Plants of Brazil

The immense diversity of algae, fungi and plants in Brazil is represented in the country's herbaria and in several foreign ones. The "National Institute of Science and Technology (INCT) Virtual Herbarium of Flora and Fungi in Brazil" is an initiative that proposes to integrate online, in a free and open way, information from herbarium collections in Brazil and abroad that have collections made in Brazilian soil.

Family of major economic importance not only for its fruits but also for its ornamentals. Well-known edible fruits are very variable being drups (fleshy with a stone) as in apricot, cherry, nectarine, peach, plums, prune, almond; pomes as in apple, quince, pear, loquat; aggregates (with free carpels) as in blackberry, raspberry, strawberry. The beautiful tree Prunus lusitanica is widely planted as a hedge as are Spiraea, Cotoneaster, Pyracantha, Crataegus and some others. Rosa is the best-known ornamental species and there are many thousand hybrids and cultivars. Rose perfumes are made from rose oil, a mixture of essential oils obtained by steam distilling the crushed petals.

Plants of São Tomé and Príncipe

São Tomé and Príncipe (STP) is one of the most interesting biodiversity hotspots in the Gulf of Guinea, with a large percentage of endemisms.
The Herbarium of the University of Coimbra has one of the main flora collections from the archipelago since the 19th century, many of which were the very first specimens collected of their species. This important collection contains precious information on the rich plant diversity of São Tomé and Príncipe, that will be made public for the first time with this transcription project.

Saxifragaceae are plants primarily in the northern hemisphere, from the Arctic to temperate zones. Interestingly, they are also found in the tropical mountains. The family's center of diversity is in eastern North America, east Asia and the Himalayas. They are generally perennial herbaceous with mostly basal and often succulent leaves. The flowers, although small, are numerous, and several species are cultivated as ornamental.

Grasses of Guinea-Bissau

Guinea-Bissau is a small tropical country (2.5 times smaller than Portugal) more than 20% of its territory being occupied by water. Mangroves thrive along the coast and river banks. There are also areas of rice paddies, sub-humid and dry forests, and inland savannas. Here, grasses play an important role. Those grasses that develop in the salty areas, with soil saturated with salt, where few species can survive, are also of major ecological importance.
