282 Lake Maxinkuckee, Physical and Biological Survey 



on Long Point, one on the north shore of the lake between the rail- 

 road bridge and depot, and several on the hill by Overmyer's field. 

 It was nearly in flower on the east side and leafing out well April 

 30, 1901. The wood, after drying out, is exceedingly hard. In 

 autumn the fruits, which are composed of hop-like clusters of whit- 

 ish or yellowish green little sacs, each containing a seed, are often 

 abundant enough to make a conspicuous object at some little dis- 

 tance. There are interesting points of resemblance between them 

 and the fruits of some of the sedges, although the structure is in 

 reality considerably different. 



In the summer of 1909 a remarkably peculiar little tree of this 

 species was found on Yellow River at Plymouth, Indiana. One 

 half of each leaf was wholly white while the other half was green 

 with white splotches and veins. The white portion of each leaf was 

 so placed that, if the half of the right of the midrib of the first leaf 

 were white, the left of the next would be white, the right of the 

 third, and so on. 



255. HAZEL-NUT 



CORYLUS AMERICANA Walt. 



Common in open woods and at the edges of forests on both sides 

 of the lake. Found south of the lake (Farrar's woods), southwest 

 of the lake (east of Lost Lake outlet), on Long Point, east of the 

 lake, and on the ice-ridge below Farrar's. Abundant along roads 

 a mile or two west of the lake. It does not seem usually to bear 

 abundantly near the lake, though in 1906 the crop along the roads 

 just mentioned was exceptionally heavy. Weevils occasionally in- 

 jure the nuts, and it is said that bluejays sometimes make raids on 

 patches and entirely strip them of fruit. September 18, 1900, fruit 

 was "found ripe in the clump east of Lost Lake outlet. April 5, 

 1901, some were fully in flower by the grist-mill and by Green's 

 orchard, in a gully north of the Gravelpit. This species has a long- 

 period of flowering; on April 7, on bushes in Farrar's woods some 

 of the catkins had blossomed and dried up, some were just in blos- 

 som, some were just half in bloom, the proximal half golden and 

 loose, the distal half still compact, and some catkins were still firm 

 and compact. By April 11, most were out of flower. By April 27, the 

 leaf buds showed green and three days later the bushes were pretty 

 well leaved out. Young seedling hazel plants usually have con- 

 spicuous brown blotches in the middle of the leaf, making them very 

 attractive, but these do not appear on later leaves.
