Homologizing plants and insects.—In attempting to homologize the 
various parts of plants and insects, JANET? has succeeded in proposing several 
additions to our already overloaded vocabulary. The sporangium of Mar- 
chantia contains “‘isogynospores” and ‘‘isoandrospores,” while that of Selagi- 
nella contains ‘‘macrogynospores” and “macroandrospores.” The vocabulary 
consists mostly of words like these, which are easily understood but unnecessary 
and not at all likely to become a permanent part of our burden. The plant 
atest te consists of a gametophyte, beginning with the spore and end- 
ing with the “‘gynogametes” and “androgametes,” and a sporophyte, beginning 
with the zygote and probably including the rest of the life history, although 
the table gives the sporangium (called the “‘gynosporangium’’ and “‘andro- 
sporangium”’ in Selaginella, and = Te and pollen sac in spermatophytes) 
as the final member of this genera 
The insect is an ‘‘orthozoite,”’ eeciine of a ‘‘gametozoite” and a “sporo- 
zoite”’ generation. The gametozoite coayaiata begins with a generative cell 
(cellule Eeoitale) which produce “‘gonads,’”’ gametangia, and finally “‘gyno- 
gametes” and “androgametes.”’ The sporozoite generation begins with the 
fertilized or parthenogenetic egg, and includes the rest of the life history. 
Several years ago the reviewer tried to show3 that, in animals as in plants, 
generations are characterized by the haploid and diploid number of chromo- 
somes. JANET’s paper is based upon current knowledge rather than upon any 
new evidence, ‘Loetugaiies we agree with him, or rather he agrees with us, that 
there is an alte g in animals.—CHARLES J. CHAMBERLAIN. 
Flora of New Guinea.—Another volume of the botanical results of the 
Dutch scientific expedition to New Guinea (1907 and 1909) under the auspices 
of Dr. H. A. Lorentz has now appeared.4 The first part of the botanical 
report was reviewed in this journal.s The collaborators are as follows: S. H. 
Koorpers, L, RADLKOFER, A. PULLE, J. VALCKENIER SURINGAR, E. ROSEN- 
sTocK, MAX FLEISCHER, TH. VALETON, J. J. SMirH, A. ENGLER and K. Krause, 
C. LAUTERBACH, J. PERKINS, and L. Diets, 72 families and 292 genera being 
represented, including 599 species, 153 of which are new. Three new genera 
are published as follows: Capitularia (Cyperaceae), Gjellerupia (Opiliaceae), 
and Nouhuysia (Guttiferae). Most of the families are introduced merely to
