For example, the "flower" of the well known Anthurium spp. is a typical spadix with a large colorful spathe. [ 1 ] In this type of inflorescence , the peduncle is thick, long and fleshy, having small sessile unisexual flowers covered with one or more large green or colourful bracts (spathe).
The Araceae are a family of monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe (or leaf-like bract). Also known as the arum family, members are often colloquially known as aroids.
The inflorescence's deep red color and texture contribute to the illusion that the spathe is a piece of meat. During bloom, the tip of the spadix is roughly human body temperature, which helps the perfume volatilize. The heated spadix creates a micro-convection in the cool ambient air, enhancing the transport of the scent.
A 40-year experiment conducted by the U.S. Public Health Service withheld standard medical advice and treatment from a poor minority population with an easily treatable disease. The experiment targeted black male farmers who were told they needed to be treated for 'bad blood', [ 27 ] but who were, in fact, syphilitic.
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's stem that is composed of a main branch or a system of branches. [1] An inflorescence is categorized on the basis of the arrangement of flowers on a main axis and by the timing of its flowering (determinate and indeterminate). [2]
The independent misconduct of two chemists at the William A. Hinton State Laboratory Institute in Massachusetts caused the drug lab to be shut down and tens of thousands of criminal convictions for drug possession to be overturned. Annie Dookhan admitted to faking test results and adulterating samples to make them consistent with her desired ...
The inflorescence is a spadix or spike surrounded by one or more bracts or spathes that become woody at maturity. The flowers are generally small and white, radially symmetric, and can be either uni- or bisexual. The sepals and petals usually number three each and may be distinct or joined at the base.
The leaves of A. maculatum appear in the spring (April–May in the northern hemisphere, October–November in the southern hemisphere) and are 7 to 20 cm long. [5] These are followed by the flowers borne on a poker-shaped inflorescence called a spadix, which is partially enclosed in a pale green spathe or leaf-like hood.
