Stenocereus zopilotensis Arreola-Nava and Terrazas, a new species from the Zopilote Canyon, municipality of Zumpango del Rio in the center of the state of Guerrero (Mexico), is described and illustrated. This new species is compared toStenocereus quevedonis J. G. Ortega,S. fricii Sánchez-Mej., andS. pruinosus (Otto) Buxb. based on morphological similarity. Moreover, the new species grows sympatrically...
Passiflora contracta, a new species from coastal forests of Brazil, is described and illustrated. Based on recent collections,Passiflora hypoglauca andP. luetzelburgii, two rare and overlooked species last collected in the 19th century, have had their descriptions emended, are illustrated here for the first time, and have had their distributions expanded.
A list is provided of all 358 taxa ofErythroxylum described from the Neotropics through the year 2000, including type specimen citations, probable synonymy, geographic distribution, and designation of 41 new lectotypes and one new neotype. The list includes 187 accepted species, eight accepted varieties, 27 infraspecific names of uncertain status, and 136 synonyms. A searchable specimen database and...
A new species,Ficus salicaria, is described from material cultivated as ornamental. The material is of uncertain provenance but was probably collected originally in Guyana.
A new species ofMonstera (Araceae),M. praetermissa, is described, illustrated, and compared to its most similar relatives,M. xanthospatha andM. obliqua. The new species is so far only known from Brazil, but has a broad distribution there, ranging from the south to the northeast of the country.
Two new narrow endemic species ofBegonia from the Atlantic coastal forests of Brazil,B. espiritosantensis andB. ibitiocensis, are described and illustrated.Begonia schenkii var.calvescens, an endemic taxon from the states of Santa Catarina and Rio Grande do Sul, is transferred to species rank, and described and illustrated. A distribution map is provided for all three taxa.
Dalea rupertii is proposed as new. It differs from previously known species in having calyx teeth with both spurred (1–2) and blister glands (4–6), and leaves 7–17 mm long, bearing 4–5 pairs of leaflets. It is known only from the southern portion of the state of Durango, Mexico. A description, a comparative table, and an illustration are provided.
We describe, discuss, and illustrate four new species, one inAdiantum (A. capillatum A. R. Sm. & Prado, from Ecuador) and three species inPteris (P. lellingeri A. R. Sm. & Prado, from Bolivia;P. venezuelensis A. R. Sm. & Prado, from Venezuela; andP. websteri A. R. Sm. & Prado, from Ecuador, Colombia, and Bolivia).
Sequences of the nuclear ribosomal internal transcribed spacer regions 1 & 2 (nrDNA ITS) including the intervening 5.8S region were analyzed cladistically for 43 individuals of 35 species ofScaphyglottis s.l. plus two outgroup taxa. Low levels of sequence divergence do not allow estimation of relationships among most clades, but the analyses indicate that four segregate genera (Hexisea Lindl.,...
Ossaea alloeotricha, described by Urban on the basis of material with very immature flowers, has been re-collected (in flower and fruit) in the cloud forests and moist forests dominated byPinus occidentalis in the vicinity of Pic le Ciel, 2150 m, on Morne Formon of the Massif de la Hotte (western group), Haiti. The mature flowers of this species have broadly elliptic to suborbicular petals with rounded,...
Lectotypes are selected for two taxa inCleomella, and a new combination is made inCleomella (Cleomaceae). Also presented is a key to the Intermountain West species and varieties ofCleomella, a description forCleomella hillmanii and a discussion of its varieties, and a brief discussion on the distribution of the taxa ofCleomella.
Tovomita calophyllophylla, from white sand forests of the Amazonian lowlands of Colombia and Peru, is described. The species is unique by its leaves and petioles which somewhat resemble those of two other genera of Clusiaceae,Calophyllum andGarcinia.
Tigridia amatlanensis is described and illustrated as a new species from Mexico. It is recognized by its nodding flowers and its inner and outer tepals cirrhous and markedly dimorphic in length. It is most closely related toT. hallbergii subsp.hallbergii andT. meleagris. Other morphologically similar species areT. catarinensis andT. molseediana.
A closely related group of Great Basin endemic dradas,Draba cusickii O. E. Schulz,D. sphaeroides Payson, andD. pedicellata (Rollins & R. A. Price) Windham, are described, keyed, and discussed in order to putD. pedicellata var.wheelerensis N. H. Holmgren, var. nov. in perspective.Draba cusickii is endemic to Steens Mountain of southeastern Oregon, andD. sphaeroides is known only from three mountain...
