Foliicolous Spherie. 
In my pps published in the last number of this Journal, the references 
to the Plates are wrongly given. In all instances where XLIX. is named it 
should have been L., and where L. is quoted it should have been LI., except in 
the “ Explanation of Plates," wherein the figures are correct.

Having misread one of speed s labels “ Tigu Island " for “Tiger Island,” 
and inc a new species of Piper from Honduras, P. Tiguanum 
(Journ. of Botiniy, s nA 218), I now beg to substitute for that unfortunate 
name that of Tigerian

NEW PUBLICATIONS. 
Manuel de la Flore de Belgique. Deuxième édition, considérablement 
augmentée, Par F. CnfPIN. Brussels: Mayolez. 1866. Svo, 
pp. 384. 
The first edition of M. Crépin’s handbook was published in 1860, 
and is pretty well known in this country. The six years which have 
elapsed since its issue er been a time of great activity amongst the 
Belgian botanists. As M. Crépin writes :—“In 1862 the Royal 
Botanical Society of «iud .was founded, and placed at its head a 
man* who linked the past with the present, and upon whose activity 
and devotion it could rely. Altogether only four years old, it has 
already done good work, and made itself favourably known abroad. 
Its members have increased at every meeting, and its reports are be- 
coming more and more interesting and voluminous." Of this activity the 
volume before us bears full testimony. That part of it which relates 
in detail the distinctive characters and distribution of the species is 
almost doubled in extent. M. Crépin does not profess to characterize 
the subordinate critical forms, but of all the well-marked species, and 
of some that are not well-marked, he gives careful analyses on the 
dichotomous or Lamarckian plan, and a detailed sketch of the Belgian 
distribution of each with the special stations of the rarities.
