MESOZOIG PLANTS OF NORTH CAROLINA. 107 



Group." The Palissya conferta is from the Rajrnahal Group of India, which 

 Feistmantel thinks is of Liassic age, but which contains so many Rhsetic 

 species that it appears to me to be of Rhsetic age. At any rate the North 

 Carolina plant does not seem to be a Walchia, and so long as it is not more 

 precisely known, it is perhaps better to consider it as a distinct species 

 which may bear the name Palissya diffusa. 



Walchia longifolius.

"Plant shrub-like, or large ami branching, stems striate, often nearly naked, 

 the smaller leafy; leaves long, acute, keeled, clasping, and tapering from near the 

 base, slightly decnrrent. Fig. 72 shows the leafy branches. * # * Sometimes the 

 branches appear to become naked, as in Fig. 73, and the termination appears of the 

 form represented, as if it bore a cone more elongate than that of the Voltzia. This 

 club moss is common at Lockville." 



The above is the account given by Emmons of this plant, which is 

 plainly a Palissya, and identical with the common Palissya of the Rhsetic 

 of Europe, viz., Palissya Brawiii, Endl. This plant from North Carolina 

 is precisely like the plant from India, from the Rajrnahal Group, which 

 Feistmantel calls Palissya Indica, and considers as a new species, though 

 very near to P. Braunii. It seems to me that the differences are too slight 

 to separate the India plant from Palissya Braunii, and that it is merely a 

 slightly different form. 



Emmons states that the leaves are keeled, that is, with one rib, but 

 does not represent the rib or keel in the figures. This is an illustration of 

 what was stated above of his neglect of the nervation of the leaves in his 

 figures. He represents in his fig. 7 J, PL LI, fig. 1, of this work, three 

 leafy branches of the plant as going off from a stout stem, but says that 

 they were not actually seen attached to a stem. I have omitted the sup- 

 posed main stem, and reproduce only the three branches, as these were 

 all that were actually seen. The club-shaped mass at the summit of fig. 

 2, resembles strongly the cone of Palissj'a. 



Walchia brevifolia.

" Plant slender, elongated, branchiug, leafy; leaves rather short, lanceolate, acute, 



tapering towards the base. This plant has some resemblance to Walchia hypnohles of
