This species seems to be represented by a single specimen 
of a small dichotomous branch from Lansing, Kan. The stem 
is Slender, only 5 mm. wide below the dichotomy, the bolsters 
elliptical or broadly elliptical, 214 to 3 mm. long, about one- 
third as wide as long, acute above and below, rounded at the 
sides. The leaf-scar is placed above the middle. 
Lepidodendron clypeatum (?) Lx. Pl. LI, fig. 5. 
A specimen referred doubtfully to L. clypeatum occurs in 
the collection from the Cherokee shales at Lansing. 
Lepidocystis Lx. 
Lepidocystis Lesquereux, Coal Flora, p. 454, 1880. 
Sporocystis Lesquereux, Coal Flora, p. 458, 1880. 
Lepidocystis sp. 
Spore-cases arranged spirally on a slender axis, oblong, one- 
half to one-third as wide as long, sessile, obtuse at both ends, 
close, overlapping each other, sessile without evidence of sub- 
tending bracts; spore-case covering numerous thin macro- 
spores, rounded on one side, triradiate on the other. 
The spore-cases described here are of the proportions and 
general appearance of the three isolated spore-cases figured 
by Lesquereux (loc. cit.) and referred to the genus Sporo- 
cystis, but without specific name. Their attachment in a 
spiral manner to an axis brings them within the genus Lepido- 
cystis, as originally characterized. It has been suggested on 
the evidence of association that the spore-cases belong to the 
large-leaved Lepidophyllum, and these are in turn referred by 
Goldenberg and White to trunks described under the name 
Lepidophloios. 
Formation and locality: Cherokee shales, Lansing.
