Stillingia sylvatica, known as queen's-delight or queen's delight, is a species of flowering plant in the family Euphorbiaceae. It was described in 1767. It is endemic to the south-central and southeastern United States, growing in sandy areas such as sandhills and pine flatwoods. It is an herb or subshrub averaging in height. It has alternate, ovate leaves with short petioles, reaching in length and in width. The leaf margins are serrulate to crenulate with incurved teeth. Each crowded inflorescence has four to seven staminate flowers and three to four pistillate flowers. Queen's delight flowers between March and June, fruiting from April to September.

05DNA & barcoding6 specimens
A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Stillingia sylvatica has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualStillingia sylvatica 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 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.
