calathid, calathids, calathidia, calthidium, calathide?
The article contains this sentence: "Pseudanthia are characteristic of the sunflower family (Asteraceae), where they are called calathidia, calathids or capitula."
The various forms of calathid are very rarely used terms. The following on-line botanical glossaries do not mention any form of the word:
In addition, the book, Plant Identification Terminology (2001), by James G. Harris and Melinda Woof Harris does not have a definition for the term.
A google scholar search for calathid returned very few papers that used the term in a botanical sense. The most significant results (both papers might require registration):
http://www.springerlink.com/content/n0r4w6l641l38383/fulltext.pdf - A 1944 paper discussing the formal description of flowers. According to the paper various forms of the terms have been around for awhile. The paper reports that calathide was introduced in 1815, however it does not specifically refer to calathid as being a valid term.
http://www.academicjournals.org/jmpr/PDF/pdf2012/30Jan/Bibalani%20and%20Taheri.pdf - Investigation on flowering period of Asteraceae members in the Shanjan region Shabestar district, Northwest Iran (usage for honeybees) - This paper contains the same sentence that appears in the Asteraceae Wikipedia article: "The most evident characteristic of Asteraceae is perhaps their inflorescence: a specialised capitulum, technically called a calathid or calathidium, but generally referred to as flower head or, alternatively, simply capitulum."
The source of this sentence according to the Wikipedia Asteraceae article is the 1966 book, "A dictionary of botany, including terms used in bio-chemistry, soil science, and statistics".
In summary there are not any recent botanical glossaries that define the term and there are almost no links in Google Scholar for any use of the term while Google Scholar links to numerous papers that use capitulum, flower head and Pseudanthia. Based on the above it is my intention to delete the terms calathid, calathids and calathidia from the article unless there is discussion to the contrary.--Davefoc (talk) 08:06, 26 February 2012 (UTC)
