FERGUSON: CONTRIBUTIONS TO FLORA OF LONG ISLAND 199 
var. Morrowi Gray Kissena Flushing. Border of 
swamp. Native of Japan. 
“ Standishii Roslyn. Hilly woods. Native of 
China. Only escape known to 
Mr. Alfred Rehder of the Arn- 
old Arboretum who kindly 
named the last three species. 
LOBELIACEAE. Lobelia Family 
Lobelia Dortmanna L. Riverhead. Great Pond. In pro- 
fusion in 6 inches to a foot of 
water on white sand bottom. 
CICHORIACEAE. Chicory Family 
Nabalus altissimus (L.) Hook. Roslyn. Border hilly woods. One 
colony. 
Hieracium venosum L. 
ee marianum Willd. 
The typical H. venosum of the manuals, a slender, almost 
glabrous plant with few stem leaves is wide-spread on Long 
Island in shady woodlands. In more open dry and sterile pine 
barrens what the writer believes is the same species is more pubes- 
cent and rougher and on the open rolling wind-swept downs at 
Montauk, the plant varies from almost typical venosum through 
almost every possible gradation to almost typical marianum of 
the manuals, leafy and with long pilose hairs on stem and leaves, 
floccose pubescence and abundant glands on stem and inflores- 
cence. In the Hither Woods, Montauk, a mile from the open 
downs and separated by the depression of Fort Pond, the writer 
has found typical woodland H. venosum. 
Mr. E. P. Bicknell has kindly examined these Montauk 
plants and describes them as intermediate in varying degree 
between H. venosum and H. marianum, one plant being quite 
typical marianum, and as being similar to the plants of Nan- 
tucket found on open ground. On Nantucket, Mr. Bicknell 
found no typical venosum. For a complete description of the 
Nantucket plants, see Bulletin Torrey Bot. Club 42: 552-3. 
Dr. F. W. Pennell examined most of the Montauk plants 
and named them venosum. He doubted that marianum occurred 
in our area.
