01Narrative

Hymenoxys robusta is a South American species of flowering plant in the daisy family. It has been found primarily in Bolivia with a few populations in nearby Peru and Argentina.Kittie Lucille Fenley Parker. 1962. South American Species of Hymenoxys (Compositae). Leaflets of Western Botany 9: 197-224 descriptions in Latin and English, commentary in English, pages 207-208Kittie Lucille Fenley Parker. 1962. South American Species of Hymenoxys (Compositae). Leaflets of Western Botany 9: Plate 1 distribution map; key to symbols on page 200Kittie Lucille Fenley Parker. 1962. South American Species of Hymenoxys (Compositae). Leaflets of Western Botany 9: Plates 2 + 4 line drawings; captions on page 200Cabrera, A. L. 1978. Compositae. 10: 1–726. In A. L. Cabrera (ed.) Flora de la Provincia de Jujuy: Republica Argentina. Instituto Nacional de Tecnología Agropecuaria, Buenos Aires Hymenoxys robusta is a foul-smelling perennial with a branching root. Leaves remain attached to the stem after they die and turn black. Flower heads contain disc flowers but no ray flowers.Rusby, Henry Hurd. 1893. Memoirs of the Torrey Botanical Club 3(3): 63 Cephalophora robusta

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 Hymenoxys robusta has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Hymenoxys robusta 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. Click any value below to see the underlying records and sources.
