The interesting Jris which forms the subject of our 
illustration was first discovered by Mr. W. A. Manda near 
_ Wilmington, in North Carolina, and flowered for the 
first time in cultivation in the Harvard Botanic Garden, 
when it was described by the late Mr. S. Watson. While 
botanically very closely allied to J. versicolor, Linn., the 
plant now described, /. caroliniana, 8. Wats. is horticul- 
turally very distinct, and the two are readily discriminated 
by the characters to which Dr. Stapf has called attention.
