has, the first and most carefully, analyzed and described Artisia as the pith 
cylinder of Lepidophloios, a genus generally considered in intimate relation 
to Lepidodendron or Lycopodiacee by Grand’ Eury, Goldenberg, Shimper 
and others; therefore, the reference of Artista to any kind of Conifers is as 
yet, it seems, unauthorized. I have treated the subject with some more de- 
tails in considering the general characters of the Carboniferous flora. 
[FLOWERS AND FRUITS OF CORDAITES. ] 
Under the name of Cordianthus, Grand’Eury has considered as evi- 
dently referable to Cordaites, the flowering branches known formerly 
under the name of Antholithes. The racemes of flowers described here 
with Cordaites mansfieldi, C. communis, and C. costatus, evidently prove 
this relation. For, if they are more slender and less developed than those 
which have been found separated from the stem, as the Antholithes, the: 
characters of these’ organs are evidently identical. They represent either 
male flowers, buds covered with imbricated scales, containing merely a 
powder which may be the pollen; or fertile flowers in smal] oval or 
round ovules. Of these we have only the following species referable to 
male flowers : 
CoRDIANTHUS GEMMIFER, Gr. d’H. 
Pl. XLVI, figs. 5 and 6. 
Buds sessile, upon a thick, simple raceme, broadly oval; scales imbri- 
cated, oval, obtusely pointed. 
This species, represented by fig. 5, corresponds to that of fig. 4, Pl. 
XXVI, of Grand’Eury. The second with longer oval lanceolate, more 
acute scales of a narrower cone, as represented by fig. 6, corresponds to 
fig. 6 of the same plate of Grand’ Eury. 
Of the fertile flowers, Cordianthus baccifer, I have not found any. A 
branch described and figured in the Geological Report of Illinois, IV, p. 427, 
Pl. XI, fig. 6, under the name of Schutzia bracteatu, Lesqx., bears on one 
side of the raceme cones identical by their characters to Cordianthus gem- 
mifer, while it has on the other a elosed bud or a round tubercle, borne 
upon a short, inflated pedicel, which appears to represent the round tuber- 
cles of Cordianthus baccifer. This, therefore, would imply the monoicity 
of these flowers, while all the specimens published by Grand’ Eury and other 
authors, represent only racemes with either gemmifer or baccifer flowers, 
and therefore indicate the inflorescence as dieecious. My specimens are not 
good and distinct enough to authorize a definite conclusion, as the bacci- 
form bud may represent merely the top of a gemmiform one,* whose basi- 
lar scales have been destroyed and detached by maceration. The remain- 
ing top, however, is exactly globular. By detaching the scales of the gem- 
mifer cones, I found under them a transparent, yellowish membrane, 
formed of elongated, equilateral, small meshes or areole, inclosing or sup- 
*Grand ’Eury remarks with reason, that these flowers are generally so much 
altered by decomposition, that it is rarely possible to fix the sex which they 
represent.
