Background and aims: The bryophyte ﬂora of Argentina is currently under study,

nevertheless, there are still extensive areas unexplored, such as Santiago del Estero

with only three records of bryophytes to the entire region. The aim of this work was to

contribute to the knowledge of the moss ﬂora of Santiago del Estero province, through

the collection of samples in Copo National Park and surroundings.

M&M: The specimens were collected in the Copo National Park and surroundings,

processed and studied according to traditional techniques for bryophytes. Microscopic

characters were observed with stereoscopic and light microscopy. A list of the species

found is presented, with comments on the differentiating characters, habitat and

distribution.

Results: The following moss taxa were found to be new records for the province: Aloina

radiculosum; Syntrichia chisosa, Trichostomum brachydontium and Venturiella glaziovii.

The range of distribution of Tricherpodium beccarii is extended to the northeast of the

province.

Conclusions: Eleven species and one subspecies, distributed in ten genera and ﬁve

families, are newly reported for the province of Santiago del Estero. The range of

distribution of one species is extended to the northeast of the province. These ﬁrst

studies highlight the unexplored ﬂoristic richness of the region and its vulnerability due

to the accelerated advance of the agricultural-livestock border.

reSumen

Introducción y objetivos: La ﬂora briofítica en Argentina se encuentra actualmente

en estudio, sin embargo, todavía quedan extensas áreas sin explorar, como lo es la

provincia de Santiago del Estero, con solo tres registros de brióﬁtos en toda la región.

El objetivo de este trabajo es contribuir al conocimiento de la ﬂora de musgos de la

provincia de Santiago del Estero a través de colecciones en el Parque Nacional Copo

y sus alrededores.

M&M: Las muestras fueron coleccionadas, procesadas y examinadas de acuerdo a las

técnicas clásicas para brióﬁtos. Los caracteres microscópicos fueron observados con

microscopio óptico y estereoscópico. Se presenta un listado de las especies hasta el

momento encontradas en la provincia, con comentarios sobre el hábitat y la distribución.

Conclusiones: Once especies y una subespecie, distribuidas en diez géneros y cinco

familias se registran por primera vez para Santiago del Estero. El rango de distribución

de una especie se extiende al noreste de la provincia. Estos primeros estudios ponen

de maniﬁesto la riqueza ﬂorística inexplorada de la región, y la vulnerabilidad de la

misma debido al acelerado avance de la frontera agrícola ganadera.
