Euphorbiaceae) A new Madagascan species of Hancea Seem. (Euphorbiaceae) Gordon McPHERSON Missouri Botanical Garden, P.O. Box 299, Saint Louis, MO, 63166-0299 (USA) [email protected] McPherson G. 2012. — A new Madagascan species of Hancea Seem. (Euphorbiaceae). Adansonia, sér. 3, 34 (1): 71-75. http://dx.doi.org/10.5252/a2012n1a8 KEY WORDS ABSTRACT Euphorbiaceae, A new species of the genus Hancea Seem. is described from the forested region Acalyphoideae, Hancea, of eastern Madagascar. It can be readily distinguished from the three species Mallotus, previously recognized on the island by the shape of its leaf apex and by its lack Deuteromallotus, Madagascar, of domatia in the axils of the leaf veins. A key to the species of the genus in new species. Madagascar is presented. MOTS CLÉS RÉSUMÉ Euphorbiaceae, Acalyphoideae, Une nouvelle espèce du genre Hancea Seem.

Light microscopic observations of paraffin- and plastic-embedded spec­ imens were complemented with scanning electron micrographs. Leaf anatomy of the four species is typical of large mesophytic plants. Aattened foliar nectaries are shown to be composed of specialized epidermal cells. The nonvascularized nectaries consist of narrow columnar cells each with a large nucleus, numerous vacuoles, and dense cytoplasm. Subglandular parenchyma cells have more pro­ nounced nuclei, more vacuoles and denser cytoplasm than do typical laminar parenchyma. Structurally, these nectaries are similar to those found in other taxa of Euphorbiaceae and in other families of flowering plants.

    Ethnobotanical Leaflets 14: 674-80, 2010. Ethnobotanical Observations of Euphorbiaceae Species from Vidarbha region, Maharashtra, India G. Phani Kumar* and Alka Chaturvedi# Defence Institute of High Altitude Research (DRDO), Leh-Ladakh, India #PGTD Botany, RTM Nagpur University, Nagpur, India *corresponding author: [email protected] Issued: 01 June, 2010 Abstract An attempt has been made to explore traditional medicinal knowledge of plant materials belonging to various genera of the Euphorbiaceae, readily available in Vidharbha region of Maharasthtra state. Ethnobotanical information were gathered through several visits, group discussions and cross checked with local medicine men. The study identified 7 species to cure skin diseases (such as itches, scabies); 5 species for antiseptic (including antibacterial); 4 species for diarrhoea; 3 species for dysentery, urinary infections, snake-bite and inflammations; 2 species for bone fracture/ dislocation, hair related problems, warts, fish poisons, night blindness, wounds/cuts/ burns, rheumatism, diabetes, jaundice, vomiting and insecticide; 1 species as laxative , viral fever and arthritis. The results are encouraging but thorough scientific scrutiny is absolutely necessary before being put into practice. Key words: Ethnopharmacology; Vidarbha region; Euphorbiaceae; ethnobotanical information. Introduction The medicinal properties of a plant are due to the presence of certain chemical constituents. These chemical constituents, responsible for the specific physiological action, in the plant, have in many cases been isolated, purified and identified as definite chemical compounds. Quite a large number of plants are known to be of medicinal use remain uninvestigated and this is particularly the case with the Indian flora. The use of plants in curing and healing is as old as man himself (Hedberg, 1987).

Ghogrey Science College, Dhule 424001, Maharashtra, India 2 Department of Biotechnology, Moolji Jaitha College, Jalgaon, 425 002, Maharashtra Abstract: Euphorbiaceae is among the large flowering plant families consisting of a wide variety of vegetative forms. Some of which plants are of great importance, It is need to explore traditional medicinal knowledge of plant materials belonging to various genera of Euphorbiaceae available in North Maharashtra State. Plants have always been the source of food, medicine and other necessities of life since the origin of human being. Plant containing ethnomedicinal properties have been known and used in some forms or other tribal communities of Satpuda region. These tribal have their own system of Ethnomedicine for the treatment of different ailments. In the course of survey useful Euphorbian plants of Satpuda, 34 medicinal plants belonging to 18 genus is documented. This article reports their botanical identity, family name, local language name part used preparations and doses, if any. It is observed that tribes of this region uses various Euphorbian plant in the form of decoction, infusion, extract, paste, powder etc. Thus the knowledge area of this region with respect to ethnomedicine would be useful for botanist, pharmacologist and phytochemist for further explorations. It is concluded that the family is a good starting point for the search for plant-based medicines.

