152 Nymphaeaceae Cabomba 



2509. CABOMBA Aublel 



1. Cabomba caroliniana Gray. Fan WORT. This species was reported 

 by Schneck in 1876 as common in the deeper ponds of the Lower Wabash 

 Valley. Ridgway (Amer. Nat. 6: 726. 1872) tells of a journey which he 

 and Dr. J. Schneck made to Foote's Pond in Gibson County in September, 

 1871. He says: "Little, yellow, star-like flowers resting on the surface of 

 the water, with their cypress-like leaves submerged, were found to be the 

 Cabomba caroliniana." While there is no specimen, I believe we can as- 

 sume the determination to be correct because there is no other aquatic in 

 flower at that time of the year with which it could be confused. The species 

 is, no doubt, extinct in Indiana. I have visited Foote's Pond several times 

 and I have never seen it and I revisited it during the drought of 1930 and 

 1931 when it was dry for two years. I visited other deep ponds in the 

 Lower Wabash Valley at the same time and they were also dry. The 

 drought probably killed many other species there.

2510. BRASENIA Schreb. 



1. Brasenia Schreberi Gmel. Watershield. Map 929. Frequent, usu- 

 ally in 3-5 feet of water, on the borders of lakes and in a few dredged 

 ditches in the lake area, very local south of this area. Reported in the 

 southern part of the state by Banta from a pond in Jefferson County and 

 by Clapp and Schneck, who say it was rare. 



N. S. to Man., southw. to Fla. and Tex. ; also found in Cuba, Mex., Asia, 

 Africa, and Australia. 



2513. NYMPHAEA [Tourn.] L. Waterlily 



[Conard. The Waterlilies. 1-279. 30 pi., 81 fig. Carnegie Inst. Wash. 

 1905.] 



Rootstocks bearing numerous, globular tubers; tubers easily detaching when mature; 

 leaves green to purplish beneath, the veins usually more numerous and closer than 

 in the next species; stripes on petioles conspicuous or lacking; sepals green; 

 flowers mostly 10-23 cm in diameter, opening from 8 a. m. to 1 (2 or 3) p. m., 

 scentless or nearly so; petals obovate to almost spatulate, generally rounded at the 

 apex; filaments broader than the anthers; seed 2.8-4.4 mm long. . . .1. N. tuberosa. 



Rootstocks with few branches; branches not constricted at the base and persistent; 

 leaves deep red to green, tinged with red beneath; stripes on petioles lacking; 

 sepals often purplish outside; flowers mostly 7-12 cm in diameter, fragrant, open- 

 ing from 6 a. m. to 12 m.; petals elliptic; inner filaments narrower than the 



anthers; seed 1.6-2.3 mm long. (See excluded species no. 228, p. 1046.) 



N. odorata. 



1. Nymphaea tuberosa Paine. (Castalia tuberosa (Paine) Greene.) 

 Magnolia Waterlily. Map 930. This species is frequent to common in 

 the lakes and sloughs of the lake area and very local south of it because 

 its habitat is lacking. 



This species has generally been confused with Nymphaea odomta.
