Salvia semiscaposa (Lamiaceae) a new species from Nanchititla, Mexico

Abstract

A new species of Salvia section Lavanduloideae from the Estado de México is described and illustrated. Salvia semiscaposa is a procumbent plant morphologically similar to S. scaposa and S. helianthemifolia. It differs from the former by having mostly obovate leaf blades, more than six flowers per verticillaster and posterior calyx lobes narrower and apiculate. On the other hand, S. helianthemifolia differs from the new species by the presence of an erect stem, ovate leaves and trichomes on the calyx surface distributed only on the veins. ResumenSe describe e ilustra una nueva especie de Salvia sección Lavanduloideae del Estado de México. Salvia semiscaposa es una planta procumbente morfológicamente similar a S. scaposa y S. helianthemifolia. De la primera difiere por presentar generalmente hojas obovadas, más de seis flores por verticilastro y lóbulos posteriores del cáliz más estrechos y apiculados. Por otro lado, S. helianthemifolia difiere de la especie nueva por la presencia de un tallo erecto, hojas ovadas y tricomas del cáliz presentes solamente en las venas.

Hiding in the Atlantic Forest: Leaf geometric morphometrics redefines endangered Aristolochia (Aristolochiaceae) sibling species and allows conservation strategies

“…Plant morphometrics allows the assessment of pattern variation at low cost, provides consistent results, and helps solving taxonomic uncertainties at both species and population levels (Marhold 2011;Turco et al 2022). Geometric Morphometrics (GM) has been applied to assess leaf (Cheng et al 2021;Danila & Alejandro 2021;Guamba et al 2021) and/or flower quantitative variation to distinguish species (Fragoso-Martínez et al 2015;Menini-Neto et al 2019;Freitas et al 2020b;Guamba et al 2021;Pessoa et al 2020;Araújo et al 2023), by identifying homologous points across samples, called landmarks, and comparing the format of each one of the structures in its entirety (Christodoulou et al 2020). Linear morphometrics, on the other hand, uses only measurable values, such as length and width, not considering the shape (Christodoulou et al 2020).…”

Unraveling the extreme morphological variation in the neotropical Ficus aurea complex (subg. Spherosuke, sect. Americanae, Moraceae)

“…Morphometric analyses can be part of an integrative taxonomy approach as they allow quantifying variation in plant structures (Zelditch et al, 2004). These methods have been used in different studies to solve taxonomical controversies in distinct angiosperm groups (e.g., González‐Rodríguez & Oyama, 2005; Castello & Galetto, 2013; Fragoso‐Martínez et al, 2015; Piedra‐Malagón et al, 2016).…”

A new species of Salvia from the Fulgentes clade (Lamiaceae), from Puebla, Mexico

“…As a result, the country is considered the main center of diversification for the genus in the New World (Ramamoorthy & Elliot 1998;Jenks et al 2013). In the last five years, at least 16 new species of Salvia have been described in different regions of the country (Bedolla-García & Zamudio 2015, 2018Fragoso-Martínez et al 2015;González-Gallegos 2015;González-Gallegos & Castro-Castro 2016;González-Gallegos & López-Enríquez 2016;González-Gallegos et al 2018;Martínez-Gordillo et al 2016a, 2016b, demonstrating that there is still taxonomic work regarding the genus, that needs to be done in Mexico.…”
