Arboretum succeeded in germinating several seed. The New York 

 Gardens succeeded in getting 5 seedlings. The Missouri Gardens failed 

 to get any to germinate. About a gallon of seeds was planted in the 

 Clark County State forest nursery and all failed. 



2. Quercus bicolor Willdenow. SWAMP WHITE OAK. Plate 41. 

 Large trees; leaves on petioles 5-20 mm. long, 8-18 cm. long, obovate, 

 wedge-shaped or narrowly rounded at base, rounded or pointed at the 

 apex, margins coarsely divided with rounded or blunt teeth or some- 

 what pinnatifid, primary venation beneath somewhat regular, but usual- 

 ly some of the veins end in a sinus of the margin, both surfaces hairy at 

 first, becoming smooth above and remaining velvety pubescent beneath; 

 the upper surface of the leaf a bronze or dark green and the under sur- 

 face grayish due to the dense tomentum, which in some instances be- 

 comes sparse and short, in which case the under surface is a light green; 

 acorns usually in pairs on stalks 2-7 cm. long; nuts ovoid, 2-2.5 cm. long, 

 enclosed for ^-^ their length in the cup; scales of cup acute to 

 very long acuminate, scurvy pubescent and frequently tuberculate; 

 kernel sweetish. 



Distribution. Maine, southern Ontario, southern Minnesota south 

 to Georgia and Arkansas. Found in all parts of Indiana. It is always 

 found in wet places. In most of its range it is associated with the bur 

 oak from which it is not commonly separated. In the northern counties 

 it is usually associated with pin and bur oak, and white elm; in the flats 

 of the southeastern part of the State it is usually associated with cow 

 oak and sweet gum, while in the southwestern counties it is found most 

 commonly with Spanish and pin oak. 



Remarks. Commercially the wood is not distinguished from white 

 oak, and the cut is sold for that species. 



3. Quercus Muhlenbergii Engelmann. CHINQUAPIN OAK. SWEET 

 OAK. YELLOW OAK. CHESTNUT OAK. Plate 42. Large trees; leaves 

 on petioles 1-3 cm. long, blades very variable in size, shape and leaf 

 margins, generally 10-20 cm. long, oblong-lanceolate to broadly obovate, 

 narrowed or rounded and more or less unequal at the base, taper-pointed 

 at the apex, the apex always forming an acute angle, margins coarsely 

 and rather regularly toothed, primary veins beneath regular and 

 straight, and end in a prominent gland in the point of the teeth, teeth 

 more or less incurved, leaves smooth and dark green above, and grayish 

 pubescent beneath; acorns generally sessile, but often on short stalks 

 up to 1 cm. long; nut ovoid to oblong ovoid, 10-18 mm. long, enclosed 

 for %-y<i its length in a very thin cup; scales of cup ovate, blunt- 

 pointed or merely acute, sometimes tuberculate near the base of the 

 cup, grayish pubescent without; kernel sweet, and the most edible of 

 all of our oaks.
