CONIFERALES (PINACEAE) 



247 



bore axillary ovuliferous scales as in the normal cone. He concluded 

 that stamens are to be homologized with the bracts of the ovuliferous 

 cone, and that the 

 ovuliferous scales 

 are axes of the next 

 higher order. Simi- 

 lar cones have been 

 reported by Shavv^ 

 (42) from Sequoia, 

 and by Goebel 

 (58) from Pinus. 

 For some, such illus- 

 trations settle the 

 sporophyll charac- 

 ter of the bract in 

 both cones, and to 

 them the bract of 

 the ovulate cone is 

 a carpel. 



In i860, also, 

 Caspary (8) con- 

 firmed Braun's 

 conclusion, citing 

 specimens in which 

 branches occurred 

 in the axils of the 

 bracts, and bore 

 the two halves of 

 the ovuliferous scale 

 as lateral append- 

 ages. 



In 1864 Parla- 

 TORE recorded (12) 



a cone of Pinus Pinaster (P- Lemoniana) in which an ordinary dwarf 

 shoot with its two needle leaves sprang from the axil of every 

 alternate bract, replacing the ovuliferous scale. His conclusions 

 naturally accorded with those of Braun.
