Huperzia reflexa and Lycopodiella cernua are recorded for the first time for the northwest of Argentina; along with the new records, the characters of the leaf morphology and spores are analyzed, and updated descriptions and geographical distribution of both taxa are also given. Three of the four genera of the Lycopodiaceae are present so far in the area: Huperzia, Lycopodium and Lycopodiella, and the number of species come to nine. To facilitate the recognition of all taxa, this paper also includes a key for their determination.

A total number of 36 epiphytic lichen species was identified growing on eleven phorophyte species in the coastal shrub-land of SE Cuba. Sixteen species are new records from Cuba. Pyrenula ochraceoflavens was the most frequent species and Plumeria stenophylla was the phorophyte containing the highest lichen richness (13 species). Mostly species are crustose, whereas nine are foliose but developed small thalli, and only one was fruticose (Ramalina complanata). Despite of the xeric climate, we found a high number of lichens with Trentepohlia as photobiont, a tropical alga common in absence of low temperatures and large thermal oscillations.

Thirty species of epiphytic lichens are reported being six new records for Cuba. Sixteen species only grow on the evergreen forest and ten species on the montane rainforest. Leptogium marginellum, Porina mastoidea and Parmotrema crinitum grow on both forests. The genus Coenogonium is more frequent on the evergreen forest.

New records for the bryological flora of the Iberian Peninsula are given. Pallavicinia lyelii and Plagiochasma rupestre are new records for the province of Cáceres. Drepanocladus aduncus is recorded for the first time in Soria and Lérida provinces, and D. polygamus in Lérida. Rhizomnium magnifolium is a new record for Ávila and León provinces. The presence of Triquetrella arapilensis in Madrid province has been confirmed. Furthermore, a list with the inedited places where Hygrohypnum, Rhizomnium, Sarmentypnum and Warnstorfia can be found in Andorra, Spain and Portugal is given, which is based on herbarium specimens and on specimens collected during several expeditions. Distribution maps of some species are provided.

The morphology and the distribution maps of ten taxa of the genus Placynthium is reported from the Iberian Peninsula. Placynthium lismorense is reported for second time in the Iberian Peninsula. The distribution areas of the taxa are enlarged. P. nigrum and P. subradiatum are the most frequent species, while P. dolichoterum is very rare.

Canna fuchsina is a name proposed to designate a new species of the genus Canna. The species grows in wild, dense colonies, which individuals bear large, intense fuchsia colored flowers, that reproduce sexually; plants thrive in humid, riverside coastal areas and small wetlands from Buenos Aires and Santa Fe Provinces, Argentina. After the study of their phenology and morphology, conclusions are that normal pollen grains and fruits are produced, and seed develops naturally in wild and in vitro conditions. The individuals of C. fuchsina resembles others belonging to the C. × generalis group, both in some vegetative and floral characters, such as the presence of wide staminodia. However, the name C. fuchsina must be applied only to the wild individuals that bear fuchsia colored flowers, since C. × generalis refers to a wide, not well characterized variety of taxa, with flowers of different colors and sizes. The characters of C. fuchsina are consistent with those of similar individuals with fuchsia colored flowers from United States and Australia, also linked to the group C. × generalis. C. fuchsina is considered the result of naturalization, after the introduction and spread of the group said, as ornamentals, since establish independent breeding colonies. A detailed description of the species, its morphology and ecology are given; the affinities with other wild species of Canna, and the importance of new characters in the systematics of the genus are also discussed.

We publish here the distribution maps along the Iberian Peninsula and the Balearic Islands of the genera Catenella Greville, Caulacanthus Kützing and Feldmannophycus Augier & Boudouresque. Each one of these genera is represented in this geographical area only by one species: Catenella caespitosa, Caulacanthus ustulatus and Feldmannophycus rayssiae.

In this paper the collection named “Plantes D´Espagne, 1850”, one of the exsiccata distributed by Eugène Bourgeau, at present kept in the herbarium of the Real Colegio Alfonso XII of San Lorenzo de El Escorial, (Herbarium RCAXII), has been studied. The historical importance of these sheets is increased due to the fact that some of them were used by Willkomm and Lange as chorological data in their classic Prodromus florae hispanicae.
