3io Stapf. — On the Sonerileae of Asia. 
The rhizome emits short creeping or succumbent branches 
with 2-3 pairs of leaves above the ground and a terminal 
inflorescence which overtops, more or less, the leaves. The 
rhizome is much shortened and tuberlike, or it consists of a few 
tubers which are connected by slender internodes. The stem 
near the nodes is covered with reddish spreading bristles like 
those of vS. squarrosa and S'. arguta. The leaves are of the 
type of S. Griffithii. The flowers are rather larger than in 
this species, the anthers 4*5-5 mm. long and acuminate, the 
capsules ovoid-ellipsoid with a thin pericarp and rather faint 
ribs. 
10. S. molaefolia, Hook. f. Moulmein. 
A much stouter plant than any of the former. The innova- 
tions are, as far as the material allows us to conclude, of the 
same character as in S. khasiana. The leaves are crowded 
at the ends of the branches of the rhizome. They are larger, 
and of a firmer texture than in the remainder of the group, 
but of the same type. The inflorescence is cymose, first 
umbel-shaped, but afterwards circinoid in consequence of 
the lengthening of the sympodium. Flowers and capsules 
are as in khasiana. 
In all the species mentioned hitherto the leaves are desti- 
tute of transversal venation. The tertiary nerves are faint, 
sometimes hardly visible, and rise at acute angles from the 
middle and the secondary nerves. They are curved towards 
the apex and branch into an exceedingly tender network of 
venules. Only in 5 . secunda , maculata , and picta, the outer 
two or three secondary nerves are more or less distinctly 
joined by nervules which diverge at more obtuse angles, thus 
approaching slightly the typically transversal nervation of the 
following species.
