Geogr. Distr. Madagascar (Poivrel Bot9in\); Comoro- Isles (Bojerl Boirinl Grey\). Cultivated in 
Europe. 
This species, according to Boivin " a shrub 6 fret high," has the longest leaves of the 
whole genus, some of them measuring 12-14 inches, and having petioles normally com- 
posed of five joints. The width of these joints is very variable, and imparts a different 
look to different specimens. Hence the many synonyms of this comparatively new plant. 
P. Powreanum, DeCand. is one of the broad-jointed forms, but not specifically different 
from the genuine P. Comorense. P. Bojerianum, var. ? elongatum, DeCand. is the same ; 
for the " beard " sometimes observable at the junction of the petioles is simply a fungus 
that establishes itself upon some specimens.
