“…El trabajo de Nickrent et al (2004) provee el primer panorama general de la relaciones de este grupo de parásitos y muestra que los integrantes de la familia Cytinaceae, antes la tribu Cytineae, se encuentran relacionados con taxones del orden Malvales, donde potencialmente están vinculados con otro conjunto también segregado de Rafflesiaceae (la familia Apodanthaceae), aunque las conexiones entre ambos grupos y la posición relativa de éstos aún no están resueltos (Nickrent et al, 2004). La evidencia recientemente obtenida coloca a Cytinaceae como hermano de la familia Muntingiaceae, que junto con miembros de Thymelaeaceae forman el grupo hermano del orden Malvales s. l. (Nickrent, 2007). Los restantes géneros de Rafflesiaceae (Rafflesia R.…”

“…Aunque ya existen trabajos que tratan a las tribus de Rafflesiaceae como cuatro entidades distintas (Stevens, 2001;Burgoyne, 2006;Nickrent, 2007), en esta aportación se considera conveniente proporcionar una descripción de la familia Cytinaceae junto con los taxones aquí abordados. Plantas holoparásitas, dioicas, monoicas o rara vez polígamo-monoicas, aclorófilas.…”

“…La cercana relación entre Cytinus y Bdallophytum fue reconocida desde el siglo XIX (Brown, 1844; Solms-Laubach, 1889); este supuesto no ha cambiado desde entonces y la hermandad entre estos taxones se ha corroborado con datos morfológicos y moleculares (Kuijt, 1969;Takhtajan, 1997;Bouman y Meijer, 1994;Nickrent et al, 2004;Nickrent, 2007 Parásitas dioicas o polígamo-monoicas con ejes florales bien desarrollados, carnosos, no ramificados, de color guinda a morado, esparcida a densamente pubescente-glandulares, lo que les da una coloración pardo-amarillenta. Inflorescencia espiciforme.…”

En México se presentan todas sus especies, dos de las cuales son endémicas. Anteriormente se le ubicaba en la tribu Cytineae de la familia Rafflesiaceae, pero según los estudios filogenéticos basados en datos moleculares, este grupo se reconoce ahora a nivel de familia como Cytinaceae. En su historia se han reconocido para Bdallophytum de uno a cuatro componentes y la última revisión taxonómica para el género fue realizada hace más de 70 años. El presente trabajo se apoya en un análisis de coordenadas principales para evaluar la identidad y número de miembros que lo integran, reconociéndose tres especies. Se proporciona una clave de su identificación, así como datos bibliográficos, descripciones morfológicas, enumeración de los ejemplares estudiados, información ecológica, mapas de distribución y fotografías.Palabras clave: Bdallophytum, Cytinaceae, México, neotrópico, plantas parásitas. ABSTRACTThe genus Bdallophytum is comprised of root parasitic plants distributed in northern neotropics. In Mexico occur all the species of the genus, two of which are endemic. The genus has previously been positioned within the tribe Cytineae of the Rafflesiaceae, but based on results from molecular phylogenetic analyses, this tribe is currently recognized at the rank of family as Cytinaceae. Historically, one to four species have been accepted in the genus, and the most-recent taxonomic treatment for the genus was realized more than 70 years ago. In the present work, a principal coordinate analysis was conducted in order to evaluate the identity and number of species in this genus. The results of this analysis suggest

“…Many parasitic plants have been difficult to place in classification systems due to their highly modified or reduced morphology, and the advent of molecular systematics has resolved many of the mysteries associated with them; most are now placed to family and order (see APG II, 2003; APG III, 2009; Nickrent, 2009a). The lack of distinguishing morphological characters in many parasitic plants has often resulted in them being placed together in classification systems, and one of the major changes due to the molecular data has been the dismemberment of the order Rafflesiales (Nickrent et al , 2004; Nickrent, 2007). Molecular studies have, however, been hampered in many cases because the genes in the plastid (or chloroplast) genome, some of which are involved in photosynthesis, have often been lost or substantially altered in these parasitic plants (e.g.…”

Plants that parasitise other plants have been among the most difficult plant groups to fit into classification systems due to their modified biology and their often highly reduced morphology. They are now considered to be found in about 16 families of flowering plants. Here we summarise current ideas about their relationships and provide information about their characteristics and utilisation. A major consequence of the revised classification of Orobanchaceae and related families has been the break-up of the traditional Scrophulariaceae, and here we summarise the new classification, focusing on genera of horticultural interest.

Striking developmental convergence in angiosperm endoparasites

Plant parasitism has evolved 12 times within flowering plants (Nickrent, 2020). This phylogenetic diversity is accompanied by a wide variety of habits, geographical distribution, host preferences, morphologies, and developmental patterns (Kuijt, 1969;Heide-Jørgensen, 2008). A broad spectrum of photosynthetic capabilities is also represented among these plants, ranging from species fully capable of photosynthesis, to those that are achlorophyllous during all or most of their life cycle, thus rendering them entirely reliant on host resources (Bromham et al., 2013). A subset of plants in the latter category exhibits a particularly extreme degree of reduction: their vegetative body is reduced to mycelium-like filaments of parenchyma cells embedded within their host tissues. In these cases, the parasite only becomes visible during reproduction when the flower/inflorescence temporarily emerges from its host (Mauseth, 1990;Meijer and Veldkamp, 1993;Nikolov et al., 2014b). Due to this extremely reduced growth form, restricted to life inside its host, these plants are commonly referred to as endoparasites.This highly modified and cryptic growth habit has been best described in detail from a small number of mistletoe species (Těšitel, 2016). Mistletoes are widely distributed parasitic plants known as keystone species in both natural and human-altered ecosystems (
