3 . Conocephalum conicum (L.) Dumort. 
This is possibly our most conspicuous as well as common hepatic. The 
large patches formed by its wide ribbon-like thallus, covering moist 
shady banks, where it grows, are sure to attract attention. Notwith- 
standing that it is so very common, I have never found it in fruit. I 
have found it only in the Piedmont region. 
4. Lunularia cruciata (L.) Dumort. 
This neat little hepatic is almost sure to be found in any old greenhouse, 
growing on the soil, generally among the ferns. 
5 . Marchantia polymorpha L. 
Another very common hepatic, but rather erratic in its behavior, found 
sometimes for years in a certain locality, only to suddenly disappear. 
Almost sure to be found on the hillside of any newly-cut road, espe- 
cially if such a road goes through moist wooded regions. It, however, 
does not seem to be over particular in its choice of habitat. I have found 
it growing on old ash heaps, on the pavements of our city streets, and 
even in the bed of a shallow stream. 
Metzgeriaceae. 
6. Riccardia latifrons Lindb. 
Rather rare, at any rate I have found it but once on a wet decaying 
log in a deep ravine in the Piedmont region. 
7. Metzgeria conjugata Lindb. 
Not at all uncommon on shaded rocks in deep woods. . Found thus far 
only in the Piedmont region. 
8. Pallavicinia Lyellii (Hook.) S. F, Gray. 
Very common, growing over mosses in swampy woods in our Coastal 
Plain. 
9 . Pellia epiphylla (L.) Corda. 
Another common hepatic, found growing on the ground in moist places 
of our Coastal Plain. I have found it also, 'but less frequently, in springy 
places among the wet rocks in the Piedmont region. 
10. Blasia pusilla L. 
Another fairly common hepatic, sometimes covering large areas. Found 
in situations similar to those in which Marchantia is frequently found. 
An interesting companion plant is Anthoceros laevis. In fact, wherever 
I find Blasia , I am sure of finding Anthoceros. 
J unger man niaceae. 
11. Nardia crenulata (Smith) Lindb. 
On earth among rocks in bed of a brook coming down steep hillside. 
Rather rare. 
12. Nardia obovata (Nees) Lindb. 
Rare. Found at the base of a large over-hanging rock, on moist earth, 
in Piedmont region. 
13 . Plagiochila asplenioides (L.) Dumort. 
On dripping rocks and around the base of trees in swampy ground
