Rhipsalis neves-armondii

Identification and new distributional evidence

The species resembles Rhipsalis floccosa subsp. pulvinigera, but the regional revision identified shorter terminal segments and magenta ripe fruits as useful differences. The lower floral region is embedded in the stem. Sterile plants require careful identification because a similar cylindrical habit recurs within the genus. Records of flowering and fruiting make subsequent comparison with the description more informative [Tortorelli et al. 2025].

Review of Minas Gerais specimens confirmed occurrence in that state and led to a proposed addition to its regional flora. The authors had few collections from the Atlantic Forest. Rarity in this sense describes regional documentation rather than automatically measuring total species abundance. POWO recognises a broader eastern Brazilian range extending south to Paraná [Tortorelli et al. 2025] [2-WWW].

Separating germination from survival

In the 2026 experiment, only six seedlings emerged at 35 °C, and all died before the trial ended. Seedlings also failed to survive the −0.4 MPa water-restriction treatment despite initial germination. Some seeds inhibited under adverse conditions retained the capacity to develop after conditions improved. The small thermal-treatment sample limits precision, but clearly demonstrates why newly emerged roots and surviving young plants should be followed separately [Gonçalo et al. 2026].

Floristic and taxonomic diversity of Rhipsalis (Cactaceae) in Minas Gerais state, Brazil

Tortorelli R. M., Gonzaga D. R., Peixoto A. L., Floristic and taxonomic diversity of Rhipsalis (Cactaceae) in Minas Gerais state, Brazil, Rodriguésia, 2025, 76:e00382025, doi: 10.1590/2175-7860202576058

Fieldwork and herbarium review produced a key and descriptions for 16 Rhipsalis taxa in Minas Gerais. The authors corrected several specimen misidentifications and confirmed regional occurrence of R. neves-armondii. Maps, habitat observations and a protected-area comparison show how accurate identification informs distribution and conservation assessment.

Higher temperatures and lower osmotic potentials negatively impact Rhipsalis Gaertn. (Rhipsalideae, Cactaceae) germination and seedling survival

Gonçalo R. R., de Souza Palma R. M., Gonzaga D. R., de Almeida O. J. G., Kolb R. M., Higher temperatures and lower osmotic potentials negatively impact Rhipsalis Gaertn. (Rhipsalideae, Cactaceae) germination and seedling survival, Plant Ecology, 2026, 227(1):5, doi: 10.1007/s11258-025-01581-3

Separate experiments tested eight Rhipsalis species at five constant temperatures and at osmotic potentials reduced with PEG 6000. Moderate temperatures generally favoured germination, while reduced water availability inhibited it and altered seedling survival. Transfers back to favourable conditions revealed species-dependent recovery of germination.
