DEFAULTSORT Epidendrum radicans is a species of orchid. Common names include ground-rooting epidendrum, fire-star orchid, rainbow orchid, and reed-stem epidendrum.Epidendrum radicans. Royal Botanic Gardens, Kew. It is a common roadside weed at middle elevations in Central America. It is a crucifix orchid, often confused with many other members of the section Schistochila, including E. calanthe, E. cinnabarinum, E. denticulatum, E. erectum, E. fulgens, E. ibaguense, E. imatophyllum, E. incisum, E. schomburgkii, E. secundum, and E. xanthinum, among others. The diagnostic characteristic of E. radicans is its tendency to sprout roots all along the length of the stem; other crucifix orchids only produce roots near the base.Dressler, R. L.: "Will the Real Epidendrum ibaguense please stand up?" American Orchid Society Bulletin, 58(1989) pages 796 - 800. Additionally, E. radicans flowers are resupinate, unlike the members of the Epidendrum secundum complex, E. fulgens, and many other crucifix orchids. E. radicans also differs from E. secundum by bearing no nectar in the flower.

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 Epidendrum radicans has left across the world's sequence archives.

The complete instruction manualEpidendrum radicans 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.

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.
