The cytogenetics of interspecific hybrids among the four cultivated cotton species were studied in this paper and results are as follows: The diploid interspecific hybrid (G. arboreum×G. herbacium) F〓 had a four-chromosome-ring at the meiotic metakinesis.

Those lines that I before have writ do lie, Even those that said I could not love you dearer, Yet then my judgment knew no reason why, My most full flame should afterwards burn clearer, But reckoning time, whose millioned accidents Creep in 'twixt vows, and change decrees of kings, Tan sacred beauty, blunt the sharp'st intents, Divert strong minds to the course of alt'ring things: Alas why fearing of time's tyranny, Might I not then say 'Now I love you best,' When I was certain o'er incertainty, Crowning the present, doubting of the rest?
