  • Comparison of Different Classifications on the Celastraceae
    UNITED STATES DEPARTMENT OF AGRICLJLTURE AGRICULTURAL RESEARCH SERVICE NORTHEASTERN REGlON AGRICULTURAL RESEARCH CENTER BELTSVILLE. MARYLAND 20705 Novenber 7, 1974 / Subject: ConpadSon of Different Classifications on the Celastraceae in Africa with Discussions on the Status of Gymnosporia and Other Genera To : R. E. Perdue, Jr., Chief ,.. Medicinal Plant Resources ~aboratory Currently, the taxonomy of the Celastraceae is in a state of confusion. A few recent revisions limited mostly ,to political boundaries, have helped to clarify the systematics in a few genera; however, the continued disagreement among generic relationships seems to make it nore difficult for the non-specialist. Because of special efforts to procure plant samples in this family, frequent synonomy has led to confusion as well as duplica- tion, especially in Africa where a number of samples have been received from floristically related countries in which different authorities are recogcized for the Celastracean Flora. This report, primarily, will 'deal with the systematic problems of the African Celasrrtseae. Until recently, the Hippocrateaceae was treated as a separate family from the Celastraceae (Smith, 1940; Loesener, 1942; Wilczek, 1960; Hallee, 1962). L Robson (1965, 1966), Ding Hou (1963, 1964), Blakelock (1958), and Codd (1972) have united the Hippocrateaceae with the Celastraceae; but, their reasons for uniting the two families are not in agreement. The Celastraceae is believed by Codd and Kobson to comprise about 60 to 70 genera, but Ding Hou has indicated that there are about 90 genera. For the purpose of identifying two major complexes, which taxonomists are not in agreement, I will refer to the Celastraceae and Hippocrateaceae as two separate families.

    BOTANY Proceedings C 88 (4), December 16, 1985 New species and notes on genera of the Celastraceae (incl. Hippocrateaceae). III by A.M.W. Mennega Instiluut voor Systematische Plantkunde, Heidelberglaan 2, Utrecht, the Netherlands Communicated by Prof. F.A. Stafleu at the meeting of February 25, 1985 ABSTRACT A description is given of two new species in the genus Pristimera, P. dariense from Panama and P. caudata from Suriname. P. dariense differs by its flattened disk from the other New World species of the genus, but would fit in the subgenus Trochantha N. Hallé known from Africa. Cuervea crenulata sp. nov. is a species collected in Brazil, Minas Gerais. Another species in Cuervea, C. mitchellae (Johnst.) A.C. Smith is considered as a synonym of C. kappleriana. Hylenaea unguiculata sp. nov. is a new species from Suriname. The material on which the new species is based was at first erronously ascribed to the genus Tonteleawith remarkably similar flowers.

Av. Bandeirantes, 3900 - CEP 14040-901, Ribeirão Preto, São Paulo, Brasil Abstract – (Flora of the Serra do Cipó, Minas Gerais: Celastraceae sensu lato). The study of the family Celastraceae is a part of the project of "Flora of Serra do Cipó, Minas Gerais, Brazil". In its most recent delimitation, Celastraceae sensu lato encompass the Hippocrateaceae, a group already addressed in a previous survey to the Serra do Cipó, the later with three genera (Cheiloclinium , Peritassa and Tontelea), with four species. To these taxa are now summoned the species of Celastraceae sensu stricto, with the genus Maytenus (seven species), and Plenckia (one species), besides two species representing two genera (Pristimera and Salacia) of traditional Hippocrateaceae collected after the publication of the Hippocrateaceae survey. As a summary, Celastraceae sensu lato is represented in Serra do Cipó by seven genera and 14 species. Keys are presented to the genera and species of Celastraceae sensu lato, as well as descriptions, illustrations and comments on the geographic distribution, phenology and variability of the species of Celastraceae sensu stricto (previously untreated). Comments and an updated list of exsiccate of “Hippocrateaceae” are also provided. Additionally, we propose the synonymy of Maytenus salicifolia Reissek under M. gonoclada Mart. Key words: Hippocrateaceae, floristics, campo rupestre vegetation, Espinhaço Range. Resumo – (Flora da Serra do Cipó, Minas Gerais: Celastraceae sensu lato).

