Three new species of Ocotea (Lauraceae) from Brazilian Atlantic forest

Abstract

ABSTRACT(Three new species of Ocotea (Lauraceae) from Brazilian Atlantic forest) Three new species of Ocotea -O.

Leaf venation ofOcoteaspecies (Lauraceae) from the Reserva Natural Vale, Linhares, Espírito Santo, Brazil

“…Specimens of O. lobbii from RNV match the former ones. For O. marcescens , specimens from RNV partially agree with the description given by Assis and Mello‐Silva (2009), who recorded 7–11 secondary veins per side of the lamina, angled 45–60(–80) degrees to the midvein, and areoles medium to large sized (0.5–1.7 mm diam. ).…”

“…Specimens of O. ciliata from RNV agree with those described by Assis and Mello‐Silva (2009), based on three collections from RNV (paratypes) and the holotype collected in Guarapari, Espírito Santo, as possessing 10–13 secondary veins per side of the lamina, and medium sized areoles. For O. divaricata , available information sources are: Coe‐Teixeira (1980): 3–4 pairs; Quinet and Andreata (2002): venation eucamptodromous, 3–4 pairs diverging at 35–55 degrees to the midvein; Baitello and Marcovino (2003): 3–5 pairs; Assis et al (2005): brochidodromous, 3–6 pairs; and Barbosa et al (2012): eucamptodromous, 3–5 pairs, coarse.…”

Two New Species of Ocotea (Lauraceae) from the Brazilian Restinga

“…The new species Ocotea arenicola is included in the O. indecora (Schott) Mez group, which, under a wider circumscription than Rohwer's (1986; see also Assis et al, 2005), encompasses 20 species and is defined by the rhythmic growth of the branchlets, the only morphological synapomorphy inferred (Assis, 2009;Assis & Mello-Silva, 2009, 2010. Among these species, it most resembles O. lobbii (Meisn.)…”

“…Ocotea ramosissima is included in the O. indecora group (Assis, 2009) on the basis of the rhythmic growth of the branchlets. Within that group, this new species resembles O. fasciculata (Nees) Mez, a widespread species from Amazonia to eastern Brazil and Bolivia that is found in forests, restinga, and campos rupestre vegetation.…”

A synopsis of Ocotea (Lauraceae) from the Reserva Natural Vale, Linhares, Espírito Santo, Brazil

“…Tall trees up to 26 m high, monoecious (flowers bisexual), leaves elliptical to ovate, 5.1–9.1 × 1.7–3.7 cm, base obtuse to rounded (Figure ), without domatia, tepals sparsely to densely pubescent on the abaxial surface, sparsely to densely papillose on the adaxial surface (Figure ), the bracts of the coflorescences foliaceous to scale‐like, fruits ellipsoid to ovoid, 1.5–1.8 × 0.7–1.0 cm, cupules with double‐margin bearing the persistent and revolute tepals (Assis and Mello‐Silva, ) (Figure ).…”
