These Lophozias have been illustrated in various publications, but for 
two reasons I have figured them again ; for the student as a handy reference 
as well as for the sake of showing their comparative size. One magnifica- 
tion having been used, namely, X22 in all figures of plants; X70 i n all 
figures of leaves: X365 in all figures of cell structure. 
Lophozia Marchica was drawn from material, No. 172 Hepaticae Ameri- 
canae-Jungermannia Novae-Caesareae. Collected by Dr. A. W. Evans, 
Atsion, New Jersey, Aug. 1892. Also from material collected by Miss C. C. 
Haynes, Great Island, near Elizabethport, New Jersey, Aug. 2, 1902. 
Lophozia bicrenata. Collected by Dr. W. A. Evans, Huntington, Fair- 
field Co., Conn., March 8, 1906. Herb. Sulliv. Moss Chap. 
Lophozia excisa. Collected by Dr. A. W. Evans, Peter’s Rock, North 
Haven, Conn., May 5, 1906. Herb. Sulliv. Moss Chap. 
Lophozia Marchica (Nees.) Steph. Bull, de l’Herb. Boissier, II. 2:48, 1902. 
Stephani has recently reduced to this species, as a synonym, Jimger- 
mannia Mildeana Gottsche,* a form which most European writers have con- 
sidered distinct If this reduction is made, and it certainly seems justifiable, 
then the writer’s J. Novae-Caesareae ,f although recognized by Stephani, 
should apparently share the same fate. Accepting L. Marchica in this broad 
sense it is now known from three New England stations: Beach Mt., Mt. 
Desert Island, Maine ( E . L. Randy. Woods Holl, Massachusetts (. A . IV. E.)\ 
East Haven, Connecticut (A. IV. E). The species is essentially a bog-plant 
and is commonly found creeping through tufts of Sphagnum; in some cases 
however the plants may be completely covered with water, while in other 
cases, especially when growing in sandy bogs, they may be exposed to dry- 
ness. The plants vary markedly according to the amount of water which 
they receive, a liberal supply producing elongated stems with scattered 
leaves while a scanty supply produces short stems with closely crowded 
leaves. The cell-strucjbure is also variable. Protected and shaded leaves 
show thin and delicate walls, while leaves exposed to the sun show thickened 
yellowish walls with more or less conspicuous trigones. A single leaf in fact 
may show these variations in cell-structure. The dark purple stems which 
are characteristic of typical L. Marchica are paler in some of the other forms 
and sometimes show no trace of purple: in other cases the color is limited to 
the bases of the rhizoids and the adjacent parts of the stem. Underleaves 
are occasionally present in all the forms among the stem-leaves, but they are 
often very few in number and have the appearance of being abnormal or 
adventitious. Floral underleaves or bracteoles are of course invariably 
present. Plate IX. Figs. 1 — 4.
