Also, the paper provides information about the hayfields floral richness, a great scientific value for Romania and Europe. The study of the flora was carried out in several stages: 2005-2008, 2013, 2017-2018. In the studied area, 397 taxa were identified, distributed in 82 families with therapeutic potential, represented by 164 medical taxa, 37 of them being in the European Pharmacopoeia 8.5. The study reveals that most plants contain: volatile oils (13.41%), tannins (12.19%), flavonoids (9.75%), mucilages (8.53%) etc. This plants can be used in the treatment of various human disorders: disorders of the digestive system, respiratory system, skin disorders, muscular and skeletal systems, genitourinary system, in gynaecological disorders, cardiovascular, and central nervous sistem disorders. In the study plants protected by law at European and national level were identified: Echium maculatum, Cephalaria radiata, Crambe tataria, Narcissus poeticus ssp. radiiflorus, Salvia nutans, Iris aphylla, Orchis morio, Orchis tridentata, Adonis vernalis, Dictamnus albus, Hammarbya paludosa etc. Keywords: Fărăgău, medicinal plants, human disease, Mureş County 1. -

Poisonous Hemlocks
POISONOUS HEMLOCKS THEIR IDENTIFICATION AND CONTROL J . M. Tucker • M. E. Fowle r • W. A. Harvey • L. J. Berry .. POISONOUS HEMLOCKS THEIR IDENTIFI CA TION AND CONTROL THE poisonous plants referred to in this publica tion as "hemlocks" are members of the carrot or parsley family, Umbelliferae, and should not be confused with true hemlocks, which are coniferous trees of the pine family, Pinaceae. Poisonous hem locks are of two genera: Conium (Poison Hemlock), and Cicuta {Water Hemlock). They have a general family resemblance to one another but are not closely related; their toxic properties and effects are different, they present different problems to the live stock industry, and they have different diagnostic features.

BERENBAUM Department of Entomology, University of Illinois at Urbana-Champaign, 320 Morrill Hall, 505 S Goodwin Ave., Urbana, IL 61801 Environ. Entomol. 35(3): 607Ð615 (2006) ABSTRACT Conium maculatum L. (Apiaceae), or poison hemlock, is an invasive plant native to Europe that has become extensively naturalized throughout North America. This species contains piperidine alkaloids, including coniine and ␥-coniceine, that are highly toxic to vertebrates. C. maculatum was relatively free from herbivores in North America until the accidental introduction 30 yr ago of its monophagous European associate Agonopterix alstroemeriana (Clerck) (Lepidoptera: Oecophoridae). At present, A. alstroemeriana is widespread across the United States, and in some areas, such as the Northwest, can inßict substantial damage on its host plant, leading to desiccation and death. A. alstroemeriana has been used in recent years for the biological control of C. maculatum, although its use has been limited by the availability of larvae, which are Þeld-collected from early to mid-spring, and by the lack of available information about its life history and feeding habits. Here we describe a laboratory-rearing protocol incorporating a simulated winter to induce diapause and a semideÞned artiÞcial diet that allows the production of multiple generations per year and enabled us to determine the number and duration of A. -

Poison Hemlock a 60 Year Old Female Ate “Wild Carrots” Pulled from the Ground Behind Her Home
August 2016 Poison Center Hotline: 1-800-222-1222 The Maryland Poison Center’s Monthly Update: News, Advances, Information Poison Hemlock A 60 year old female ate “wild carrots” pulled from the ground behind her home. One hour later, she began vomiting. She called 911 and the poison cen- ter complaining also of lightheadedness, dizziness and shortness of breath. EMS transported her and a sample of the plant to the emergency department (ED). In the ED, she was awake and alert, HR 120, BP 176/110, RR 22, O2 satu- Conium maculatum ration 98% on room air. All symptoms resolved within 24 hours of the inges- tion and she was discharged on day 2. The ED staff identified the plant as “poison hemlock” by means of an internet search. Poison hemlock (Conium maculatum) is an invasive herb in the carrot (Apiaceae) family. It can be found along roads, ditches, fences, streams, or anywhere with adequate moisture, throughout the U.S. Other common names for the plant are deadly hemlock, poison parsley, and winter fern. The poison hemlock plant grows to 4-10 feet tall and has a smooth, non-hairy, hollow stem with red-purple streaks. These blotches are called the “blood of Socrates” as poison hemlock was reportedly used to kill Socrates. The small white flowers grow in -4 6 inch wide “umbels” or clusters that resemble um- brellas. The leaves have a lacy, fern-like appearance.

Poison Hemlock (Conium Maculatum)
Weed Identification and Control Sheet: www.goodoak.com/weeds WI NR-40: Poison Hemlock (Conium maculatum) Prohibited DESCRIPTION: Poison hemlock was introduced to North America in the 1800s from Europe, western Asia, and North Africa as a garden plant for its attractive ferny foliage. This member of the carrot family is toxic to most animals and eating even a small fragment can kill a human. All parts of the plant are poisonous, but the root is especially toxic. This biennial or short-lived perennial prefers moist soils and full to partial sun. In such habitats it forms dense stands that out-compete natives for space and light. It spreads extensively by seed, producing more than 30,000 seeds per plant and remains viable in the soil for several years. These seeds are released from late summer into winter and are dispersed by water, wind, and attaching itself to fabric and fur. Since it is a new invader you should report any sightings of this plant to the DNR (see: http://dnr. wi.gov/topic/Invasives/report.html). IDENTIFICATION: In the first year poison hemlock produces large rosette leaves; the second year a tall stem emerges and the plant flowers. Poison hemlock grows 3 to 10 ft. tall with a ribbed hol- low stem with purple spots. This species has a umbel shape flower cluster with small white flowers that have petals and blooms June to July. Leaves are opposite and triangular in outline and have a fern like shape. Leaves when crushed release a foul odor. Poison hemlock can be confused with water hemlock, a rare native found only in good-quality wetlands, but the leaves can help distinguish these two species. -
Poison Hemlock G
Pasture Weed Fact Sheet W 325 Poison Hemlock G. Neil Rhodes, Jr., Professor and Extension Weed Management Specialist Trevor D. Israel, Extension Assistant Department of Plant Sciences Poison Hemlock Conium maculatum L. Classification and Description Poison hemlock, also called deadly hemlock, poison parsley, spotted hemlock, and California fern, is a highly poisonous bien- nial weed that is a member of the family Apiaceae, which is also referred to as the carrot family. It was originally introduced as a garden plant because of its attractive flowers. Other members of this family include wild carrot (Daucus carota L.), wild chervil (Anthriscus syvlestris (L.) Hoffm.), and a close relative to poison hemlock, water hemlock (Cicuta maculata L.). This native of Eurasia is found throughout Tennessee where it usually occurs in patches in cool-season grass pastures, roadsides, drainage ditches and stream banks. The cotyledons or seed leaves of seedlings are Fig. 1. Poison hemlock flowers in compound umbels. oblong-lanceolate, and the first true leaf is pinnately compound and glabrous. Flowers are small and white in large, compound umbels 1.5 to 2.4 inches wide (Fig. 1). The hollow stems of this plant are ridged, glabrous, and purple-spotted (Fig. 2). Leaves form a basal rosette; they are alternate upward, petioled, approxi- mately 8 to 16 inches long, broadly triangular-ovate, and com- pound. Leaflets are lanceolate to ovate-oblong, finely cut, less than 0.5 inch long. Crushed leaves have a mouse-like odor. Ma- ture plants can be 3 to 4 feet tall (Fig. 3) with fibrous roots branching from a turnip-like taproot (Fig.
