Morphological and Anatomical Study of Bidens Pilosa Var.Pdf (440.3
1 Morphological and Anatomical Study of Bidens pilosa var. minor (Blume.) Sher. From Tribe Heliantheae Dr Ngu Wah Win1 & Min Htay Wai Linn2 Abstract In this research, morphology and anatomy of Bidens pilosa var. minor (Blume) Sher. of tribe Heliantheae belonging to the family Asteraceae were studied, photomicrographed and described. The plant is annual erect herb. Leaves are trifoliolate compound and the florets of rays and disc in a head are bisexual and monoecious heads are also found. In anatomical characters, although endodermis are inconspicuous only in roots, it is conspicuous in stem and root. The stomata types are anomocytic and vascular bundles are bicollateral, open and covered by one-layer of bundle sheath. The resulting characters are valuable for the identification of study species for further researchers. Key words – Asteraceae, endodermis, vascular bundles, bicollateral Introduction Asteraceae also called Sunflower family is one of the most important economic family and the second largest of flowering plant families. It consists of several tribes. Its flowers have two types of florets. Disc florets are in the center of head and ray florets in the outer. Many plants of Asteraceae family are economically important as weed, ornamentals, medicinal, green vegetables and poisonus plants. Commercially the flowers of this Asteraceae family are very famous of their colourful florets and beautiful petals. Several plants of this family are commonly cultivated for ornamental purpose in the gardens plots and field. The studied species of this Asteraceae family are native of America, Africa, India and all warmer countries (Grierson 1980). The study species is widely distributed in Pyin Oo Lwin of Mandalay Region. -

Hellmuth Maya Ethnobotany Complete Inventory of plants 2 Introduction This opus is a progress report on over thirty years of studying plants and agriculture of the present-day Maya with the goal of understanding plant usage by the Classic Maya. As a progress report it still has a long way to go before being finished. But even in its unfinished state, this report provides abundant listings of plants in a useful thematic arrangement. The only other publication that I am familiar with which lists even close to most of the plants utilized by the Maya is in an article by Cyrus Lundell (1938). • Obviously books on Mayan agriculture should have informative lists of all Maya agricultural crops, but these do not tend to include plants used for house construction. • There are monumental monographs, such as all the trees of Guatemala (Parker 2008) but they are botanical works, not ethnobotanical, and there is no cross-reference by kind of use. You have to go through over one thousand pages and several thousand tree species to find what you are looking for. • There are even important monographs on Maya ethnobotany, but they are usually limited to one country, or one theme, often medicinal plants. • There are even nice monographs on edible plants of Central America (Chízmar 2009), but these do not include every local edible plant, and their focus is not utilitarian plants at all, nor sacred plants. -
V. Munnozia Ortiziae (Liabeae), a New Species from the Andes of Pasco, Peru
Pruski, J.F. 2012. Studies of Neotropical Compositae–V. Munnozia ortiziae (Liabeae), a new species from the Andes of Pasco, Peru. Phytoneuron 2012-2: 1–6. Published 1 January 2012.

Box 299 St. Louis, Missouri 63166 ABSTRACT A new species, Munnozia ortiziae Pruski (Compositae: Liabeae: Munnoziinae), is described from the Andes of Pasco, Peru. It is most similiar to M. oxyphylla , also of Peru, in its pinnately veined, lanceolate to elliptic-lanceolate leaves and moderately large capitula in loose, open cymose capitulescences. KEY WORDS: Andes, Asteraceae, Compositae, Liabeae, Liabum , Munnozia , Munnoziinae, Pasco, Peru. Munnozia Ruiz & Pav. (Compositae: Liabeae: Munnoziinae) is an Andean-centered genus of more than 40 species (Robinson 1978, 1983). It was resurrected from synonymy of Liabum Adans. by Robinson and Brettell (1974) and differs from Liabum by black (vs. pale) anther thecae. A new species, Munnozia ortiziae Pruski, from the Andes of Pasco, Peru, is described herein. The new species appears most similar to M. oxyphylla (Cuatrec.) H. Rob., which is known from Huánuco and Pasco, Peru. MUNNOZIA ORTIZIAE Pruski, sp. nov. TYPE : PERU. Pasco. Prov. Oxapampa. Dist.

Extensive research on the domestication and rubber content of TK has demonstrated TK’s potential in industrial applications as a relevant natural rubber and latex-producing alternative crop. However, many aspects of its biology have been neglected in published studies. For example, floral development is still poorly characterized. TK inflorescences were studied by scanning electron microscopy. Nine stages of early inflorescence development are proposed, and floral micromorphology is detailed. Individual flower primordia development starts at the periphery and proceeds centripetally in the newly-formed inflorescence meristem. -

Academic Editor: Reinhard Länger Received: 18 August 2015; Accepted: 27 May 2016; Published: 27 May 2016 Abstract: The value of root and rhizome anatomy for the taxonomic characterisation of 59 species classified into 34 genera and 12 subtribes from the Asteraceae tribes Cardueae and Cichorieae was assessed. In addition, the evolutionary history of anatomical characters was reconstructed using a nuclear ribosomal DNA sequence-based phylogeny of the Cichorieae. Taxa were selected with a focus on pharmaceutically relevant species. A binary decision tree was constructed and discriminant function analyses were performed to extract taxonomically relevant anatomical characters and to infer the separability of infratribal taxa, respectively. The binary decision tree distinguished 33 species and two subspecies, but only five of the genera (sampled for at least two species) by a unique combination of hierarchically arranged characters. Accessions were discriminated—except for one sample worthy of discussion—according to their subtribal affiliation in the discriminant function analyses (DFA). However, constantly expressed subtribe-specific characters were almost missing and even in combination, did not discriminate the subtribes. -

736 Part 4 The History of Life How are developmental biology and evolution related? Developmental biol- ogy is the study of the processes by which an organism grows from zygote to reproductive adult. Evolutionary biology is the study of changes in populations across generations. As with non-shattering cereals, evolutionary changes in form and function are rooted in corresponding changes in development. While evo- lutionary biologists are concerned with why such changes occur, developmental biology tells us how these changes happen. Darwin recognized that for a com- plete understanding of evolution, one needs to take account of both the “why” and the “how,” and hence, of the “important subject” of developmental biology. In Darwin’s day, studies of development went hand in hand with evolution, as when Alexander Kowalevsky (1866) first described the larval stage of the sea squirt as having clear chordate affinities, something that is far less clear when examining their adults. Darwin himself (1851a,b; 1854a,b) undertook extensive studies of barnacles, inspired in part by Burmeister’s description (1834) of their larval and metamorphic stages as allying them with the arthropods rather than the mollusks. If the intimate connection between development and evolution was so clear to Darwin and others 150 years ago, why is evolutionary developmental biology (or evo-devo) even considered a separate subject, and not completely inte- grated into the study of evolution? The answer seems to be historical. Although Darwin recognized the importance of development in understanding evolution, development was largely ignored by the architects of the 20th-century codifica- tion of evolutionary biology known as the modern evolutionary synthesis. -
