Ceratophy Hum demersum L. 



Conard wrote me in 1933 that the latter species belongs to the Coastal 

 Plain and in the interior it does not occur as far south as Indiana. 



On August 12, 1930, I found a rose colored form in the west side of 

 Cheesborough Lake, Steuben County.

Leaves less than twice as long as wide; sinus a half to a fourth as long as the blade. 



Petioles terete; leaf blades not floating, erect or spreading; basal sinus open, widest 



at the base of the lobes; sepals, petals, and fruit generally greenish yellow or 



yellow but with no tinge of red or only the crown reddish 1. N. advena. 



Petioles conspicuously flattened; leaf blades floating; basal sinus narrow and usually 

 nearly closed ; sepals generally tinged with red inside at the base ; petals usually 

 red about half their length; fruit reddish at the base up to a half or three 



fourths its length 2. N. variegata. 



Leaves more than twice as long as wide; sinus less than a fourth the length of the 

 blade. (See excluded species no. 229, p. 1047.) N. sagittifolia. 



1. Nuphar advena Ait. (Nymphaea advena Ait.) Yellow Spatter- 

 dock. Map 931. In shallow, running or stagnant water in lakes, streams, 

 sloughs, and ponds throughout the state. Frequent to common in the lake 

 area, and infrequent south of it. 



N. Y. to Wis., southw. to N. C. and Tex. 



2. Nuphar variegata Engelm. (Nymphaea advena var. variegata 

 (Engelm.) Fern.) Variegated Spatterdock. Map 932. Probably limited 

 to the lakes of northern Indiana. I have no notes on its frequency or its 

 associates. I have seen it in three lakes in Noble County. It is certain 

 that it is much rarer than the preceding species.
