Descriprion.—The leaves apparently are less spinous than those of the type; 
the rhachis towards the end of the leaf has only rudimentary spines on the 
sback. The fruits are as in the type but somewhat smaller. 
HanrrAT.— West Oeram: Native name “Sagu Rotang." I mention this variety 
because it is recognised by the natives, but the specimens of it seen by me are 
too poor for judging of its ,value. The fruits are similar to those of the forma 
typica and well conformed externally, but have the seed reduced to only its 
hypertrophic integument. It is not to be confused with Rumph’s Sagu duri Rotang, 
which corresponds to VAR. mecracanthum, and has small fruits.

Descriprion.—It is doubtless a variety of M. Rumphi, having a more slender 
trunk, the leaves with longer spines on the petioles, and a larger fruit. 
Rumph writes that no other Sagu tree, has spines so long, that its trunk is 
not so thick as that of “Sagu Tuni,” the typical form of M. Rumphw, but that 
it is slender and similar to that of Cocos nucifera; that its “Gabba Gabba” (the 
petiole of the leaves used for the walls of the houses, etc.) do not last so long as 
those of M. Rumphi, and that its leaves are narrower, of thinner structure, more 
deeply green and more brittle, so as to render them less fit for “ Ataps" (roof- 
ing) and that its trunk affords less starch than * Lapia Tuani” (M. Rumphit type). 
The fruits are described as of the size of a hen's ezg. obliquely excavate in the 
lower part. He adds that it is the least esteemed of all known varieties or species 
of Sagu tree. 
Haprrat.—Amboina at Huconalo or Rumatiga, Leytimor and Hite. Native name

Osservations.—I have not seen specimens which could. with certainty be referred 
to this variety. Under the name of “Sagu Makanaro” I have received a variety
