indusium was described by Renault in B.forensis} but the subject is one that requires 
further investigation before any conclusion can be drawn. 
The diameter of the sporangia in the Pettycur specimen is from 280/x to 240 /x ; 
that of the spores about 25 fx , and that of the annulus cells from 50 /x to 60 /x. 
Group of four annulate sporangia in close association with a rachis of Botryopteris antiqua. 
i t indusium-like structure between two sporangia. (The palisade tissue at / is a foreign body, being 
a fragment of the sporangium-wall of Lepidostrobus Veltheimianus.') Drawn by Mrs. D. H. Scott, F.L.S. 
X about 100. (Scott Coll. 2496.) 
The specimen just described appears to heighten the probability that the 
sporangia of an Osmundaceous type associated with Botryopteris antiqua really be¬ 
longed to that plant; it thus seems worth placing on record, though evidence of 
actual continuity is still lacking.
