Names and species limits
In the study by Rosas-Reinhold, Sánchez and Arias, samples identified as Aporocactus flagelliformis, A. flagriformis and A. leptophis formed a single lineage. They were recognized as one species under the earliest name A. flagelliformis. Current POWO accepts this name. [Rosas-Reinhold et al. 2022, pp.425–431] [2-WWW]
Flowers and geography
The studied plants had zygomorphic flowers with pink to magenta tepals. Their main range extended through the Sierra Madre Oriental to central Veracruz. The revision associated this lineage with the northern part of the generic range. [Rosas-Reinhold et al. 2022, pp.430–432, Fig.3 i5]
Habitat and climatic niche
The genus occurs in cloud and pine–oak forests, on trees or rocky substrates. The authors compared climatic niche models for both species and found them to differ in the analysed dataset. The model describes associations between known localities and climatic variables. It is distinct from a direct experiment measuring tolerance in potted plants. [Rosas-Reinhold et al. 2022, pp.427–433]
Materials from the author's archive
The species also appears in Konrad Szychowski's private material archive. [Schumann 1890, file p. 17, 20]
