OTHER TERATOLOGICAL NOTES 



By S. B. Parish 



1. Foliar fission in Polystichian viunitnin. — A plant of this 

 fern, growing in the San Bernardino Mountains, exhibited in its 

 different fronds a wide range in the extent to which they were 

 affected by fission. This was very slight in some, but in others 

 the normal form of the pinnae was greatly modified. The 

 accompanying figure, from a drawing by Mrs. C. M. Wilder, 

 renders further description unnecessary. 



2. Polypliylly of the Gynecium in Wasliingtonia. — The ovary 

 of Washingtonia consists of three conjoined carpels uniting in a 

 common style. In a flower of W. gracilis two such ovaries, 

 entirely distinct throughout, were included in the same calyx.
