Catalogue de la Flore des Isles Azores. Par Henri Drouet. 
Paris, 1866. Pp. 153. 
The author has compiled the list of the plants of these islands from 
his own herborizations and from the published lists of previous authors. 
He has greatly increased the number of the species — for his catalogue 
comprises 727 species, three-fourths of which appear to be added by 
M. Drouet and his companions. It is to be regretted that he did not 
pay more attention to the synonymy. The number of species must 
be somewhat reduced when those are eliminated which are here in- 
serted on the authority of former writers who have employed different 
recognized synonyms for the same plants, and whose names figure in 
the list as different species. Nor has M. Drouet always exercised 
ordinary care in working up his own plants. He has specimens in his 
herbarium of his plants, "No. 573. Blechnum boreale, Swartz. — Hab. 
San-Miguel, Fayal, Flores Pico, et la plupart des autres isles. No. 
573. Blechnum Spicant, Roth. — Hab. San-Miguel, Terceira, dans les 
bois. Peu abondant et tres-variable." P. 131. We might quote 
others equally careless.

Professor de Barry has succeeded Dr. Schlechtendal as editor of ' Botanische 
Zeitung,' as well as in his chair at the University at Halle, and Dr. Garcke 
takes charge of Dr. Schlechtendal's other journal, the < Linnsea.' 
M. Pouchet, of Rouen, 1ms observed that a small proportion of the seeds 
of Medicago A mericana are able to withstand an uninterrupted boiling for four 
hours without losing their vitality. In the greater proportion of the seeds 
thus treated, the contents had swollen and broken the integument, and the 
water necessarily became mucilaginous, but others successfully withstood the 
high temperature, the outer integument resisting the water, so that when they 
were sown, they sprang up in the course of from ten to twenty days. 
We understand that the Botanical Society of France have arranged to hold 
an International Botanical Congress in Paris, during the time of the Great 
Exhibition, to which botanists of all countries will be invited. The Congress 
J^l open on the 26th of July, and will last for a month. Meetings will be 
held every Friday evening at the Society's rooms, 84, Eue GreneUe, St. Ger- 
main. On other days during the period, visits will be made to the Exhibition, 
to the Museum of the Jardin des Plantes, to private collections ; and excur-
