Source-derived summary

Isatis is a genus of flowering plants in the family Brassicaceae, native to the Mediterranean region east to central Asia. Its genus name, Isatis, derives from the ancient Greek word for the plant, ἰσάτις. The genus includes woad (Isatis tinctoria). Due to their extremely variable morphology, the Asian species in particular are difficult to determine; the only reliable diagnostic feature is the ripe fruit. They are (usually) biennial or perennial herbaceous plants, often bluish and hairless or downy hairy with the upright stem branched.

Description

They are annual, biennial or perennial, branched herbs, usually glabrous and glaucous except silique. Basal leaves generally elliptic-oblong, sessile; sessile caulinary, rounded to oval-oblong.

The hermaphrodite flowers are fourfold double perianth. The four sepals are ascending to upright. The four yellow to off-white or lilac-white petals are at least as long as the sepals.

Editorial summary

The public source identifies “Isatis” as genus of plants. This brief keeps that definition visible, then builds a research path around Isatis, genus and plants.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current 139-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Isatis, genus and plants providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Isatis”, the useful work is to connect “genus of plants” to the records capable of establishing context and consequence.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 3, 2026. The linked authority identifier is Q157382. None of the 0 selected statements returned an explicit reference.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
