Strophostyles umbellata, commonly known as the pink fuzzybean or perennial wild bean, is a species of perennial flowering plant in the family Fabaceae. It is native to fields and woods in the southeastern and central United States. It blooms from June to September. This species is best distinguished from its congeners by its thick, relatively straight keel petal, held close to the banner petal. It also uniquely possesses a perennial, branched caudex at its base. It is most similar morphologically to S. helvola, the differences being that S. helvola has a much thinner keel, curving away more from the banner petal throughout its length. Its leaf morphology can be highly variable, ranging from the highly lobed panduriform shape typical of Strophostyles helvola, to the thin, sericeous, lanceolate leaf typical of S. leiosperma. Strophostyles umbellata individuals tend to be scattered from one another, which, possibly combined with self-incompatibility, can contribute to their observed low pod set. Like S. helvola, its seeds also possess a cellular, waxy coating, which may aide in buoyancy and water dispersal.

06Genome at a glanceCCDB
The complete instruction manualStrophostyles umbellata carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
Chromosomes & ploidyhow the DNA is packaged
2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants.

How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
