On the Morphology of the Sporophyte of 
Splachnum luteum. 
BY THE LATE 
J. R. VAIZEY, M.A., 
of Peterhouse, Cambridge . 
With Plates I and II. 
[After Mr. Vaizey’s death there were found among his papers a number of 
drawings, which were intended to illustrate his memoir on the Sporophyte 
of Splachnum luteum : a preliminary account of his observations had 
already appeared in the Proceedings of the Royal Society. There were also 
found a few sheets of manuscript, consisting chiefly of a description of the 
structure as illustrated by the figures, but the discussion of the morphological 
question which is indicated in the last paragraph of the paper in the Pro- 
ceedings of the Royal Society was not entered upon. It has been found 
possible, by putting together these fragments, to present them in a connected 
and intelligible form, so as to demonstrate the careful observation and 
draughtsmanship which characterised Mr. Vaizey’s work : excepting a few 
verbal alterations, the text, though rearranged, is entirely his own. The 
Editors are indebted to the Council of the Royal Society for permission 
to make use of the paper which appeared in the Proc. Roy. Soc. No. 274, 
Dec. 1888]. 
T HE investigations of Haberlandt \ published in the latter 
part of 1 886, together with the results of investigations 
of my own, which were then just completed, and communi- 
cated to the Linnean Society 2 early in 1887, convinced me of 
the importance of obtaining further knowledge of the highest 
development to which the sporophyte of the Mosses attains, 
as being likely to throw light indirectly on the phylogeny of 
the higher Cryptogams and Phanerogams. Inquiring into the
