  • Class Monocotyledonae
    ACORUS/ACORACEAE 1077 CLASS MONOCOTYLEDONAE Plants usually herbaceous—in other words, lacking regular secondary thickening (except Palmaceae, Smilacaceae, most Agavaceae, and a few Poaceae); seedlings usually with 1 seed leaf or cotyledon; stems or branches elongating by apical growth and also by growth of basal por- tion of internodes; leaves when present alternate, whorled, basal, or rarely opposite, elongating by basal growth (readily seen on spring-flowering bulbs whose leaf-tips have been frozen back); leaf blades usually with parallel or concentrically curved veins, these unbranched or with inconspicuous, short, transverse connectives (leaves net-veined or with prominent midrib and spreading side-veins parallel with each other in Alismataceae, Araceae, Smilacaceae, Marantaceae, and some Orchidaceae); perianth with dissimilar inner and outer whorls (petals and sepals), or all parts about alike (tepals), the parianth parts separate or united, commonly in 3s, less often in 2s, rarely in 5s, or perianth of scales or bristles, or entirely absent. AWorldwide, the Monocotyledonae is a group composed of ca. 55,800 species in 2,652 genera arranged in 84 families (Mabberley 1997); 25 of these families occur in nc TX. The monocots appear to be a well-supported monophyletic group derived from within the monosulcate Magnoliidae group of dicots (Chase et al. 1993; Duvall et al. 1993; Qiu et al. 1993). From the cla- distic standpoint, the dicots are therefore paraphyletic and thus inappropriate for formal recog- nition (see explantion and Fig. 41 in Apendix 6). Within the monocots, Acorus appears to be the sister group to all other monocots, with the Alismataceae (and Potamogeton) being the next most basal group (Duvall et al.

  • From Megasporogenesis to Early Embryo Development Alejandra G
    González‑Gutiérrez and Rodríguez‑Garay SpringerPlus (2016) 5:1804 DOI 10.1186/s40064-016-3528-z RESEARCH Open Access Embryogenesis in Polianthes tuberosa L var. Simple: from megasporogenesis to early embryo development Alejandra G. González‑Gutiérrez and Benjamín Rodríguez‑Garay* Abstract The genus Polianthes belongs to the subfamily Agavoideae of the Asparagaceae family formerly known as Agavaceae. The genus is endemic to México and comprises about 15 species, among them is Polianthes tuberosa L. The aim of this work was to study and characterize the embryo sac and early embryo development of this species in order to gener‑ ate basic knowledge for its use in taxonomy, in vitro fertilization and production of haploid plants and to complement studies already performed in other genera and species belonging to the Agavoideae sub-family. It was found that the normal development of the P. tuberosa var. Simple embryo sac follows a monosporic pattern of the Polygonum type and starts its development from the chalazal megaspore. At maturity, the embryo sac is of a pyriform shape with a chalazal haustorial tube where the antipodals are located, just below the hypostase, which connects the embryo sac with the nucellar tissue of the ovule. The central cell nucleus shows a high polarity, being located at the chalazal extreme of the embryo sac. The position of cells inside the P. tuberosa embryo sac may be useful for in depth studies about the double fertilization. Furthermore, it was possible to make a chronological description of the events that happen from fertilization and early embryo development to the initial development of the endosperm which was classified as of the helobial type.

  • Yucca from Wikipedia, the Free Encyclopedia
    Yucca From Wikipedia, the free encyclopedia Yucca is a genus of perennial shrubs and trees in the family Asparagaceae, subfamily Agavoideae.[2] Its 40-50 species are notable for Yucca their rosettes of evergreen, tough, sword-shaped leaves and large terminal panicles of white or whitish flowers. They are native to the hot and dry (arid) parts of North America, Central America, South America, and the Caribbean. Early reports of the species were confused with the cassava (Manihot esculenta).[3] Consequently, Linnaeus mistakenly derived the generic name from the Carib word for the latter, yuca (spelt with a single "c").[4] It is also colloquially known in the Midwest United States as "ghosts in the graveyard", as it is commonly found growing in rural graveyards and when in bloom the flowers appear as floating apparitions.

