Dicranopteris spissa L. V. Lima & Salino, comb. nov.
No full textDicranopteris spissa (Fée) L.V. Lima & Salino, comb. nov. (Figure 1–2) Mertensia spissa Fée (1869: 200). Type:— BRAZIL. Rio de Janeiro. Nova Friburgo. Macaé de Cima. Glaziou 2468 (lectotype designated by Lima & Salino 2018, P [P00633241] photo!, isolectotypes P [P00633243], [P00623242] photos!). Plants terrestrial or epipetric. Rhizomes 1.5–5.20 mm thick, with reddish-brown rigid simple or branched hairs, glabrescent to tomentose. Fronds scrambling, 2–4–(6)-forked; ultimate branches 12.5–30.5 cm × 2.8–5.5 cm, lanceolate, apex pinnatifid, base asymmetric, inner side with reduced segments, external side with conform segments; ultimate segments linear 3–16 cm × 2–2.5 cm, margins revolute; abaxial surface green or pruinose; pubescent, rarely glabrescent, with reddish, rarely whitish, multicellular hairs, on the segments midrib, bacilliform glandular hairs on the midrib, secondary veins and laminar tissue. Buds covered by reddish multicellular hairs; pseudostipule present, accessory branches simple to pinnatisect. Veins 3–4-forked. Sori median, with paraphyses, spores tetrahedral. Distribution and habitat:— Dicranopteris spissa is endemic to southeastern Brazil, occurring usually on edges of high montane forests of the south part of the Espinhaço Range, and Serra de Ibitipoca in Minas Gerais state as well as in the Serra do Mar in the states of Rio de Janeiro and São Paulo, between 900 – 1800 m (Fig. 2). In contrast, D. rufinervis has a distribution restricted to the mountains of the Espinhaço range in the north of Minas Gerais and Bahia, between 600 – 1500 m. Notes:— Dicranopteris spissa is morphologically related to D. rufinervis and it is mainly differentiated from that species by the following characters. Accessions of D. spissa have sparse pale-yellow to reddish hairs occurring only at the base of the segment on midrib (Fig. 1 D-G) versus red hairs densely spread through the segment’s midrib in D. rufinervis (Fig. 3 C-E). Secondary veins usually are deeply immersed at the laminar tissue with bacilliform glandular hairs versus secondary veins usually not sunk in the laminar tissue, usually with sparse red hairs in D. rufinervis. Finally, the rachis is glabrescent in D. spissa but pubescent in D. rufinervis. Conservation status:— Dicranopteris spissa and D. rufinervis are endemic to Brazil. Both species were categorized as endangered species according to IUCN Red List criteria. However, the records of the two species may be subsampled due to their resemblance with D. flexuosa, the most widely distributed species of the genus in Brazil. In contrast to the later, these two species do not occur in anthropogenic habitats and thus they are more sensible to environmental change. They occur in highland formations, usually near rock outcrops or in forest edges. Specimens examined: — BRAZIL.

Antonio 3958 (MO); Coclé, 19 January 1978, T. B . Croat 44555 (MO, UC). Distribution and habitat:— Meniscium cocleanum is distributed from Nicaragua, Costa Rica, and Panama. It usually grows inside or along the edges of tropical evergreen forest formations, on hillsides, often along trails, at 350–1050 m. Notes:— Meniscium cocleanum was, until this study, the only species of the genus known to have buds in the distal pinnae. Smith & Lellinger (1985) stated that the affinities of this species are uncertain. The new species described in this paper (Meniscium triangularis) also has distal proliferous buds, however, M. cocleanum has completely glabrous laminae whereas M. triangularis has a dense indument of scales and trichomes abaxially. Other differences have been previously discussed above.Published as part of Fernandes, Rozijane Santos, Yesilyurt, Jovita Cislinski & Salino, Alexandre, 2014, New species and combinations in Meniscium (Thelypteridaceae), pp. 1-11 in Phytotaxa 184 (1) on pages 7-8, DOI: 10.11646/phytotaxa.184.1.1, http://zenodo.org/record/515317
