RIDLEY. 
A tall stout herb 2 to 4 m tall, with a stout rhizome, the bases of 
the stems swollen. Leaves coriaceous, usually reflexed, glabrous, oblong- 
lanceolate, the apex acute, cuspidate, base rounded, nearly or quite 
sessile, 30 cm long, 8 cm wide; ligule rounded, entire, reticulate, hairy, 
8 mm long; sheath ribbed, hairy above. Inflorescence terminal, 30 
cm long, the base of the peduncle covered with a long, papery, linear- 
lanceolate bract 15 cm long, the rachis above flexuous. Flower-spikes 
about 8, distant, alternate, sessile, 5 cm long. Bracts linear-oblong, as 
long as the spike, 1 cm wide, pubescent, the margins ciliate. Flowers 
5 or 6 on stout peduncles. Inner bracts keeled. Calyx spathaceous, 
stiff, 5 cm long, reddish, split to the base on one side, apex with three 
short, silky points, pubescent. Corolla creamy, as long as the calyx, 
the tube cylindric, hairy, dilate at the apex, 3 cm long, the upper lobe 
hooded, lanceolate, mucronulate, 3 cm long, the lateral ones oblong, 
obtuse, keeled at the tips, mucronate. Lip shorter, obovate, subtrilobed 
at the apex, blunt. Stamen nearly as long as the upper sepal. Anther 
linear, curved, 2 cm long, the connective shortly prolonged above the 
anther-cells, rounded, entire. Style slender, filiform. Capsule woody, 
ovoid, dehiscing into three segments, 4 cm long, each segment 2 cm 
wide, yellow, glabrous.

Endemic; very common in thickets along streams in ravines etc. 
In some specimens the leaves are very much larger, oblong, and distinctly 
petioled, 60 cm long, 15 cm wide, with a terminal filiform point 10 cm long, and 
a petiole nearly 2 cm long, probably the lower or middle leaves on the stem, or 
perhaps a large form. The leaves on the growing plant are reflexed. 
Schumann puts this striking plant under the genus Alpinia, which I can not 
indorse. The genus, however, as he limits it is so wide that it contains many 
other plants at least as distinct as are most of the genera of Scitamineae. 
2. K. erucaeformis sp. nov. 
Stem 3 m tall, reed-like, with distichous, rather coriaceous leaves, 
which are linear, acuminate, glabrous, 34 cm long, 4 cm wide, the base 
broad; petiole none; ligule very short, rounded, glabrous. Panicle ter- 
minal, 10 cm long, with 6 branches. Branches cylindric, over 5 mm 
thick, covered with ovate, acute, keeled, ribbed, gray sheaths, pubescent 
when young. Pedicels short. Calyx spathaceous, with three small 
points, glabrous, 2 cm long. Corolla-tube shorter, the upper lobe ovate, 
2 cm long, the lower ones connate, oblong, ovate, rounded, thinner. Lip 
shorter, obovate, trilobed, lobes rounded, terminal one entire, thin-tex-
