Abstract

 Encyclia tuluaensis is a newly discovered orchid species, endemic to the tropical dry forests of Valle del Cauca, Colombia, a region characterized by high biodiversity and significant conservation relevance, primarily due to extensive habitat loss. This species was identified through comprehensive morphological analysis of cultivated specimens at the Juan María Céspedes Botanical Garden, in the municipality of Tuluá, Valle del Cauca. Initially, the species, which we hypothesize belongs to the Andean clade, was misidentified as Encyclia betancourtiana during the first collection due to its superficial similarity. However, detailed morphological analysis ultimately revealed significant differences, leading to its recognition as a new species. The species exhibits a range of distinctive floral and vegetative features, including three apical leaves, a pronounced fold in the central lobe of the lip, and marked color changes from anthesis to senescence. This discovery underscores the taxonomic complexity and biodiversity within the genus Encyclia, emphasizing the need for continued taxonomic and ecological research. Encyclia tuluaensis is part of the Andean species complex and is currently only known from its type locality. It requires particular conservation efforts due to its restricted distribution and the vulnerability of its habitat, which is threatened by deforestation, agricultural expansion, and urban development.

Lepanthes carrizosana is most similar to Lepanthes darioi Luer & R.Escobar. It can be distinguished by having a pubescent, obovate, bilaminate lip with cuneate connectives (vs. narrowly ovate lip and oblong connectives), and a small appendix with a pair of minute apical lobes that come from a slightly short pubescent, concave base (vs. broadly triangular appendix held directly below the stigma).

Eponymy: The name of the new species honors Julio Carrizosa Umaña, a scientist, environmentalist and thinker with a great vision of the connection between environmental institutionalism and strategies aimed at sustainable development in Colombia. He was the Director of the Institute of Environmental Studies of the National University of Colombia from 1993 to 1998. He currently coordinates the Natural Parks Committee of the Colombian Academy of Exact, Physical, and Natural Sciences. He has been designated a full member of the Colombian Society of Engineers, a full member of the Geographical Society of Colombia, vice president of the Colombian Society of Ecology in 1978, an honorary member of the Cartographic Society of Colombia and the Association of Fisheries Researchers, president of the Environment Committee of the Pan-American Institute of Geography and History between 1973 and 1976, and corresponding member of the Ecuadorian Institute of Natural Resources.

 DOI: 10.3100/hpib.v28iss2.2023.n3

 Abstract  

Comparative studies of macromorphological and palynological characters of plants representing Stenostephanus silvaticus from southern Mexico and southern Central America reveal that those from the two geographically isolated regions represent different taxa. Stenostephanus purpureus is described as a new species from Costa Rica and Panama. It differs from S. silvaticus of Chiapas, Oaxaca, Tabasco, and Veracruz, Mexico by numerous characters, including: pyramidal inflorescences with rachises, dichasial peduncles, and floral pedicels glabrous; corollas blue-purple to purple with both lips recoiled; and pollen subspheroidal with a fossulate interapertural band of exine bearing a medial row of gemmae and baculae. We provide a description of S. purpureus and a key to, images of, and map showing the distributions of both species.

in Marcano-Berti, Vélez-Puerta et Aymard-Corredor, 2023.

 HUH.harvard.edu 

  Researchgate.net/publication/371951503

Abstract

A new species of Vochysia, V. wilsonii (section Ciliantha, subsection Ferruginea), is described, and its morphological relationships with other similar Vochysia species are discussed. Vochysia wilsonii is found in wet forests over sandstone tabletop outcrops (“Mesetas”) and white sand soils in the Araracuara (“medio río Caquetá”) and Chiribiquete areas, a megadiverse region in the Colombian Guayana Shield, Caquetá department. This new species is a tree up to 25 m tall, and shares features with four species (Vochysia biloba, V. casiquiarensis, V. sabatieri, and V. vismiifolia). However, it differs in the size and shape of the leaves, stipules, inflorescence, cincinni, spur, spurred sepal, flower, central petal and stamen, as well as in its pubescence size and shape. An updated key of 45 Colombian species of Vochysia is provided.

Vochysia wilsonii Marc.-Berti, J.M. Vélez. & Aymard, sp. nov. 

 Vochysia wilsonii resembles V. biloba, V. casiquiarensis, V. sabatieri and V. vismiifolia, but can be differentiated from these species by having leaves obovate to obovateelliptic, 7.0–14.2 × 4.2–6.0 cm, apex emarginated, truncate to truncate-emarginate, short mucronate, base obtuse, lateral veins 24–29, at a 50˚– 60˚ angle with the midrib, stipules triangular, inflorescences 16–19 cm long, cincinni 3-flowered, rarely 2- or 4-flowered, spurred sepal 1.3–1.4 cm long, spur 6.5–7 mm long, subsigmoidal, and stamen glabrous dorsally, laxly pubescent on internal surface.

Etymology: Vochysia wilsonii is named after Wilson Rodríguez, a most enthusiast Colombian botanist, with an extraordinary knowledge of the floras of the Amazon and Orinoco river basins, of neotropical ferns, and, more recently, of Vochysiaceae.

 Common names: The name “Peraikz” (Uitoto) was recorded on the specimen Sastre & Raichel-Dolmatoff 4956.

Capparidastrum estrellae Cornejo & N. Mejía-Pazos, sp. nov.

Etymology: the epithet estrellae of this taxonomic novelty honors Dr. Eduardo Estrella Aguirre (1941–1996), an Ecuadorian researcher, founder of the Ecuador National Museum of Medicine and the great discoverer and editor of the long-lost work Flora Huayaquilensis by Juan Tafalla, a botanical masterpiece and the first flora of present Ecuador from the colonial period, in which the most common species of Capparaceae from coastal Ecuador were documented with splendid handmade, natural-sized illustrations. 

Habitat and distribution: known from the type in the vicinity of San Miguel de los Bancos toward Saloya, a lower montane secondary wet forest, in which individuals of Capparidastrum estrellae are scattered forest elements at 1230 m and may persist as solitary individuals in open areas. On the basis of field photographs sent by Jaime West to the first author, it is most likely that a second population of this taxonomic novelty occurs at 500 m on the same western side of Pichincha Province.
