Also, natural products have reminded diverse scientists to take a delight in their medical and insecticidal applications linked to the environmental. A variety of metabolites have a defensive function for the plants. Thus, three spontaneous plants: Caroxylon imbricatum, Tetraena alba and Cotula cinerea collected from two ecotypes and analyzed by two known conventional methods:Gas Chromatography‐Mass Spectrometry GC QTOF(quadrupole time of flight )_MS and Liquid Chromatography-Mass spectrometry LCQTOF(quadrupole time of flight )_MS. The investigation conducted out on the identification and quantification of metabolites revealed the main metabolites which have biological activities as a part of an alternative Citation:Lastname, F.; Lastname, F.; to synthetic insecticides.

A total vascular flora of 88 species belonging to 44 families and 76 genera was recorded from the island. The dominant families of the flora are Euphorbiaceae, Papilionaceae, Moraceae, Rutaceae and Rubiaceae etc. Most of the genera in the flora are tropical characteristic. In the island, there are few endemic species, which may be due to its young flora in geological respect. The vegetation are mainly classified as the evergreen broad-leaved forests, scrub forests and beach vegetation. It is urgent to protect biodiversity in limestone regions and how to deal with the relationship between development and protection is still a difficult task. Introduction Gulf of Tonkin.

Resurrection of <I>Hancea</I> and Lectotypification of <I>Adisca</I
BLUMEA 52: 361–366 Published on 30 October 2007 http://dx.doi.org/10.3767/000651907X609106 RESURRECTION OF HANCEA AND LECTOTYPIFICATION OF ADISCA (EUPHORBIACEAE) S.E.C. SIERRA, K.K.M. KULJU, J.F. VELDKAMP & P.C. VAN WELZEN Nationaal Herbarium Nederland, Universiteit Leiden branch, P.O. Box 9514, 2300 RA Leiden, The Netherlands; e-mail: [email protected] SUMMARY Based on phylogenetic studies with DNA sequence data, the formerly monotypic genus Cordemoya was recently expanded with 16 additional species previously assigned to Mallotus. However, the earliest legitimate generic name available is Hancea, and, therefore, Cordemoya is here reduced to Hancea (20 new combinations are proposed). Subsequently, the subgenus and section Diplochlamys from Asia are renamed to Hancea. Additionally, the genus Adisca is lectotypified with Adisca flori bundus (= Mallotus floribundus). Key words: Euphorbiaceae, Adisca, Cordemoya, Diplochlamys, Hancea, Mallotus, Madagascar, Malesia, Mascarenes. INTRODUCTION Based on a well-supported clade obtained with DNA sequence data (Kulju et al., 2007, f. 2), the genus Cordemoya Baill. (formerly monotypic with C. integrifolia (Willd.) Baill. from the Mascarene Islands as single species) was expanded by Sierra et al. (2006) with sixteen additional species previously assigned to Mallotus Lour. Pollen and leaf anatomical studies revealed characters that are important for the delimitation of both genera. Cordemoya can be distinguished by the presence of pollen ornamenta- tion with scabrae and by capitate glandular hairs with multicellular stalks and sessile peltate-stellate hairs with a central cell, while Mallotus is recognized by the presence of a perforate/micro-reticulate pollen ornamentation with scabrae and by spherical to disc-shaped multicellular glandular hairs. -

Bailey Hortorium, Department of Plant Biology, 412 Mann Library Building, Cornell University, Ithaca, NY 14853, U.S.A. *Corresponding author; e-mail: [email protected] ABSTRACT We report fossil wood specimens from two Miocene sites in Panama, Central America: Hodges Hill (Cucaracha Formation; Burdigalian, c.19 Ma) and Lago Alajuela (Alajuela Formation; Tortonian, c.10 Ma), where material is preserved as calcic and silicic permineralizations, respectively. The fossils show an unusual combination of features: diffuse porous vessel arrangement, simple perforation plates, alternate intervessel pitting, vessel–ray parenchyma pits either with much reduced borders or similar to the intervessel pits, abundant sclerotic tyloses, rays markedly heterocellular with long uniseriate tails, and rare to absent axial parenchyma. This combination of features allows assignment of the fossils to Malpighiales, and we note similarities with four predominantly tropical families: Salicaceae, Achariaceae, and especially, Phyllanthaceae, and Euphorbiaceae. -

