plants containing similar series of colors. It is inferred that crosses between 
white-flowered plants should result not infrequently in progenies of all purple- 
flowered offspring, or of purple and white in the ratios 1:1, 3:5, or 1:3; butas yet. 
these results have not been found.—J. M. C. — 
Jurassic flora of Normandy.—Licnier:" has added a number of new species 
to the rich jurassic flora of Normandy, that are suggestive of relationships con- 
cerning which real knowledge is very much desired. The Filicales are represented 
by species of Lomatopteris and Linopteris, and the Equisetales by a species of 
Equisetites. The cycadean forms, however, are of chief interest and abundance, 
and it would be a great gain to know. definitely what the numerous species of 
Zamites and Otozamites represent. The conifers are represented by species of 
Brachyphyllum, Pachyphyllum, and Conites. 
The memoir is undated, but its reception in March 1910 suggests recent 
publication.—J. M. C 
ry and apogamy in Trichomanes.—GrorGEViTCH:? has investigated 
Trichomanes Kauljussii, whose apospory and gemma production was described 
by Bower in 1894. The branching filamentous prothallium bears sterigmata 
(singly or in tufts), at the ends of each of which is balanced a gemma. The 
development of prothallia from these gemmae is described in detail, and antheridia 
were observed developing directly upon the gemmae, sometimes associated with a 
prothallium on the same gemma. This transition from sporophyte to gametophyte 
is accompanied by no reduction in the number of chromosomes. Counts were 
made in both generations and at different stages of mitosis, and always approxi- 
mated 80.—J. M. C a 
Parasitic fungi of Wisconsin.—In 1884 TRELEASE published a list of the 
parasitic fungi of Wisconsin, and supplementary lists were issued by Davis in 
1893, 1897, and 1903. Now a fourth supplementary list has appeared.* It 
contains a list of 76 forms occurring on hosts not previously recorded; and 113 
forms not reported heretofore from the state. The latter list includes 9 neW 
species and varieties in the following genera: Ascochyla, Cercospora, Cylindro- 
Sporium (2), Gloeosporium, Phyllosticta (2), Ramularia, and Septoria. This 
record in reference to 189 forms indicates what interest and persistence can do- 
for any area.—J. M. C.
