Ohs. 1. — 1 have referred this species to the genus 

 Calyptronoma, Gries. (though doubtfully, owing to the want 

 of flowers), on account of the great resemblance that the 

 spadix bears to the spadices of Calyptronoma Sioartzii, 

 Gr., and of C. dulcis in the Kew Herbarium, as well as on 

 account of the fibres that occur in the mesocarp, in which 

 respect the fruits agree with fruits of C. dulcis at Kew. 

 I have never seen similar fibres in the fruits of any true 

 Geonoma, 



Obs. 2.— The leaves are largely used for thatch where 

 it occurs, as they are said to be very durable. I have 

 been told that it occurs on the rivers Jandiatuba and 

 Jurua.
