“…Among other taxa of Araceae, the genus Anthurium is the largest of the family and one of the most important taxa, with approximately 900 species (JUDD et al, 2009), of which several new species were registered in Brazil (COELHO; MAYO, 2000;COELHO, 2006;CATHARINO, 2008;COELHO, 2010;COELHO, 2011;GONÇALVES, 2012). The species of this genus are distributed in the American tropics, from northern Argentina to Mexico, and it consists of terrestrial or epiphytic rain forest plants (DAHLGREN et al, 1985).…”

Among other taxa of Araceae, the genus Anthurium is the largest of the family and one of the most important taxa. Some species of this genus have been used as a condiment, and its plants as ornaments and medicines for over a century. Anthurium maricense is an endemic species from "restingas" of Rio de Janeiro, Brazil, and it is used as ornamental and medicinal plant. This paper aimed an anatomical and toxicological study of its vegetative organs. A. maricense has subterraneous rhizome, adventitious roots and complete leaves. The anatomical features of vegetative organs are similar to other species of Araceae and genus Anthurium, especially the velamen in roots and calcium oxalate crystals in all organs. Under scanning electron microscopy (SEM), longitudinal grooves were observed in the raphides. For toxicological analyses, whole (with crystals) and centrifuged (free from crystals) fractions of the juices of each organ were administered via mouthwash and plantar inoculation to groups of five mice. The formation of edema was observed at 1, 3, 6, 24 and 96 hours and 7, 14, 21 and 28 days. The oral inoculations presented negative results for all groups, without edema. The plantar inoculations showed differing results: with centrifuged juices, mild edema formed but regressed; with whole juices, some animals presented severe edema. Our results indicated distribution and morphology of raphides and diverse chemical substances were related to the edematogenic process. A. maricense may potentially induce more chronic edema if compared to other species of Araceae.

“…En Colombia hay muchas zonas que no han sido estudiadas y no hay un número exacto de especies de anthurios descritas. En Brasil los estudios arrojan, alrededor de 130 especies de Anthurium, es un país con gran diversidad de este género (Temponi & Coelho 2011) y es de anotar que hay anthurios que su distribución geográfica puede alcanzar dos países, como ocurre con muchos anthurios que han sido ubicados en Panamá, pero también son encontrados en las selvas del Choco, un ejemplo de ello es el caso de Anthurium obtusum y A. crystallinum Linden & André que por muchos años se creyó que era originario de Panamá pero se ha concluido que es originario de Colombia.…”

ResumenTres nuevas especies son descritas para Colombia, Anthurium combeimense, A. oyuelae y A. sanjorgense, plantas endémicas de la región del cañón del río Combeima en el municipio de Ibagué del departamento del Tolima. Una especies es un miembro de la sección Pachyneurium, series Pachyneurium caracterizado por sus hojas en forma de roseta, internados cortos y raíces compacto. Dos especies son miembros de sect. Calomystrium caracterizado por sus catafilos intactos y hojas ovato-sagitata. Palabras-claves: Araceae, Colombia, nueva species, departamento de Tolima. AbstractThree new species are described for Colombia, Anthurium combeimense, A. oyuelae and A. sanjorgense. The species are endemic to the valley of the Río Combeima in the municipality of Ibagué in Tolima Department. One species is a member of section Pachyneurium, series Pachyneurium, characterized by rosulate leaves, short internodes and dense roots. Two species are members of sect. Calomystrium characterized by their long-petiolate leaves, persistent intact cataphylls and ovate-sagittate leaf blades.

“…Levantamentos florísticos de Araceae para o estado de Minas Gerais têm revelado um grande número de novas espécies (Sakuragui & Mayo 1999;Gonçalves & Temponi 2004;Temponi & Coelho 2011), bem como novos registros para o estado (Almeida et al 2005;Temponi et al 2006). Estes resultados reforçam a necessidade de estudos e o incremento de coletas em outros remanescentes florestais e ambientes preservados do estado.…”

O Parque Estadual de Ibitipoca está situado no sudeste do estado de Minas Gerais, entre os paralelos 21°40'15"‒21°43'30"S e os meridianos 43°52'35"‒43°54'15"W, totalizando 1.488 hectares. Apresenta diversas formações vegetacionais como a Floresta Atlântica e os campos rupestres. O presente trabalho teve como objetivo realizar o levantamento das espécies de Araceae do Parque Estadual de Ibitipoca, com uma chave de identificação, descrições, ilustrações, informações sobre habitats de ocorrência. Amostras férteis foram coletadas em 2004 e 2005 e incorporadas nos herbários RB e SPF. Foram reconhecidas 10 espécies pertencentes a três gêneros, sendo Anthurium Schott o mais representativo com cinco espécies, seguido por Philodendron Schott com quatro. Asterostigma Fisch. & C.A.Mey. foi representado por apenas uma espécie.
