The beginning open access print & e journal, peer of history of use of anatomical data in taxonomy can be traced back to reviewed, worldwide Malpighi (1675-1679).Since then, anatomical data has been used and abstract listed, culminated in the most recent works of Metcalfe and Chalk (1950, published every month with ISSN, RNI Free- 1979).Anatomical evidence adds another string to the taxonomists bow, and membership, strengthens the summation of evidence that may be essential in the solution of downloads and access. significant problems, Bailley (1953).Leaves provide many anatomical characters (c.f.Robinson, 1969; Lackey, 1978 Keating, 1984…etc.).The http://lifesciencesleaflets.ning.com/ PEER-REVIEWED Page | 29 Life Sciences Leaflets FREE DOWNLOAD ISSN 2277-4297(Print) 0976–1098(Online) present authors provided anatomical evidence forthe Celastrales, a much loose - knit assemblage of plants (Shisode and Patil, 2000, 2005, 2008 a ,b, 2009, 2010, 2011).This paper deals with foliar anatomy of some species of Hippocrateaceae(sensu stricto) from taxonomic point of view. MATERIALS AND METHOD: The plant materialsobtainedfrom Surinam herbarium, Heidalberglaan, The Netherland. The herbarium material were first boiled in water for few minutes and few drops of acetic acid were added to soften and to help recovery of tissues to natural state .With a gap of few minutesafter boiling the materials were washed in water and kept for next stage of operation. Free hand sections of leaf lamina were taken .They were stained in safranin (1%) and light green (1%) combination and mounted in D.P.X after the customary method of dehydration (Paliwal,1974).They were studied under Olympus research microscope and sketches were drawn using camera lucida. They were inked by rotoring isograph pens. In some cases red, blue yellow filters were used for clarification. Types of stomatal ledges are after Rajagopal and Ramayya (1979). RESULTS AND DISCUSSION: The leaves are generally dorsiventral in the species studied; however, they are reported centric in Hippocratea and Salacia (Metcalfe and Chalk, 1950).They are always hypostomatic. The abaxial epidermal cells are larger than adaxial inAnthodon decussatum, Elachyptera floribunda, whereas the adaxial cells are smaller in Prionostemma aspera and Semialarium mexicanum.Epedermal cells on both sides are more or less equal-sized in Cuervea kappleriana and Tontelea glabra.The cuticle is thick on adaxial side than abaxial in Anthodon decussatum, Cheiloclinium cognatum, Cuervea kappleriana and Semialarium mexicanum. The epidermis is interrupted by unicellular and multicellular trichomes in Prionostemma aspera and Semialarium mexicanum. The guard cells with outer ledge (Group I, Type IV sensu Rajagopal,T, and Ramayya, 1979) is observed in Elachyptera floribunda andPrionostemma aspera, in rest others they belong to Group I ,Type I. The palisade is usually two layered, exceptionally single layered in Prionostemma aspera and three layered in Cuervea kappleriana.The region of spongy tissueis broader than the palisade region. In the midrib region, the hypodermis is generally chlorenchymatous. It is mostly two layered. It is collnchymatous and three layered on both sides Anthodon decussatum andTontelea glabra it is described one or two layered commonly beneath of the adaxial side of leaf in Campylostemon, Hippocratea and Salacia (Metcalfeand Chalk 1850). The vascular bundle is generally collateral. It is in the form of an arc in Anthodon decussatum which is capped by patches of sclerenchyma abaxially. It is generally in the form of continuous cylinder in Cheiloclinium cognatum, Cuervea kappleriana, Elachyptera floribunda, Prionostemma aspera; Semialarium mexicanum and Tontelea glabra .It is completely encircled by sclerenchyma from outside two cortical bundles are observed on http://lifesciencesleaflets.ning.com/ PEER-REVIEWED Page | 30 Life Sciences Leaflets FREE DOWNLOAD ISSN 2277-4297(Print) 0976–1098(Online) either side of vascular bundle of the midrib region inAnthodon decussatum, Cheiloclinium cognatum and Cuervea kappleriana. The pith is mostly wide and parennchymatous. It is narrow in Prionostemma aspera. In Anthodon decussatum, it is continuouswith cortical region adaxially. The sclereids are also dispersed in the cortical region only in Cheiloclinium cognatum. Lactiferous canals are described in the species of Hippocratea,Salacia, andCampylostemon (c.f.Metcalfe and Chalk, 1950) but are wanting in the species of present account .Mucilage cells in the mesophyll in case of Hippocratea Velutina and clustered crystals which are reported common by Metcalfe and Chalk (1950) are not observed inthe species presently investigated.

  • 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.

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).

In his gentle way, he has shepherded me away from dozens of unpro- ductive dark alleys, and encouraged me to head out independently toward the edge of scientific knowledge. He is one of a kind. I thank my graduate committee. Discussions with Richard Stevens, Jim Cronin, Jay Geaghan, and Thomas Dean sharpened the arguments forwarded in this dissertation.

  • 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.
