According to Turco's "Book of Forms", the Decastich is any whole poem of ten lines.
There is no reference to meter or rhyme pattern and perhaps it for this reason, (lack of regulation) as to why it has been the subject of so much experimentation of poetic ideas lately.

Whilst researching this form under "ten line poetry forms" quite a lot of information emerged including two alternative names used for the Decastich, the Sonnetina and the Tritina. It was also found that the Australian poet, Alex Skovron had published a book titled "Infinite City" consisting of 100 ten line poems in which he called the form Sonnetina.
Later it was discovered that several other poets had also had the idea of a mini-sonnet and were using already established forms ie. couplets, quatrains, quintains, and sestets of various types to construct poems they called Sonnetina. Quite logically it was assumed, if forms are used similar to those of sonnet forms, then why should they not also be labeled as miniature sonnets or Sonnetina.

As stated previously ten-line poetry is not new and conventional library, as well as internet research finds ten line poetry forms fall into three general groups, free verse, (Decastich), miniature sonnets, (Sonnetina), and Tritina.
