Dr. Gray informs me that the plant Is quite rare. This, however, 

 is not the case at and south of San Diego, where it is rather common, 

 but appears to have been overlooked heretofore. The same is true 

 of Echidocarya Californica and Harpagonella Palme ri.

Adventitious leaf on Dandelion, — I have found to-day a dande- 

 lion ( Taraxacum Dens-leonis) with a well-marked though small leaf on 

 the otherwise naked scape. It is three inches below the involucre.

Abnormal Growths in Ferns. — The following notes are from ob- 

 servations on specimens collected during the present season on 



Staten Island: 



Pierisaquilina L. — Branches of the frond showing a great tendency 

 to bifurcation. In the specimen figured, one of the branches is three 



times bifurcated, and many of the pinnae show 

 the same tendency. In another specimen the 

 pinnules are remarkably crenate and finely 

 undulate on the surface, as if passed through a 

 fluting-machine, with many edges fringed- ^ 

 These two varieties were found in a limited 



locality, near Tottenville, in company with the 

 var, caudaia. Hook.,* gradually merging by every 

 intermediate stage into the typical form. 



Osmunda cinnamomea,!., — A fertile frond in 

 which the upper half is composed of very much 

 constricted sterile pinnae ; apparently approach- 

 ing var. frondosa. Gray, which is, however, dis- 

 tinguished by being fertile above and sterile 

 below, the very opposite of the specimen in 



question 



Found near Garretson s ; one speci- 



men only. 



Aspidium acrostichoidcs^ Swartz, var. incisum, Gray. — A great 

 many forms seem to be included under this variety. In some of the 

 fertile fronds every one of the pinnae is constricted, and covered 

 with fruit throughout its entire surface. From this extreme there is 

 every intermediate stage to the typical form. In some, the tips only 

 are fertile, in others, the fruit is scattered over the surface promiscu- 

 ously, and in rare cases is arranged in regular rows as in A. ynargin- 

 ale, Swartz. Only two localities have thus far yielded these forms; 

 near Four Corners and Egbertville.
