Justicia californica is a deciduous species of flowering shrub native to the deserts of southern California, southern Arizona, and northern Mexico. Its common names include chuparosa (or chiparosa, both colloquial Spanish terms for "hummingbird"), hummingbird bush, and beloperone. It can grow to 1.5 m in height and almost as wide. For a short time it bears succulent leaves about 1.5 cm in width. It loses its leaves and then produces plentiful tubular flowers about 2.5-4 cm long between February and June. These are usually in shades of bright to deep red, or sometimes yellow, with a two-lobed upper lip and a wide three-lobed lower lip that falls open to reveal the inside of the blossom. It is one of the northernmost distributed species of the mostly tropical genus Justicia. This is a low bush which grows in watered areas of dry, hot sandy regions or rocky terrain of the desert floor, usually below 750 m above sea level. Hummingbirds visit the bush to feed on the nectar. Other birds eat the sugar-rich flower centers. This plant is sometimes cultivated as a landscape ornamental in desert regions for its bright flowers and to attract birds. The plant is thought to have been eaten by Native Americans of the Southwest.

The complete instruction manualJusticia californica 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 DNA1 detections
Where the DNA of Justicia californica 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.
