the endophyte, but the nucleus of the cell remains intact." The 

 duration of the gametophyte is apparently unlimited, so long as 

 fertilization does not take place. The young sporophyte con- 

 sists at first mainly of the primary leaf and root, which are tra- 

 versed by a single axial vascular strand. A stem apex is de- 

 veloped at an early period, although it remains relatively incon- 

 spicuous. 



The pala does not occur in cultivation, to the writer's knowl- 

 edge. It undoubtedly would grow successfully under humid 

 fern-house conditions, as do many other Hawaiian ferns. M. 

 fraxinea Smith, which ranges from west Africa to New Zealand, 

 is cultivated in American conservatories. The Hawaiian pala 

 would likewise give a magnificent tropical effect in northern 

 greenhouses. It deserves attention. 



PLEISTOCENE PLANTS FROM TENNESSEE AND 

 MISSISSIPPI 



By Edward W. Berry 



I have published, from time to time, brief accounts of Pleisto- 

 cene plants from our Atlantic and Gulf states as they have passed 

 through my hands, since the amount of material likely to be 

 available does not warrant a more comprehensive treatment. 

 For this reason I wish to place on record the following new oc- 

 currences. 



It is to be hoped that the distribution of our floras in the era 

 immediately preceding the present be considered by botanists 

 dealing with the existing flora. Even in the present unsatis- 

 •factory state of our knowledge of Pleistocene plants, woefully 

 behind that of other civilized countries, much is to be gained in 

 insight and many pitfalls may be avoided by looking back of the 

 present. 



This note relates to small collections made by Bruce Wade 

 in 191 5 at Adamsville, McNairy County, Tennessee, from 

 next to the highest terrace of the Tennessee River (elevation 

 about 500 ft.), and by E. W. Shaw from the Loess just west of
