times, and has already published a number of memoirs upon the subject. The 
Conspectus will be entirely in Latin, and will enumerate with full description, 
synonymy, and habitat, all the plants of political Greece, with its isles, and 
also of Epirus and Crete. The work will appear in eight to ten fascicles, 
preface, bibliography, and keys will appear with the last fascicle. The first 
one includes Ranunculacez to Alsinacez, and the sequence is that of Bentham 
and Hooker.—J. M. C. 
THE Last “Contribution from the Gray Herbarium of Harvard Univer- 
y” appears as Proc. Am. Acad. 35:307-342. Igoo, and contains four 
papers. The first is by J. M. GREENMAN, entitled “New species and varie- 
ties of Mexican plants,” and contains descriptions of twelve new species.— 
The second is by B. L. ROBINSON, entitled “Synopsis of the genera Jaegeria 
and Russelia.” The species of Jaegeria have been much confused with 
Sabazia, Galinsoga, Melampodium, and Spilanthes. Dr. Robinson recognizes 
nine species, two of which are new. The genus Russelia contains thirteen 
species, two of which are new.— The third paper is by E. B. Utne, entitled 
‘New Dioscoreas from Mexico,” and contains descriptions of two species and 
a new variety.— The fourth paper is by B. L. Ropinson, entitled ‘‘New 
phanerogams, chiefly Gamopetalae, from Mexico and Central America,” and 
deals chiefly with new species (twenty in number) and specific reductions in 
the genus Eupatorium.— ge ie Se 
THE fourth fascicle of Engler’s work on the genera and families of 
African plants ® has just appeared, completing the Combretacez. Notices of 
the preceding fascicles appeared in the BOTANICAL GAZETTE for January 1899 
and January 1900. In the third fascicle a synopsis of Combretacez and an elab- 
oration of the greatest genus, Combretum, were given. In the present fasci- 
cle the nine other African genera are presented, by far the largest being 
Terminalia, with 4 5 species, 22 of which are described asnew. The fascicle 
is a model of completeness and fine presentation, the plates and figures being 
especially worthy of commendation. The general conclusions in reference 
to the African Combretacez, apart from those littoral species which belong to 
the mangrove-formation, is that there is very little relation with either tropi- 
cal America or Madagascar, but that there is a rich development of endemic 
Sroups in the various plant-formations of tropical Africa.— J. M. C. 
JANET R. PERKINS has published a “ Monograph of the genus Molline- 
dia,” being a dissertation for the doctorate at the University of Heidelberg.
