siderably less carbonaceous matter that much progress can be 
made. All of my specimens have been sketched immediately, 
before becoming dry, so that they are fairly satisfactory; the 
specimens however might almost be thrown away as far as 
concerns their value as types. 
While usage would sanction the designation of poor speci- 
mens of doubtful botanical affinities as ‘‘ sp.” after referring 
them provisionally or otherwise to some genus, which prac- 
tice is supposed to obviate any undue definiteness on the part 
of the describer; the writer in these notes has followed the 
laudable practice of Professor Ward, as quoted above, in be- 
lieving that whatever is worth mentioning is worth a name. 
Acknowledgment is due Dr. Arthur Hollick, of the New 
York Botanical Garden, and Professor W. B. Clark, of Johns 
Hopkins University, for material assistance. The specimens 
are all deposited at the New York Botanical Garden. 
CONIFERAE. 
Geinitzia Endl. Syn. Conif. 280. 1847. 
This is an entirely extinct genus of the Taxodieae with 
several species on both sides of the Atlantic: G. cretacea 
Unger (Austria), G. formosa Heer (America and Quedlin- 
burg), G. hyperborea (Greenland), G. sp., from the Da- 
kota, and G. Jenney7 Font. from the Lower Cretaceous of the 
Black Hills. It was founded by Endlicher in his Synopsis 
Coniferarum to include certain forms referred by Geinitz to 
Sedites and Araucarttes and by Corda to Cryptomeréa. 
Among the former was Araucarites Retchenbacht of Geinitz, 
which Heer in 1868 identified with the living genus Sequoza. 
Since that date this plant has been almost uniformly called 
Sequota Retchenbacht, and many place Endlicher’s Geindtzta 
cretacea under it as asynonym. Others retain the older forms 
under Gecnztzia. Ward contends that the retention of the 
genus Geznitzza logically carries Seguota Reichenbachi with 
it into that genus as the type, while on the other hand the 
recognition of Seguoda Rerchenbacht logically abolishes the 
genus Geinitzra.
