THE JOURNAL OF ROTANT 
Prof. W. A. Setchell has made two additions to his algo- 
logical output— Parasitic Floridece, II. and A Revision of the 
West North American Species of Callophyllis (University of 
California Publications in Botany , x. Nos. 6 & 7, pp. 393-401, 
1923). The former contains preliminary diagnoses of seven new 
species and three new genera— Faucheocolax, Phodymeniocolax, and 
Plocamiocolax: the second comprises preliminary descriptions of 
fourteen new species of Callophyllis from the Pacific Coast and a key 
for their readier discrimination.—A. Gr. 
Two posthumous papers, Notes on a Collection of New Zealand 
Hepaticce and More New Zealand Hepaticce ( University of Cali¬ 
fornia Publications in Botany , x. Nos. 4 & 5, pp. 307-392, pis. 83— 
109, 1923), by the late Mr. W. H. Pearson of Manchester, have 
recently been issued, and probably represent the last research that 
he was able to carry to completion. They give an account of the 
collections made by Prof. W. A. Setchell in the Northern Island 
of New Zealand in 1904. Out of some 55 species studied, fifteen 
and a variety prove to be new to science; and several other species 
are redescribed and figured.—A. Gr. 
At the meeting of the Linnean Society on Nov. 1, a paper was 
read by Mr. Sydney Garside on the forms of Fly pax is stellata L. f. 
(. Ianthe stellata Williams; see Journ. Bot. 1901, 289). Four varie¬ 
ties were distinguished, one of them as yet undescribed; these have 
constant vegetative characters, but the flowers show a considerable range 
of colour variation of a “continuous” kind. Important cytological 
characters of the upper epidermis of the perianth lobes were described, 
with particular reference to the remarkable iridescent areas which 
occur in some varieties. The characters of the four varieties were 
briefly outlined, and the view was expressed that these are not distinct 
species, as some of the earlier botanists supposed. Support for this 
view is based upon the structure of the ovary; breeding experiments 
have not yet been made. Habitat may considerably influence the 
size of the plant, but the varietal characters remain constant. 
At the same meeting Mr. W. N. Edwards read a paper “ On the 
Cuticular Structure of the Devonian plant PsilophytonP Specimens 
of Psilophyton princeps Dawson, from Gaspe (New Brunswick) in 
which the cuticle is preserved, show that as in the early land plants 
of the Bhynie Chert the stem is provided with stomata. These 
resemble in size and distribution the stomata of Asteroxylon but 
have cuticular thickenings which have not so far been observed in 
either Asteroxylon or Phynia. No stomata were seen on the highly 
cuticularized spines, but these spines do not resemble intumescences 
of Phynia , and Psilophyton is probably nearer to Asteroxylon. 
As intimated on p. 270, the Report of the British Bryological 
Society contained a notice of the late William Inoham, to which 
we are indebted for some of the following particulars :—He was born 
at Manchester in 1854 and died at York, where most of his life had 
been spent, on May 25 of this year. He was a B.A. of London 
University; he was Organising Inspector of Church Schools in the 
diocese of York, and later on the staff of the York Education Office.
