82 T. Holm — Anemiopsis Calif ornica. 



Most of the species examined by this author possess isolateral 

 leaves ; several of these have hypodermal eollenchyma or the 

 niestome-bnndles are supported by real stereome. Ou the 

 other hand, Mr. Kearney observed a wrinkled cuticle and a like 

 distribution of stomata on both leaf-surfaces, both of which 

 characters, as we remember, are also to be observed in Anemi- 

 oj>si$. A similar result is reached when we compare the 

 species examined by Professor Warming,* none of which pos- 

 sess such striking peculiarities as those characteristic of the 

 Pi'jyeraceaz, nor do the features of his Halophytes in general 

 agree with those of our plant ; only a few points and of no 

 particular interest or of seemingly great importance may be 

 found common to both. As stated by Professor Warming, the 

 lack of stereome seems to be characteristic of the Halophytes, 

 so far as concerns their leaves, and only these have been exam- 

 ined. In this respect Anemiopsis would show some likeness 

 to the Halophytes, since the leaves contain very little stereome 

 and only near the midrib. But if we compare the other parts 

 of the plant, the stem and the petiole for instance, we then 

 observe this tissue to have reached a very high development, 

 especially in the flower-bearing stems and the stolons. 



It would, thus, appear as if Anemiopsis so far as concerns 

 the structure, gives a better illustration of one of the several 

 types of the Pijperacece than of any specialized type modified 

 in accordance w T ith the environment, halophilous for instance.
