There are described and illustrated Eugenia andiraana, E. libens, Myrcia iranduba, M. javariana, M. piptocalyx and Plinia rufiflora, all from Amazonian Brazil; additionally, affinities and conservation issues are discussed for each species. Eugenia andiraana, from the state of Acre, is morphologically related to E. minuscula, differing by its pilose, longer blades; E. libens, from the state of Roraima, is related to E. callichroma, but has wider blades, persisting bracteoles and locules of the ovary with less ovules; M. iranduba is related, between others, to M. inaequiloba, but differs by its scarcely reticulated blades with acute or shortly acuminate apex and inflorescences with deciduous bracts; Myrcia javariana, from the state of Amazonas, is related to M. megapaniculata, but differs by its winged twigs, narrower blades and applanate inflorescences; M. piptocalyx, from Acre, is related to M. splendens but differs by its blades with larger glandular dots and deciduous calyx lobes, and Plinia rufiflora, from the state of Pará, is related to P. costata, but has blades with midvein and lateral veins raised on both sides and flowers with rufescent trichomes.

There are described and illustrated four species of Myrtaceae from Amazonian Brazil: Eugenia altoalegre, from the state of Roraima, and Eugenia fortuita, Myrcia amanana and Plinia tapuruquarana, these three from the state of Amazonas. Eugenia altoalegre is related to E. tachirensis, being distinguished by its larger, acuminate blades and inflorescences with two or more flowers; Eugenia fortuita is related to E. spruceana, but has larger inflorescences and densely pilose flowers; Myrcia amanana is related to M. splendens, but has a greyish floccose indumentum, and Plinia tapuruquarana is related to P. pinnata, but has wider blades, thicker petioles and larger flowers. Additionally, conservation issues are discussed for each species.

Amazonian Brazil

Bryophyte diversity in Amazonian Brazil is high, presently recorded at 514 species distributed among 36 families and 89 genera. Comparisions of species richness among the Amazonian states of Brazil suggests that the bryoflora of Acre is still underestimated, presently recorded at 106 species distributed among 33 families and 63 genera. After two field trips, the diversity increased 50% showing that the bryoflora is still poorly known. Collection data and comments on morphology, ecology and distribution are given for sixty-two species of bryophytes collected in the state of Acre, Brazil, which are new (fifty-two species) or interesting floristic records (ten species). Microlejeunea crenulifolia (Gottsche) Steph. and Stictolejeunea balfourdii Mitt. are new records for Brazil and fifty species are new records for Acre.

A New Species

A new species of Tragia from the state of Oaxaca, Mexico is described and illustrated; it is different from other known Mexican species, although somewhat similar in habit to T. nepetifolia. Tragia chiltepeca is an erect herb with deeply cordate leaves with an acuminate apex and a long petiole, a long pedunculate inflorescence, a single pistillate flower in the proximal node, several male flowers at the distal nodes, and pyriform buds. This species is endemic to the Tuxtepec district. A taxonomic key is provided to distinguish this from other Tragia species in Oaxaca.

There are described and illustrated Myrcia caloneura, M. oreophila, M. sticta and M. tarauacana. Myrcia caloneura, from the states of Amazonas and Pará, is related to M. rugosior, but differs by its adult glabrescent blades and tetramerous flowers; M. oreophila, from the state of Roraima,is related to M. aegiphiloides, but has pilose, loosely reticulate blades and pilose flowers; M. sticta, from the state of Amazonas, is close to M. splendens, but has blades with rounded to cordate base and larger and easily visible glandular dots, and M. tarauacana is related to M. aequatoriensis and M. crassimarginata but has shorter blades and longer inflorescences. Conservation status of each species is also suggested.

Various authors have emphasized the spatial information resident in an electron micrograph taken with adequately coherent radiation. In view of the completion of at least one such instrument, this opportunity is taken to summarize the state of the art of processing such micrographs. We use the usual symbols for the aberration coefficients, and supplement these with £ and 6 for the transverse coherence length and the fractional energy spread respectively. He also assume a weak, biologically interesting sample, with principal interest lying in the molecular skeleton remaining after obvious hydrogen loss and other radiation damage has occurred.
