24 AMERICAN FERN JOURNAL 
Lycopodium adpressum (Chapman) Lloyd & Under- 
wood. Not listed by Aikin or Sollers, but found by the 
writer at Glen Burnie over twenty years ago. 
Lycopodium tristachyum Pursh. This plant was first 
seen by the writer in Maine and New Hampshire. It 
was a great surprise to find it near Rockville, Md., not 
far outside of the Washington area. It has not been 
seen near Baltimore. 
SELAGINELLACEAE. 
Selaginella rupestris (L.) Spring. One station at 
Loch Raven on the Gunpowder River is so far above the 
new level of the water that it is safe. The region is now 
a game refuge and any violator of the law would have a 
long, roundabout, cross-country walk to get to the 
plants. The species was listed by Aikin. 
ISOETACEAR, 
As far as the writer knows, no species of Isoetes has 
been found, although there are many places that seem 
to be ideal for these plants. 
Of the species listed by Maxon, seven have not been 
found, but there are four, or possibly five (Botrychium 
simplex) in the Baltimore area which do not occur in the 
District of Columbia. In addition there are two well- 
marked varieties, Osmunda cinnamomea glandulosa and 
Botrychium obliquum oneidense, which are not mentioned 
by Maxon. The first of these should surely be found, 
as it is a Coastal Plain plant which has been collected 
in Mississippi and New Jersey, as well as in the type 
locality. 
It did not seem worth while to include above a num- 
ber of less marked, and perhaps entirely vegetative 
forms, which occur: such for instance, as the different 
forms of the “lady fern,” or a depauperate form of 
Dennstedtia punctilobula which B. D. Gilbert, against
