6. Account of an Excursion to the Fazendo de Guawindiba, near San 
Gonçalo, with the description of a new genus of Artocarpeæ ; by Dr. 
Allemio. 
Soaresia nitida is the name the author here gives to what appears to 
be a good genus, allied in some respects to Pseudolmedia of Trécul. 
7. On the etymology of Maracuiá or Murucuiá, as applied to the Pas- 
sion-flowers ; by I. J. Matta. 
The detached papers by Dr. Allemáo are nine in number, each ac- 
companied by a plate. Eight are descriptive of seven new genera, be-- 
longing to Leguminose, Combretacee, Apocynee, Nyctaginee, Laurinea; 
and Zuphórbiacee. Their characters have been transcribed by Walpers, 
in the * Addenda Posteriora’ to the third volume of his * Annales Bo- 
tanices,’ and, after carefully going through these papers and the accom- 
panying plates, I cannot find that any one of them is otherwise than 
well founded. Would that the same could be said of the majority of 
the so-called new genera, with which some continental botanists have 
of late years been inundating the science ! 
The ninth paper contains a short notice of the labours of Dr. Manoel 
Arruda da Camara, a Pernambuco botanist, who died at a very early 
age, leaving behind him, under the name of * Centurias Pernambucas, 
a considerable number of drawings and memoirs, illustrative of the 
flora of that province. These papers have come into the hands of Dr. 
Allemáo, who proposes to publish them, commencing with the Cochlo- 
spermum insigne, here figured and described under Arruda da Camara’s 
name of Azeredia Pernambucana. Dr. Allemão vindicates the restora- 
tion of this name on the ground of priority, Arruda da Camara’s paper 
having been drawn up during the bishopric of Dr. José Joaquim de 
Azeredo Coutinho, to whom the genus is dedicated, that is, between 
the years 1798 and 1802. But these papers are stated by Martius to 
have been still in manuscript only in 1837, and the name of Azeredia 
cannot therefore be allowed to prevail over that of Cochlospermum, €S- 
tablished by Kunth in 1822, and ever since universally adopted. It 1s 
now a settled rule, that even the reading a paper before a scientific s0- 
ciety is not a publication sufficient to confer priority, until it be recorded 
in substance in the published proceedings of such body. ;
