southern Michigan, south to Delaware and in the mountains to north- 

 eastern Tennessee." 



C. coccinea has the following record for the State: Floyd (Deam) ; 

 Noble (VanGorder) ; Steuben (Deam). 



The specimen taken was from a lone tree, one-fourth mile south of 

 Buffalo on a high, gravelly river-bank. Tree 20 feet high, 5 inches in 

 diameter. No. 343. September 1, 1915. Additional material is not to 

 be had before the completion of this thesis and so the exact determina- 

 tion must be deferred till some later date. (See p. 457 for other Haws, 

 also p. 449.) 



Thus the Tippecanoe River has some 28 species clinging closely to 

 its banks, besides claiming specimens of all other species in White 

 County, except possibly one or two species of willows, Quercus ellip- 

 soidalis and Malus ioensis. 



5. Report of a New Species and a New Variety for the State. 



Salix missouriensis Bebb. Missouri or Diamond Willow, Heart- 

 leaved Willow. 1895. 



S. cordata Muhl. 1803; S. angustata Pursh. 1814; S. cordata angus- 

 tata (Pursh) Anders. 1867; S. acutidens Rydb. 1901. 



The above are the synonyms given in Britton and Brown, 2nd Ed., 

 with S. cordata Muhl. preferred. 



Sargent, who determined my specimen, called it S. missouriensis. 



In Gray's Manual, 7th Ed., cordata and missouriensis are treated 

 as separate species, the last, however, with this note: "A poorly under- 

 stood tree, said to flower earlier than S. cordata; perhaps a variety 

 (var. vestita Anders.) of that species.'' 



In Hough's Handbook of the Trees of the Northern States and 

 Canada, the Missouri Willow is given as Salix missouriensis Muehl., 

 with the synonym of S. cordata var. vestita Sarg. 



In the face of all the above, hybridization is mentioned by each of 

 the contending authors. (See ranges given on map, p. 450.) 



This willow has hitherto been unreported for the State except that 

 S. cordata Muhl. and S. cordata angustata (Pursh) Anders, are reported 

 in Coulter's Catalogue, the former with the record: "In a few counties 

 in rather sparing numbers, growing in low, moist soils. More abundant 

 southward. Flowers in April and May. Putnam (MacDougal) ; Vigo
