11-FLOWER DIAGRAMES, FORMULAS and FLOWER SYMETRY FLOWER FORMULAS and DIAGRAMES
11-FLOWER DIAGRAMES, FORMULAS AND FLOWER SYMETRY FLOWER FORMULAS and DIAGRAMES 1. FLOWER FORMULAS Floral formula is a means to represent the structure of a flower using numbers, letters and various symbols, presenting substantial information about the flower in a compact form. It can represent particular species, or can be generalized to characterize higher taxa, usually giving ranges of organ numbers. Floral formulae are one of the two ways of describing flower structure developed during the 19th century, the other being floral diagrams. Apart from the graphical diagrams, the flower structure can be characterized by textual formulae. A floral formula consists of five symbols indicating from left to right: Floral Symmetry Number of Tepal Number of Sepals Number of Petals Number of Stamens Number of Carpels Tepals Sepals Patals Stamen Carpels P K C A G The parts of the flower are described according to their arrangement from the outside to the inside of the flower. If an organ type is arranged in more whorls, the outermost is denoted first, and the whorls are separated by “+”. If the organ number is large or fluctuating, is denoted as “∞”. 2. FLOWER DIAGRAMES Floral diagram is a graphic representation of flower structure. It shows the number of floral organs, their arrangement and fusion. Different parts of the flower are represented by their respective symbols. Rather like floral formulas, floral diagrams are used to show symmetry, numbers of parts, the relationships of the parts to one another, and degree of connation and/or adnation. Such diagrams cannot easily show ovary position. FLOWER SYMMETRY Floral symmetry describes whether, and how, a flower in particular its perianth, can be divided into two or more identical or mirror-image parts.

Sample Chapter
CHAPTER 2 Description of Plants PRINCIPLES OF PLANT DESCRIPTION HABIT: Natural locality of plants. • Ornamental plants: Plants cultivated for its beauty rather than its use. e.g. Marigold, Gladiolus etc. • Food crop: For economic use e.g. Maize, Rice, Apple etc. • Wild crop: Grow or produced without human care. e.g. Wild rice (Zizania aquatica), Wild rye (Elymus spp.). HABITAT: Place where a plant lives and grows. • Annual: Occurring every year. e.g. Rice, Brinjal etc. • Biennial: Occurring every two years. e.g. Raddish, Turnip etc. • Perennial: Present in all seasons of year i.e. continual. e.g. Mango, Rose etc. NATURE: Inherent or basic character. • Herb: Bushy, non-woody, erect, prostrate and decumbent. e.g. Mint, Hyacinth etc. • Shrub: Several stemmed, medium-sized woody plant. e.g. Jasmine, Rose etc. • Tree: Stout, woody trunk with few or no branches on its lower part, perennial. e.g. Mango, Pine, Banyan etc. • Clums: Nodes and internodes clearly visible. e.g. Bambusa These may be a) Deciduous—Falling off leaves annually. b) Evergreen—Having foliage leaves which remain green. c) Perennial—Persists for several years. Root Organ of a plant which grows downwards, away from light and towards water. It doesn’t bear leaves and buds but has protective apex called root cap. 10 Introduction to Pharmacognosy • Assimilatory root: Roots become green and serve for photosynthesis. e.g. Trapa • Tuberous root: Swollen, root without any definite shape. e.g. Sweet potato • Fasciculated root: Several tuberous roots occur in cluster at the base of stem. e.g. Dahlia • Nodulous root: Tuberous root becomes suddenly swollen at apex.

