and oblong and attain a length of 5-10 mm. at the time of flowering. 

 They develop more slowly than the male. Each pistillate flower con- 

 sists of 2 carpels fused in their ovarian portion to form an ovate one- 

 chambered compound ovary, which is narrowed above into two elongated 

 spreading styles and stigmas. The pistillate flowers are arranged along 

 a rachis in a 2/5 spiral. Each is inserted in the axil of a deciduous bract 

 and accompanied by four deciduous bracteoles.

The catkins of this plant possess a peduncle and rachis more hairy 

 than those of M. cerifera. Furthermore, they have but one kind of 

 glandular hair, the golden-yellow balloon type. The male catkins 

 (Plate 84. Fig. 11) are 6-8 mm. long and about 5 mm. wide. The writer 

 has found the staminate flowers of the male catkins with anthers in the 

 tetrad state at Noroton, Connecticut, April 27, 1914. He has also ob- 

 served them with mature pollen and ready to dehisce at Wildwood, 

 N. J., May 13, 1914. In material collected at Clementon, N. J., April 

 23, 1915, the writer has observed tetrads and young pollen. Each 

 staminate flower consists of 4-8 stamens whose filaments are welded 

 together similarly to those of M. cerifera in half of their length, thus 

 forming a staminal column which is inserted in the axil of a bract. The 

 bract is thin hairy along the margin and yellow glandular hairy beneath. 

 Bracteoles are either present or absent. 



The female catkins (Plate 84. Fig. 10) are 8-10 mm. long and oblong 

 in shape. Each pistillate flower inserted thereon consists of 2 carpels 

 fused in their ovarian portion to form an ovate one chambered compound 

 ovary, which is extended above into 2 spreading styles and stigmas. 

 It is inserted in the axil of a greenish oval-lanceolate bract. The bract 

 is obtuse at its summit, slightly hairy along its margin, and conceals 

 two small deciduous bracteoles which are situated in its axil. 



Myrica Macfarlanei, Youngken 



The male and female catkins of the hybrid between M. cerifera and 

 M. Carolinensis resemble those of M. cerifera in possessing both orange- 

 red bowl-shaped and golden-yellow balloon-shaped glandular hairs 

 on both catkin axis and the bracts. Other characters are still under 

 investigation by the writer.

The male catkins of this plant are cylindrical (Plate 84. Fig. 9) 10-15 

 mm. long at the time of flowering. The staminate flowers each consist
