Source-derived summary

Arthur John Cronquist (March 19, 1919 – March 22, 1992) was an American biologist, botanist and a specialist on Compositae. He is considered one of the most influential botanists of the 20th century, largely due to his formulation of the Cronquist system as well as being the primary co-author to the Flora of the Pacific Northwest, still the most up to date flora for three northwest U.S. States to date. Two plant genera in the aster family have been named in his honor. These are Cronquistia, a possible synonym of Carphochaete, and Cronquistianthus, which is sometimes included as a group within Eupatorium. The former was applied by R.M. King and the latter by him and Harold E. Robinson.

Life

Arthur Cronquist was born on March 19, 1919, in San Jose, California, but he grew up outside of Portland, Oregon, as well as in Pocatello, Idaho. His parents divorced when he was young and he and his older sister were brought up by his mother, who worked for the Union Pacific Railroad in Pocatello. The young boy was an avid member of the Boy Scouts of America, through which he gained an appreciation for the outdoors. He did his undergraduate work at the Southern Branch of the University of Idaho (now Idaho State University). During his time there he studied field botany under Ray J. Davis, who was compiling the Flora of Idaho at the time.

Editorial analysis

Why this record matters

The phrase “american botanist (1919–1992)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 29, 2026. The linked authority identifier is Q362245. VIAF identifies the subject as 61620062. The Library of Congress control number is n79018465. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1919 and 1992.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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
