“…The observations of this study confirm the conclusions of Cetzal-Ix et al (2014), on the need for further research regarding orchid fruits. Although the results of this work support the idea that fruit morphometrics and their images could help in the identification of the orchids shown, as suggested by Reyes-López et al (2014) and Rojas-García and Maldonado-Peralta (2021), when they are not in flowering season, it is necessary to expand the study of systematic botany of orchid species that includes the detailed description of the fruits.…”

The knowledge on Orchidaceae family fruits becomes useful in new studies, by helping to identify species that are not in flowering period and providing material for in vitro germination of orchid seeds. The hypothesis was that the number of orchid specimens with naturally pollinated fruits, from the central zone of the state of Veracruz, Mexico, would be more than the number of specimens that do not developed fruit naturally. The objectives of this work were: to record the flowering and fruiting periods, to characterize the orchid fruits pollinated naturally or manually. The fruit collection sites were located within the municipalities of Amatlán de los Reyes, Fortín and Tlaltetela. The work was performed between January 2019 and April 2022 (39 months). Ripe orchid fruits were collected. Morphometry was measured by recording weight (g), length (cm) and diameter of the central region (cm), complemented with a photographic record. The greatest fruit diversity of these orchids was observed and collected during the month of March. Forty-two species and their fruits were recorded, which were grouped into 8 subtribes and 32 genera. The genera with the highest number of species were: Epidendrum, Prosthechea and Oncidium, each with three species. Three species bloomed for 11 months: Platystele stenostachya, Specklinia digitale and S. tribuloides. The minor and major fruiting periods correspond to Specklinia digitale and Trichocentrum stramineum, respectively. Given the fact that in all three sites studied the greatest number of species and fruits is associated with natural pollination (27 species, 113 fruits), which exceeds the number of manually pollinated species (15 species, 51 fruits), it is possible to suggest that the largest contingent inhabits environments still compatible with the natural process of their reproduction in these sites.

“…Una forma para conservar la variabilidad genética del género Vanilla en México es mediante un banco de germoplasma, donde se resguardan in vivo cinco especies correspondientes a V. planifolia, V. pompona, V. inodora, V. insignis y V. odorata (Reyes-López, 2014, 2015; resta por encontrar las especies V. cribbiana y V. sprucei, que aun cuando se han visitado los lugares donde se reporta su existencia, no se ha logrado su rescate para su conservación; pero no se descarta su presencia, ya que aún no se han explorado totalmente los lugares donde posiblemente existan de manera silvestre.…”

Diversity and bioclimatic profiles of Vanilla spp. (Orchidaceae) in Mexico. The genus Vanilla comprises around 110 species distributed throughout Earth's tropical regions, with the largest number of reported species growing in the American continent. Vanilla farming is associated with many Mexican cultures such as the Totonac, Mayan, Chinantec, and Mazatec, among others. Currently, this crop is threatened by technical, social, ecological, and climatic conditioning factors, limiting its production and the preservation of wild and cultivated species. It is therefore necessary to ascertain the current diversity status of each of these species, as well as some of their main bioclimatic profile indicators, in order to help decision-making, aimed at preserving and genetically improve these species. During 2008, we gathered data from IPN, MEXU, and XAL herbaria, as well as from CONABIO's World Information Network on Biodiversity (REMIB), the Global Biodiversity and Information Facility (GBIF), and we also used data from live access to BUAP's vanilla germplasm bank, obtained between 2008 and 2014. Distribution maps were generated using a geographical information system. Bioclimatic profiles for each species were obtained considering 19 WorldClim variables and altitude at a spatial resolution of approximately 1 Km 2 . Variance, Mean, and standard deviation for each of the 19 variables were calculated at each of the registered points. Extreme environmental condition intervals (minimum, average, and maximum) were also obtained. In order to determine the most important distribution variables of the species, we performed a principal component analysis and carried out Kruskal-Wallis and Dunn's tests on the variables identified as significant. Results indicated records for V. planifolia, V. pompona, V. insignis, V. inodora V. odorata, V. cribbiana, and V. sprucei in Mexico, distributed throughout nine states in the country. V. planifolia presented wide intervals of temperature and rain precipitation, while V. pompona, V. odorata, V. insignis and V. inodora presented intermediate intervals. The amplitudes of extreme data for each species can be considered in locating areas where ex situ regional preservation strategies could be put in place, as well as in establishing areas for cultivation. The bioclimatic profile we found, allows for an indirect inference of each species' genetic condition, which could be used in genetic improvement programs; for instance, V. odorata grows at high altitudes and tolerates low temperatures, while V. inodora tolerates high temperatures, and V. odorata, V. pompona and V. planifolia tolerate low rain precipitation.

“…The plant samples used in this study were obtained from field surveys carried out in Costa Rica, Mexico and Guatemala, supplemented with lyophilized plant materials preserved in the Mexican National Collection (Reyes-López et al 2014), the BRC Vatel (Roux-Cuvelier & Grisoni 2010), and DNA from the herbarium of the Instituto Chinoin, AMO (Thiers continuously updated).…”
