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: 0.3 (sum of 1 dataset Dataset Index scores)

Datasets
This dataset contains the digitized treatments in Plazi based on the original journal article Koval, Vladimir A., Karremans, Adam P. (2025): Stelis kolomeitsevae (Orchidaceae: Pleurothallidinae): a new species from Pichincha province, Ecuador. Phytotaxa 697 (3): 274-281, DOI: 10.11646/phytotaxa.697.3.6, URL: https://doi.org/10.11646/phytotaxa.697.3.6AbstractStelis kolomeitsevae, a new orchid species from the cloud forests of Mindo, Pichincha Province, Ecuador, is described and illustrated. The species belongs to Stelis subgenus Stelis and is morphologically similar to Stelis lancea, from which it differs by its shorter leaves (4.0– 6.5 cm vs. 6.0–10.0 cm), shorter petiole (0.5–1.0 cm vs. 1.5–2.0 cm), inflorescence up to three times longer than the leaf (vs. barely surpassing the leaf), smaller sepals (1.5–1.7 × 1.2–1.4 vs. 2.0–2.5 × 2.0) and shorter column (0.6 vs. 1.0 mm) with a 5-lobed clinandrium (vs. 3-lobed). Additionally, it is compared with other Ecuadorian species in the same complex, S. loejtnantii, S. protracta, and S. scitula, from which it is distinguished by smaller, narrow ovate leaves, shorter ramicauls, and distinct floral features, including a transversely hemispherical lip with an emarginate apex and a triangular callus along the dorsal middle. A digital composite plate of the taxonomic novelty, a distribution map of the new species and SEM photographs of details of the flowers are provided.
