28 CHROOLEPIDACEAE 
Delesserias belong to Nitophyllum, as was soon recognized by 
Montagne himself, and it is possible that they represent different 
conditions of a single species. They will be discussed later on in 
the present paper. In ''Delesseria phylloloma," the endophyte 
is so abundant that the lower and older parts of the thallus have 
a greenish hue caused by its presence. Mr. Cotton’s forma 
Nitophylli was described as occurring in various British species of 
Natophyllum, the figured type being in N. Hilliae.

“Оп rocks at top of cliff on the ocean side of Isla Vieja, Bahia 
de la Independencia," July 21, 1907, Coker 225. “СІН probably 
300 feet high. As the wind, blowing from the ocean, swept up this 
cliff a very light cloud was continually formed, which dissipated 
at once as it blew over the top. The rocks were thus kept suffi- 
ciently moist for the growth of the alga.” Though hardly to be 
considered a marine plant, this alga was included with the others 
sent by Dr. Coker andis here commented upon with the others. 
The plant differs in several respects from the wood-inhabiting 
Г. polycarpa from the island of Juan Fernandez, as originally 
described by Nees and Montagne, yet would doubtless fall within 
the limits of Hariot’s broad conception of this species. It differs 
from the original description of Т. polycarpa in the cell walls

his жак was issued in parts and 1841, the date of the title page and the date 
cited by Hariot in his discussion of the synonymy of Trentepohlia polycarpa, is the 
actual date of publication of only the last 53 pages of Hooker & Arnott’s work. Part 
II, comprising pages 49-96, is reviewed by Wikstróm in his Jahresbericht for the 
year 1832 (p. 38) and this date is assigned to it by B. Daydon Jackson also (Jour. 
Bot. 31: 298. 1893).
