... Tectaria recognized by . There is no modern revision of the New World species of Tectaria, and the taxonomy is still poorly understood, although there are regional works on the genus or descriptions of new species and hybrids (e.g., Moran 1990, 1992, 1995, Rojas-Alvarado 2001, 2004, 2006a, b, Rojas-Alvarado & Sanín 2014. ...
A new fern species, Tectaria moranii (sect. Tectaria; Tectariaceae), is described from central Costa Rica. Tectaria moranii is most similar to T. vivipara in having rachis bulbils, but the two are distinguishable by the habit of rhizome, shape of lamina, petiole and rachis color, proliferability of rachis bulbils, number of pairs of pinnae per lamina, pinna width, and sorus distribution. Tectaria moranii is assigned LC-Least Concern category following the IUCN guidelines.
... Ctenitis sotoana decribed by Rojas-Alvarado (2001) was based on collections from Costa Rica and Nicaragua. After examining images of holotype, paratype and sheets from Costa Rica and Nicaragua identified as C. sotoana, we concluded that it is not different from C. grisebachii. ...
Based on collections of 45 Herbaria in addition to newly collected specimens and some field observations, a taxonomic treatment for South American Ctenitis is provided, a hundred years after Christensen’s monographs. Guided by morphological species concept, 26 taxa are recognized (23 species and three varieties). A key including all taxa is provided, and all species are fully morphologically described, with information on distribution and habitat. Brazil is the richest country with 22 taxa, of which 13 are endemic, restricted mainly to Atlantic Forest. Taxa occurring in the other South American countries are also widely distributed in Mesoamerica and West Indies, except C. megalastriformis, only known from Peru, and C. refulgens var. peruviana, recorded in Peru and Bolivia. We dealt with 163 names that apply to the South American species. In addition, we propose three new combinations, and designate 38 lectotypes and three neotypes.
... The genus, and, in the Neotropics, especially the species centered around Tectaria incisa, are in need of detailed taxonomic study; not all Bolivian specimens can at present be reliably placed in the recognized species. In a series of papers on Tectaria in the Neotropics, primarily those occurring from areas in Costa rica to Peru, rojas-Alvarado has described nine new species, a new variety, as well as a new interspecific hybrid (involving T. lizarzaburui) in the genus (rojas-Alvarado 2001, 2004, 2006a, 2006b, rojas-Alvarado & Sanín 2014, and also cited new distributional records. In the most recent of these papers, the authors presented a key to the 28 species occurring in the area from Costa rica to Colombia. ...
We provide a synopsis to the family Tectariaceae in Bolivia, including 17 species in four genera. The main genus, Tectaria, has 12 species. Despite being one of the most common and conspicuous fern genera in humid lowland forests, it remains challenging, and further study will likely result in taxonomic changes for Bolivia.
... Even later, additional species were removed from Ctenitis and placed in other genera (Sundue et al. 2010, Zhang 2012). On the other hand, some new species and varieties have been described (Rosenstock 1915, Christensen 1936, Proctor 1958, Proctor 1965, Smith 1975, Stolze 1977, Sehnem 1979, Rojas 2001, Mickel & Smith 2004, Schwartsburd et al. 2007) and new combinations of neotropical Ctenitis have been published (Salino & Morais 2003) for taxa not included in Christensen's monographs (Christensen 1913(Christensen , 1920. Nevertheless, after analyzing numerous exsiccatae from European and North, Central and South American herbaria (see Methods), we believe there are ca. ...
We describe a new species and propose a new combination of Ctenitis from South America. The new species is from Peru. We named it Ctenitis megalastriformis due to the resemblance to Megalastrum. The new combination corresponds to the species known until now as C. pedicellata. This species should be called C. nervata, based on the older name Aspidium nervatum. Lectotypes are designated for A. pedicellatum and Dryopteris indecora, both considered here to be synonyms of C. nervata.
... Tectaria Cavanilles (1799: 109) is a large genus in ferns with extremely diverse morphology. The traditionally defined Tectaria is estimated to contain about 150 (Tryon & Tryon, 1982) to 210 species in pantropical areas (Holttum, 1991), of which about 50 in neotropics (Tryon & Tryon, 1982;Moran 1992, Rojas 2001, Smith 2006, Kessler & Smith 2007, Rojas & Sanín 2014, Riverón-Giró & Sánchez 2015. Molecular studies in recent years supported the monophyly of Tectaria in a broad sense which should include nearly all related satellite segregates with the basic number of chromosome being 40, such as Heterogonium C. Presl (1851: 142), Psomiocarpa C. Presl (1851: 161), Tectaridium Copeland (1926: 329) but excluding Hypoderris R. Brown ex Hooker (1838: t.1) (Ding et al., 2014;Moran et al., 2014;Wang et al., 2014). ...
