Thus, traditional medicine remains the first choice or sometimes still, the only opportunity for Medicinal plants treatment. The purpose of this work was to popularize the medicinal plants used by Gabonese herbal therapists Ethnopharmacological survey in the treatment of cancers by an ethnopharmacological survey. Traditional healers Methods: In four localities of the Woleu-Ntem province, traditional healers were interviewed using a semi- Anticancer potential structured questionnaire. Collected data were analyzed by descriptive statistical methods and various quanti- Toxicity tative indices. The anticancer potential and toxicity of medicinal plants were confirmed by the bibliographic review. Results: Traditional healers of Woleu-Ntem use 51 species of medicinal plants in cancers management and re- lated diseases. These species are grouped into 49 genera and 29 families, the best-represented being Euphorbiaceae, Annonaceae, Apocynaceae, Myristicaceae and Rubiaceae. Barks are mainly used, followed by leaves. -
335 Genus Neptis Fabricius
AFROTROPICAL BUTTERFLIES. MARK C. WILLIAMS. http://www.lepsocafrica.org/?p=publications&s=atb Updated 15 January 2021 Genus Neptis Fabricius, 1807 Sailers In: Illiger, K., Magazin für Insektenkunde 6: 282 (277-289). Type-species: Papilio aceris Esper, by subsequent designation (Crotch, 1872. Cistula Entomologica 1: 66 (59-71).) [extralimital]. = Neptidomima Holland, 1920. Bulletin of the American Museum of Natural History 43: 116, 164 (109-369). Type-species: Neptis exaleuca Karsch, by original designation. Synonyms based on extralimital type-species: Philonoma Billberg; Paraneptis Moore; Kalkasia Moore; Hamadryodes Moore; Bimbisara Moore; Strabrobates Moore; Rasalia Moore; Seokia Sibatani. The genus Neptis belongs to the Family Nymphalidae Rafinesque, 1815; Subfamily Limenitidinae Behr, 1864; Tribe Neptini Newman, 1870. The other genera in the Tribe Neptini in the Afrotropical Region are Cymothoe and Harma. Neptis (Sailers) is an Old World genus of more than 160 species, 82 of which are Afrotropical. One Afrotropical species extends extralimitally. Neptis livingstonei Suffert, 1904 is declared to be a nomen nudum by Richardson (2019: 103). [Neptis livingstonei Suffert, 1904.

Known only from the type specimen from the type locality.] Neptis sextilla Mabille, 1882 is declared to be a nomen nudum by Richardson (2019). [Neptis sextilla Mabille, 1882. Naturaliste 4: 99 (99-100). Type locality: [West Africa?]: “Madagascar”. [False locality?]. Type possibly lost (not found in the NHM, London or MNHN) (Lees et al., 2003). The description suggests that although it may well have been recorded from Madagascar, it is either an aberration or a hybrid between Neptis kikideli and Neptis saclava (Lees et al., 2003). -
Toward a Phylogenetic-Based Generic Classification of Neotropical Lecythidaceae— II

Abstract The morphological features of all clades of neotropical Lecythidaceae subfam. Lecythidoideae (Brazil nut family) with actinomorphic androecia (Allantoma, Grias, Gustavia) as well as three clades with zygomorphic androecia (Cariniana, Couroupita, and Couratari) are described. These clades are those that were recovered by a phylogeny based on molecular data, and all, except Allantoma and Cariniana, have been recognized as genera without changes for over a hundred years. The latter two genera have recently been circumscribed such that they now also represent monophyletic clades; thus, the authors conclude that the clades discussed in this paper represent well-defined genera based on both morphological and molecular data. Morphological descriptions of these six clades of the non-Bertholletia clade are included and a key to the 16 clades of New World Lecythidaceae is presented. Introduction The use of anatomical, morphological, and molecular data to produce cladograms has advanced the study of neotropical Lecythidaceae. -
Recircumscription of the Lecythidaceae
TAXON 47 - NOVEMBER 1998 817 Recircumscription of the Lecythidaceae Cynthia M. Morton'", Ghillean T. Prance', Scott A. Mori4 & Lucy G. Thorburn' Summary Morton. C. M.• Prance, G. T., Mori, S. A. & Thorburn. L. G.: Recircumscriplion of the Le cythidaceae. Taxon 47: 817-827. 1998. -ISSN 004Q-0262. The phylogenetic relationships of the genera of Lecythidaceae and representatives of Scyto petalaceae were assessed using cladistic analysis of both molecular (rbcL and trnL se quences) and morphological data. The results show that the pantropical family Lecythida ceae is paraphyletic. Support was found for the monophyly of three of the four subfamilies: Lecythidoideae, Planchonioideae, and Foetidioideae. The fourth subfamily, Napoleonaeol deae, was found to be paraphyletic, with members of the Scytopetalaceae being nested within it forming a strong clade with Asteranthos. Both families share a number of mor phological features, including several distinct characters such as cortical bundles in the stem. The combined analysis produced three trees of 471 steps and consistency index Cl = 0.71 and retention index Rl = 0.70. Asteranthos !'P.~, members of Scytopetalaceae should be treated as a subfamily of Lecythidaceae, while Napoleonaea and Crateranthus (the latter based solely on morphological features) should remain in the subfamily Napoleo naeoideae.The Lecythldaceaeare recircumscribed, and Asteranthosand members of Scyto peta/aceae are included in Scytopetaloideae. A formal·llWJ!J-pmic synopsis accommodating this new circumscription is presented. Introduction The Lecythidaceae Poit, are 8 pantropical family of trees and shrubs consisting of . 20 genera split into four subfamilies in contemporary classifications (Cronquist, 1981; Prance & Mori, 1979; Takhtajan, 1987; ~ri & Prance, 1990; Thome, 1992). -
