Bactris armata, Barb. Rod. (l.c., p. 27, no. 5).—* Stipiti 
mediocri; petiolo ad basim invaginante, aculeis subflavis ad extremi- 
tatem nigris vestito, supra vaginam paulo aculeato; frondibus indi- 
visis, cuneatis, bifidis, ad margines sinuatis, ciliatis, ad paginam infe-

The above description applies in every point to specimens of DB. 
chetospatha, Mart., collected by fiiyabl? at Ayrad, on the Rio Negro, 
and on the Barrs. de Cararaucu, on the Amazon (Trail hb. Palm. 37 
& 87); Iam therefore disposed to regard B. armata, Barb. Rod., as 
a synonym of B. chetospatha, M 
B. palustris, Barb, Rod (Le., p. 36, 25).—Having in my col- 
lection (Trail hb. Palm. 14) specimens 0 “of this Palm named by Dr. 
Rodriguez himself, I have been able to determine it.to be B. didentula, 
Spruce (l.c., p. 15 
s to the species is be baad a by Dr. Rodriguez additional 
to dais remarked on or in my former-paper, I can offer no re- 
marks tending to alncidats the ekien in 
so difficult a genus as Bactris descriptions of new species to be 
of value should be clear and full, and should be drawn up only from 
specimens bearing spadix and spathes, at /east, as well as leaves; if 
provided with flowers and fruit, so much the better, as these are abso- 
lutely necessary to determine with precision the position in the genus 
of a new species. Neglect of these rules simply tends to add to the 
difficulties of the subject, and to introduce still more confusion where 
there is already too much.

This is a much larger and stronger plant than the old D. diflorum, 
Sw. — a of the Soars species has a much longer nail, the three 
lacin all acute, the middle one much the longest, there is no 
endalass keel on n ds middle line nor papillar zone on the base of the 
middle lacinia, which surface has, however, some short hairs. I have 
-seen the ee e British Museum. The species has lately been 
confounded wi th the Javanese ms sereta: appencrcioes by Swedish autho- 
rities.
