On earth or on earth over rocks, especially in high and open places. 
Examined by the writer from Washington and Alberta (Bruce Fink), Van- 
couver Island (J. Macoun), Alaska (Trevor Kincaid). J. Macoun records 
from quite a number of localities throughout British America, Clara E. Cum- 
mings from many localities in Alaska, and Dr. Wainio adds California. This 
gives a general distribution throughout British America and Alaska, and 
from two states on the Pacific coast. This is the form coccocephala (Ach.) 
Wainio Mon. Clad. Univ. i: 204. 1894, which is found in Europe, Asia and 
South America. 
Cladonia bellidiflora Hookeri (Tuck.) Nyl. Syn. Lich. 221. i860 
Podetia elongated, cup-bearing, destitute of squamules (or finally sparsely 
squamulose). 
Recorded from Newfoundland and western arctic America by Dr. 
Wainio, and Clara E. Cummings reports it from several localities in her 
Lichens of Alaska. Known also in Europe, Asia and South America. 
Cladonia bellidiflora ramulosa Wainio Mon. Clad. Univ. 2; 210, 1894. 
Podetia quite short, about 10-20 mm. long and 0.7-2 mm in diameter, cupless 
and apices quite obtuse, radiately, fasciculately or dichotomously branched 
at or near the apex, with divaricate and quite short branches ; destitute of 
squamules or sparsely squamulose. 
Recorded from Finland by Dr. Wainio and from Alaska by Clara E. 
Cummings, Of this plant Dr. Wainio says, “ Habitu subsimilis est Cl. cris- 
tatellae Tuck., sed sine dubio e Cl. bellidiflora est evolute.” 
The illustration of Cladonia deformis is from No. 66, ‘ ‘ Lichenes Boreali- 
Americani,” and that for Cladonia bellidiflora is from a collection made by 
the writer at Glacier, British Columbia.

NOTES ON NOMENCLATURE IX. 
Elizabeth G. Britton. 
Part 229 of Brotherus’ Mosses in Engler and Prantl Pflanzenfamilien 
was received on October 25th, 1907. It includes pages 961-1008, completes 
the Hookeriaceae and takes up the Hypopterygiaceae , Helicophyllaceae , 
Rhacopilaceae and Leskeaceae. 
All but the last are tropical or subtropical in their distribution with one 
remarkable exception: Hypopterygium Canadense Kindb., from Queen 
Charlotte Island, British Columbia, is the only representative of this genus 
further north than Mexico or Cuba. Through the kindness of Professor 
Macoun, I have recently seen the type specimens and they undoubtedly 
belong to this tropical genus. It is one of those anomalous cases of distri- 
bution which finds its parallel at Killarney, Ireland, where a filmy fern and 
one of the Hookeriaceae , Cyclodictyo7i Icetevirens , are unique examples. 
This may be a survival of a tropical flora extending northward to the Yukon. 
Rhacopilum tomentosum is known to occur in Louisiana and will probably 
be discovered in some other of our Southern States. It ranges throughout 
the West Indies also.