The natural distribution range of the genus Yucca (49 species and 24 subspecies) covers a vast area of North and Central America. From Baja Species California in the west, northwards into the southwestern United States, through the drier central states as far north as Alberta in Canada (Yucca See text. glauca ssp. albertana), and moving east along the Gulf of Mexico, and then north again, through the Atlantic coastal and inland neighbouring Synonyms states. To the south, the genus is represented throughout Mexico and extends into Guatemala (Yucca guatemalensis).

Ramiro Ríos Gómez, M. en C. María Magdalena Ayala H., M. en C. Héctor Serrano Casas Colaboradores: M. en C. Miguel Rivera Lugo, QFI. Ma. Luz López Martínez Introducción Yucca es un género americano conformado por 35 a 49 especies distribuidas desde el suroeste de Canadá hasta Guatemala (Matuda y Piña, 1980). La mayor riqueza de especies se ubica en las zonas áridas y semiáridas del sur de Estados Unidos y norte de México (Clary, 1997). Las yucas habitan preferentemente en el matorral xerófilo, no obstante, también se localizan en los bosques tropicales o templados, y en raras ocasiones se observan en las dunas. En México se encuentra más del 60% de las especies , y 50% de ellas son endémicas (García-Mend., 2011). Sus flores, frutos y el pedúnculo floral son un alimento común en varias regiones de la República, las hojas se usan para techar casas y con sus fibras son elaborados diversos utensilios. Las especies de este género no han sido bien delimitadas, diversos autores en función de criterios diferentes utilizados han propuesto distintas clasificaciones. Se han realizado estudios anatómicos, citogenéticos y filogenéticos de algunas especies. En la actualidad no existe un análisis filogenético de Yucca que incluya a todos los taxa, y que combine caracteres moleculares, citométricos, morfológicos, anatómicos y biogeográficos, que permitan resolver la problemática taxonómica de este género complejo.

HOLMES Department of Biology Baylor University Waco, Texas 76798-7388 [email protected] ABSTRACT An inventory of the vascular flora of McLennan County, Texas, located in northern east- central portion of the state, has resulted in the documentation of 1145 species from 127 families. McLennan County contains three physiographic areas: Blackland Prairie, Grand Prairie (which includes the Lampasas Cut Plain/Washita Uplands), and the East Cross Timbers. The plant list includes 32 species that are endemic to Texas and 388 species that are county records. The most noteworthy species is Cheilanthes lanosa, the only Texas record for the species. KEY WORDS : Texas, McLennan County, floristics Published works discussing the flora of McLennan County date back to 1892 with an article (“popular account”) by E.N. Plank in Garden and Forest . The sole effort to describe the flora of the county was by Lula Pace, former Professor of Botany at Baylor University, who published a list of the flora of the county in the University of Texas Bulletin in 1923 (Adkins 1923).

SpringerPlus 2014, 3:575 http://www.springerplus.com/content/3/1/575 a SpringerOpen Journal RESEARCH Open Access Embryo sac formation and early embryo development in Agave tequilana (Asparagaceae) Alejandra G González-Gutiérrez, Antonia Gutiérrez-Mora and Benjamín Rodríguez-Garay* Abstract Agave tequilana is an angiosperm species that belongs to the family Asparagaceae (formerly Agavaceae). Even though there is information regarding to some aspects related to the megagametogenesis of A. tequilana, this is the first report describing the complete process of megasporogenesis, megagametogenesis, the early embryo and endosperm development process in detail. The objective of this work was to study and characterize all the above processes and the distinctive morphological changes of the micropylar and chalazal extremes after fertilization in this species. The agave plant material for the present study was collected from commercial plantations in the state of Jalisco, Mexico. Ovules and immature seeds, previously fixed in FAA and kept in ethanol 70%, were stained based on a tissue clarification technique by using a Mayer’s-Hematoxylin solution. The tissue clarification technique was successfully used for the characterization of the megasporogenesis, megagametogenesis, mature embryo sac formation, the early embryo and endosperm development processes by studying intact cells. The embryo sac of A. tequilana was confirmed to be of the monosporic Polygonum-type and an helobial endosperm formation. Also, the time-lapse of the developmental processes studied was recorded.
