Two new forest species, Eugenia sapoensis sp. nov. and Eugenia breteleri sp. nov., from Liberia and Gabon respectively, are described and illustrated here. Both are shrubs with comparatively large red fruits. They resemble each other, but E. breteleri differs from E. sapoensis in having twigs with conspicuously peeling bark, 6-8 pairs of main later...

... large pinkish red fruits was collected in the forest near the Sapo National Park in Liberia. It is named here Eugenia sapoensis sp. nov. Most Eugenia species in this region have smaller fruits that are often very dark reddish or dark purplish at maturity European Journal of Taxonomy 113: 1-9 (2015) as in the case of Eugenia calophylloides DC. (Fig. 1). Most species are larger too, up to medium-sized understory trees, and are flowering and fruiting much more profusely. The new species could not be keyed out with the Flora of West tropical Africa (Heine 1963) or with the Flore du Gabon (Amshoff 1966). The closest other species from the Guinea-Congolian Region seems to be E. ...

RESUMO Este estudo objetivou caracterizar aspectos relacionados à dispersão de propágulos de Myrceugenia euosma (O. Berg) D. Legrand (Myrtaceae) em um fragmento de Floresta Ombrófila Mista em Urupema, SC. Para isso, foram avaliados 29 indivíduos reprodutivos quanto à frequência de visitantes, chuva de propágulos, remoção e caracterização de frutos....
In this research we present the anatomical study of Psidium widgrenianum O. Berg., Myrtaceae, known as "araçá", which presents anti-inflammatory and anti-neoplasic properties. The structural characteristics, the surface of leaf blade is shown in optical microscopy (OM) and in scanning electron microscopy (SEM), contributes to the knowledge of the m...
Myrtaceae é uma família pantropical com cerca de 5500 espécies e 132 gêneros e que se destacada pela taxonomia complexa (caracteres crípticos) e difícil. No Brasil, Myrtaceae está representada por 23 gêneros e 974 espécies e é uma das famílias mais representativas na Cadeia do Espinhaço. O objetivo deste trabalho foi realizar o levantamento floríst...

... The impressive Ecological Atlas of Woody Plant Species by Poorter et al. (2004), shows the profiles of the rare and endemic species of the Upper Guinean forests. The number of new endemic species discovered since the appearance of the second edition of the Flora of West Tropical Africa is considerable and the botanical exploration of the Upper Guinean forests, especially of Liberia, continues to yield new species (Lachenaud & Jongkind 2013;Jongkind 2012Jongkind , 2015Jongkind , 2016Jongkind , 2017Jongkind , 2019. A specimen of an undescribed species of Antidesma L. (Phyllanthaceae) was recently collected in Liberia by C.C.H. Jongkind, who is still actively exploring the botanical diversity of this country. ...
Background and aims – The botanical exploration of Liberia, notably by C.C.H. Jongkind, has yielded several new species. One of his recent collections proved to contain a new species of Antidesma.Methods – Normal practices of herbarium taxonomy were applied to study the relevant herbarium material available at BR, K, and WAG. The relevant collecting data are stored at the Naturalis Biodiversity Center, Leiden, Section Botany. Map Maker was used to produce the distribution map.Key results – Antidesma jongkindii Breteler is described as a new species and illustrated. Its distinction from the other three species present in Liberia is presented in a key. The species is proposed to be listed as Critically Endangered [CR B2ab (ii)] following IUCN criteria.
... Its appearance and position looks very much like an inner, staminodial row of stamens and may better be conceived as such. From this point of view, and looking at Keay's key to the genera of Medusandraceae (Keay 1958), the two genera become morphologically more similar: Soyauxia has now staminodes and no disc just like in Medusandra. The fertile stamens of e.g. ...

Background – Botanical exploration of the Sapo National Park in Liberia resulted in the discovery of a new species, which, after DNA investigation, was identified as belonging to Soyauxia of the small family Peridiscaceae.
Methods – Normal practices of herbarium taxonomy and DNA sequence analysis have been applied. All the relevant herbarium material has been studied, mainly at BR, K, P, and WAG. The presented phylogenetic relationships of the new Soyauxia species is based on rbcL gene sequence comparison, inferred by a RAxML analysis including 100 replicates fast bootstrapping. The distribution maps have been produced using Map Maker Pro. Relevant collection data are stored in the NHN (Nationaal Herbarium Nederland) database.
Key results – The new species Soyauxia kwewonii and an imperfectly known species are treated in the framework of a synopsis with the six other species of the genus. rbcL sequence comparison followed by RAxML analyses yielded a well-supported match of S. kwewonii with the Soyauxia clade. Its conservation status according to the IUCN red list criteria is assessed as Endangered. Its distribution as well as the distribution areas of the genus and of the remaining species are mapped. Soyauxia ledermannii is neotypified and the most common species in Gabon, S. glabrescens, is also illustrated.
Jongkindia, a small tree species endemic to a local area in southeast Liberia, is described as a new monotypic genus of Passifloraceae sens. lat. Its only species Jong-kindia mulbahii combines floral characteristics of the Turneraceae and fruit characteristics of the Passifloraceae s.s. (or subfamily Passifloroideae in APG) and can therefore be regarded to occupy an isolated morphological position. This is confirmed here by DNA sequence-based phylogenetic analyses including most Passifloracean genera, which places it as sister to Passifloroideae. We delineate 16 morphological characters and their states and optimise them on our reconstructed phylogenetic tree. Based on these results we consider the Passifloraceae fruit characteristics (berries with arilled seeds) as synapomorphic for Passifloroideae. The monotypic Pibiria and Jongkindia are predominantly characterised by autapomorphies. On the other hand, the Adenia/ Passiflora clade is characterised by polymorphisms. We place Jongkindia in a new tribe Jongkindieae Breteler & F.T.Bakker. A draft plastome sequence for Jongkindia mulbahii is presented and evidence for two mitome to plastome (mtpt) fragment transfers is discussed. Structurally the Jongkindia plastome appears similar to that of Populus, Adenia, Mitostemma, Dilkea, and Passiflora pittieri, but not to contain the previously-described major inversions within other, more derived, Passiflora plastomes.
