Usage notes

 * Many dictionaries mention feminine gender, while Stephanus Ximenez' dictionary mentions masculine gender and while Englishmen mention neuter gender.
 * The neuter gender could be a guess based on Greek . However, the Greek neuter form has a short e in the nominative singular ending and not a long e. Also the plural form rhomboides can be found which does not fit to a neuter noun, but to a masculine or feminine noun.
 * Masculine gender does fit with Latin, Greek and also German  and  which also were declined like Latin words.
