FLORA OF MOUNT DESERT. 
FUMARIA, L. Fumitoey. 
oo F. OFFICINALIS, L. 
—~ Waste ground, Great Cranberry Isle (E. & E.). Adventive 
from Europe.. 
CRUCIFERS. Mustaed Family. 
CARDAMINE, L. Bittee Ceess. 
C. hirsnta, L. 
Frequent in brooks and on pond shores. So far as known the 
Island plants are all glabrous, and in other respects do not cor¬ 
respond to the typical European plant. Whether our common 
American plant is not specifically distinct seems to be an open 
question. That it is so distinct, see N. L. Britton, Bull. Torr. 
Bot. Club, xix. 219. As, however, there appear to be inter¬ 
mediate forms, perhaps it would be wiser to give it only varietal 
rank. The Mt. Desert forms can perhaps be classified under 
the three following heads for convenience, although apparently 
there are no well defined dividing lines between them. 
(a) Forma Pennsylvanica. C. Pennsylvanica, Muhl. Gla- 
17, Li-ous; large and leafy; few, if any, radical leaves; pods linear; 
pedicels somewhat divergent. Roadside ditch between Town 
fervale Brook (Eand). 
" O) Like the last, but with widely divergent pedicels, and fiMF ^ 
thicker, much shorter pods. The most common form. Brook, 'jr 
Clark Valley ; Cold Brook ; Intervale Brook (Eand); — 
Doctors Brook ; Stanley Brook (Eedfield) ; — Deer Brook 
(R. & R.). 
(y) A form more nearly corresponding to typical G. hirsuta. 
Glabrous ; radical leaves rosulate ; pedicels erect or some¬ 
what spreading; style short and stout ; pods variable in 
length and thickness. Shores of Northwest Arm, Great 
Pond (Eand, M. L. Fernald). 
^ C. parviflora, L. 
Leaflets mostly linear; radical leaves few or none; pods 
linear, erect on spreading pedicels. In dry ground, or among 
moist rocks; rare. Little Duck Island; Flying Mt. (Eand).
