at Brooklin, occurring where there is the least semblance of a sandy 
beach. There are also several plants of the same variety on Swans 
Island. 
RANUNCULUS LAXICAULIS (T. & G.) Darby. This was collected 
in a muddy pond hole at South Deer Isle, its easternmost station. 
Norton reports the plant from apparently the same locality. 
CAMELINA SATIVA (L.) Crantz. This plant occurs sparingly as a 
weed in the northern section of Maine, but has not been reported on 
the coast east of York. It was fairly abundant in a potato field at 
Brooklin. 
ERYSIMUM CHEIRANTHOIDES L. This has a similar range in the 
state. [t was found in profusion on a sandy barrier beach at Flyes 
Island, Brooklin. The only other coastal station in the two herbaria 
is Cumberland. 
SISYMBRIUM OFFICINALE (L.) Scop. The second Maine station for 
this plant is a sandy beach at Swans Island Head. Previously it had 
been known only from Brownville. 
CRATAEGUS JONESAE Sarg. This thorn, described from Mount 
Desert and very common on the western shore of Penobscot Bay, is 
equally common at Brooklin and on the islands. It has been also 
recorded from Washington County. 
LATHYRUS PALUSTRIS L., var. PILOSUS (Cham.) Ledeb. The dis- 
tribution of this plant as shown in the two herbaria is interesting. It 
occurs from Eastport along the coast to Mount Desert but is unrepre- 
sented from the area between there and the coast of Massachusetts. 
Itis very abundant in the Penobscot Bay region, both on the mainland 
and the islands. 
RUBUS PUBESCENS Raf., var. PILOSIFOLIUS A. F. Hill. The pubes- 
cent variety of the dwarf raspberry was first collected at Brooklin. 
EMPETRUM NIGRUM L. "This is reported as ‘local’ by Norton and 
‘rare’ by Graves, but it is very common on headlands and exposed 
granite rocks, more so on the outer islands than on the mainland. 
Corema Conrapit Torr. This is extremely common on rock out- 
crops at Swans Island and at Brooklin, where it is found, not in a bog 
in the Central Tract as Graves states, but on rocks at the edge of the 
bog. It has been previously reported from Isle au Haut. 
ILEX VERTICILLATA (L.) Gray, var. PADIFOLIA (Willd.) T. & G. This 
was found very frequently at Brooklin and on the islands, though 
there had been no specimens from the state in the herbaria before.
