01Narrative

Stylidium graminifolium, the grass triggerplant, is a dicotyledonous plant that belongs to the genus Stylidium (family Stylidiaceae). This species used to belong to the Stylidium graminifolium complex, but the name was conserved for this single species when two others were split from the complex and introduced as new species in 2001.Jackson, W.D. and Wiltshire, R.J.E. (2001). Historical taxonomy and a resolution of the Stylidium graminifolium complex (Stylidiaceae) in Tasmania. Australian Systematic Botany, 14(6): 937-969. S. graminifolium is endemic to Australia and is one of the Stylidium species with the widest distribution throughout Australia.Darnowski, Douglas W. (2002). Triggerplants. Australia: Rosenberg Publishing. It is a perennial plant with grass-like leaves and is easily cultivated. It has been considered to be a carnivorous or protocarnivorous plant because it possesses glandular trichomes underneath the flowers that can trap and digest prey.

05DNA & barcoding5 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 Stylidium graminifolium has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Stylidium graminifolium 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.

09Environmental DNA4 detections

Where the DNA of Stylidium graminifolium 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.
