BERBERIDA CE^. 



Caui.Ophyllum thalictroidics (L.) Michx. ¥\.—Lronti<-r thalio- 

 troides, L. Spec. 



Rich woods; infrequent. 



It has been suggested that Z^ow/o/f/n/ow ///«//<://-oJc/<'.s, Hill, Syst. Veg. xvi. 

 p. 26, be taken up, but 1 have not been able to satisfy myself that this should be done. 

 The above work gives under the genus Leontopclalon the following species : i, Le- 

 ontice crysogonttm \ 2. Leontice Leontopelaltim; 3. Leotttopelalon ihalictroides; 4. 

 Leontice Leoniopetaloides. These are the four species that are included by Linnaus 

 in his genus Leontice. 



Podophyllum peltatuim, L. Spec. 

 Rich woods ; frequent.

Brasenia nymphoides, (Thuub.) Baill. Hist. PL iii. p. 82, 1872.

 Ponds; rare. 



Along railroad a few miles northwest of Ames.

 phaa tuberosa, Paine, Cat. PI. Oneida Co. 1S65. — Nyiiip/icsa re?iifor-

 Ponds; becoming rare. 



In the immediate vicinity of the College there is no suitable habitat, but it occurs 

 frequently in the prairie ponds of the Big prairie and elsewhere. 



If Nyniphaa tuherosa, Paine, and N. renij'ormis are the same, as indicated in 

 Gray's Manual, 6th ed., our plant becomes Caaiali'a rtniformis (DC.) ; but there 

 seems to be much doubt as to tlie identity of DeCandolle's plant.

 L. Spec. 



Rich woods ; abundant. 

 The original spelling of the genus has been retained, since the evidence seems to 

 show that Borckhausen intended the word to be Diclytra. If the error be purely typo, 

 graphical it should be corrected. I have not access to Borckhausen's paper (Romer, 

 Archiv. f. d. Hot. i. 3, p. 46), but Bernhardi quotes from this paper (Linnxa xii. p. 

 66S, 1S3S), "Diclytra nenne ich (Borckhausen) sie (die Gattung) von fj,- zwei, 

 und K/.VTijni' !^porn, weil sich die Blume so deutlich durch ihre zwei Sporne 

 auszeichnet." 



Prof. Trelease suggests that the error may have arisen in a transfer of kenlton 

 from the original script into the Greek letters. The e. being made too high, be- 

 came an /, and then the « was read as !«, making klutron,
