Thus I have given here 10 sp. of Iris, either new or quite- 

 rare ; this account doubles our knowledge of this Genus, of 

 which we have now about 20 sp. I possess nearly all the 

 others Iris cristala, verna, virginica (these 3 often blended 

 like the 3 next) versicolor, prismatica, gracilis, hexagona r 

 missurica, sibirica, tenax figured by Hooker 3343 and Lind- 

 ley 1218. These two last are from Origon. I shall perhaps 

 resume a monograph of this pretty genus. 



APPENDIX. 



My Genus DIPLOSTELMA 316 which Nuttal had wrongly 

 reduced to Jictinocarpus in Collins herb, (there is no such 

 genus, he meant probably Aclinospermum of Elliot) has been 

 described by him under the name CHETANTHERA in his new 

 plants 78, without any reference to former name! whence it 

 escaped my notice ; but he has only one sp. C'h. asteroides (a 

 bad name) which is my Dipl. pumila, the rays are violet and 

 the blossoms are vernal. I have added 2 other sp. and my 

 name is the best, although NuttaPs dates of 1834, Chetanthe- 

 ra means bristly anthers, while this is not the case, he ought 

 to have named it Chelopappus, but as the pappus is double and 

 different mine is the best and must be retained.
