Serra de Genecinó, and again in the mountains at the source of the Rio 
Grande de Jacarepaguá, both in the province of Rio Janeiro. The 
ample and accurate description and plate show it to be a new and re- 
markable species, belonging to a section of the genus distinguished 
both by its general habit and by the form of the fruit and venation of 
the wing, as well pointed out by Dr. Allem&o. This section, which 
may be called Tipuana, includes the M. grandiflorum (Benth. in Hook. 
Journ. Bot. vol. ii. p. 67), and M. Tipu*, a hitherto undescribed spe- 
cies found by Tweedie in the Parana. 
2. On the native name of the Eugenia pedunculata, or Ibápytonga of 
the Brazilians ; by I. J. Matta. (Section of Indigenous Languages.) 
The author discusses and corrects the spelling and consequent ety- 
mology and meaning of this name as given by A. de St. Hilaire after 
Maregrav and Piso. He shows that it should be Iddpytanga or Vbdpy- 
tanga, or fruit with colour, not Fbipytanga or Ibipitanga, which can 
only mean child (or rather fetus or infant) of the earth. 
3. Ferreira spectabilis, a new genus of Leguminose ; by Dr. Allemdo, 
with a plate. 
This is another large forest-tree, of which I am not aware that we 
have any specimens in our herbaria. With the fruit very closely re- 
presenting that of the Macheria of the above-mentioned section Ti- 
puana, it has the inflorescence and flowers of a Bowdichia, only much 
smaller. It must therefore, as proposed by Dr. Allemio, constitute a 
distinct genus of SopAoree, next to Bowdichia. The wood is known 
by the name of Sepepira amarella, Sepepira or Sebipira being the name 
generally given to the Brazilian Bowdichie. 
4. On the structure and functions of the excretory hairs of the Bra- 
zilian Urtiga braba, or Urtica nitida of Velloso; by Dr. Allemdo, with 
a plate. UNE
