A New Species

Bazzania amadoi is a new species described and illustrated here based on material collected during a study of the bryophyte flora in the Brazilian Amazon Mountains, Monte Roraima National Park, Roraima State, Brazil. Bazzania is the largest genus of Lepidoziaceae,with ca. 30 species recognized in South America. A combination of leaves slightly bifid and recurved to the ventral side, underleaves imbricate and connate with the leaves on only one side, and vittae absent with only a region of larger leaf cells in the mid-lower portion of the leaves (vitta-like), distinguishes B. amadoi from the similar B. gracilis. The new taxon is placed within the key for the identification of species from the Brazilian Amazon domain, and represents an addition to the rich endemic flora of the Brazilian Amazon mountains of the Guiana Highlands. A detailed illustration of the new species is included, and also its informal conservation assessment.

A new species of Genlisea section Genlisea from the white-sand savannas (“campinaranas”) of Brazilian Amazon is described and illustrated, providing remarks on habitat and ecology as well as SEM seed images. Genlisea multiflora has been recorded from Viruá National Park, and is of affinity to the large, purple-flowered species G. sanariapoana and G. guianensis. An identification key to all Genlisea species north of the Amazon is presented.

A New Species

ABSTRACT We describe and illustrate a new species of Coccoloba (Polygonaceae), named Coccoloba gigantifolia, from the Brazilian Amazon. It resembles Coccoloba mollis Casar, but differs from the latter species by its much larger leaves in the fertile branches. The species has only been recorded in the Madeira River basin, in the states of Amazonas and Rondônia, in the central and southwestern Brazilian Amazon. The description was based on herbarium material, cultivated plants, and individual trees in their natural habitat. We provide illustrations, photographs, and an identification key with morphological characteristics that distinguish the new taxon from the other two related taxa of the Coccoloba sect. Paniculatae, as well as comments on the geographic distribution and conservation status of the species.

Liparis popaensis, a new species of Orchidaceae, is described from Popa Mountain National Park, central Myanmar. Liparis popaensis is morphologically similar to L. odorata but it differs from the latter by having oblong-lanceolate dorsal sepal, column with two triangular wings and lip with a pair of subconical and basally adjoining calli at its base. Identification key and colour photographs are provided. A preliminary conservation assessment according to the IUCN Red List Categories and Criteria is given for the new species.

A New Species

Gravesia serratifolia, a new species from upper elevations of Marojejy National Park in northeastern Madagascar, is herein described, illustrated, mapped, and compared with similar species. It is readily characterized by its sparingly branched habit, leaf blades coarsely serrate with a moderate to sparse lepidote indumentum on both surfaces, inflorescence of few-flowered dichasia, calyx obsolete or evident as depressed truncate undulations with prominent calyx teeth that are laterally compressed when fresh, filaments with rusty-brown glandlike indumentum, and dorso-basal staminal appendages linear-oblong and widely spreading to coiled. A conservation assessment of Vulnerable is recommended for this species based on IUCN Red List Categories and Criteria.

A New Species

Pseudochirita trifoliata, a new Gesneriaceae species from Pu Luong-Cuc Phuong limestone mountain range in northern Vietnam is described and illustrated here. This new taxon is the second species of the narrowly endemic genus Pseudochirita which is known from limestone areas in southern China and northern Vietnam. It is easily distinguished from P. guangxiensis by a set of differences on the leaves, bracts, calyx, external corolla indumentum, staminode number, pistil length, ovary indumentum, style indumentum, and capsule length. A detailed description, illustration, information on distribution, ecology, phenology, provisional conservation assessment using IUCN categories and criteria of the proposed new species, and comparison with its similar species, are also provided.

Isertia psammophila, a new species from the white-sand campinarana forests in Northern Brazilian Amazonia is here described and illustrated. While molecular evidence indicates that it is closely related to I. rosea, I. parviflora and I. spiciformis, morphologically it is most similar to I. rosea by its short stipules and glabrescent leaves. Isertia psammophila occurs in sympatry with I. rosea and I. parviflora in the Viruá National Park, Roraima, Brazil, and these three species can be easily differentiated by morphological characters, which are here discussed.

Apical Axis

Backgrounds and aims: Hantzschia Grunow is a genus characterized by having valves asymmetric to the apical axis, markedly dorsiventral, with an eccentric raphe on the ventral side supported by fibulae and ‘hantzschioid’ symmetry of the frustules. In 1942 J. Frenguelli published the flora of diatoms of Neuquén province (Argentina), work in which he erected Hantzschia subandina as a new species for science. This work investigates the identity and taxonomic status of this taxon.  M&M: Original material of Hantzschia subandina of the Frenguelli Collection was analysed with light and scanning electron microscopy. Results: Observations on the material suggested two different species were included in the concept of this species assigned originally to the genus Hantzschia. Furthermore, neither of the two species present are assignable to the genus Hantzschia. Nitzschia subandina (Frenguelli) comb. nov. has a large central nodule and a slight asymmetry about the apical axis; it also produces frustules with nitzschioid and hantzschioid symmetry. We designate a lectotype for this taxon. In addition, another diatom in the same material with slight asymmetry about the apical axis has distinctive ornamentation on the mantle of the valve and produces nitzschioid and hantzschioid frustules. For this taxon we tentatively assign it to the non-monophyletic genus Nitzschia, describing it as N. araucana sp. nov. We discuss the possible phylogenetic position of this new taxon, and suggest that the genus Nitzschia is “the next Navicula” ready to be further subdivided into distinct genera.

Abstract—A new species of Acianthera, A. lueri, is described and illustrated based on material collected in the Amazon region of Peru. The combination of the glabrous ovary, 3-lobed lip, and long-tailed petals distinguish A. lueri from similar A. lanceana. The new taxon is placed within the key to identification of species reported from the Peruvian Amazon region.

A New Species

Myrcia lucasae (Myrcia sect. Gomidesia, Myrtaceae), a new species from the Bahia state, Brazil, is here described and illustrated. It differs from M. lughadhae, a closely related and sympatric species, by the strigose indumentum with ferruginous trichomes and the absence of ribs on fruits. It is also different and from M. virgata (Myrcia sect. Myrcia), by presenting thecae with irregular dorsal openings (characteristics of Myrcia sect. Gomidesia). Collections of M. lucasae have been constantly misidentified as the morphologically similar M. virgata, a species from a different section, which does not occur in the state of Bahia. Myrcia lucasae is endemic to the highly diverse campo rupestre vegetation of the Chapada Diamantina biogeographic province. We also provide preliminary conservation assessment, comments on distribution and ecological aspects of this new taxon.

Freshwater Diatom

Here we describe a new freshwater diatom species from the Cascade Mountain Range in Washington State, including observations of living cells and chloroplast structure. The species represents the fourth known extant species within the genus, as most species of Tetracyclus Ralfs are extinct. The new species can be distinguished from other Tetracyclus species and Diatoma mesodon Kützing by its lanceolate-elliptical shape, apiculate ends, small size, rimoportula placement, and distinct septa pattern. The distribution of the new taxon is currently catchments within the Mt. Baker-Snoqualmie National Forest and Mount Rainier National Park, and is found in greatest abundance in aerophilous, moss and liverwort habitats in first- and second-order streams.
