Aguilar-García S. A., Figueroa-Castro D. M., Valverde P. L., Vite F., López-Ortega G., Pérez-Hernández M. A., Reproductive biology of Myrtillocactus geometrizans (Cactaceae) flowers with contrasting orientation, Plant Species Biology, 2022, 37(3):243-256, doi: 10.1111/1442-1984.12371
This paper compares phenology, floral structure, visiting insects and reproduction on opposing sides of Myrtillocactus geometrizans plants. Controlled pollination distinguishes pollen origin and measures of seed production. Differences in traits and floral timing are compared with similar reproductive success in the two orientations.
