A valid name for the taxon known as Tillandsia bryoides auct. (Bromeliace-ae). Darwiniana 49(2): 131-138. Tillandsia bryoides was sunken into the synonmy of T. tricholepis because all the elements of the lectotype (P. Lorentz 128, BM) belong to the latter species. However, there are many vouchers from different herbaria (some of them cited as refer...

Bromeliads (Bromeliaceae) are an extremely diverse family of the angiosperms widely distributed in the tropical and subtropical regions of the Americas and West Africa. They often serve as phytotelmata, accumulating rainwater between leaves. Such water reservoirs can be inhabited by diverse organisms. But to date not much attention is paid to inven...

The knowledge of the diversity of species which integrate the goat’s diet is a strategic input to improve the productivity and sustainability of the range extensive systems of the Arid Chaco in the province of Catamarca. The diversity of native forage which is used by goats is studied in this work for a representative area on the second level of the low hill of the Arid Chaco, in the province of Catamarca. The study of the forage vascular flora was made on 145 ha without grasser animals and settled in the southeast of Capital County. It was used the classical methodology for de the systematic determination of the plants. The register of the forage plants and its parts eaten by goats was basically made on direct observations between the years 2008 to 2014 on the extensive grazing regions of La Paz, Valle Viejo, Capital, Capayán and Fray Mamerto Esquiú counties. It was consigned the scientific and common name, the botanical family, habit, status, and the part eaten by goats. It was founded that goats consumed 110 species (72 %) of the 152 total native vascular plants observed in this work. The high diversity of the forage species founded in the low hill botanical communities of the Arid Chaco shows the aptitude of these ecosystems for the development of a sustainability goat keeping.

... However, in a synopsis of fourteen species, Baker (1878) decided to treat Diaphoranthema as a subgenus within Tillandsia, and the taxon has remained within this genus and at the same rank ever since. During the last three decades, several new species have been described within Diaphoranthema, bringing the total number of recognized species to 29 Hromadnik 1983, 1984;Gouda 1986Gouda , 1988Hromadnik and Till 1991;Till 1992bTill , 1995Donadío 2011Donadío , 2013. ...
... Floral morphology is similar among species, by having narrow petals, included stamens, and a short, stout style (Smith and Downs 1977;Till 1984;Benzing 2000). Only the colour of flowers is highly variable (from white, green, to violet or black) and used to recognize a few species (Smith and Downs 1977;Till 1989bTill , 1991aTill , 1992aHromadnik and Till 1991;Donadío 2011Donadío , 2013. In addition, the group is also of evolutionary interest due to the presence of autogamous or even cleistogamous flowers (Billings 1904;Birge 1911;Gilmartin and Brown 1985;Till 1989aTill , 1992bKromer et al. 2006), and the presence of polyembryony, which, apart from Tillandsia juncea (Ruiz & Pav.)

Tillandsia subgenus Diaphoranthema (Tillandsioideae,
Bromeliaceae) includes 29 epiphytic species
distributed widely from southern North America to central
Argentina and Chile. The species of Diaphoranthema are
characterized by few small flowers, and most species are
differentiated by phyllotaxy, leaf shape, flower number,
and by the morphology and number of bracts. In addition to
the highly variable vegetative characters, most species of
subgenus Diaphoranthema possesses polyembryonic seeds
(rare in Bromeliaceae) and an autogamous breeding system
with a few number of species having cleistogamous flowers.
In order to clarify relationships within Diaphoranthema
and to understand the evolution of polyembryony, the
breeding system, and diagnostic characters, a cladistic
analysis of all known species using 85 morphological
characters was conducted. Phylogenetic results suggest that
Diaphoranthema is monophyletic if some species from the
closely related subgenus Phytarrhiza are included. These
two subgenera can only be distinguished from each other
by the shape and size of their petals. A complete sampling
of Phytarrhiza is still needed to test these hypotheses. None
of the six informal groups as previously recognized are
monophyletic. Vegetative characters such as phyllotaxy
and the shape, length, and width of leaves were the most
useful for distinguishing four major clades within Diaphoranthema.
Flower number, scape development, exocarp
and endocarp fusion at fruit ripening, and absence of
endosperm in mature seeds were also used to distinguish
some clades. Evolutionary trends favour a distichous
phyllotaxy, linear shape leaf blades, and a reduction in
flower number and bracts per inflorescence. In addition,
capsules with disaggregating exocarp and endocarp at
ripening, and polyembryonic seeds are also derived states
within subgenus Diaphoranthema.
Epiphytes make up roughly 10% of all vascular plant species globally and play important functional roles, especially in tropical forests. However, to date, there is no comprehensive list of vascular epiphyte species. Here, we present EpiList 1.0, the first global list of vascular epiphytes based on standardized definitions and taxonomy. We include obligate epiphytes, facultative epiphytes, and hemiepiphytes, as the latter share the vulnerable epiphytic stage as juveniles. Based on 978 references, the checklist includes >31,000 species of 79 plant families. Species names were standardized against World Flora Online for seed plants and against the World Ferns database for lycophytes and ferns. In cases of species missing from these databases, we used other databases (mostly World Checklist of Selected Plant Families). For all species, author names and IDs for World Flora Online entries are provided to facilitate the alignment with other plant databases, and to avoid ambiguities. EpiList 1.0 will be a rich source for synthetic studies in ecology, biogeography, and evolutionary biology as it offers, for the first time, a species‐level overview over all currently known vascular epiphytes. At the same time, the list represents work in progress: species descriptions of epiphytic taxa are ongoing and published life form information in floristic inventories and trait and distribution databases is often incomplete and sometimes even wrong. Since the epiphytic growth blends into soil‐rooted growth and vice versa, the inclusion or exclusion of particular species in the current list will sometimes be contentious. Thus, initiating a well‐founded discussion was one of the motivations for compiling this database; our list represents 31,311 hypotheses on the life form of plant species, and we welcome feedback on possible omission or erroneous inclusions. We release these data into the public domain under a Creative Commons Zero license waiver. When you use the data in your publication, we request that you cite this data paper. If EpiList 1.0 is a major part of the data analyzed in your study, you may consider inviting the EpiList 1.0 core team as collaborators.
