I. Spathes coriaceous, tubular before flowering, produced at the apex into a 
tail-like bristly tip. Outer spathe in the unopened spadices almost 
entirely enclosing all the others (in D. Loherianus, each gradually 
longer than that immediately below.) Mouth of the leaf-sheaths not 
armed with very long erect spines, or quite smooth. 
a. Outer spathe slightly shorter than the inner ones. 
* Leaf-sheaths very densely armed with robust spines, {Leaf-sheaths 
unknown in D. robustus.) 
Leaf-sheaths strongly armed with very robust large and 
unequal laminar spines. Fruit ellipsoid, with yellowish 
green scales, 
32. D. macropterus. 
Leaf-sheaths entirely covered with narrow very long needle- 
like spines, Fruit unknown. 
383. D. Sarasinorum. 
Leaf-sheaths . . . . Fruit spberical with greenish and yellow 
scales, 
34. D. robustus. 
** Leaf-sheaths armed with scattered slender flabby spines. 
Fruit ellipsoid with yellowish green shining scales. 
35. D. lamprolepis. 
Fruit roundish, with reddish brown scales. 
36. D. niger. 
b. Outer spathe in the unopened spadix considerably shorter than the 
inner ones (as in the species of the group of D. Hysiriz), | 
Mouth of the leaf-sheaths quite smooth. Male flowers very 
long and marrow, their calyx elongated, tubular, the corolla 3 
times as long as the calyx. 
: 37. D. Loherianus. 
II. Outer spathe of the unopened spadix considerably shorter than the 
inner ones and terminating in a triangular often bidentate point. (In D. 
Motleyi and D. didymophylius the inner spathes slightly protrude beyond
