of plant
Stanleya viridiflora is a species of flowering plant in the family Brassicaceae known as green princesplume and green-flowered prince's plume. It is native to the western United States, where it occurs in sagebrush and plateau habitat, often on rocky calcareous, sandstone, clay, shale, or volcanic soils.
It is a perennial herb producing a stout erect stem which may exceed a meter in maximum height. It is hairless and sometimes waxy in texture. Its base is a caudex which is generally covered in the remains of withered leaf bases. The leaves have lance-shaped or oblong blades which have smooth or toothed edges or may be divided into a few lobes. The blades may be 22 centimeters long. Some are borne on long petioles, while others, especially those higher on the plant, clasp the stem at their bases. The top of the stem is occupied by a long inflorescence which is an open raceme of many flowers. Each flower bud is enclosed in long, thick sepals which open to reveal yellow or whitish petals each measuring up to 2 centimeters in length.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Stanleya viridiflora”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.
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 Dec 21, 2023. The linked authority identifier is Q7600078. 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.
