5. Alaria Pylaii (Bory) Grev. L if-(

Stipe 2-4 cm. long, terete; rhachis flattened, about twice the
diameter of the stipe, passing directly into the midrib; blade short
and broad, with broadly cuneate or truncate-cordate base, 2.5-3.5 dm.
long, 1-2 dm. wide, thin, membranaceous; midrib 5-8 mm. wide; sporo-
phylls 16-24 in number, 8-10 cm. long, 2-4 cm. wide, obovate, with
slender pedicels.

Growing on stones in the upper sublittoral belt, in the vicinity of
Prince William Sound and Kadiak Islands, Alaska.

The type locality of this species, is Newfoundland and the type
specimen is in the Herbarium of the Museum of Paris, and is labeled,
Laminaria Pylam. It was collected by De la Pylaie in 1817. The
specimen is evidently an old one, more or less battered, and has some-
what broader sporophylls than the measurements given above, other-
wise our specimens from Orca agree fairly well with the type and
until more data can be obtained from field study we are placing our
plants somewhat doubtfully under this species.

The type of Agarum Pylaii Bory in Herb. Bory shows a plant with
a short stipe, thickly placed, short but broad sporophylls, and a
broad blade, broad to even cordate at the base. Our specimens agree
sufficiently to be considered a geographical variety of this species.
