176 Berry: Mesozoic FLORA OF ATLANTIC COASTAL PLAIN 
Leaves narrow, linear-lanceolate in outline, equally pointed at 
both ends, short petioled, 5-10 cm. in length and 8-13 mm. in 
maximum width. Margins entire. Midrib stout below, tapering 
above, often somewhat flexuous. Secondaries more or less remote, 
about ten alternate pairs, branching from the midrib at angles 
varying from thirty-five to forty-five degrees, camptodrome, of 
fine caliber, often obsolete. 
This species was described by Newberry from the Dakota 
sandstone. Lesquereux subsequently made it one of the varieties of 
his Salix proteaefolia, although it is obviously entitled to inde- 
pendent specific rank. It is of rare occurrence in the Raritan 
formation of New Jersey, and is preéminently a species which 
characterizes the Magothy formation from New Jersey to Mary- 
land, and homotaxial horizons to the southward. It is recorded 
in beds of Magothy age from Marthas Vineyard to the Potomac 
River. It occurs in the Black Creek beds of North and South 
Carolina, and in the Middendorf member in the latter state. 
In Georgia, while not especially abundant, characteristic leaves 
of this species are found from the base to the top of the lower 
Eutaw formation in the western part of the state. In Alabama it 
is very common at a relatively large number of localities from the 
base to the top of the Tuscaloosa formation. It appears to be a 
common form in the Bingen sand occurring in both the lower and 
upper members. 
OCCURRENCE: Big Railroad Cut, one mile southwest of Max- 
well Spur; Adams Kaolin cuts near Murfreesboro, Pike County; 
Mine Creek, three and one half miles north of Nashville, Howard 
County. 
SALIx LESQUEREUXII Berry 
Salix proteaefolia Lesquereux, Cret. Fl. 60. pl. 5. f. 1-4. 1874. 
Salix Lesquereuxit Berry, Bull. Torrey Club 37: 21. Ig10. 
Leaves ovate-lanceolate in outline, somewhat more acu- 
minate above than below, variable in size, 6-12 cm. in length 
and I.1I—2.2 cm. in greatest width, which is usually slightly below 
the middle. Petiole stout, much larger than in Salix flexuosa, 
ranging up to I.2 cm. in length. Midrib stout below, tapering 
above. Secondaries numerous, sometimes as many as twenty 
pairs; they branch from the midrib at angles of about forty-five 
degrees and are parallel and camptodrome.
