dium aureum, L., which grew in the same hummock. Upon investi- 

 gation, I was surprised to find that they grew upon a live-oak tree. 

 Except in one instance, where a single plant of this fern grew inside a 

 hollow burned stump of some swamp tree, I had never seen or known 

 that P. aureum would grow on any tree but the Palmetto, except 

 where in two or three cases, roots had been transplanted to congenial 

 homes on the trunks of cultivated date-trees here in town. One of 

 the trunks of this live oak had been cut down, and upon this cut place, 

 where the wood was softer from consequent decay, the fern had ob- 

 tained a resting-place and had gone vigorously to work. This fall I 

 visited the tree again, and the fern was flourishing finely. Further 

 search in the woods rewarded me by showing me a second fern grow- 

 ing on another live oak tree under the same conditions, and I ob- 

 tained good specimens from both trees. A fact which added much to 

 the interest of finding the aurcums in these unexpected places is that 

 there are no large Cabbage Palmetto trees in the vicinity from which 

 the fern could have been transferred, and the fern itself is also very 

 scarce in this region. 



P. incanum on the trees, and Osmunda cinnamomea on the ground, 

 are the other representatives of the fern family in the same hummock. 

 The O. cinnamomea is very common everywhere beside the "branches," 

 and has been bearing an abundance of fruited fronds during the past 

 two months. 



Polypodiintt incauinn is by no means particular as to its habits, 

 growing on live-oaks, hickory and cedar trees. — Mary C. Reynolds,

Carnivouous Plants. II. — Experiment No. 2. -An ant was 

 placed upon a leaf near the center of the disk, at 2 o'clock, June 

 4th, 1879.— 

 15 min. no change. 

 30 " the submarginal tentacles (reflexed at first) now nearly at 



right angles to the blade. 

 90 " only a slight change. 



4 hrs,. marginal tentacles moving slightlv. 

 18 " the submarginal tentacles nearest the specimen much in- 

 flected, but as yet do not touch it. The marginal tenta- 

 cles had moved only slightly from list note. 

 38 " submarginal and central teniacles inflected, but only the 



latter touching the specimen. 

 48 " about the same as the last. 

 66 "a slight rcflexing is apparent. 

 73 " tentacles reflexing. 

 117 " tentacles nearly all reflexed except a few of the central ones. 

 144 " change only slight. 



157 " some of the submarginal and a i^"^ central tentacles have 

 again inflected, but for what reason, I cannot tell. 

 With a lens I could see no other animal or exciting substance 

 of any kind upon the leaf!
