ARIZONA-SONORA DESERT MUSEUM PLANT CARE INFORMATION White Spurge or Liga Euphorbia xanti DESCRIPTION: White Spurge is an upright, clumping semi-succulent that can produce hundreds of 1/4" white flowers with maroon highlights through most of the year. The flowers attract hummingbirds, although it is not adapted to pollination by them. It grows up to 7' tall (usually shorter) and spreads slowly by suckers. White Spurge is native to central Baja California and coastal Sonora, near Guaymas. This clone has larger leaves and flowers, and is more floriferous than the wild type. It came to us from a yard in Curea, Sonora, where it was being grown ornamentally. RECOMMENDED USE: Grow in a container, or as an accent, along a border or in the background. CULTURE: o Hardiness: It may be damaged by hard freezes (below 27 F), but quickly recovers from underground stems. Sun tolerance: Best in full sun. Shade promotes floppy growth and reduces blooms. Watering and feeding: In the ground water every one to two weeks during hot weather. For pot culture, water more frequently. Fertilization is probably not necessary in the ground, but would help containerized plants. Soil requirements: Plant in any well-drained soil. For pot culture, use a fast draining potting mix. Pruning: Suckering can be a control problem, but can be greatly reduced by restricting water to the base of the plant, or ringing the plant with a root-barrier to a depth of 18". Note: This plant, as with many species in the family Euphorbiaceae, produces milky sap when damaged. Some persons show skin sensitivity the sap, so care should be made to wash it off. .

Plant Pest Risk Assessment for Oblong Spurge, Euphorbia Oblongata 2008 (Revised 2013)
Oregon Department of Agriculture Plant Pest Risk Assessment for Oblong Spurge, Euphorbia oblongata 2008 (Revised 2013) Names: Oblong spurge, Euphorbia oblongata, a.k.a. eggleaf spurge Family: Spurge, Euphorbiaceae Findings of This Review and Assessment: Euphorbia oblongata, has been determined to be a category “A” rated noxious weed as defined by the Oregon Department of Agriculture (ODA) Noxious Weed Policy and Classification System. This determination was based on a literature review and analysis using two ODA evaluation forms. Using the Noxious Qualitative Weed Risk Assessment v.3.8, oblong spurge scored 58 indicating a Risk Category of “A”; and a score of 18 with the Noxious Weed Rating System v.3.2, indicating an “A” rating. Oblong spurge scored a very high “A” ranking. Introduction: Oblong spurge is a weedy escaped ornamental species of Euphorbia known from only one site in Salem and one ornamental planting in Eugene, Oregon. Suspected to have been introduced from California in contaminated flax or machinery that was used at the State Penitentiary flax mill in the early part of the 1900’s, it has slowly expanded its territory on the penitentiary property. Growing up to 3’ tall, this species is capable of forming dense stands in more arid climates and could be expected to be a troublesome weed to control should it spread and establish in eastern Oregon. Oblong spurge has a great capacity to infest riparian areas in Washington and Oregon. It is well adapted to a wide range of range, shrub and pine forest environments. In California, it has been found associated with French broom, blackberry and in dry drainages along roadsides.

Author for correspondence: Paul E. Berry, [email protected] Abstract Euphorbia subg. Chamaesyce contains around 600 species and includes the largest New World radiation within the Old World-centered genus Euphorbia. It is one of the few plant lineages to include members with C3, C4 and CAM photosyn- thesis, showing multiple adaptations to warm and dry habitats. The subgenus includes North American-centered groups that were previously treated at various taxonomic ranks under the names of “Agaloma ”, “Poinsettia ”, and “Chamaesyce ”. Here we provide a well-resolved phylogeny of Euphorbia subg. Chamaesyce using nuclear ribosomal ITS and chloroplast ndhF sequences, with substantially increased taxon sampling compared to previous studies. Based on the phylogeny, we discuss the Old World origin of the subgenus, the evolution of cyathial morphology and growth forms, and then provide a formal sectional classification, with descriptions and species lists for each section or subsection we recognize.

