01Narrative

Hymenothrix loomisii, the Loomis' thimblehead, is a North American species of flowering plant in the daisy family. It grows in the southwestern United States (Arizona, New Mexico, southern Nevada), and also in the Sierra Madre Occidental in western Chihuahua. There have been reports of populations in southern California but these are most likely introductions.Biota of North America Program 2014 county distribution mapSEINet, Southwestern Biodiversity, Arizona chapter Hymenothrix loomisii is an annual herb up to 70 cm tall. Each head has 10-20 yellow or cream-colored disc flowers but no ray flowers.Flora of North America, Hymenothrix loomisii S. F. Blake, 1927.Blake, Sydney Fay. 1927. Proceedings of the Biological Society of Washington 40(10): 49–50

05DNA & barcodingmolecular

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 Hymenothrix loomisii has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Hymenothrix loomisii 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.
