1899] Clark, — Additions to the flora of Amherst, Mass. 165 
9. Plantago patagonica gnaphalioides. A common weed near the 
Agricultural College in 1890. 
IO. Rumex sanguineus. Not uncommon. 
II. Pogonia affinis. A single specimen of this rare orchid was 
found on the north side of the Holyoke range about three-fourths of a 
mile from the * Notch" and six or seven hundred yards from the 
“Old Bay" road, May 31, 1899. A number of specimens of P. ver- 
ticillata had been seen and one or two collected, but this specimen of 
P. affinis, though in similar soil, was several hundred yards from the 
nearest of them. It was growing on a dry wooded bank in the shade 
of hemlocks and was the only plant in that immediate vicinity. 
There were two dried stalks attached to the same root with the living 
one. The specimen answered perfectly to the description of P. affinis 
in the Manual and also to the figure and description in Britton and 
Brown's Illustrated Flora of the Northern States, etc., and was very 
obviously different from Z. verticillata. To avoid any possible error, the 
specimen was sent to Dr. Robinson at the Gray Herbarium, who con- 
firmed the identification. The specimen is now in that herbarium. 
12. Iris germanica. A small patch of this handsome iris was 
found south of Mt. Toby, in a swampy bit of ground, on the west side 
of the Central Vermont railroad, very near the track, in June, 1899. 
The plant seemed thoroughly established and the large yellow and 
brown flowers were very conspicuous. 
I3. Scirpus sylvaticus digynus. Not at all uncommon in swampy 
places. 
14. Calamagrostis confinis. Collected at Locks Pond in June, 1899. 
15. Eragrostis Purshit. Quite common near the Central Vermont 
railroad tracks. 
16. Poa a/sodes. Collected several times in North Amherst in 
1898 and in 1899. 
The following plants are given in the list, but these additional notes 
concerning them may not be without interest. 
Leontodon autumnale. Not at all uncommon now. 
Moneses grandiflora. Collected in 1893, in pine woods on the 
north side of Mt. Toby. 
Conopholis americana. A number of specimens were collected on 
Mt. Toby, in June, 1899. 
Phalaris arundinacea picta. Quite a patch of this handsome grass 
is established in a bit of swampy ground beside the Sunderland road, 
about half a mile above North Amherst. AMHERST COLLEGE.
