NOTICES OF BOOKS. 287 
Carlea (p. 216), referred to Onagrariee, is a species of Symplocos ! 
and as far as we can judge from the description Leucymmea (p. 211), 
referred to Memecyleæ, is another Symplocos ; but on this point we can- 
not speak with certainty, as we do not possess Helfer’s plants. 
Corynostigma (p. 218) is a true Jussieua, closely allied to J. nervosa. 
Botryoropis (p. 220) is the well-known Barringtonia acutangula. 
Strakea (p. 221) is a Bragantia, closely allied to, if not absolutely 
identical with, B. corymbosa, Griff., and if distinguishable from Bra- 
gantia, as proposed by Griffith, it should take his name of Asiphonia. 
Blepharochlamys (p. 245), generically distinguished from Mystrope- 
talum as being dicecious, is the very plant upon which Mystropetalum 
was founded, and is essentially moncecious, as appears even in the figures 
and descriptions quoted by Presl, which he cannot have seen. 
Cardiostegia (p.249) is a mere variety of Brotera bracteosa, Guillem. 
et Pers., or at any rate a species very closely allied to it; and Webb has 
shown, in the ‘ Spicilegia Gorgonea’ (Niger Flora, p. 111), that Brotera 
cannot be distinguished generically from Melhania. 
The changes of names among Piperacee will probably, where they 
are worth adopting, have been anticipated by Miquel’s valuable labours 
on that difficult tribe. The Antidesmata described p. 232—235 will be 
found to be illustrated in a far superior manner in Tulasne's admirable 
monograph in the * Annales des Sciences Naturelles,” third series, vol. xv. 
P- 180, which ought in point of fact to have precedence over the 
* Epimeliz.’

This is one of those important memoirs, which, ie ak friend Dr. 
Harvey’s ‘Nereis Boreali-Americana, owes its appearance to the “Smith- 
sonian Institution,” and comes under the general head of “ Smithsonian 
Contributions to Knowledge.” It mm a list of all the species detected
