Order asparagales The asparagales is a widely distributed order of monocotyledenous flowering plants, including around 29 families and 26,000 species. The APG II system of 2003 recognises the family and places it in the order asparagales in the clade monocots. Ruscaceae is a family of flowering plants in the order asparagales.
Asparagales are the largest order of monocots (Chase et al., 1995, 2000, 2006) and, in APG III (2009), the number of families recognized has fallen from 26 (APG, 1998) to 14, still a large number, but one that is more manageable for teaching purposes. These also have at least some characters that can be used to recognize them (see below).
Global Biodiversity Information Facility. Free and Open Access to Biodiversity Data.Aspergillosis is an infection caused by Aspergillus, a common mold (a type of fungus) that lives indoors and outdoors. Most people breathe in Aspergillus spores every day without getting sick. However, people with weakened immune systems or lung diseases are at a higher risk of developing health problems due to Aspergillus.Asparagus, or garden asparagus, folk name sparrow grass, scientific name Asparagus officinalis, is a perennial flowering plant species in the genus Asparagus. Its young shoots are used as a spring vegetable. It was once classified in the lily family, like the related Allium species, onions and garlic.
For example, the review of plant root anatomy in the order Asparagales and other monocotyledons by Kauff et al. listed only 12 non-orchid genera with this feature. This botanical briefing has a three-fold aim. First, we want to correct the current and misleading view of the occurrence of the velamen among angiosperms. Second, by mapping the presence of the velamen on a phylogenetic tree we.Read More
Classification of Plant Kingdom.

MONOLOGUE FOR AN ONION: AN ANALYSIS Cutting an onion breaks cells in its skin causing a reaction that results to the formation of volatile sulfur compound which, when mixed with tears coating our eyes, becomes sulfuric acid. This triggers the tear ducts to produce more tears to alleviate the imbalance in acidity the irritant has caused; the longer the eyes are exposed to the acid the greater.Read More

Abstract A morphological cladistic analysis is presented of the lilioid order Asparagales, with emphasis on relationships within the “lower” asparagoids, in the context of recent new data on both floral and vegetative structures.Read More
Advances in angiosperm systematics: examples from the Liliales and Asparagales. J. Torrey Bot. Soc. 126:58-62. 1999.-This overview of recent phylogenetic studies in the petaloid monocots focuses on the Hemerocallidaceae and Melanthiaceae, both segregates of the traditional and polyphyletic Liliaceae s.l. Synapomorphies for Hemerocallidaceae and Melanthiaceae are summarized. Data support the.Read More
This current system of classification of plants is based on the evolutionary relationship amid other plants. Coniferophyta (Gymnosperms) It is a group of plants which is primarily evergreen and are native to the temperate zone. There are about 700 species discovered to date. They are vascular, non-flowering plants which produce seeds without the production of flower and fruits. Some common.Read More
Asparagales relationships are nearly congruent with previous combined gene analyses, which were reflected in the APG III classification. Parsimony and Bayesian analyses yield identical relationships except for some slight variation among the core asparagoid families, which nevertheless form a strongly supported group in both types of analyses. In core asparagoids, five major clades are.Read More
Asparagales is an order of plants in modern classification systems such as the Angiosperm Phylogeny Group (APG) and the Angiosperm Phylogeny Web. The order takes its name from the type family Asparagaceae and is placed in the monocots amongst the lilioid monocots. The order has only recently been recognized in classification systems. It was first put forward by Huber in 1977 and later taken up.Read More
