page 90, these words are twice written as above, and on the same 

 page in the catalogue of the species they are respectively written 

 or printed Tapsus and Tapsiforme. 



For " Rhoeas" in the name Papaver Rhceas, Rhceas appears in 

 the errata not as an error, but as the corrected form. The former 

 is the spelling commonly adopted, for which there are doubtless 

 sufficient etymological reasons. 



We are pleased to see Heleocharis printed for our Eleocharis, 

 which British botanists pertinaciously print against all sense and 

 grammar. On the principles of the London dialect, the latter 

 form is defensible. A genuine Cockney aspirates all words be- 

 ginning with a vowel, and also omits the aspiration of all words 

 beginning with an h. According to this practice, Eleocharis is 

 Heleocharis, and the Belgian Heleocharis would be Eleocharis, 

 as pronounced by a Londoner. 



In this excellent manual of Belgian botany, there are two sub- 

 jects omitted, not accidentally, but on purpose. One is the du- 

 ration, and the other is the time, of the flowering of plants. 

 Both these points are well worked out in Cosson and Germain's 

 complete work on the plants growing in the environs of Paris. 

 It is probably true, as has often been remarked, that these sub- 

 jects are occasionally inadequately or erroneously treated ; still 

 they are missed, and we would rather see these statements im- 

 proved than abandoned. Imperfect information is preferable to 

 none at all, as " half a loaf is better than no bread." A map 

 would also be a desirable accompaniment to this Flora, but we 

 cannot have everything, and we are rather disposed to thank the 

 author for what he has given us, than to grumble because we 

 have not got more. 



M. Crepin's work is not only a complete precis or resume or 

 epitome of all that was known about the plants of Belgium, but 

 there are, it is believed, some not inconsiderable additions con- 

 tributed to the common fund of botanical information. Two new 

 forms or species of Hieracium have been observed in Belgium 

 .which is not particularly rich in plants of this genus ; one of 

 these has been distributed under the name H mosanum, and 

 further notice of it is to be expected. Bromus has also received 

 no little portion of our author's labours, and it is hoped that he 

 will embody his own discoveries and contributions to the science 

 in a form in which it could be published in the ' Phytologist,'
