S-Index Interpretation
The S-Index (Sharing Index) is a comprehensive metric that represents the cumulative impact of all your datasets. It is calculated as the sum of Dataset Index scores across all your claimed datasets.
What it means:
- A higher S-index indicates greater overall impact of your datasets relative to typical datasets in their fields of research
- The S-Index grows as you add more datasets or as existing datasets gain more citations and mentions
- It provides a single number to track your research data impact over time
Current S-Index: 30.0 (sum of 10 datasets Dataset Index scores)

Datasets
This dataset contains the digitized treatments in Plazi based on the original journal article Kumar, Vikas, Thakur, Kamini, Kirschner, Jan, Štěpánek, Jan (2025): A new species of Taraxacum (Compositae, Crepidinae) from Arunachal Pradesh, India: Sexual reproduction detected in the group of Taraxacum sikkimense. Phytotaxa 720 (3): 263-272, DOI: 10.11646/phytotaxa.720.3.6, URL: https://doi.org/10.11646/phytotaxa.720.3.6AbstractTaraxacum diluculorum Vik. Kumar, Kirschner & Štěpánek, a new species of T. sect. Emodensia is described from the alpine region of Arunachal Pradesh, Indian Himalayan Region. It is distinct in having white flowers, yellow stigmas, light reddish ochraceous achenes with a short cone and is characterized by sexual reproduction. It is related to T. sikkimense (T. sect. Emodensia), another white-flowered Himalayan species; the name T. sikkimense is second-step lectotypified. There is also a similarity of T. diluculorum with T. suavissimum and T. austrotibetanum of T. sect. Tibetana. However, it differs from these latter primarily in its uniform pollen size, sexuality, colour of stigma, and achene morphology. A detailed comparison and illustrations of T. diluculorum and similar species are provided.
