MINOR NOTICES 
The nuclei of Protista.—The name “Protista,”’ applied by HAECKER 
to the lowest animals and plants, has failed.to receive general acceptance, even 
among zoologists, and the forms are found under both the protozoa and 
unicellular plants. In any consideration of the phylogeny of the nucleus these 
forms must be of great interest, because the nuclei of the metazoa and of the 
higher algae and fungi are too highly differentiated to throw much light upon 
such a subject as the origin of the nucleus. A paper by HARTMANS deals almost 
entirely with the nucleus of protozoa and its significance as the forerunner of the 
nucleus of the metazoa. Botanists working with the nucleus in the lower 
algae and fungi, and especially with — cannot afford to overlook this 
paper.—CHARLES J. CHAMBERLAIN 
Symbolae Antillanae.°—In continuation of this important work Pro- 
fessor URBAN in cooperation with several eminent specialists has issued the 
second and third fascicles of the seventh volume. There are included descrip- 
tions of approximately 300 new species, several varieties, and a few new 
combinations The following new genera are proposed: Sarcopilea of the 
ia 
Asclepiadaceae, Ja oeapeamente of the Scrophulariaceae, and Shaferocharis 
of the Rubiaceae.—J. M. GREENMAN.

Root-tubercles of non-leguminous plants.—In an extremely long and 
somewhat obscure article, which is not made any clearer by the vague illustra- 
tions accompanying it, PEKLO? gives an account of his studies of the organisms

all esetntial details. Prxkto finds in the cells of the root-swellings of A/nus and 
Myrica masses of filaments with more or less radial arrangement and termi-