  • Unanimously with the Celastraceae, Because of Its Arboreous Habit, Capsular Fruit, and Isomerous St Amens
    Celastraceae—II Ding HouLeyden) The family Hippocrateaceae was established by A. L. DE JUSSIEU (Ann. Mus. Hist. Nat. Paris 18, later R. BROWN 1811, 486, as Hippocraticeae) and three years created the family Celastraceae (in Flinders, Voy. Terra Austr. 2, 1814, 554, as Celastrineae). BROWN was well aware that his new ‘order’ (family in our sense) closely approached Hippocrateaceae and hinted at the Possibility that they might be fused later. This indeed effected P1. who was by HOOKER f. (in B. & H. Gen. 1, 1862, 358), reduced to Hippocrateaceae a tribe of the Celastraceae. Still up till the present there has been no un- animity of opinion on this question. Disagreement with HOOKER’S vision started with MIERS (Trans. Linn. Soc. 38, 1873,319-330) in his elaborationof the South American Hippocrateaceae; reviewed the history of the two families and ably summarized their general characters, Basing himself on literature and new observations he put forward eleven points of difference f or their distinction. However, many new genera and species have been described since 1873 Which have obliterated many of MIERS'S arguments, and recent specialists agree that, if any, only few characters do hold. Loesener, who kept the two families apart (in E. & P. Pfl. Earn. 3, 5, 1892, 189-230; ibid. E D. 2, 20b, 1942, 87-231), in discussing the African genus Campylostemon WELW. (Notizbl. & e rl.-Dahl. 13, 1937, 563-577) remarked that the chief difference between the families would e : isomerous flowers in Celastraceae and anisomerous flowers in Hippocrateaceae. In passing 11 may be noted here that, in absence of fruit, he referred Campylostemon, which possesses 5 stamens, to the Celastraceae.

    IAWA Journal, Vol. 18 (4), 1997: 331-368 WOOD ANATOMY OF THE HIPPOCRATEOIDEAE (CELASTRACEAE) by Alberta M.W. Mennega Department of Plant Ecology & Evolutionary Biology, Herbarium Division, University of Utrecht, Heidelberglaan 2, P. O. Box 80.102,3508 TC Utrecht, The Netherlands SUMMARY In this paper the wood anatomy of the subfarnily Hippocrateoideae of the Celastraceae is treated. Halle's division (1986, 1990) of the subfarnily into four tribes, chiefly based on material of tropical Africa: viz. Salacieae, Campylostemoneae, Helictonemeae and Hippocrateae is followed. In a recent issue of the Flora of the Guianas the Hippocrateaceae - there treated as aseparate farnily - were divided into Hippocrateoideae and Salacioideae. This bipartition was reflected in the wood structure of the genera studied (Mennega 1994). Here the wood structure of all gen­ era worldwide (24), except the Asian genus Arnicratea, is described. It appeared that again a subdivision into two distinct anatomical groups could be made, with the three last tribes mentioned above showing the same characteristic structure as found before in New World Hippocra­ teae/Hippocrateoideae. The most important features of this group are the presence of very wide and very high rays, in a number of genera with unlignified ray cells at the growth ring border, the absence of included phloem tissue, and in many species an intruding bark resulting in an in­ dented wood pattern in stern cross sections or even an intricate pattern of deep furrows. The Salacieael Salacioideae on the other hand are char­ acterized by narrow, not exceptionally high rays, absence of unlignified ray cells, the occurrence of septate fibres in a parenchyma-like dis­ tribution, and often by the presence of included phloem tissue, either as isolated strands or more often as conspicuous concentric bands, or as ir­ regular bands with radial connections.

Mole National Park, Top of Konkori Scarp near Konkori Camp (Photo K. Schmitt 22.02.1993). PREFACE The area now occupied by Mole National Park was heavily populated before 1870 but has never been densely populated since and protection began in 1958. To date human impact - with the exception of poaching - has been fairly limited. The dominant vegetation type is open savanna woodland (Guinea savanna), most of which is burnt annually. Mole National Park f therefore represents an undisturbed typical Guinea savanna ecosystem of substantial size (4 840 km2). Fire is not considered as a disturbance to a savanna ecosystem, but plays an integral part in r its perpetuation. "There is good evidence that fire in vegetation is a phenomenon of great antiquity, antedating the arrival of man by many millions of years ... but it was not until the arrival of man that fire assumed an importance comparable to existing climatic factors in shaping the composition, structure and distribution of plant communities and thereby, the r animal populations with which they are inseparably linked." (Rose Innes 1972, p. 147). The effective long-term management and protection of th.is important ecosystem requires scientific baseline data and ongoing research and monitoring.