Boerl. are very similar in appearance, with opposite leaves of which one large and elliptic, and the other reduced and more or less obcordate. However, a detailed look revealed enough differences to regard them as distinct species. Key words: Euphorbiaceae, Hancea, Mallotus. INTRODUCTION Mallotus Lour. is one of the larger genera in the Euphorbiaceae with c. 150 species, which are mainly found in Southeast Asia and the Malay Archipelago, but there are also some species in Africa and the Indian Ocean. The genus is divided into several sections of which some are distinct, but others appear to be poly- or paraphyletic (e. g., Slik & Van Welzen, 2001a). One well-defined section is Hancea. This group of species has opposite leaves of which one is reduced and stipule-like. This section only became really distinct after several species were excluded (Slik & Van Welzen, 2001b). Recent morphological studies (Sierra, pers. comm.) and phylogenetic analyses based on sequence data (Kulju, pers. comm.) show that section Hancea and the monotypic section Oliganthae (M.

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.

    Pak. J. Bot., 37(4): 785-796, 2005. POLLEN FLORA OF PAKISTAN-XLVII. EUPHORBIACEAE ANJUM PERVEEN AND M. QAISER Department of Botany, University of Karachi, Karachi Pakistan Abstract Pollen morphology of 40 species representing 6 genera viz., Andrachne, Chrozophora, Dalechampia, Euphorbia, Mallotus and Phyllanthus of the family Euphorbiaceae from Pakistan has been examined by light and scanning electron microscope. Euphorbiaceae is a eurypalynous family. Pollen grains usually radially symmetrical, isopolar, prolate-spheroidal to sub-prolate or prolate often oblate-spheroidal, colporate (tri rarely 6-7), colpi generally with costae, colpal membrane psilate to sparsely or densely granulated, ora la-longate, sexine as thick as nexine or slightly thicker or thinner than nexine. Tectal surface commonly reticulate or rugulate - reticulate rarely striate or verrucate. On the basis of exine pattern 5 distinct pollen types viz., Andrachne-aspera - type, Chrozophora oblongifolia-type, Euphorbia hirta-type and Mallotus philippensis - type and Phyllanthus urinaria - type are recognized. Introduction Euphorbiaceae, a family of about 300 genera and 7950 species is cosmopolitan in distribution, more especially in tropical and temperate regions (Willis, 1973; Mabberley, 1978). In Pakistan it is represented by 24 genera and 90 species (Radcliffe-Smith, 1986). Euphorbiaceae is one of the most diverse family, ranges from the herb, shrub and tall tree Hevea of the Amazonian rain forest to small cactus like succulents of Africa and Asia Herb, shrub and tree often with milky sap, leaves mostly alternate, flowers unisexual, ovary superior and usually trilocular. The family is of considerable economic importance for rubber plant (Hevea), castor oil (Ricinus communis), cassava and tapioca (Manihot) and tung oil (Aleurites fordi).

    BLUMEA 50: 275 –277 Published on 14 July 2005 http://dx.doi.org/10.3767/000651905X622996 LASIOCOCCA BREVIPES (EUPHORBIACEAE): A NEW COMBINATION P.C. VAN WELZEN & S.E.C. SIERRA Nationaal Herbarium Nederland, Universiteit Leiden branch, P.O. Box 9514, 2300 RA Leiden, The Netherlands e-mail: [email protected]; [email protected] SUMMARY Lasiococca brevipes (Merr.) Welzen & S.E.C. Sierra is a new combination based on Mallotus brevipes Merr. The new combination replaces Lasiococca malaccensis Airy Shaw, which appears to be a later synonym. The species is very rare, but widespread and seemingly with a very disjunct distribution, found in Sumatra, the Philippines, Sulawesi, and the Lesser Sunda Islands. Key words: Lasiococcus, Euphorbiaceae, Malesia, Philippines. INTRODUCTION A recent revision of Mallotus Lour. (Euphorbiaceae) resulted in finding a few odd Philippine specimens, identified under various names: Mallotus resinosus (Blanco) Merr., Mallotus muricatus Müll.Arg. (name a synonym of M. resinosus), and Mallotus brevipes Merr. The material identified as M. muricatus (R.S. Williams 2968) appeared to be isotypes of M. brevipes (Merrill, 1914). The specimens have whorled to subopposite leaves (terminal leaves opposite), they lack glandular and stellate hairs (typical for Mallotus), the petiole is very short, the leaf base narrowly heart-shaped, and the ovary/fruits have short papillae with a single to a few long, sharp pointed hairs. The specimens with staminate flowers show branching stamens. This combination of characters is typical for Lasiococca Hook.f. Lasiococca was recently revised (Van Welzen, 1998). The genus is difficult to recog- nise, a synonym of L. comberi Haines was even described in the Celastraceae: Euonymus auriculatus Craib (Van Welzen, 2002).
