1906] Sanford, — x\.splenium elienoides in Massachusetts 113 



The following sjiecies, discovered by the late Isaac Holden, was 

 •distributed under Nos. 1007 and 1163; the description, given with the 

 latter nvnuber, is as follows : 



1163. Lyngbya (Leibleinia) subtilis Holden n. sp. 



" Filaments attached by the middle to other algae; free ends cylindri- 

 cal or somewhat tapering; trichomes pale green, somewhat torulose, 

 .003-.0045 mm. diam., articulations 1-3 to 1, usually 1-2 diam. long; 

 terminal cell rounded, sheath thin, delicate. 



Attached to various marine algae, Bridgeport, Connecticut; and 

 along the coast to Maine. The filaments vary considerably in size; 

 the general habh is not unlike some of the smaller species of Plectonema, 

 but no branching has been observed."

A Station for Asplenium ebenoides in Massachusetts. — 

 On the 30th of September, 1905, I drove from Canaan, Connecticut, 

 where I was stopping, to Ashley Falls in Massachusetts. The day 

 was so hot that collecting seemed almost useless. On crossing the 

 Massachusetts line I was relieved, however, to find shade, which at 

 least looked cool. Crumbling abutments reached from the cliff 

 towards the road. The hollows between were filled with greensward 

 and the crevices in the rocks were full of all the lovely things that 

 like limestone crannies. From one to another I hurried and peered 

 like a mortal under a fairy spell. Walking-leaf, ebony and maiden-

 and all most daintily set. In the rich soil between the back of the 

 rocks and the river grew huge tufts of Christmas and evergreen wood- 

 fern and on an occasional limestone outcrop small and very intensely 

 colored purple clift'-brakes. I said to myself 'IHere we have the right 

 soil and an abundance of Asplenium ebeneum with Camptosorus 

 rhizophylhis elbowing each other; and whether Asplenium ehenoides 

 is or is not a hybrid, I would like to hunt every inch of this place for 

 a root of it, if I had the strength and two weeks time." Just then, 

 up over my head on a ledge, a difference in the form of a fern attracted 

 my attention, and after a scramble I actually had found the little 

 plant in question. It was a small root, to be sure, but unmistakable 

 in its identitv and within the limits of Massachusetts, where so far
