Manipulus Rubiacearum - V. A revision of the genus Capirona.

The taxonomic histort of the genus Capirona is presented. Complete synonymies, descriptions, common names, distributions and discussions are given for Capirona and its two species C. descorticans and C. leiophloea. The generic distribution is the Amazon valley and eastern Guianas and coincides with that of the genus Hevea. C. descorticans is know from the western and southeastern Amazon valley; C. leiophloea is reported from the eastern Guianas and the northeastern Amazon valley. The zone of contact between the two species is along the southern edge oh the Amazon River and the lower drainage of the Rio Tapajoz in Pará, Brazil.

A review of Taxithelium (Sematophyllaceae) in Brazil

Taxithelium is represented in Brazil by three species. Each species is described and illustrated and its distribution in Brazil is mapped. Taxithelium planum (Brid. ) mitt. is weedy but mainly confined to the low elevations of Amazonia; T. pluripunctatum(Ren. & Card.) Buck is reported for the first time for Brazil from three localities; T. juruense (Broth.) Broth. is apparently endemic to Acre.

Tropical lowland mosses disjunct between Africa and the Americas, including Calyptothecium planifrons (Ren. & Par.) Argent, new to the Western Hemisphere

Calyptothecium planifrons (Ren. & Par.) Argent is reported new to the Western Hemisphere based on two recent collections from Brazilian Amazonia, in Pará and Rondônia; C. planifrons was originally described from Madagascar. Forteen Other species of mosses with apparently disjunct distributions between tropical Africa and tropical America are also discussed. It is likely that mos or all of this species discussed will prove to have wider distributions in the tropics when world-wide revisions are carried out.
