HALORAGIACEiE. 155 



HALORAGIACE^. 



MYEIOPHYLLUM, L. 



298. M. spicatum, L. Sjnked Water Milfoil.. 



Native ; in ponds, rivers, and slow streams. Common. July. 

 0. I. In the stream from the Tidy supplying Heskyn ^lill. 

 D. III. In the leats at Pennycross. 



IV. Pond at Radford ; ilfr. Ralfs. In the Plym, below Riverford. 

 Meavy Valley. 

 V. In the Yealm, near Cornwood. 



VI. In Shilstone Brook, immediately above Gutsford Bridge. In a 

 large pond on the right bank of the Erme, at Pamtiete ; abun- 

 dant and fruiting plentifully, August, 1873. 

 When in streams rarely, perhaps never, producing flowers. This may 

 be owing to their generally rapid current here. 



CALLITRICHE, L. 



297. C. verna, L. Vernal Water Starwort. 



Native ; m a dram in a marsh. Very rare ? 

 D. VI. Drain in the marsh between the lodge nearest Ermington on the 

 Flete grounds and Sequers Bridge. 

 I sent the plant from the above station to Dr. Boswell, who said he 

 thought it must be called vernalis {verna) from the fruit, but added that 

 he had never before seen this with spathulate leaves. Mr. Keys says of 

 verna, "about Plymouth and generally througliout the county" (Devon), 

 and as to Cornwall, adds " common." I question these statements. 



298. C. obtusangula, Le Gal. Ohtuse-fruited Water Starwort. 



Native ; in marsh drains. Very rare. 

 D. IV. In the water of a drain in the marsh between the Plymouth and 

 Exeter Road and Saltram, at Marsh Mills, near Longbridge : 

 discovered in 1877. Drain in Chelson Meadow ; probably 

 ohtusangula, but fruit wanting for exammation, September, 

 1879. 



299. C. stagnalis, Scoi^., mclusive of h. platycarpa. Large-fruited 



Water Starwort. 

 Native ; in shallow pools, and on mud by ditches and springs. 

 Very common. April to October. Area general. 

 Extends over all the enclosed country, and occurs also in wet places on 

 some of the open commons.
