STARCH CONTENTS OF EVERGREEN LEAVES DURING THE WINTER 
AND AT OTHER TIMES 
I first examined a number of evergreen plants, including 
angiosperms, gymnosperms, and pteridophytes, for the starch 
contents of the leaves in August. The results generally corre- 
spond to the investigation of Meyer.* Thus, generally speaking, 
monocotyledons have little or no starch in the leaves, while 
dicotyledons, gymnosperms, and pteridophytes are found to be 
fairly rich in starch. 
Then, during several months, from August to the following 
spring, I examined about eighty evergreen plants for their leaf- 
starch, the material being usually taken twice or three times a 
month. The leaves for examination were taken from various 
parts of the plants, the healthy and full-grown ones being 
selected. In many cases they were taken from several individ- 
uals of the same species. To determine the starch contents four 
to eight cross-sections were made from a single leaf, and for 
such sections five to ten- leaves were used. Of eighty species 
examined the following seventeen were found to lose the starch a 
from the mesophyll during the coldest part of the winter : 
Ilex rotunda. Asarum Blumei. * 
Ilex latifolia. Ephedra vulgaris. 
Magnolia compressa, Picea hondoensis 
Magnolia grandiflora. Podocarpus Nageia. 
_Ternstroemia japonica. Aspidium falcatum. : 
_ Daphne odora Polypodium ensatum.* — 
Andromeda se icuic. Polypodium lineare. * - 
Aucuba japonica. Gymnogramme japonica.” — 
Geranium acutarium. * 
* Herbaceous plants. 
As it takes too much space to describe the r 
the species above mentioned, I shall give oy, t 
rotunda, as a representative.
