P: C Calaguala J—Leaves lanceolate, very entire, margins re-_ 
volute; spots of fructification disposed in a quincunx, solitary 
and parallel. 
Root — Round, somewhat compressed, slender, horizontal, 
creeping and flexuose, covered on the under surface with long, 
branching, dark-grey fibres, and on the upper surface with febiide 
disposed in two rows alternating with each other; of an ash co- 
Jour on the exterior side, and covered almost throughout with 
spreading scales, and on the interior of a bright green colour, 
furnished with many small nerves, which extend throughout its 
centre. After slow desiccation it pecomce on 1 its exterior surface 
of a dark ash colour, after the scales or scurf h een re= 
moved, and when cut it exhibits in the interior a compact sub- 
stance, in some degree resembling that of the sugar-cane or 
citron, and of a pale straw colour more or less intense. The 
taste is at first sweet, followed by a strong disagreeable bitter, | 
somewhat viscid. It may readily be masticated without any re-

kind of rancid oily odour. ©

having instead of them indistinct | yeins g, mé

and on the posterior side with fructification from the middle ‘to 
the apex in those fronds which have attained their full size ; 
from the middle downwards i is destitute of them. In the young
