“…Distribution, ecology and conservation status: Vanilla palmarum is widely distributed in South America, occurring in Bolivia, Brazil, Guyana, Peru, Surinam, and Venezuela (Soto Arenas & Cribb 2010). In Brazil, it occurs in the Amazon, Atlantic Forest, Caatinga and Cerrado, in the north, northeast and central-west regions (Barbarena et al 2019). In the study area it was found in tabuleiro forests in Paraíba, inhabiting the culm of Elaeis guineenses Jacq., an invasive palm, popularly known as Dendê (Moreira et Warmingia Rchb.f., Otia Bot.…”

Lowland forests, also known as tabuleiro forests, are the predominant phytophysiognomy in the Atlantic Coastal Forest in northeastern Brazil. We inventoried the Orchidaceae present in the northern section of those forests, from the state of Rio Grande do Norte until the southern region of the state of Pernambuco. We examined specimens from seven regional herbaria and undertook field expeditions to four conservation units in the region. A total of 65 species belonging to 36 genera and to subfamilies Epidendroideae (44 species), Orchidoideae ( 16), and Vanilloideae (5) were identified. The most diverse genera are Epidendrum e Habenaria, with eight and seven species, respectively. Native species represented 96 % of the total observed, with 27 % being endemic to Brazil. Epiphytic (35) and terrestrial (27) species predominated; only three species are hemiepiphytic. We registered 14 new records of species for Rio Grande do Norte, two for Paraíba, and one for Pernambuco. Diagnoses of genera and species, as well as an identification key, data on geographic distribution, taxonomic and ecological comments, conservation status, and photos of the species are provided.

“…However, some can be found in uncommon habitats like marshy forests (e.g., V. arcuata and V. paludosa [30]). While most species can climb to various substrates (trees and rocks), an epiphytic Vanilla (V. palmarum) is exclusively associated with nine species of palms in South America [31]. Some species can be found in different types of ecosystems like V. inornata [32].…”

The Leafless Vanilla Species-Complex from the South-West Indian Ocean Region: A Taxonomic Puzzle and a Model for Orchid Evolution and Conservation Research

et al. 2020

The pantropical genus Vanilla is a member of the Orchidaceae family, one of the largest and most diverse families of angiosperms in the world. It originated in America and differentiated in America, Africa, and Asia. About 132 species of Vanilla have now been accepted since the discovery of the genus. Within the Vanilla genus, leaflessness has appeared at least three independent times, in Africa, Asia, and America as an adaptation to drought conditions. The South-West Indian Ocean (SWIO) region, a biodiversity hotspot for orchids, is home to seven leafless species. Chloroplast markers failed to differentiate species within this recent SWIO clade. Morphological traits used for description are very similar between species and do not provide reliable identification. Moreover, some of the species have overlapping flowering periods and geographic distribution in Madagascar, increasing the probability of finding some sympatric species and, therefore, hybrids. Leafless Vanilla species from the SWIO islands are thus an excellent model for understanding the evolution of orchids. For their conservation, and to confirm the identity of these leafless species, an integrated approach with classical taxonomy using a large number of samples, intense fieldwork on biology and ecology, and molecular studies using variable markers is necessary.

“…Orchidaceaeapart from a few truly epiphytic species (e.g. Vanilla palmarum, Barberena et al 2019) and a self-supporting terrestrial (Pansarin 2010), members of this genus are usually climbing plants. These are often described as "hemiepiphytes" (without qualifier) (e.g.…”

Do secondary hemiepiphytes exist?

et al. 2021

View full text Add to dashboard Cite

For decades, tropical ecologists distinguished primary (PH) and secondary hemiepiphytes (SH) as two structurally dependent life forms with an epiphytic phase at, respectively, the beginning or the end of their ontogeny. However, the use of these terms has been criticized repeatedly because the term “hemiepiphyte” suggests an unsubstantiated biological similarity in ontogeny, and worse, because it is often used without a qualifier, which makes unambiguous interpretation of the life history of such species impossible. In this paper, we go one step further and ask the question whether an ontogenetic trajectory as described by the term “secondary hemiepiphyte” does exist at all. We show that until now all evidence available for the three families that were traditionally listed as taxa with SHs (Araceae, Cyclanthaceae, Marcgraviaceae) falsifies such claims, but critically discuss reports of possible SHs in other families. In all these cases unambiguous conclusions about the existence of any SH are difficult, but our detailed discussion of potential candidates is meant to provide the basis for focused field studies. Irrespective of the outcome of these studies, we urge researchers to abandon the use of the term SH for the time being: Terminological issues can be discussed once there are data.