Received April 30, 2019; Revised June 16, 2019; Accepted July 12, 2019 Abstract Euphorbia L. (Euphorbiaceae) is the largest genus of flowering plants in the flora of Egypt. The present paper deals with the study of leaf architecture including venation patterns, marginal configuration and leaf shape characters in the Euphorbia species in Egypt. A classical clustering analysis (UPGMA) and principle component analysis (PCA) by PAST 2.17c ٥7 architectural leaf characters to discriminate the investigated taxa. Plates of light softwere are conducted based on microscope for cleared leaf, marginal ultimate veins details as well as tooth shape for studied taxa were provided. Results from multivariate analysis are kept in line with the traditional taxonomic sections of the genus in Egypt. The obtained phenogram is slightly matched with the tradition and modern classification of genus Euphorbia. The arrangement and attachment of leaves, laminar size, apex and base leaf features, symmetry of base and medial of blade, primary vein framework, major secondary veins course, minor secondary veins, tertiary veins course and areolation development have been considered to be the most important distinguishable characters in Euphorbia. Leaf morphology and venation characters can be considered as good taxonomic indicators in segregating Euphorbia heterophylla in a distinct section (Poinsettia) within subgenus Chamaesyce, in addition they can discriminate the closely related species of Euphorbia as shown in the constructed key.

DCorresponding author. Email: [email protected] This paper is part of an ongoing series: ‘The Evolution of Plant Functions’. Abstract. Crassulacean acid metabolism (CAM) is a specialised mode of photosynthesis that improves atmospheric CO2 assimilation in water-limited terrestrial and epiphytic habitats and in CO2-limited aquatic environments. In contrast with C3 and C4 plants, CAM plants take up CO2 from the atmosphere partially or predominantly at night. CAM is taxonomically widespread among vascular plants andis present inmanysucculent species that occupy semiarid regions, as well as intropical epiphytes and in some aquatic macrophytes. This water-conserving photosynthetic pathway has evolved multiple times and is found in close to 6% of vascular plant species from at least 35 families. Although many aspects of CAM molecular biology, biochemistry and ecophysiology are well understood, relatively little is known about the evolutionary origins of CAM. This review focuses on ﬁve main topics: (1) the permutations and plasticity of CAM, (2) the requirements for CAM evolution, (3) the drivers of CAM evolution, (4) the prevalence and taxonomic distribution of CAM among vascular plants with emphasis on the Orchidaceae and (5) the molecular underpinnings of CAM evolution including circadian clock regulation of gene expression.

Comparative Anatomical Study on Leaves of Three Euphorbia L. Species Rodica Bercu & Dan Răzvan Popoviciu
© Landesmuseum für Kärnten; download www.landesmuseum.ktn.gv.at/wulfenia; www.zobodat.at Wulfenia 22 (2015): 271–276 Mitteilungen des Kärntner Botanikzentrums Klagenfurt Comparative anatomical study on leaves of three Euphorbia L. species Rodica Bercu & Dan Răzvan Popoviciu Summary: The paper presents a comparative study on the leaf structure of three species belonging to Euphorbiaceae: Euphorbia myrsinites, E. nicaeensis subsp. dobrogensis and E. seguieriana. Anatomically, the leaves of the three species are relatively similar in their basic structure. However, differences appear regarding epidermal cells and cuticular papillae, mesophyll, density of stomata and type of stomatal complex, laticifers and development of the vascular system. Keywords: comparative anatomy, laticifers, leaves, stomata, Euphorbia Euphorbiaceae is the sixth largest plant family comprising 322 genera and about 8910 species, most common in the humid tropical and subtropical regions of both hemispheres (Webster 1987). Many species are commonly known as spurges (Radcliffe-Smith 1987 ). Euphorbia myrsinites L., also known as myrtle spurge, creeping spurge or donkey tail, is a perennial, herbaceous plant with sprawling stems growing up to 20 – 40 cm. The leaves are spirally arranged, fleshy, pale, glaucous, blueish-green, 1–2 cm long. The flowers are inconspicuous, but surrounded by bright sulphurous-yellow bracts (tinged red). They are flowering in spring. In the Romanian flora,Euphorbia myrsinites is considered as an endangered species (Dihoru & Negrean 2009). Euphorbia nicaeensis subsp. dobrogensis (Prodán) Kuzmanov is a herbaceous perennial, pale green, with hairless stems growing up to 40 cm, densely-foliated and branched at the top. The leaves are spirally arranged, 30 – 60 mm long and 15 –20 mm wide, elliptical in shape, obtuse on top and shortly mucronated.
