A New Species

Aspidistra magnifica, a new species from Mount Cà Đam, Quảng Ngãi Province, Central Vietnam, is described and illustrated. It is similar to A. maguanensis in having purple-black flowers, twelve perigone lobes and stamens, and a table-shaped pistil, but differs by its somewhat elliptic leaf blades, short flowering peduncles, much large broadly campanulate to bowl shaped perigone tube, longer outcurved perigone lobes and larger rounded stigma. A morphological description, two colour plates, the distribution, ecological information, the conservation status, and a comparison table of similar species are given.

A New Species

Pariana caxiuanensis (Poaceae) is described and illustrated as a new species from the Brazilian Amazon. The new species is characterized by having the leaves clustered at the apex of the leafy culm, fimbriae few to absent, dimorphic flowering culms, large ligules (2.5–4 mm long), and pubescent to hirsute synflorescences. We present a morphological description, illustrations of the new species, the conservation status assessment, and a key to differentiate P. caxiuanensis from its morphologically related congeners.

Hysterionica s.l. (including Neja) comprises ca. 15 species distributed mainly in the grasslands of southern Brazil, Uruguay, central and northern Argentina and Southern Paraguay. Based on field surveys, study of nomenclatural types and other specimens, and review of literature, a new species is proposed here, Hysterionica chamomilloides, endemic of mountainous regions of northern Uruguay, and southwestern Rio Grande do Sul state, Brazil. This work provides a detailed morphological description of the new species, information on its geographic distribution, habitat, phenology, conservation status, and discusses the main differences between H. chamomilloides and the morphologically most similar species. Illustrations, images and a key to the South American species of Hysterionica are also supplied.

Iucn Criteria

A new species of Pleroma from Serra dos Carajás, Pará state, Brazil, is described. Pleroma carajasense occurs in southeastern Amazonia, northern Brazil, in canga vegetation, on ironstone outcrops. It is morphologically related to Tibouchina caatingae, because both are shrubs with elliptic to oval leaves, conspicuous petioles (3–17 mm and 10–15 mm, respectively), a pair of elliptic bracteoles, and purple petals, anthers (both cycles) and style. Pleroma carajasense differs from T. caatingae by its chartaceous leaves (versus coriaceous in T. caatingae), with an obtuse to cuneate base (vs. obtuse to subcordate), hypanthium 4–7 × 1.2–4 mm (vs. 10–15 × 3–5 mm). According to IUCN criteria, this species should be considered endangered (EN). A morphological description, illustrations, photos in the field, scanning electronic micrographs of the leaf indumentum and seeds, information on conservation status and distribution are presented.

A New Species

A new species, Myrcia suberosa, is here proposed based in an ongoing taxonomic revision of Myrcia sect. Eugeniopsis, a group nearly endemic to the Atlantic Forest. Myrcia suberosa occurs in Brazil from Southern Bahia to Southern Rio de Janeiro states, but only three collections are known and the real distribution of the species is barely known. The new species is morphologically related to Myrcia pseudomarlierea and Myrcia teuscheriana, differing by sexual system, cork thickness, indument, and leaf and flower morphologies. Morphological description, images and conservation status are provided, as well as discussion about distribution, habitat, phenology and taxonomy.

Schinus pampeana is a new species from Brazilian Pampa. The new species was tentatively included in Schinus sect. Terebinthifolia, and is morphologically most similar to Schinus lentiscifolia and S. weinmanniifolia. We present here a detailed morphological description, a geographical distribution map, IUCN conservation status assessment, ecological data, photographs, and a table of diagnostic characters of S. pampeana and the most similar species. Schinus pampeana increases the total number of Schinus to about 49 species, of which eleven are recorded in Brazil.

Phyllagathis phamhoangii V.T.Pham, T.C.Vu & Ranil is described and illustrated from Quang Nam province, central Vietnam. Diagnostic features of the new species are the short acaulescent rhizomatous herbs with pink flowers. The described species is distinct from the closely allied P. nanakorniana in the sparse hairs on all its parts except petals and stamens, much longer petioles, dichasial inflorescences, longer hypanthia, stamens unequal in length, longer petals and ovary; and from P. subrotunda by the taller plants, smaller leaves with longer petioles, cordate to reniform blades with a shortly acuminate apex, dichasial inflorescences, longer and cylindrical peduncles, longer and narrower hypanthia. We suggest the IUCN conservation status for P. phamhoangii as Vulnerable.
