Olus calappoides, p. 86, t. 20^ 21. 
The younger Biirman (Fl. Ind. 240) quotes the Olus 
calappoides (p. 86) for the Cycas circinalis of Linnaeus, 
by which this great naturahst meant the Falma/arinifera 
Japonica, Setitsou Japonensihus of Breynius (Fl. Zeyl. 
393), as producing sago, although he quotes as synony- 
mous the Palma prunifera Japonica of the Hortus Mala- 
baricus (iii. 9, t. 13—21). Now, this quotation is errone- 
ous ; for, in the places referred to, Rheede describes the 
Todda panna, one of the most common productions of the 
coast of Malabar; and although he alleges that it also 
grows in Japan (p. 12), where its stem produces sago 
(p. 13), I have no doubt that this is an entire mistake, (see 
the Commentary on the Sagus genuina, and Buchanan's 
Mysore, ii. 469) ; for Thunberg refers the Tessio, or Sotits, 
of the Japanese, if that be the same with the Soteetsou, 
Setitsou, or Soteetsou, to the Tetsios of Rumphius, which 
will be afterwards mentioned. 
But farther, the proper Olus calappoides of Rumphius, 
described in page 86, is not figured in the tables 22 and 
23, as Burman would have it. The male plant is repre- 
sented in tables 20 and 21, and Rumphius gives no figure 
of the female ; but it is from the form of the female spadix 
chiefly, that the species of Cycas can best be determined. 
In the text, however (p. 87), Rumphius describes this very 
clearly, — " Extremum petioli, e quo fructus dependent, 
semulatur planum pueri manum seu cristam galli from 
whence we may probably conclude, that the Olus calap- 
poides (p. 86, t. 20, 21) is nearly related to the Cycas re- 
valuta^ as described by Sir J. E. Smith, in the Linnaean 
Transactions (vi. 312, t. 29, 30) ; but this, it is admitted, 
is the Olus calappoides sinensis (p. 92, t. 24), which Rum^
