the result of a re-examination of ne s slides of Lepidostrobus, 
undertaken at the mance of Dr. D. H. Scott. is object an 
endeavour had been to make out, x "possible, at least some distinct 
' forms; but he had found great difficulty i in determining whether the 
observed srutaral sg nes in isolated sections were really of 
specific value or n He considered it ae to adopt pa vga 8 
Lepidostrobus Oldham for a common type of structure, and by com- 
parison to describe three marked variations. A clearly distinet 
orm he described as a new species under the name Lepidostrobus 
foliaceus. 
Ar the meeting of the Linnean Society of London on Feb. 2nd, 
. 8. Salmon read a paper entitled “‘ Notes on the genus Nano- 
mitrium Lindb.” This s genus had mae — regarded as cleisto- 
carpous. Examination of fresh specim . tenerum showed, 
however, that the capsules possessed a distinct zone of specialized 
cells—delicate, narrow, and transversely elongated—clearly marking 
off the upper part of the capsule as a lid. The same structure was 
found in the original specimens doliceted by Breutel, in Mitten’s 
. N. synoicun 
and N. Austini agreed with N. tenerwm in possessing the zone of 
differentiated cells, and in these species, although no opened capsules 
were found, the author expressed the belief that a complete separation 
aid in affecting the dehiscence. 1e above-mentioned structure 
satisfactorily accounted for the apm a genoa which had been 
b 
bserved by various authors, aud figured by Sullivant. N. equi- 
noctiale showed no differentiation in sia cells of the capsule-wall, 
and was truly cleistocarpous. nflorescence of this species 
proved to be polyoicous (autoicous+dioicous), In N. megalosporum, 
also, no differentiated cells occurred. Contrary to what had been 
stated by Philibert, the ae er of this species was found he possess 
stomata, and generally to show a structure similar to that of 
f 
and considered that the former genus should be limited to N. tenerum, 
N. Austini, and N. synoicum, referring N. acon ot pe (and perhaps 
also N, aquinoctiale) to Hphemerum. The essential character of the 
genus: iagap spe: was the presence of a ce of differentiated cells, 
remarked “that, since his paper had been written, he had noticed 
that, in the last part of = Ors ganographie der Panik: Goebel h