Gilbert Coelodiscus Baillon; Echinus Loureiro; Rottlera Roxburgh. Trees or shrubs, rarely climbers, usually dioecious; indumentum usually of simple and stellate hairs, and whitish to reddish glandular scales. Leaves alternate or opposite with one member of pair smaller; stipules usually subulate; leaf blade undivided or lobate, sometimes peltate, abaxially often glandular-scaly, adaxially often distinctly glandular, base usually with 2 or more glands, venation palmate or pinnate. Inflorescences terminal or axillary, mostly unbranched, less often branched, usually many flowered. Male flowers usually several per bract; calyx 3–5-partite, valvate; petals and disk absent; stamens 15–250; filaments free; anthers 2-locular, connective often broad; pistillode absent [or rarely present]. Females flowers 1(or 2) per bract; calyx 3–5-lobed, sometimes spathaceous and caducous; ovary (2 or)3(or 4)-locular; styles simple, plumose or long papillose; ovules 1 per locule. Capsule (2 or)3(or 4)-locular, smooth or softly spiny. Seeds subglobose or ovoid, smooth, sometimes with aril. About 150 species: tropical and subtropical regions in Asia, a few species in Africa and Australia; 28 species (seven endemic) in China. Phylogenetic studies (Sierra et al., Blumea 51: 519–540. 2006; Kulju et al., Blumea 52: 115–136. 2007) have revealed that Mallotus and Macaranga are closely related and that the species of Cordemoya are distinct from both. These also show that Trevia is embedded within Mallotus but its inclusion has serious nomenclatural consequences and so this is not followed here until the situation is resolved. -
A TAXONOMIC Revision of Mallotus SECTION Philippinenses (FORMER SECTION ROTTLERA – Euphorbiaceae) in Malesia and THAILAND
BLUMEA 50: 221– 248 Published on 14 July 2005 http://dx.doi.org/10.3767/000651905X622978 A TAXONOMIC REVISION OF MALLOTUS SECTION PHILIPPINENSES (FORMER SECTION ROTTLERA – EUPHORBIACEAE) IN MALESIA AND THAILAND S.E.C. SIERRA, P.C. VAN WELZEN & J.W.F. SLIK Nationaal Herbarium Nederland, Universiteit Leiden branch, P.O. Box 9514, 2300 RA Leiden, The Netherlands SUMMARY A revision of Mallotus section Philippinenses (former section Rottlera) in Malesia and Thailand is given. Descriptions, distribution maps, habit drawings, and a key to the species are provided. The diagnostic characters for the section are briefly discussed. Five species (M. kongkandae, M. lepto stachyus, M. pallidus, M. philippensis, and M. repandus) are recognised. Mallotus chromocarpus is excluded from the section because it has more shared characters with the monospecific genus Octo spermum, like the presence of indehiscent fruits, absence of stipules, marginal extrafloral nectaries on the upper side of the leaf blade, broad connectives (shaped umbrella-like), and its occurrence in New Guinea, and is therefore probably closely related to it. Key words: Euphorbiaceae, Rottlerinae, Mallotus, Philippinenses, Rottlera, Octospermum, Malesia, taxonomy. INTRODUCTION Mallotus Lour. is a genus of shrubs, trees, and climbers, with c. 150 species. It is classi- fied in the subfamily Acalyphoideae, subtribe Rottlerinae (Euphorbiaceae s.s.), together with six other genera: Avellanita, Cordemoya, Neotrewia, Octospermum, Rockinghamia, and Trewia (Radcliffe-Smith, 2001). Mallotus is mainly found in (sub)tropical Asia, Australia, and the Pacific, with only a few species in tropical Africa and Madagascar (Webster, 1994). The genus Mallotus was first described by De Loureiro (1790). He included only one species (Mallotus cochinchinensis), which is a synonym of Mallotus paniculatus (Lam.) Müll.Arg. -

Inflorescences axillary or terminal, flowers in cymes or fascicles, these often arranged along an elongated axis, branched or unbranched, forming a thyrse, in congested heads, or in a flowerlike cyathium with very reduced flowers enclosed within a ± cupular involucre; bracts sometimes petaloid. Flowers unisexual, within same inflorescence or in separate inflorescences, actinomorphic. Sepals (1–)3–6(–8), free or connate into calyx tube, valvate or imbricate, rarely absent (Euphorbia). Petals free, often reduced or absent. Disk present or absent. Male flowers with disk intrastaminal or extrastaminal, entire to dissected. Stamens one to very many, hypogynous; filaments free or connate; anthers 2(–4)-locular, mostly dehiscing longitudinally, rarely transversely or by pores, introrse or extrorse; rudimentary ovary sometimes present.
