Anatomía y morfogénesis de las agallas producidas por leptocybe invasa en plantas de eucalyptus
(Sociedad Argentina de Botánica, 2015)
Leptocybe invasa o “avispa de la agalla del eucalipto”, es un microhimenóptero gallícola que
ovipone en hojas jóvenes de eucaliptos. La planta responde formando agallas, que causan enrollamiento,
defoliación y colapso ...
Floral structure, development of the gynoecium, and embryology in schinopsis balansae engler (anacardiaceae) with particular reference to aporogamy
(University Of Chicago Press, 2016-04)
Premise of research. Most studies of Anacardiaceae embryology have focused on seed and fruit development in different genera. None of them, however, included species of Schinopsis. Considering the absence of embryological ...
Ontogenia del óvulo y semilla de sterculia striata (sterculiaceae)Ovule and seed ontogeny of sterculia striata (sterculiaceae)
(Instituto de Botánica del Nordeste, 2006-01-01)
Sterculia striata presenta flores estaminadas y perfectas que son funcionalmente pistiladas en un mismo pie, por lo que esta especie se describió como andromonoica. El ovario es apocárpico, constituido por 4-5 carpelos, ...

Structure of staminate flowers, microsporogenesis, and microgametogenesis in helosis cayennensis var. cayennensis (balanophoraceae)
(Consejo Superior de Investigaciones Científicas. Real Jardín Botánico, 2013-07)
Se analizó la estructura de las flores masculinas de Helosis cayennensis (Sw.) Spreng. var. cayennensis con microscopía óptica y electrónica de barrido y se estudió la microesporogénesis y la microgametogénesis. Las flores ...
Sugary secretions of wasp galls : a want-to-be extrafloral nectar?
(Oxford University Press, 2017)
Background and Aims The most widespread form of protective mutualisms is represented by plants bearing
extrafloral nectaries (EFNs) that attract ants and other arthropods for indirect defence. Another, but less common,
form ...
Embryology in helosis cayennensis (Balanophoraceae) : structure of female flowers, fruit, endosperm and embryo
(MDPI, 2019)
Helosis cayennensis (Balanophoraceae s.str.) is a holoparasite characterised by aberrant
vegetative bodies and tiny, reduced unisexual flowers. Here, we analysed the development of female
flowers to elucidate their ...
Lectotypification, geographic distribution and conservation status of Cephalanthus glabratus (Naucleeae-Rubiaceae)
(Instituto de Pesquisas Jardim Botânico do Rio de Janeiro, 2021)
Cephalanthus glabratus is an imperfectly known species of the family Rubiaceae. It is a medicinal plant widely
used by the locals in its area of distribution, however until now it has received little attention from the ...
Phylogenetic relationships within turneraceae based on morphological characters with emphasis on seed micromorphology
(Springer Nature, 2015-03-31)
Genera of Turneraceae differ notably in connation/adnation of calyx, corolla, and androecium. Floral and seed morphology were analyzed in all genera. Phylogenetic analyses were made using a matrix of 91 characters coded ...
