The Sandpaper clade comprises a group of taxa endemic to the Greater Antilles and forms a subgroup of a larger Caribbean assemblage of Miconieae. Numerous species within this monophyletic group share striking morphological characters and thus traditionally have been considered close relatives. Recent phylogenetic work has shown that not all of these species are each other’s closest relatives, and they actually form three distinct clades: the Lima, Paralima, and Pseudolima clades. We reconstructed a phylogeny of these poorly known species to test patterns of morphological evolution and the biogeographic history of the clade. Methodology. We reconstructed a phylogeny of the Sandpaper clade using two plastid intergenic spacers (accD-psaI, psbK-psbL) and two nuclear ribosomal spacers (ITS, ETS) and then sequenced three more plastid spacers for the Lima clade (rpl32-trnL, trnV-ndhC, trnH-psbA) to provide better resolution among those species. The biogeographic history and the evolution of morphological traits were tested using maximum parsimony based on 12 mountain ranges in the Greater Antilles and 48 morphological characters, respectively. Pivotal results. The Sandpaper clade most likely originated in eastern Cuba, with subsequent dispersals to other parts of the island, as well as to Jamaica, Hispaniola, and Puerto Rico. In general, morphological characters shared by the Lima, Paralima, and Pseudolima clades evolved independently. All subclades of the Sandpaper clade can be recognized by suites of characters; however, unique synapomorphies for clades are rare. Conclusions. Eastern Cuba formed the starting point for the diversification of the Sandpaper clade, likely as a result of the diverse topography and associated ecological diversity (e.g., serpentine soils). This clade represents only a moderate-sized radiation of the Caribbean clade; however, the convergent nature of character evolution and the lack of unique synapomorphies for subclades underscore the lability of morphological characters in this group and the difficulty in recognizing these clades from a purely morphological standpoint. Keywords: Calycogonium, dispersion, endemism, Greater Antilles, Leandra, Ossaea.

This species can be easily assigned to Miconia section Chaenopleura due to its short anthers that open by two longitudinal slits. Sequence data from nrITS confirm this placement. This new species is characterized by its inconspicuous lepidote indumentum of minute adpressed scales ca. 0.05 mm long; small flowers in dichasia, forming a compact, many-flowered, rounded to subcorymbose cymes, with purple to fuchsia colored petals.

In this work, we give updated descriptions, nomenclatural information, geographic distributions, citation of all specimens examined, as well as habitat descriptions for each of the six species that occur on Cuba, five of which are endemic and one shared with Hispaniola. We also provide a key for all species of the section including the seven species endemic to Hispaniola. One new name, Miconia charleswrightii, and two new combinations are provided in Miconia, M. clementeana and M. heterophylla. Seven names are typified: Calycogonium heterophyllum Naudin, Calycogonium productum C. Wright, Clidemia barbeyana Cogn., Clidemia clementeana Britton, Clidemia wrightii Griseb., Melastoma calycopteris Rich. and Miconia pterosepala Urb.

Although this species has been known from sterile collections since the early 1980s, its phylogenetic position was unknown, although it was presumed to be closely related to species of Pachyanthus s. l. The phylogenetic reconstruction presented here, based on a recent collection of the species, clearly places M. cineana in a clade comprised of Cuban species of the polyphyletic genera Tetrazygia s. l. and Pachyanthus s. l. Thus, M. cineana represents the sole Hispaniolan member of an otherwise Cuban clade, and an uncommon biogeographic pattern in melastomes. Miconia cineana, although described here from sterile specimens, is easily distinguished from the other species of this clade using vegetative morphology, as well as phylogenetic placement. This study highlights the utility of molecular data when coupled with morphology, allowing for the discovery of an unrecognized species in a region of high diversity and endemism, i.e. the Massif de la Hotte.

A revised description of this species, including previously unknown floral characters, is presented, and the species is compared to M. remotiflora, also of the Sierra Maestra, and a putative close relative. The phylogenetic position of M. turquinensis within Miconia sect. Chaenopleura is confirmed morphologically, and M. remotiflora is placed in this section for the first time.

Lima is an entirely Greater Antillean clade that consists of 19 known species of shrubs and small trees, which were previously recognized under the polyphyletic genera Leandra and Ossaea. The highest species richness in the clade is represented on Cuba (10 species), followed by Hispaniola (8 species) and then Jamaica (1 species). Here we present a taxonomic revision of the clade based on the study of species in the field, herbarium specimens, as well as a DNA-based phylogeny reconstruction. The Lima clade most likely originated on Cuba and then spread to Jamaica once and Hispaniola multiple times. Species of this clade can be recognized by the well developed bulla-based hairs of the adaxial leaf surface, as well as the clavate-dendritic hairs produced along the primary, secondary and tertiary veins of the adaxial leaf surface, mostly towards the leaf base, terminal inflorescences, acute petal apices, slightly bulla-based hairs produced subapically along the petal abaxial surface, and anthers with a dorso-basal appendage and a single, dorsally oriented pore. Descriptions, synonymies, along with distribution maps and illustrations/ figures, are given for each species. Miconia pagnolensis sp. nov. is newly described in this revision.

The majority of these species belong to Calycogonium, a complex genus that has been shown to be polyphyletic, but for which we lack for many species any recent and suitable material for molecular systematics studies. A better understanding of homoplastic versus synapomorphic seed characters may therefore be helpful to illuminate the affinities of such species. Some taxa from Clidemia, Miconia, Ossaea, Pachyanthus and Tetrazygia were also sampled due to their morphological similarities with some species of Calycogonium. Variable seed characters include overall shape and size, raphe shape and size, and testa sculpturing. Based on these characters we grouped the species in five seed types, and an additional three species were found to have distinctive seeds that were not grouped with any other species. Species with identical seed types often belong to more than one genus as currently classified. There are five groups of species within Calycogonium characterized by similar seed morphology but none of the respective seed types is exclusive to the genus. Some of these seed types correlate well with previously proposed subgeneric groups of Calycogonium based on flower morphology and presences and type of leaf domatia. While the occurrence of some seed characters and states matches species groups in Calycogonium also found with molecular phylogenetic analyses, seed morphology generally indicates relationships of Calycogonium and allied taxa of the Caribbean clade that are not completely reflected by the current generic classification. The study provides a matrix for seed characters of the included species that will serve further phylogenetic reconstruction and analyses of character evolution.

The tribe is characterized by inflorescences that are terminal or axillary, but not cauliflorous (except a few species of Charianthus, Clidemia, and Mecranium), flowers subtended by only one pair of bracteoles (or none at all), with anthers that lack a pedoconnective, leaves without long acicular raphides, and berry fruits. Generic delimitations within the Miconieae have been notoriously complex, and phylogenetic analyses have shown that Miconia is paraphyletic with many other genera embedded within it.

Although this species has been known from sterile collections since the early 1980s, its phylogenetic position was unknown, although it was presumed to be closely related to species of Pachyanthus s. l. The phylogenetic reconstruction presented here, based on a recent collection of the species, clearly places M. cineana in a clade comprised of Cuban species of the polyphyletic genera Tetrazygia s. l. and Pachyanthus s. l. Thus, M. cineana represents the sole Hispaniolan member of an otherwise Cuban clade, and an uncommon biogeographic pattern in melastomes. Miconia cineana, although described here from sterile specimens, is easily distinguished from the other species of this clade using vegetative morphology, as well as phylogenetic placement. This study highlights the utility of molecular data when coupled with morphology, allowing for the discovery of an unrecognized species in a region of high diversity and endemism, i.e. the Massif de la Hotte.
