“…Although the leaf of C. gracilis is considered glabrous (Rossini 2010;Saylor 1978), it still presents trichomes (Affonso et al 2014). The trichomes are uniseriated, nonglandular, and noncapitated (Fig.…”

Rupicolous and epiphytic plants have evolved in search of environmental light conditions, throughout their evolution, the former thriving among rocks, and the latter growing non-parasitically on other plants (trees). However, while their habitats have provided sufficient light, they are also characterized by xeric conditions. This work compares leaf morphoanatomy between the rupicolous Sinningia bullata Chautems & M. Peixoto and the epiphytic Codonanthe gracilis (Mart.) Hanst in order to find insightful correlations in their adaptations to water stress. It also presents the first description of the anatomy of the leaf of S. bullata. In vivo leaf samples were cut and fixed for analysis under both optical and the scanning electronic microscopy. Both plants were observed to have dorsiventral and hypostomatic leaf. Anatomically, the plants share the same type of stomata complex, i.e., amphianisocytic, with collateral vascular bundles in between the spongy and palisade parenchymas. The presence of water storage tissue and conspicuous epicuticular wax and cuticle are evidence of some of the adaptations that these plants have made against water stress. Thus, while both plants show similarities of morphoanatomical adaptations that enhance their ability to thrive in spite of water stress, S. bullata has evolved additional adaptive strategies, such as convexities of the epidermis and the presence of long trichomes.

Modern pollen fall in the Itutinga-Pilões Unit (Parque Estadual Serra do Mar), SP, Brazil

The Itutinga-Pilões Unit of the Serra do Mar State Park in São Paulo state is located in the municipality of São Bernardo do Campo, at km 35 on the Anchieta Highway, southeast of São Paulo's Metropolitan Region, approximately between the 23°45 0 and 24°00 0 S latitude and between 46°15 0 and 46°35 0 W longitude west of Greenwich. Artificial pollen traps were installed inside the park among open areas and forests. Pollen rain analysis revealed that there were 31 families, represented by 45 different pollen and spores morphotypes (including non-local taxa); out of these, 57% were arboreal pollen grains, 15% non-arboreal pollen grains and 28% monilophyte spores. Whereas the arboreal pollen was predominant in forest areas, the nonarboreal pollen ones were predominant in open areas, corroborating, therefore, with the places where the traps were installed. Most of the families and genus of plants found in the pollen rain in the park agree with the botanical data reported in the literature, including exotic plant such as Pinus L. and Eucalyptus L'Hér genera, which are in reforestation areas in the region. Betulaceae also occurs in the modern pollen rain record and is a native plant from the Andean forest, which is very common in Quaternary sediments in the southern region of Brazil as a consequence of wind pollination dispersion over long distances.