A new natural hybrid, Tectaria × hongkongensis (Tectariaceae), is described and illustrated from Hong Kong, China. It is a sterile hybrid supported by the abortive spores and cytological data [2n = 120 (3x)]. This hybrid is morphologically somewhat similar to T. zeilanica in the small size of plants, strongly dimorphic leaves, the shape of sterile fronds, and acrostichoid sporangia. Molecular data indicate its maternal parent is probably T. harlandii. Tectaria × hongkongensis is the first hybrid confirmed by morphological and cytological evidence in East Asia.
... Even later, additional species were removed from Ctenitis and placed in other genera (Sundue et al. 2010, Zhang 2012).

Two new species of Ctenitis (Dryopteridaceae) from South America are described and illustrated: Ctenitis christensenii is endemic to southeastern Brazil and C. glandulosa occurs from southeastern to northeastern Brazil and in Guyana. An identification key and notes about the distribution, habitat and taxonomy of the new species, C. falciculata and allies are provided. Moreover, seven lectotypifications and two new synonyms are proposed.
... Se desarrolló un trabajo de campo durante dos expediciones: una a la Reserva Natural de la Sociedad Civil Riomanso en Colombia, al interior de una selva húmeda del Magdalena Medio de Caldas, y otra Al río Los Ahogados, en Santa Bárbara de Heredia, Costa Rica, en el reducto de bosque de la cuenca del río; donde, aparte de otras recolecciones, se halló material del género, cuyo estudio permitió el descubrimiento de las especies nuevas de Tectaria descritas aquí. La determinación de las especies y elaboración de la clave dicotómica se hicieron principalmente con base en los tratamientos de Flora Mesoamericana (Moran, 1995), los Pteridófitos de Colombia (Murillo & al., 2008) y las descripciones originales previas del primer autor (Rojas 2001(Rojas , 2006. Los especímenes fueron recolectados y preservados de acuerdo a la metodología establecida por Lorea y Riba (1990), y distribuidos a los herbarios: Museo Nacional de Costa Rica (CR), Universidad Nacional de Colombia (COL), Universidad de Caldas (FAUC), Universidad de Antioquia (HUA), Missouri Botanical Garden (MO) y Universidad de Costa Rica (USJ). ...
Las investigaciones en el género Tectaria Cav. para el Neotrópico han permitido
descubrir dos especies nuevas del complejo T. incisa Cav., que aquí
son descritas como T lacinifolia A. Rojas & D. Sanín y T. pardalina A. Rojas.
La primera especie difiere de T. incisa por presentar escamas del rizoma
ciliadas apicalmente, pinnas basales laciniadas basiscópicamente, pinna
terminal romboidal y con el margen laciniado. La segunda especie difiere
de Tectaria incisa por tener menos pares de pinnas, pinnas comúnmente
anchamente elípticas, tejido laminar dispersamente peloso abaxialmente,
soros en (2-) 3-5 series irregulares entre las nervaduras laterales y presente
a mayor elevación. Los especímenes fueron depositados en los herbarios
CR, COL, FAUC, HUA, MO y USJ.
... Los helechos y plantas afines han sido ampliamente estudiados en México y Centroamérica en obras recientes que cubren las regiones consideradas de mayor diversidad como el norte de México (Adams et al. 1993), noroccidente (Mickel 1998), Oaxaca (Mickel y Beitel 1982) y Mesoamérica (Moran 1995) y con estudios pteridoflorísticos regionales (Palacios 1992, Riba et al. 1996, Tejero y Arreguín 2002, Lorea y Velázquez 1998. Sin embargo, cotidianamente se descubren nuevas especies (Mickel y Smith 2000, Mickel 2001, Rojas 2001a, 2001b, 2001c, 2002a, 2002b, 2002c, Mendoza et al. 2001, Tejero y Pacheco 2002 que dan prueba de la vasta riqueza de especies que aún hace falta de descubrir en la región tropical de México y Centroamérica. Ahora, se describe en este trabajo a Dennstaedtia gracilis procedente de la región templada húmeda de la vertiente del Golfo de México, México. ...
... Smith & Moran (1987) recognized the genus and combined the remaining neotropical species. Kessler & Smith (2006) In the last decade only three species have been described in the Megalastrum biseriale group from the neotropics: M. ctenitoides A. Rojas (Rojas 2001), M. bolivianum M. Kessler & A.R. Sm. (Kessler and Smith 2006), and M. mollis A.R. Sm. (Smith 2006). Here six additional species are described as new. ...
... Also many species have included veinlets and others with divided blade have a basal basiscopic lobe or elongated pinnule (Moran 2000). Several new species has been described recently from the neotropics, between them: Tectaria estremerana (Proctor & Evans 1989); T. acerifolia (Moran 1990); T. pubens (Moran 1992); T. dariensis, T. longipinnata, T. murilloana, T. pascoensis and T. subdimorpha (Rojas 2001); T. x chaconiana (Rojas 2004) and T. dressleri (Rojas 2006 It is different from the typical variety because it has gemmae in the axils of terminal pinnae pairs and many times in costae of basal pinnae. In Costa Rica the new variety is restricted to Central Pacific area, and the typical variety is present in South Pacific and lowlands in the north and the Caribbean slopes of Costa Rica, both mutually exclusive in geographical distribution. ...
