It has been called Cerise Guigne since Duhamel described it in 1768, and may be the variety known long ago by the Romans as Cecilienne. There is no record to show that Cerise Guigne was ever brought to America. Tree large, vigorous, productive; fruit of medium size, roundish-cordate, flattened at the base; suture distinct; stem of medium thickness and length; skin thin; color clear red becoming reddish-brown; flesh clear red, with abundant, colored juice, tender, slightly stringy, sweet, sprightly, agreeable; quality good; ripens early. =Cerise de Mai Double.= Species? =1.= Knoop _Fructologie_ =2=:36, 40. 1771.
