also from but one station. Naturally our interest during local trips 
largely centered about these last two supposedly rare species, and it 
was not long before a little active collecting showed them to be fre- 
quent about Philadelphia or even locally common. : 
Professor Fernald had encouraged us with the opinion that A. 
canadensis, A. occidentalis, and A. petaloidea ought to be extended 
south into our upland counties, so a trip in the middle of May, 1909, 
with Mr. S. S. Van Pelt into the glaciated area of N orthampton County, 
Pennsylvania, lying just south of the Blue, or Kittatinny, Mountains, 
held at least promise of some possibilities in Antennaria. In the 
Herbarium of the Academy of Natural Sciences we had seen a speci- 
men of A. canadensis from the Catskills and so during this trip we had 
this species continually in mind. The hope of finding it was not 
realized here but a tall form with large heads and strikingly handsome 
white petaloid bracts (suggesting, in general, 4. fallax with round- 
tipped leaves) collected at the foot of the Big Offset north of Bangor, 
and again between Johnsonville and Mount Bethel, proved to be A. 
occidentalis — a northern species heretofore known, in the eastern 
part of its range, only as far south as western Massachusetts and New 
York. 
The work of Mr. Harold W. Pretz in Lehigh County, Pennsylvania, 
has given us additional information on the local distribution of 
Antennaria and has also added another northern species to our local 
flora. Through two seasons he has collected extensively and has 
generously allowed me the use of his material. To Mr. Pretz belongs 
the credit of making known in our region Antennaria petaloidea — a 
species not previously recorded south of New York State. His 
station is at Corning, in the red-shale district of the extreme southern 
part of Lehigh County, at the head of the Perkiomen Valley which 
supports so many interesting and often local species. Two other 
collections of his give additional evidence of 4. occidentalis at locali- 
ties still farther south than the Bangor stations. The one, of handsome 
staminate plants with characteristic basal leaves, Professor Fernald 
1 Here occur two of our most southeasterly stations in Pennsylvania for Luzula 
saltuensis, as well as stations for L. campestris var. multiflora which finds the extreme 
limit of its range on the southeast near Philadelphia. Among species of character- 
istic occurrence may be mentioned Juniperus communis, Oryzopsis racemosa, Poly- 
gonatum biflorum, Corylus rostrata, Acer spicatum, Lonicera dioica — all types which 
come into the Philadelphia area from the north or northwest and which become rare 
and localized south or southeast of the Perkiomen Valley.