JUDD W.S. Et. Al. (1999) Plant Systematics
CHAPTER8 Phylogenetic Relationships of Angiosperms he angiosperms (or flowering plants) are the dominant group of land Tplants. The monophyly of this group is strongly supported, as dis- cussed in the previous chapter, and these plants are possibly sister (among extant seed plants) to the gnetopsids (Chase et al. 1993; Crane 1985; Donoghue and Doyle 1989; Doyle 1996; Doyle et al. 1994). The angio- sperms have a long fossil record, going back to the upper Jurassic and increasing in abundance as one moves through the Cretaceous (Beck 1973; Sun et al. 1998). The group probably originated during the Jurassic, more than 140 million years ago. Cladistic analyses based on morphology, rRNA, rbcL, and atpB sequences do not support the traditional division of angiosperms into monocots (plants with a single cotyledon, radicle aborting early in growth with the root system adventitious, stems with scattered vascular bundles and usually lacking secondary growth, leaves with parallel venation, flow- ers 3-merous, and pollen grains usually monosulcate) and dicots (plants with two cotyledons, radicle not aborting and giving rise to mature root system, stems with vascular bundles in a ring and often showing sec- ondary growth, leaves with a network of veins forming a pinnate to palmate pattern, flowers 4- or 5-merous, and pollen grains predominantly tricolpate or modifications thereof) (Chase et al. 1993; Doyle 1996; Doyle et al. 1994; Donoghue and Doyle 1989). In all published cladistic analyses the “dicots” form a paraphyletic complex, and features such as two cotyle- dons, a persistent radicle, stems with vascular bundles in a ring, secondary growth, and leaves with net venation are plesiomorphic within angio- sperms; that is, these features evolved earlier in the phylogenetic history of tracheophytes.

Mr.Hameedullah kakar M.sc: scholar (botany) university of Baluchistan session:2017-2018 FLOWER DESCRIPTION SOME IMPORTANT TERMS Parts of Flowers • The pistil has three parts: stigma, style, and ovary. • The stigma is the sticky surface at the top of the pistil; it traps and holds the pollen. • The style is the tube-like structure that holds up the stigma. • The style leads down to the ovary that contains the ovules. Classification of FLOWERS: • Complete: flowers possessing petals and sepals • Incomplete: flowers possessing either petals or sepals • Perfect: flowers containing both pistil and stamen • Imperfect: flowers containing either the pistil or stamen Parts of Flowers • A complete flower has a stamen, a pistil, petals, and sepals. • An incomplete flower is missing one of the four major parts of the flower, the stamen, pistil, petals, or sepals. Parts of Flowers • Flowers can have either all male parts, all female parts, or a combination. • Flowers with all male or all female parts are called imperfect (cucumbers, pumpkin and melons). • Flowers that have both male and female parts are called perfect (roses, lilies, dandelion). Students are to illustrate the following: • Complete/ Perfect Flower • Incomplete/Perfect Flower • Complete/ Imperfect Flower • Incomplete/ Imperfect Flower Types of Flowers: • As previously mentioned, there are plants which bear only male flowers (staminate plants) or bear only female flowers (pistillate plants). • Species in which the sexes are separated into staminate and pistillate plants are called dioecious. • Most holly trees and pistachio trees are dioecious; therefore, to obtain berries, it is necessary to have female and male trees. Types of Flowers: • Pistillate (female) flowers are those which possess a functional pistil(s) but lack stamens.

4/24/16 Week 4; Monday Announcements: First lecture exam on Friday; Review session Wednesday at 5:30 Lecture: Rosidae s.l., continued Aceraceae - Maple family (2 gen/113 spp) Aceraceae are included in Sapindaceae in textbook, so be sure to note the restricted circumscription that we use in this class. 1) woody trees or shrubs 2) leaves opposite Mnemonic for remembering opposite leaved woody plants A MAD Cap Horse --> Adoxaceae, Maple, Ash, Dogwood, Caprifoliaceae, Horse chestnut. - typically palmate venation; usually simple, sometimes palmately compound (pinnately compound in Sapindaceae s.s.) 3) Flowers: - 4-5 parted - nectary disk - formed in staminal whorls - flowers bisexual or unisexual, if the latter, then plants either mono- or dioecious, or androdioecious (some plants with perfect flowers, some plants with male flowers only; example Mountain maple – A. glabrum) - may be insect or wind pollinated - fruit of 2 fused carpels each with pronounced wing and dispersed by wind “samaroid schizocarp” Floral formula: * 4-5, 4-5, 4-10, 2, samaroid schizocarp [carpels fused] The family Aceraceae now is included in a larger family, Sapindaceae, which is a paraphyletic ancestral group. The Sapindaceae largely is tropical and has more variation in floral morphology. This expanded family also includes the Hippocastanaceae, the Horse Chestnut or Buckeye family. Aceraceae and Hippocastanaceae both are monophyletic, but by recognizing those families as distinct from the traditional Sapindaceae, the Sapindaceae may be paraphyletic. So, the solution adopted by the textbook is to include them all in one family, Sapindaceae. The name “Sapindaceae” is used for the larger group, because it was used as a family name before either of the others.

