Taxonomic delimitation of Ceiba chodatii and C. speciosa (Malvaceae, Bombacoideae) in different phenological stages. Three species of Ceiba (Malvaceae, Bombacoideae) are cited for Argentina: C. chodatii, C. speciosa and C. pubiflora, differentiated by a few characters. The first two species are clea...

Ceiba delimitación taxonomía estadios fenológicos Ceiba delimitation taxonomy phenological stages. Taxonomic delimitation of Ceiba chodatii and C. speciosa (Malvaceae, Bombacoideae) in different phenological stages. Three species of Ceiba (Malvaceae, Bombacoideae) are cited for Argentina: C. chodatii, C. speciosa and C. pubiflora, differentiated by a few characters. The first two species are clearly distinguished in flowering stage, being difficult to identify them in other stages. The objective of this investigation is to check comparatively C. chodatii and C. speciosa in the search of greater characters that contribute to its delimitation. Native specimens of C. chodatii were studied in the Selva pedemontana and in Chaco serrano, also of C. speciosa cultivated in Salta and from herbaria. The vegetative and reproductive characters were studied with binocular loupe and MEB. A germination and seedling development test was carried out. The results show that the leafs from seedling to adult are differentiated in nerves and serrated of the margin. The differential characters in flower are: the size of the lobes in the staminodium column and the pubescence, the size of the anthers and collar, the total or partial union of the filaments, the shape, size and pubescence of the stigma and the type of basal pubescence of style. The fruits are differentiated by the thickness of the valves and the seeds by pubescence. Para Argentina se citan tres especies de Ceiba (Malvaceae, Bombacoideae): C. chodatii, C. speciosa y C. pubiflora, diferenciadas por pocos caracteres. Las dos primeras especies se distinguen claramente en etapa de floración, siendo complicada su identificación en otros estadios. El objetivo de esta investigación es revisar comparativamente a C. chodatii y C. speciosa en la búsqueda de mayores caracteres que aporten a su delimitación. Se estudiaron ejemplares nativos de C. chodatii en la Selva pedemontana y en Chaco serrano, también de C. speciosa cultivados en Salta y provenientes de herbarios. Se estudiaron todos los caracteres vegetativos y reproductivos, con lupa binocular y MEB. Se realizó un ensayo de germinación y desarrollo de plántulas. Los resultados muestran que las hojas desde plántula hasta adulto se diferencian en nerviación y aserrado del margen. Los caracteres diferenciales en flor son: el tamaño de los lóbulos en la columna de estaminodios y la pubescencia, el tamaño de las anteras y collar, la concrescencia total o parcial de los filamentos estaminales, la forma, tamaño y pubescencia del estigma y el tipo de pubescencia basal del estilo. Los frutos se diferencian por el espesor de las valvas y las semillas por pubescencia.
