ture of the stomata of Casuarina confirm the conclusions of Treub and others 
as to the phylogeny of this genus; wherefore he concludes that such data 
constitute a valuable adjunct to the usual phylogenetic criteria.—C. R. B 
W. C. CoKER® has discovered that no sterile prothallial cell is cut off in 
the germination of the microspores of Cupressus (4 spp.), Taxus daccata and 
four vars., Juniperus (2 spp.), Chamaecyparis (5 spp.), Callitris (1 sp.), 
Cryptomeria japonica, and Thuja orientalis. In Thu uja the four megaspores 
were not found in the usual linear series, but in the regular tetrad arrange- 
ment.— J. M. C 
Miss MARGARET BENSON* has suggested a possible origin of the 
angiosperm flower from the “telescoping” of such an “inflorescence”’ as 
that of Gnetum, which also suggests angiosperms in its free sporophylls, 
nucellar structure, embryo sac development, and vegetative characters. It 
may be that the possible origin of angiosperms from Gnetum-like forms has 
been recently too lightly considered.—J. M. C. 
TWO RECENT PAPERS by Kiitster” recount the author’s experiments on 
regeneration from the hypocotyl of seedlings of Anagatlis coerulea and Lina- 
via Cymbataria. When the epicotyl was removed, shoots sprang from the 
hypocotyl, and showed a marked anisophylly. Detached cotyledons of 
Cucumis sativa produced both roots and shoots in a small proportion of cases. 
It is shown that anisophylly is not due to geotropism.—M, A. CHRYSLER. 
W. B. HEMSLEY has published some curious data in reference to 
Davidia, an endemic and monotypic Chinese genus usually placed in the 
Cornaceae. The seeds germinate while retained in the fruit, which has 
dehisced enough to expose them; hence from one to ten seedlings may be 
emerging simultaneously from a single fruit. Buds were also observed in the 
axils of the cotyledons.— J. M. C 
F. V. CovILLE” has given an account of the preparation of ‘“ wokas” by 
the Klamath Indians, once a staple farinaceous food of the tribe, and obtained 
from Nymphaea (Nuphar) polysepala, the great yellow water lily. The 
Klamath reservation is in eastern Oregon, and Klamath Marsh is estimated 
to contain about I0,000 acres of a solid growth of “wokas.”’ The plant is so