3. Plant Taxonomy: Biological Concept of Species. General Characters
3. Plant Taxonomy: Biological concept of species. General Characters, with Floral formula and floral diagram citing Examples and Economic importance of following: (classification as per B&H) Dicotyledonae : Polypetlae: Annonaceae, Brassicaceae, Meliaceae, Leguminosae, Myrtaceae. Gamopetalae : Rubiaceae, Asteraceae, Lamiaceae, Apetalae: Euphorbiaceae, and Monocotyledonae : Liliacaeae. Biological concept of species. A biological species is a group of individuals that can breed together. However, they cannot breed with other groups. In other words, the group is reproductively isolated from other groups. "The words 'reproductively isolated' are the key words of the biological species definition". Many systems of classification of angiosperms have been proposed by many taxonomists from time to time. It can be divided into three broad categories: i. Artificial Systems based on superficial features. ii. Natural systems based on form relationships. iii. Phylogenetic systems based on evolutionary and genetic relationships. Natural Systems: In these systems the organisms are classified on the basis of their natural affinities (i.e. the basic similarities in the morphology) rather than on a single character for determining the affinities. Bentham and Hooker’s Classification:The most important and the last of the natural systems of classification of seed plants was proposed by two British taxonomists George Bentham (1800-1884), a self trained botanist, and Joseph Dalton Hooker (1817-1911), the first director of the Royal Botanical Garden, Kew (England). They recorded precise description of most of the plants known at that time. Their monumental work which took about quarter of a century for completion was described in three volumes of Genera Plantarum, published in Latin during July 1862 and April 1883.

FLORAL BIOLOGY of SUNFLOWER INTRODUCTION to SUNFLOWER  Kingdom: Plantae  Order: Asterales  Family: Asteraceae  Genus: Helianthus
FLORAL BIOLOGY OF SUNFLOWER INTRODUCTION TO SUNFLOWER Kingdom: Plantae Order: Asterales Family: Asteraceae Genus: Helianthus Sunflowers are usually tall annuals, That are grow to a height of 50-4oocm The rough and hairy stem is branched in the upper part in wild plants but is usually unbranched in domesticated cultivars. The petiolate leaves are deneted and often sticky. The lower leaves are opposite often heart- shaped. The upper leaves are alternate and narrow. They bear one or several to many wide terminal capitula, with bright yellow ray florets at the outside and yellow or maroon disc florets inside. Helianthus is made of two words-Helios & anthos Helios – Sun Anthos - flower • Origin is Mexico • Basic chromosome no, X=17 H.annus: 2n=2x=34 • Important varieties are Modern, jawalamukhi, js-1, MSFH8,17 Inflorescence This family is characterized by the presence of head or capitulum type of inflorescence. The number of florets in a head is variable from a few to several hundreds. The heads are of two types, heterogamous and homogamous. There are two types of florets in heterogamous heads.The central florets are tubular, bisexual and also known as disc florets.The marginal florets are ligulate, pistillate and also known as ray florets. In homogamous heads, all the florets are tubular . Flower Flowers are very small in size hence referred to as florets, sessile, bracteolate and epigynous. The disc florets are generally complete,bisexual and actinomorphic. whereas the ray florets are incomplete, pistillate and zygomorphic Calyx calyx is reduced to numerous hairy appendages called pappus, arranged on top of the ovary.
