 The spelling and etymology of these terms is discussed, and the variation in usage by different 

 authors is noted. The first use of the terms was by J. EtOEPEBin Linnaea L. 433, and the ori- 

 ginal spelling was androcceum and gynoeceum. Later in many texts the spelling of the latter 

 term became gynoeceum. The author agrees with BOWEB in preferring the form given in 

 the title. He states that the Greek derivation does not signify the "female apartment" of 

 the house, but the female place or part of the flower and has no reference to "women." How- 

 ever, "To return to the -eum of P.oeper, may be satisfying to the more- pedantic; the atti- 

 tude of Bentham (who used -him) is good enough for any English botanist; but the use of 

 ae instead of oe, is not only distinctly wrong but extremely foolish."— K. M. Wiegand. 



2420. Church, Margaret B. The development and structure of the bulb in Cooperia 

 Drummondii. Bull. Torrey Bot, Club 46: 337-362 PL 14-16, fig. 1-9. 1919— The germina- 

 tion and development of the seedlings of Cooperia are described with special reference to the 

 formation of the bulb, which is set deep down into the ground by root-contraction. The ma- 

 ture bulb is described, as well as the formation of offsets, flower scapes and leaves. — P. A.

2421. Collins, G. N. Structure of the maize ear as indicated in Zea-Euchla>ena hybrids. 

 Jour. Agric. Res. 17: 127-135. PI. 16-18. 1919.— Hybrids of maize (Zea mays) and its near 

 relative, Euchlaena mexicana, offer a partial solution *>f the puzzling morphology of the pis- 

 tillate inflorescence of the former. These hybrid plants exhibit intermediate stages between 

 the simple spike of Euchlaena and the complex ear of Zea. In the parent forms each "meta- 

 mer" of inflorescence bears a morphological unit of spikelets (either staminate or pistillate; 

 either, two, one sessile and one pedicelled, or one, the second suppressed) which is designated 

 by a new term, alicole. There is evident in a series of hybrid forms the increasing of alicoles 

 through the twisting of the axis of a simple spike; the reappearance of suppressed spikelets; 

 the increase, crowding, and association in pairs of alicoles, forming the typical ear. Some 

 structural features of the latter can be better explained by the theories of fasciation, or "re- 

 duced branches," for which, however, these forms offer no supporting evidence. [See Bot.
