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. -

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. ISSN 2153 733X STUDIES OF NEOTROPICAL COMPOSITAE–V. MUNNOZIA ORTIZIAE (LIABEAE), A NEW SPECIES FROM THE ANDES OF PASCO, PERU JOHN F. PRUSKI Missouri Botanical Garden P.O. 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.

This article is published with open access at Springerlink.com Abstract The biodiversity hotspot of the Equatorial Pacific region in western Ecuador and northwestern Peru comprises the most extensive seasonally dry forest formations west of the Andes. Based on a recently assembled checklist of the woody plants occurring in this region, we analysed their geographical and altitudinal distribution patterns. The montane seasonally dry forest region (at an altitude between 1,000 and 1,100 m, and the smallest in terms of area) was outstanding in terms of total species richness and number of endemics. The extensive seasonally dry forest formations in the Ecuadorean and Peruvian lowlands and hills (i.e., forests below 500 m altitude) were comparatively much more species poor. It is remarkable though, that there were so many fewer collections in the Peruvian departments and Ecuadorean provinces with substantial mountainous areas, such as Ca- jamarca and Loja, respectively, indicating that these places have a potentially higher number of species. We estimate that some form of protected area (at country, state or private level) is currently conserving only 5% of the approximately 55,000 km2 of remaining SDF in the region, and many of these areas protect vegetation at altitudes below 500 m altitude. -

APPENDIX D.2 Plant Survey Memorandum Athos Memo Report To: Aspen Environmental Group From: Lehong Chow, Ironwood Consulting, Inc. Date: April 3, 2019 Re: Athos Supplemental Spring 2019 Botanical Surveys This memo report presents the methods and results for supplemental botanical surveys conducted for the Athos Solar Energy Project in March 2019 and supplements the Biological Resources Technical Report (BRTR; Ironwood 2019) which reported on field surveys conducted in 2018. BACKGROUND Botanical surveys were previously conducted in the spring and fall of 2018 for the entirety of the project site for the Athos Solar Energy Project (Athos). However, due to insufficient rain, many plant species did not germinate for proper identification during 2018 spring surveys. Fall surveys in 2018 were conducted only on a reconnaissance-level due to low levels of rain. Regional winter rainfall from the two nearest weather stations showed rainfall averaging at 0.1 inches during botanical surveys conducted in 2018 (Ironwood, 2019). In addition, gen-tie alignments have changed slightly and alternatives, access roads and spur roads have been added. PURPOSE The purpose of this survey was to survey all new additions and re-survey areas of interest including public lands (limited to portions of the gen-tie segments), parcels supporting native vegetation and habitat, and windblown sandy areas where sensitive plant species may occur. The private land parcels in current or former agricultural use were not surveyed (parcel groups A, B, C, E, and part of G). METHODS Survey Areas: The area surveyed for biological resources included the entirety of gen-tie routes (including alternates), spur roads, access roads on public land, parcels supporting native vegetation (parcel groups D and F), and areas covered by windblown sand where sensitive species may occur (portion of parcel group G). -

Leaves 1¼ - 4 inches (3 - 10 cm) long, less than ¼ inch (1.5 - 5 mm) wide, flat, leaf bases overlapping and forming a fan. Flower stalk 1½ - 8 inches (4 - 25 cm) tall, ribbed, with a leaf-like sheath, as long as or slightly shorter than most of the leaves, enclosing the base of the stalk. Cone-like flower spike - inch (3 - 8 mm) long, oval, solitary at the top of the flower stalk, composed of many tan, papery, rounded, overlapping bracts, each bract with a small green patch; spikes usually produce only 1 flower per day. Flower with 3 yellow petals, rising from under a bract, opening in the morning and withering around noon; sepals are hidden under the bracts. Similar Species: Yellow-eyed grasses are very similar; this species is distinguished by the reddish-brown patch at the base of the plant and by the sheath of the flower stalk which is about the same length as the leaves. Related Rare Species: Harper’s yellow-eyed grass (Xyris scabrifolia, Special Concern) has a fleshy, pink-purple base; a twisted flower stalk with a sheath shorter than the leaves; and rounded petals. Its leaves are covered with tiny bumps which give them a rough texture and a glazed look. -
