“…A few other Neotropical species of Habenaria, such as H. cryptophila, H. curvilabria, H. distans, H. glaucophylla, and H. yookuaaensis Mejía-Marín, Espejo, López-Ferr. & R. Jiménez also occur in karst (Warming 1908;Bianchetti et al 2005;Mejía-Marín et al 2017). However, they are rainforest species not exclusive to karsts, and most have a wide distribution.…”

Habenaria karstica J.A.N.Bat. sp. nov., a new species from limestone outcrops (i.e., karst) in the State of Minas Gerais, Brazil, is described. The new species is ecologically very distinct since it is the only Neotropical species of the genus that grows on limestone outcrops under full sun, associated with mat-forming saxicolous plants. It is morphologically similar to species of the Habenaria repens complex, and separation is only possible through a combination of morphological characters. Bayesian and parsimony phylogenetic analyses based on nuclear (rDNA ITS, ETS) and plastid (matK-trnK, rps16-trnK) DNA markers revealed that H. karstica belongs to H. sect. Spathaceae. The new species, however, differs in floral morphology from the other species in this clade. A survey of the literature and public plants datasets revealed 122 species and 58 genera of Orchidaceae in karsts of Brazil. Although small compared to the family’s diversity in the country, Orchidaceae is among the families with the highest number of species in some karst localities. Our results indicate that approximately 97% of Orchidaceae found in karsts of Brazil is not limited to limestone outcrops areas, and that species composition of each locality is primarily determined by the regional flora and the biome in which it is located.

“…Para el distrito de Pochutla Castillo-Campos et al (1997) estudiaron la flora de las bahías de Huatulco, registrando 413 especies, 272 géneros y 78 familias; Domínguez-Licona et al (2008) inventariaron la flora de la microcuenca del río Cacaluta en el municipio de Santa María Huatulco, registrando 145 especies agrupadas en 131 géneros y 55 familias de plantas vasculares; Espejo-Serna y López-Ferrari (2009) describieron una nueva especie de la familia Bromeliaceae para el distrito de Pochutla; Salas-Morales (2004) publicó un nuevo registro para Oaxaca de una especie de la familia Tiliaceae, de la cuenca del río Zimatlán; Salas-Morales et al (2003) elaboraron una lista florística de la región de Zimatlán, la cual pertenece a los distritos de Pochutla y Tehuantepec; Salas-Morales et al (2007) integraron una lista de las plantas vasculares del parque nacional Huatulco; Soto-Arenas (2003) describió una nueva especie de la familia Orchidaceae endémica de Oaxaca y que es conocida de la planicie costera del Pacífico y de las faldas de la Sierra Madre del Sur. Entre los trabajos representativos para el distrito de Jamiltepec están los de Mejía-Marín (2014) quien realizó el primer listado florístico de las monocotiledóneas del municipio de San Juan Colorado; posteriormente, Mejía-Marín et al (2016) publicaron un listado integral de las monocotiledóneas del mismo municipio, registrando 23 familias, 81 géneros y 139 especies; Mejía-Marín et al (2017) publicaron una nueva especie de la familia Orchidaceae de la zona; Mendoza-Ruiz et al (2017) elaboraron un listado florístico de los licopodios y helechos que habitan en el municipio; Mejía-Marín et al (2020) publicaron una nueva especie de la familia Bromeliaceae.…”

The plant diversity has been and is the main theme of very diverse and different projects due to the need to know and use plant resources in a sustainable way; several factors have been identified that threaten this diversity, such as: the destruction of habitats, environmental pollution, overexploitation of resources, the introduction of exotic species and climate change. Although many and very diverse studies have been carried out on the diversity and vegetation of the country, the biodiversity of many regions and of various groups of plants is still unknown; as are the phanerogams of Oaxaca, which constitute 89.4% of the 255 families reported for the country (Espejo-Serna et al., 2004;Villaseñor, 2004). The 1841 genera represent 69% of the 2677 ocurrung in Mexico and the 8228 species in the state represent 37.3% of the 22397 in the country (Villaseñor, 2004), which shows the great diversity present in the state of Oaxaca. García-Mendoza ( 2004) reported for the state 223 families, 1712 genera and 7804 species of phanerogams, being the angiosperms, the best represented with 217 families, 1700 genera and 7752 species. In an update of these data, García-Mendoza & Meave (2011) reported 228 families, 1841 genera and 8228 species, of which 667 are endemic to Oaxaca. In Villaseñor (2016), 226 families, 1783 genera and 9411 species were reported. The importance of documenting the plant richness in many places is, therefore, cannot be postponed, if we also consider the accelerated destruction of ecosystems and the incomplete knowledge of their components. That is why the objective of this work was to develop an inventory of the phanerogamic flora of the municipality of San Juan Colorado, district of Jamiltepec, located in the south-western part of the state of Oaxaca.Between 2014 and 2017, several botanical collection trips were made to various locations in the municipality, giving preference to the best-preserved areas.Likewise, the specimens deposited in the ENCB, MEXU and UAMIZ herbaria were reviewed to detect the material from the study area. To identify or collate the determination of the specimens, specialized literature was used in each of the study groups. The supporting material collected during the study was deposited in the Herbario Metropolitano (UAMIZ) and duplicates were distributed to institutions in the pedicelo, sobrepuesto, con 2 lóculos, polen con dos alas prominentes como sacos en cada grano; megastrobilos (conillos) en grupos pequeños en el ápice de las ramas, escamas ovulíferas numerosas, leñosas, abiertas en corto período para recibir el polen y cerradas inmediatamente después de la polinización; óvulos 2 por escama. Fruto un cono, simétrico u oblicuo, con numerosas escamas abiertas o cerradas, el umbo dorsal o terminal a la escama variable en grosor, con una cúspide que termina en una espina aguda o gancho, persistente o decidua; semillas similares a nueces, aladas o sin ala, testa suave o endurecida.Género con cerca de 94 especies, para México se han citado 47 especies,

The genus Habenaria Willdenow (1805: 5,44) is one of the most diverse and most complex genus in the Orchidaceae, with approximately 800 species. It has a Pantropical geographical distribution. (Ames 1910, Williams 1951, McVaugh 1985, González 1993, and Batista et al. 2011a, 2011b). Recently Habenaria luquanensis G.W.Hu in Long et al. (2015: 190) was described from China, H. fimbriatiloba (Kolanowska 2016: 96) from Nepal and H. reflexicalcar J.A.N.Bat. & B.M.Carvalho in Batista et al. (2016: 278), H. hippocrepica J.A.N.Bat & Bianch in Batista et al. (2016: 282), H. quadriferricola J.A.N.Bat. & B.M.Carvalho in Batista et al. (2016: 286) and H. espinhacensis J.A.N. Bat. & A.A.Vale from Brazil in Batista et al. (2016: 288). However, a new species has been discovered recently, H. yookuaaensis Mejía-Marín, Espejo, López-Ferr. & R.Jiménez in Mejía-Marín et al. (2017: 74) increasing the number of known taxa in Mexico.
