A Lycopodiaceous Seed-Like Organ . 
but the microsporange has no integument. These structures are 
always found in association with a very peculiar type ot vegetative 
structure in Hough Hill as well as in Dulesgate material. Hence 
it has been suggested by Dr. Scott on these three grounds, (a) the 
leaf-border one cell thick, (b) the position and structure of the 
ligule, and (c) the association with the said vegetative organs, that 
these integumented sporangia may be the reproductive organs of 
Miadesmia membranacea , a plant described and named by Bertrand 
in his paper “Sur une nouvelle Centradesmide,” Association 
fran^aise pour PAvancement de la Science, 1894, p. 588. Unfor¬ 
tunately, when Bertrand wrote, the reproductive organs were 
not available.
