We think Dr. Wallich will agree with us in referring this—the D. /obulosa of his valuable Cata- 
logue—to the JD. heterophylla of Smith and Swartz. Our specimens are indeed more pinnatifid 
than the description of the latter would allow; but we find that the fertile fronds vary in this 
respect, and sometimes so exactly correspond with the Zfwmata pinnatifída of Cavanilles, that 
we are entirely disposed to consider them one species. On a specimen now before us, there is a 
fertile frond with the lower half sinuate and dentated, whilst the upper half is truly pinnatifid and 
dentated.
