Justicia brandegeeana, the Mexican shrimp plant, shrimp plant or false hop, is an evergreen shrub in the genus Justicia of the acanthus family Acanthaceae, native to Mexico, and also naturalized in Florida. It grows to 1 m tall (rarely more) with spindly limbs. The leaves are oval, green, 3–7.5 cm long. The flowers are white, extending from red bracts which look somewhat like shrimps, hence the common name "shrimp flower". The specific epithet is named for the American botanist Townshend Stith Brandegee (1843–1925). It is sometimes misspelled "brandegeana".

06Genome at a glanceCCDB
The complete instruction manualJusticia brandegeeana 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.

09Environmental DNA4 detections
Where the DNA of Justicia brandegeeana was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

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.
