DRAPARNALDIA 298 
During the first week of April, 1901, a visit to the station was 
made to get material for distribution, but owing to the lateness of 
the season no Draparnaldia had appeared. Before a second visit 
in May, the encroachments of civilization had so disturbed the 
brook that no vegetation remained, and it is to be feared that the 
station is permanently lost. 
It was, therefore, particularly pleasing to stumble upon this 
species during a field meeting of the Vermont Botanical Club in 
July. The reason for finding this species still vigorous after an 
extremely hot period, is probably that, in the Vermont bog, it was 
growing at an altitude of two to three thousand feet. 
DOUBTFUL OR LITTLE KNOWN SPECIES 
DRAPARNALDIA BILLINGSII Wood, Proc. Am. Phil. Soc. 11: 
143. 1869; Hist. F. W. Ale 208. pl. 14. f. 6. 1873. DeToni, 
Syll. Ale 1: 191. 1889. 
There is nothing in Wood's description which marks this 
species as especially different from the common forms. Possibly 
"it is to be identified with D. acuta. A fragmentary specimen 
bearing the name was seen in the Wolle herbarium. Chodat dis- 
poses of this species and D. cruciata Hicks as forms of D. plumosa 
without giving evidence of more knowledge of their character than 
may be gained from the unsatisfactory published descriptions. 
DRAPARNALDIA OPPOSITA (Lyngb.) Agardh, Syst. Alg. 59. 
1824. Kutz. Spec. Alg. 357. 1849 (sub Species inguirendae). 
Harvey, Ner. Bor. Am. 3: 71. 1857. DeToni, Syll. Ale. 1: 
194. 18809. 
D. plumosa opposita Lyngbye, Tent. Hyd. Dan. 190. AJ. 654. 
1819. 
It is very doubtful whether the form reported by Harvey was 
correctly named ; his description reads very much as though he 
had a form of D. plumosa. Both the description* and figure 
given by Lyngbye indicate a form very similar to our D. platy- 
zonata. 
The specimen issued by Miss Tilden as D. opposita (Am. Alg. 
12) was doubtless identified by the description of Harvey or of 
* * Ramis inferioribus subverticillatis ; penicillis brevibus, patentibus, oppositis ; 
articulis diametro subaequalibus, lineis linis longitudinalibus notatis."
