Actinocephalus verae (Eriocaulaceae), a new species from the Brazilian Campos Rupestres
Brittonia, 2010We describe and illustrate the new species Actinocephalus verae (Eriocaulaceae: Paepalanthoideae). This species is endemic to the rocky outcrops of the Espinhaco range in Minas Gerais, Brazil. We make comparisons with Actinocephalus ithyphyllus and Actinocephalus ochrocephalus, the morphologically most similar species.

Abstract— A recent phylogenetic tree for the large paraphyletic genus Paepalanthus showed that the genus Actinocephalus is also paraphyletic with two species of Paepalanthus nested within it: Paepalanthus macrocephalus and Paepalanthus camptophyllus. These species have the diagnostic morphological traits of Actinocephalus, but they are too small to be

Morphological architecture of Actinocephalus (Koern.) Sano (Eriocaulaceae-Poales)
Flora - Morphology, Distribution, Functional Ecology of Plants, 2008Abstract Actinocephalus exhibits perhaps more diversity in habit than any other genus of Eriocaulaceae. This variation is largely a result of differences in the arrangement of the paraclades. Based on the analysis of stem architecture of all 25 species of Actinocephalus , the following patterns were established: (1) leaf rosette, with no elongated

Abstract: The embryology and seed structure of Paepalanthus sect. Actinocephalus species were studied. The embryological and structural seed characters fit well with those of the other commelinaceous families. Within the Commelinales sensu Dahlgren, Eriocaulaceae and Xyridaceae represent two embryologically close families.

Fenologia de Paepalanthus hilairei Koern., P. polyanthus (Bong.) Kunth e P. robustus Silveira: Paepalanthus sect. Actinocephalus Koern. - Eriocaulaceae [PDF]
Acta Botanica Brasilica, 1996 Foi realizado o acompanhamento fenológico de três espécies de Paepalanthus sect. Actinocephalus: P. hilairei, P. polyanthus e P. robustus. Realizaram-se viagens mensais à Serra do Cipó, Minas Gerais, Brasil, durante um período de 21 meses. Detectou-se que P. hilairei e P. robustus são perenes e P. polyanthus é bienal.

The genus Actinocephalus comprises 25 species and is restricted to Brazil, occurring mainly in the Espinhaço Mountains of Minas Gerais and Bahia States. Previous anatomical studies have reported the occurrence of intracellular papillae in the Actinocephalus roots, without dealing with their ultrastructure and function.

Abstract The life-history stages of two eugregarines, one biassociative the other solitary, were found in the larval mesenteron and proctodeum of the scarab Phyllophaga anxia LeConte. Only cysts of the solitary form were found in the adult mesenteron.

Revista CeresActinocephalus polyanthus (bong.) Sano (Eriocaulaceae) is an everlasting endemic endemic to Brazil with great potential for use in landscaping and as a cut flower on the national and international markets. In order to ensure that its use as an ornamental plant does not jeopardise populations of the species in areas of natural occurrence, as well as to ...
