(P. geniculatum) occurs among the cells of the cortical layer of species of 
Laminaria, and is also referred to the Chroolepidae. In the same paper a 
new Ulvella (U. prostrata) is described, which is epiphytic on Iridaea lami- 
narioides.—J. M. C 
Insect galls of Michigan.—Coox has published a list of 59 species of 
insect galls from Michigan, 31 of them being new to the state. It includes 
representatives from all the orders of insects that contain gall-makers except 
the Coleoptera. As there are about 1200 known insect galls in North America, 
this list of 59 is only a beginning for the state of Michigan.—J. M. C 
Suspensor in Helminthostachys.—Lanc” has discovered that Helmin- 
thostachys possesses a massive suspensor closely resembling that of Botrychium 
obliquum described by Lyon. Since CampBe tt has recorded the same struc- 
ture in Danaea, it is becoming evident that a pee among pteridophytes 
is not a pecoiacity of the Lycopodiales.—J. M. 
Two embryo sacs in Fritillaria.—Lechmere?} has added Fritillaria to the 
short list of monocotyledons that occasionally develop two megaspore mother 
cells‘in an ovule. In this case (F. messanensis) the two enlarged mother cells 
are figured as lying side oe side, in immediate contact, both nuclei being in 
the synapsis stage.—J. M
