Two new species of Cinnamodendron (Canellaceae) from Brazil

Two new species of Canellaceae from Brazil, Cinnamodendron brasiliense and Cinnamodendron catarinense, are here described. These species are known from the Atlantic Forest in the States of Sao Paulo (southeastern Brazil) and Santa Catarina (southern Brazil), respectively. Cinnamodendron brasiliense shares morphological similarities with C. occhionianum, but it can be distinguished by being a shrub or treelet up to 6 m tall with one or two flowers per inflorescence and obovoid fruits up to 1.8 cm long; whereas C. occhionianum is a tree 8–20 m tall with four or five flowers per inflorescence and globose fruits up to 1.5 cm long. Cinnamodendron catarinense resembles C. sampaioanum, but it has more flowers per inflorescences (6–8), the staminal tube below the anthers is shorter (about 1 mm long), and the anthers are longer (2.2–2.5 mm) than those of C. sampaioanum, which has 1–3 flowers per inflorescence, a staminal tube below anthers of ca. 3.2 mm long, and anthers 1–1.2 mm long. With the addition of these two species, Brazil becomes the country with the highest number of species of Cinnamodendron, holding six of the eight known species for South America. In this work, a key to all the species of Cinnamodendron from South America is also provided, as well as illustrations in photographs and line drawings of the two new species.
