“…Here, it resembles V. taxifolia (Martius ex Schultes & Schultes 1829: 291) Martius ex Seubert (1847: 75) in its habit, but differs in the transverse posture of leaf blade, which is arcuate in V. everaldoi and flat in V. taxifolia. Moreover, the aquiferous hypodermis extending only to furrows is an anatomical character of V. everaldoi that is unique among all species of Vellozia thus far studied (Mello-Silva et al 2011). Its 12 stamens are distributed in the same manner as typical in the species with 12 stamens, e.g.…”

“…This feature together with spirotristichous phyllotaxis, a leaf blade that is involute when dry, hypanthial emergences absent to laxly disposed, and poricidal capsules support Vellozia sect. Xerophytoides (Mello-Silva et al 2011) and are all present in V. everaldoi, which is, then, expected to belong to that section. It has been collected with flowers in the cold, dry season, August and September.…”

“…Leaves spirotristichous, arcuate, sheaths brown, abundantly covered with orange resin, lamina 17.0-40.0 × 0.8-3.0 cm, linear-triangular, glabrous, marcescent and reflexed, margins serrate, midrib serrate towards apex at abaxial side. Flowers 3-6; peduncles 6-14 cm long, trigonous, subdensely covered with Notes on all new species:-A recent, more complete analysis of Velloziaceae (Mello-Silva et al 2011) permits some assumptions on the relationships of these new species in a phylogenetic framework. Vellozia giuliettiae and V. semirii share morphological characteristics that would assign them to V. sect.…”

“…Vellozia Vandelli (1788: 32) comprises a few more than 100 species endemic to the Neotropics, mostly in relatively dry, rocky or sandy habitats , Mello-Silva et al 2011. Following revision of Neotropical members of the family (Smith & Ayensu 1976), several new species have been described (Smith & Ayensu 1979, Smith 1985a,b, 1986, Menezes 1980a, Menezes & Semir 1991, Mello-Silva & Menezes 1988, 1999a,b, Mello-Silva 1991a, 1993, 1994, 1996, 1997, in press, Alves 1992, 2002, Alves et al 2014, Ibisch et al 2001, probably indicating a large number of species yet to be discovered.…”

Four new species of Vellozia are described and named after people linked to Velloziaceae and Brazilian botany. Vellozia everaldoi, V. giuliettiae, V. semirii and V. strangii are endemic to the Diamantina Plateau in Minas Gerais, Brazil. Vellozia giuliettiae and V. semirii are small species that share characteristics that would assign them to Vellozia sect. Xerophytoides, which include an ericoid habit with no leaf furrows and six stamens. Vellozia everaldoi, although a small, ericoid species, could not be placed in that section because it has conspicuous furrows, although it is considered closely related to species of that section. The fourth species, V. strangii, is a relative large species closely related to V. hatschbachii. Descriptions and illustrations of the species are followed by a discussion of their characteristics and putative relationships.

-(Velloziaceae from the Ibitipoca State Park, Minas Gerais, Brazil). A survey of Velloziaceae species from the Ibitipoca State Park is presented. The park is located in the Mantiqueira mountain range. Within the park there are several types of vegetation, mostly rocky fields, in which the species of Velloziaceae occur. The family has five genera and approximately 250 species. Two genera and four species occur in the park: Barbacenia flava, Vellozia albiflora, V. crinita and V. intermedia. Key for the genera and species, descriptions and illustrations are presented as well.

The monocot family Cyclanthaceae (Pandanales) comprises ca. 230 known species in 12 genera restricted to the Neotropics. The family has not been the subject of a species‐level molecular phylogenetic study to date, with multiple evolutionary and biogeographic questions about Cyclanthaceae still unanswered. In this study, we address genus‐ and species‐level relationships and the historical biogeography of Cyclanthaceae based on a broadly sampled molecular phylogeny. Two low‐copy nuclear genes (phyC, rpb2) and five plastid regions (atpB‐rbcL, psbA‐trnH, trnL‐trnF, trnQ‐rps16, matK) representing 99 species and all genera of Cyclanthaceae were sampled, spanning the taxonomic and biogeographic diversity of the family. Our results strongly support the monophyly of all Cyclanthaceae genera and confirm previously proposed hypotheses of intergeneric relationships. Infrageneric relationships are generally well supported, with some exceptions in the genus Asplundia that may require a broader sampling to clarify. The early diversification of Cyclanthaceae is estimated to date back to the Paleocene‐Eocene period in South America, where the family possibly arrived through a boreotropical route. The origin of most genera is inferred from the Paleocene of the Tumbes‐Chocó‐Magdalena region, possibly indicating an earlier origin for this biodiversity hotspot. The current distribution of Cyclanthaceae is likely to have been strongly influenced by major biogeographical events in the Neotropics, such as the uplift of the Andes and the opening of the South America dry diagonal. Further studies that include a broader sample of the large Asplundia‐Dicranopygium clade and Sphaeradenia group are required.
