(Symphoria albus [a] Raf. l. c. is à nomen nudum, applied to the Snow- 
berry quite without reference to V. album L., and Symphoricar pos albus

Koch himself (and wrongly ascribed to Rafinesque), likewise having no 
connection with the name Vaccinium album L.). Lonicera alba (L.)

Durie our field-work of 1911, a tiny Ruppia was collected in tidal 
pools at Norris Arm in eastern Newfoundland, which differed very 
strikingly from the ordinary plant which we had known as R. mari- 
tima. Later, after our return from Newfoundland, somewhat similar, 
but in some characters quite different, material, collected as an un- 
usual plant by Dr. B. M. Duggar on Naushon Island, was referred to 
us for study; and in the explorations of Prince Edward Island and the 
Magdalen Islands by Messrs. Fernald, Long and St. John a special 
point was made of watching Ruppia, with the result that they got 
several extreme plants such as we rarely see on the Atlantic coast of 
the United States. Examination of these plants and the material in 
the Gray Herbarium, the herbarium of the Academy of Natural 
Sciences of Philadelphia, and the herbarium of the New England 
Botanical Club, in the light of the recent treatments of the genus in 
Europe shows that we have in America many more well defined forms 
of Ruppia than has been generally supposed and that, to a great extent,
