the valley, as far as I have been able to ascertain, has ever had 
any plants of this species in cultivation or has ever seen any in 
cultivation in this vicinity. The ray-flowers are a beautiful pink, 
varying sometimes to lavender or even whitish. The plants are 
more slender, the inflorescence smaller and not as flattened, and 
the foliage somewhat different than in A. millefolium. The in- 
dications seem to point to a mutational origin of the colony from 
the latter common species. Occasionally plants are found which 
seem to show intermediate characters, and often the flowers while 
pink at the beginning of anthesis will fade out to a dirty white 
later on. 
On the crest of the Second Mountain, in a grassy overgrown 
clearing in the forest, there was discovered an extensive stand of 
Robinia viscosa. The trees are dense—so dense, in fact, that in 
some places one can only with great difficulty force one’s way 
through—but never attain a height of more than about 6 or 7 
feet. Thorns are practically obsolete, and the branchlets and 
petioles are extremely viscid. In the middle of June the flowers 
appear and make a gorgeous sight. Although not noticeably 
fragrant they are of a beautiful pink color. No one in the valley 
has ever had any of these trees in cultivation and the nearest 
cultivated tree of this species with which I am acquainted is in 
North Plainfield—beyond the valley, and a good five miles away. 
About five years ago another southern species of locust, R. hispida, 
Was discovered by the writer in a sandy woods southeast of Mt. 
oly in the southern portion of the State, but was never again 
rediscovered on later trips to that general vicinity. 
At the base of an old spruce tree near the long-deserted and 
overgrown remains of what used to be one of the oldest houses 
m the valley, was discovered a large colony of Hieracium mur- 
Rusts, a European species only recorded from three or four other 
localities in the United States and never before from New Jersey. 
€ plants bloom profusely during the first week in June and for 
* considerable time thereafter, making a very handsome appear- 
ance in the dense shade beneath the branches of the towering old 
evergreen, The colony is fully ten feet in diameter and contains 
over a hundred well-developed plants. The very peculiar shape of 
ect leaves is characteristic of the species. The pout ae 
Sea inches tall and naked or with but a single leaf. The basa 
are subcordate or subtruncate and strangely angulate-
