“…The continuous production of flower buds by Astrophytum ornatum is an unusual phenomenon, which had rarely been reported for any other species of cactus (Mandujano et al 2010), making this the first report of this cactus with a permanent or constant production of buds. This strategy could be considered energetically costly, since it implies a significant energetic cost that could otherwise be used for other vital processes.…”

“…The flowers are similar to those of other cacti of the Subfamily Cactoideae, and particularly to those of Astrophytum asterias (Zucc.) Lem., which is found in Northern Mexico (Martínez-Ávalos 2007Strong & Williamson 2007, Mandujano et al 2010.

“…In the Cactaceae flowering usually occurs in a specific period that can encompass several months with one to several peak flowering periods (Multiple big bang, i.e. Cereus hexagonus, Echinocereus coccineus, Neobuxbaumia mezcalaensis, Neobuxbaumia macrocephala, Stenocereus griseus, Stenocereus queretaroensis, Pilosocereus sp., among others) (Valiente-Banuet 1997, Ruíz et al 2000, Scobell & Scott 2002, Mandujano et al 2010, or can be very short lived of only a few days (Big bang, i.e. Ariocarpus fissuratus, Mammillaria pectinifera, Echinomastus erectocentrus, Echinocereus engelmannii var.…”

“…descriptions of their flowers, fruits and phenology), and only a limited number of studies integrate population-level reproductive dynamics. Mandujano et al (2010) systematized the current knowledge on the reproductive biology in the Cactaceae and showed that most species have bisexual flowers although some may be functionally or morphologically unisexual with relatively short floral life spans (1-2 days) with some opening for longer periods of up to six days. Most species are outcrossers but some species have mixed mating systems with no clear pattern regarding self incompatibility systems.…”

Controlled pollinations to determine the mating system and determination of the Outcrossing Index (OCI), the pollen /ovule ratio and breeding system. Results: Astrophytum ornatum produced flower buds throughout the year, but 89.2% of them were aborted. Four events of ephemeral flowering population were presented per year. The species is self-incompatible and controlled pollinations indicated pollinator limitation of several bee species. The OCI indicates that the species is facultative xenogamous, and pollen/ovule ratio indicates obligate xenogamy. On average there were 54 seeds/fruit and individuals produced 4 fruits/year. Conclusions: The continuous production of buds had rarely been reported for cacti. Intrapopulation bloom is one of the shortest recorded for the family and it produces high floral synchrony. The low number of seeds / fruit and flowers / individual, coupled with the narrow niche breadth of species and various anthropogenic factors place Astrophytum ornatum as a susceptible species to be extinct. Key words: continuous production of flower buds, reproductive success, breeding system, mating system, phenology Ecología reproductiva del "cactus estrella" Astrophytum ornatum (Cactaceae): una estrategia de reproducción continua con bajo éxito Resumen Antecedentes: No existen estudios precisos sobre la biología reproductiva de Astrophytum ornatum, especie endémica y en riesgo. Preguntas: ¿Cómo es la fenología de la especie? ¿Cuáles son los sistemas de cruza y apareamiento? y ¿Cuál es el éxito reproductivo? Especie de estudio: Astrophytum ornatum (Cactaceae). Sitio de estudio y fechas: Observaciones de 2010 a 2011 en la población más densa de A. ornatum en la Barranca de Metztitlán (Hgo. México). Métodos: Censos mensuales y seguimiento de estructuras reproductivas. Seguimiento de flores en antesis. Polinizaciones controladas para determinar el sistema de cruza y determinación del índice de entrecruza de Cruden (OCI) y de la relación polen/óvulo para estimar el sistema de apareamiento. Resultados: Astrophytum ornatum produjo botones florales todo el año pero el 89.2% de ellos fueron abortados. Se presentaron cuatro eventos efímeros de floración poblacional/año. La especie es autoincompatible y las polinizaciones controladas indicaron escasez de polinizadores (abejas). La especie es xenógama facultativa según el OCI o xenógama obligada por la relación polen/óvulo. En promedio se producen 54 semillas/fruto y 4 frutos/individuo/año. Conclusiones: La producción continua de botones florales es un fenómeno raramente reportado para cactáceas. La floración intrapoblacional constituye uno de los registros más cortos para la familia y produce una alta sincronía floral. El bajo número de semillas/fruto y de flores/individuo, aunado a la amplitud restringida del nicho de la especie y a diversos factores antropogénicos sitúan a Astrophytum ornatum como especie susceptible de extinción.

Premise: Divergence of floral morphology and breeding systems are often expected to be linked to angiosperm diversification and environmental niche divergence. However, available evidence for such relationships is not generalizable due to different taxonomic, geographical and time scales. The Palearctic genus Helianthemum shows the highest diversity of the family Cistaceae in terms of breeding systems, floral traits, and environmental conditions as a result of three recent evolutionary radiations since the Late Miocene. Here, we investigated the tempo and mode of evolution of floral morphology in the genus and its link with species diversification and environmental niche divergence. Methods: We quantified 18 floral traits from 83 taxa and applied phylogenetic comparative methods using a robust phylogenetic framework based on genotypingby-sequencing data. Results: We found three different floral morphologies, putatively related to three different breeding systems: type I, characterized by small flowers without herkogamy and low pollen to ovule ratio; type II, represented by large flowers with approach herkogamy and intermediate pollen to ovule ratio; and type III, featured by small flowers with reverse herkogamy and the highest pollen to ovule ratio. Each morphology has been highly conserved across each radiation and has evolved independently of species diversification and ecological niche divergence. Conclusions: The combined results of trait, niche, and species diversification ultimately recovered a pattern of potentially non-adaptive radiations in Helianthemum and highlight the idea that evolutionary radiations can be decoupled from floral morphology evolution even in lineages that diversified in heterogeneous environments as the Mediterranean Basin.

Is self‐incompatibility a reproductive barrier for hybridization in a sympatric species?

PremiseBarriers at different reproductive stages contribute to reproductive isolation. Self‐incompatibility (SI) systems that prevent self‐pollination could also act to control interspecific pollination and contribute to reproductive isolation, preventing hybridization. Here we evaluated whether SI contributes to reproductive isolation among four co‐occurring Opuntia species that flower at similar times and may hybridize with each other.MethodsWe assessed whether Opuntia cantabrigiensis, O. robusta, O. streptacantha, and O. tomentosa, were self‐compatible and formed hybrid seeds in five manipulation treatments to achieve self‐pollination, intraspecific cross‐pollination, open pollination (control), interspecific crosses or apomixis, then recorded flowering phenology and synchrony.ResultsAll species flowered in the spring with a degree of synchrony, so that two pairs of species were predisposed to interspecific pollination (O. cantabrigiensis with O. robusta, O. streptacantha with O. tomentosa). All species had distinct reproductive systems: Opuntia cantabrigiensis is self‐incompatible and did not produce hybrid seeds as an interspecific pollen recipient; O. robusta is a dioecious species, which formed a low proportion of hybrid seeds; O. streptacantha and O. tomentosa are self‐compatible and produced hybrid seeds.ConclusionsOpuntia cantabrigiensis had a strong pollen–pistil barrier, likely due to its self‐incompatibility. Opuntia robusta, the dioecious species, is an obligate outcrosser and probably partially lost its ability to prevent interspecific pollen germination. Given that the self‐compatible species can set hybrid seeds, we conclude that pollen–pistil interaction and high flowering synchrony represent weak barriers; whether reproductive isolation occurs later in their life cycle (e.g., germination or seedling survival) needs to be determined.
