fa6ls mentioned by MEYER seem slightly to suggest 
that there has been some such error. He writes that it 
occurs ' in forests by the Aroabisci Creek' [in sylvis circa 
rivum Arowabischikreek~\ ; and also that, f he thinks, he 
has known the fruit under the name of Aguire' [Fruc- 
tum, nisi fallor ; sub nomine Aguire vidi]. Now, the 
only Astrocaryums of this se6tion which seem to be 
present on the Aroabisci Creek are A. tucuma, Mart: 
A. tucumoides, Drude, and an intermediate form between 
these two locally known as A rapeepi. Of these the one 
known throughout the colony as acque-ero (which 
evidently is the same word as the Aguire) is A. tucuma, 
Mart : or, as Professor Trail suggests, a variety of 
A. tucuma, Mart. It may be fairly assumed, therefore, 
that the A. aculeatum of Meyer is not the palm here 
known as acque-ero (or aguire). It is, however, just 
possible that it is that very similar form to acque-ero 
which is locally known as arapeepi, of which I have 
not as yet been able to secure any botanical determina- 
tion. 
SCHOMBURGK, it should be added, represents the 
A. aculeatum of Meyer as growing on the lower Esse- 
quibo and flowering in August and September. 
A. gynacanthum, Mart : 
This occurs, according to SCHOMBURGK, in the 
Canakoo and Humirida mountains, flowering in October 
and November. I know nothing personally of this type 
form, which is represented in the more accessible parts 
of the colony by its variety Munbacca, Mart., which 
variety, however, Martius regarded as a separate 
species.
