Like everything from the pen of Dr. Asa Gray, his genera and species 

 are worked out with great care and precision, and he often amends the 

 characters or con-ects the errors of others, with much judgment. Not 

 exactly so, however, in the case of the qucesfio vexata of the genus of 

 Myrtm TJgnl of Molina (genus JJgni^ Turcz., Eugenia, Hook, et Am.), 

 where, referring to our Bot. Misc. vol. iii. p. 348, he says, "Through 

 some mistake, the flowers are said to be quadrifid, and the peduncles 

 shorter than the leaf." It so happens that a living specimen of this 

 very species is before us, while reading this note of our friend, and it 

 has the flowers quadrlfid (^^ e. tetramerous), and the peduncle shorter 

 than the leaf. It is nevertheless true that they are not always so. 



Some of the unpublished plates are in our possession \ and we can 

 truly say, this fine work promises to be as honourable to the American 

 Government and the country, as it is to the able author.

Messrs. F. Dozy and J. H. Molkenboer are already favourably known 

 in the botanical world by their * Musci Frondosi inediti Archip. Ind.,* 

 etc., which is now concluded in six livraisons, quarto, with sixty plates. 

 The present publication is to take its place, illustrated with figures, of 

 which it is not too much to say that they arc admirably executed, on 

 the model of those of Bruch and Schimper's ' Bryologia Europsea,' and

with 



of accuracy which could not otherwise be looked for, especially in the 

 analysis and microscopic details. The five plates of the first number 

 are devoted to the illustration of six species of, it must be acknowledged, 

 a very difficult and, as now considered, extensive genus, Fissidens, most 

 satisfactorily figured and accompanied by full specific characters, gene- 

 rally some ten lines (of a quarto page) long, and equally careful des- 

 criptions and references to the plates ; and three other species arc des- 

 cribed, but not figured. But this, we hold, is not enough. In the
