A new species of Glossoloma is described from the western Andean slopes of the Pichincha Province in northern Ecuador. Glossoloma wiehleri J.L.Clark & Tobar is differentiated from all other congeners by an epiphytic habit, elongate scandent shoots that exceed four meters in length, and coriaceous leaves with a velutinous indument on the lower leaf surface. The new species is illustrated, featured with field images from recent expeditions, and assigned the category of Endangered (EN) according to IUCN Criteria.

A New Species

We describe and illustrate a new species of Beilschmiedia, from the Osa Peninsula of Costa Rica. It is distinguished by its small flowers, which are turbinate to campanulate, with six fertile stamens and pubescent ovary, in addition it has alternate leaves along the twigs, with the lower leaf surface glabrous and not glaucous. In the field, it can be recognized by its stature, a very large tree, with the bark reddish, and peeling in large plates. Among described congeners it is superficially similar to B. hexanthera, from French Guiana, which also has six fertile stamens, and staminodes of whorl III columnar, but differs in having a pubescent ovary and larger, more branched inflorescences.

The new species Dorstenia marijanmatokii from Rwanda is described. It differs from Dorstenia nyungwensis in the discoid and entirely purple receptacle with shorter primary appendages and more numerous and irregular secondary appendages, and the densely tomentose lower leaf surface with purple venation. First records of Dorstenia brownii and D. psilurus from Rwanda and a key to the species of Dorstenia for Rwanda are provided.

A new vagrant species of Diptilomiopidae mite, in the Diptacus Keifer, 1951 genus, namely Diptacus rubuscolum sp. nov., living on the lower leaf surface of blackberry-Rubus sp. (Rosaceae) in South Brazil, is described and illustrated. In addition, Acalitus orthomerus Keifer, 1951, for the first time reported in Brazil and even in South America; a supplementary description of this species is presented based on females, males and immature specimens associated to the drupelets. Main morphological differences distinguishing the new Diptacus species and A. orthomerus species from those belonging to the same genera or morphologically similar also associated with Rubus are presented.

Surface Comparison

Study of selected specimens of Gymnomitrion collected by D. G. Long in Yunnan, China, revealed a new species, G. fissum Mamontov et Potemkin, sp. nov., with a fissured leaf surface. Comparison of SEM images of the leaf surface and leaf cross sections shows that the leaf surface of G. fissum is different from that of other known species with a superficially similar leaf surface, i. e. Mylia taylorii, M. verrucosa s. l. and Trabacellula tumidula. It has fissures around the cell lumen rather than grids and perforations. Outer cell walls of Gymnomitrion fissum are much thicker than in Mylia taylorii, M. verrucosa s. l. and Trabacellula tumidula, and their outer layers tend to be partly or completely caducous. G. fissum is related to the group of species assigned to the former genus Apomarsupella.

High-throughput sequencing, when combined with taxonomic expertise, is a powerful tool to refine and advance taxonomic classification, including at the species level. In the present work, a new species, Plantago campestris, is described out of the P. commersoniana species complex, based on phylogenomic and morphological evidence. The main morphological characters that distinguish the new species from P. commersoniana are the glabrous posterior sepals and the slightly broader leaves. The new species is known from only three localities, all in natural high-elevation grasslands in Paraná and Santa Catarina states, southern Brazil. According to the IUCN criteria new species should be assessed as Endangered (EN). We present field photographs of P. campestris and related species, and we provide an identification key to the species previously included within the circumscription of P. commersoniana.

Behuria mestrealvarensis (Melastomataceae) from the state of Espírito Santo, Brazil, is described, illustrated and compared with B. capixaba, the species most similar to it. Behuria mestrealvarensis differs from B. capixaba by the glabrous petioles and hypanthia, by the solitary flowers or these in simple or compound triads up to 7 flowers, elliptic bracteoles almost the same size of the pedicel and hypanthium, sepals with eciliate margins and ovary apex with trichomes up to 0.5 mm. It occurs in a single locality, on an isolated, ca. 800m elev. inselberg. Due to its restricted occupancy area, fragmented landscape and poor habitat quality, this species must be considered as Critically Endangered according to IUCN criteria.

Magnolia napoensis, a new species from the Amazonian lowlands of Ecuador and Peru is described and illustrated. This species belongs to subsection Talauma; it is similar to M. rimachii in leaf shape but differs from the latter in being taller with a larger diameter and having fewer lateral leaf veins, more numerous hypsophylls, larger flowers, longer outer petals, more numerous stamens and fruits ovoid and ribbed vs. subglobose and smooth. The new species differs from M. neillii by its leaves with fewer lateral veins, glabrous petioles and terminal internodes, more numerous hypsophylls, fewer stamens and ovoid fruits of smaller size, with fewer carpels. Magnolia napoensis is assessed as endangered (EN B2ab(iii)) in accordance with the IUCN criteria.

Priogymnanthus colombianus, a new species and the first record of the South American genus of Oleaceae for Colombia is described and illustrated also we present a dichotomic key for the known species of genus. The new species differs from the three knowns for Priogymnanthus by: leaves oblong or oblong-elliptic, completely glabrous, petioles 10–17 (19) mm; inflorescences 15–20 (25) mm in length, with glabrous rachis, anthers about 3 mm length; fruits (10) 12–15 mm in diameter. P. colombianus occurs on premontane and dry forest in Colombia between 719 and 1213 m of elevation. Based on general threats to its ecosystems and few records found, we categorize the species as EN (endangered) following IUCN criteria.

A new species of Spigelia subg. Spigelia sect. Graciles, S. alborubra, is described and illustrated. It is known from Campos Rupestres and Caatinga s.s. in the states of Bahia and Pernambuco, Brazil. It is similar to S. pulchella, based on its exserted stigma and red corolla tube, but S. alborubra differs by its shorter corolla, with a constriction at the apex of the tube, whitish corolla lobes which open only at the apex, and by its inserted stamens. Based on the habit and on the shape of the corolla, it is superficially similar to other species of Spigelia subg. Spigelia sect. Graciles, such as S. gracilis, S. linarioides, S. schlechtendaliana and S. spartioides. However, the new species is easily distinguished from them by its salverform corolla and exserted stigma. According to the IUCN criteria, it is classified as Endangered (EN) due to its narrow distribution.
