01Narrative

Strobilanthes kunthiana, known as Kurinji or Neelakurinji in Malayalam and Tamil, is a shrub that is found in the shola forests of the Western Ghats in Kerala, Karnataka and Tamil Nadu. The purplish blue flower blossoms only once in 12 years, and gave the Nilgiri Mountains range its name, from the Tamil neelam (blue) + giri (mountain). Of all long interval bloomers (or plietesials) Strobilanthes kunthiana is the most rigorously demonstrated, with documented bloomings in 1838, 1850, 1862, 1874, 1886, 1898, 1910, 1922, 1934, 1946, 1958, 1970, 1982, 1994, 2006 and 2018, these have no match to Solar cycles. The Paliyan tribal people living in Tamil Nadu used it as a reference to calculate their age.Mike Kielty, Thursday Online, The Lost Gardens of the Raj (2008-3-4) This plant flowers during September–October.

05DNA & barcoding1 specimens

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 Strobilanthes kunthiana has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Strobilanthes kunthiana 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 Strobilanthes kunthiana 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 strong is each trace?

DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.

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.
