D. petiolaris. | BECCARI. THE SPECIES OF DAEMONOROPS. e 91 
pubescence, rather suddenly narrowing into a beak which is only a third or 
fourth part of its entire length, rather densely armed with long, rigid, very 
narrowly laminar or acicular, brown-spadiceous or blackish, usually straight, solitary or 
slightly confluent, spreading or deflexed spines,; the second and third spathes 
spinous only near the apex, slightly shorter than the first; the others unarmed. 
Male spadiz (when not enveloped by the spathes) densely panicled-thyrsoid ; partial 
inflorescences densely thyrsoid-cupressiform, decompound, or with many secondary 
branchlets; the latter 3-4 cm. long, each bearing 4-5 spikelets on each side; spike- 
lets short, 10-18 mm. long with 2-4 flowers on each side; their axis sinuous, 
ferrugineous-pubescent ; spathels bracteiform, small, acute; involucre distinctly callous 
at its axilla, deeply cupular, the third part the length of the calyx, truncate and 
usually distinctly 2-denticulate. Male flowers oblong, obtuse, 5:5 mm. long, 15 
mm. broad, rusty-furfuraceous; the calyx tubular-campanulate, rather Strongly stri- 
ately-veined externally, distinctly 3-toothed, its margin ciliate-furfuraceous, especially 
on the apex of the teeth; the corolla twice as long as the calyx, divided down 
for two-thirds of its length into three narrow, rather acute, externally  striolate 
segments; stamens with filaments united halfway up the corolla; rudimentary ovary 
very small, Female spadiz . . . .

OBSERVATIONS.— Griffith has distinguished two forms of C. petiolaris, but probably 
considering the great variability in the individuals of Daemonorops of the group of 
Cymbospathae, and the extraordinary differences in the leaves of this species, depend- 
ing on their different situations, at the base of the stem, along it or at its 
apex, probably there are not sufficient reasons for keeping the two forms distinct. 
I have seen portions of Griffith’s authentic specimens of both, but in those of 
var. a at Kew the petiole is wanting. The specimens of var. 8 have a portion 
of the petiole, which is terete and 6-8 mm. in diam.; it is described by Griffith 
as wholly unarmed in its upper portion, while in var. a it is said to be priekly at 
the margins and clawed beneath. I suppose, however, that really the radical leaves 
have a very long terete petiole, in its upper part quite smooth, and that the 
leaves of the lower part of the stem, forming the passage to those of the apex 
though also provided with a long petiole, have this more armed than the radical 
ones, In the spadix, spathes and flowers of the two varieties I have observed only 
very] trifling differences. 
D. petiolaris is certainly related to D. calicarpus, but it seems to me sufficiently 
distinguished by its leaf-sheaths armed with scattered, non-confluent, and not seriate 
spines, and by the outer spathes being much less covered with spines, and these 
of the usual kind, not bristly. .
