130 QUEENSLAND AGRICULTURAL JOURNAL. [1 Fes., 1898. 
from a broad strongly striate base. Segments or pinne about 30 on each side 
of the rhachis, often distant, 18 to 25 in. long, and sometimes 2 in. broad at the 
centre, folded and attached at the base to the flange-like edge of the rhachis, 
the apex usually long-acuminate or abruptly jagged, and on one side elongating 
into a point which is at times toothed on the inner side and ending in a filiform 
point; terminal segments not confluent, green on both faces. Inflorescence 
below the leaves, 16 to 24 in. long and broad, pendulous; the common 
peduncle 14 to 3 in. long, 1 to 1} in. broad, rather slenderly clasping the stem, 
marked by 2 scars showing the attachment of fallen bracts; rhachis and 
branches thick, flattened, or more or less angular, puberulous, 1 ft. or more of 
the branchlets bearing closely sessile flowers, solitary or 3 at each notch, a 
female with a male on either side. Male perianth-buds oblong, about 8 lines 
long, the outer segments imbricate, orbicular, about 1 line in diameter, margins 
ciliate, inner ones valvate, oblong, exceeding the outer by about 2 lines. 
Stamens 20 or more, about as long as the perianth, filaments shorter than the 
anthers. Anthers versatile, basal lobes somewhat spreading. Female perianth 
much shorter than the males, both series broad, the inner ones somewhat 
apiculate. Fruit not matured on the panicles seen, but the albumen seems to 
be very deeply ruminate. 
Hab. : Somerset, Cape York Peninsula, Frank L Jardine. This plant differs from all other — 
species of Archontophenix and Ptychosperma hitherto met with in Australia; thus I am glad to 
attach to it the name of one who has rendered good service to botanists. 
LIVISTONA, R. Br. 
L. humilis, 2. Br., var. Trunk 7 or 8 ft., clothed to near the base by the 
old leaf-sheaths and portions of the petioles. Leaves very numerous, forming 
a very dense head. Petioles without the sheath about 3} ft. long, and from 
2-in. broad at the base to ¢-in. at upper end, where the upper face forms a rather 
prominent ligula, smooth, edges rather acute, usually bordered in the lower 
half by small curved prickles; leaves of a very harsh texture, nearly orbicular 
in circumference, about 2% ft. long and scarcely as broad, entire for about - 
half the length, then divided into numerous narrow infolded segments, which 
at their extremities are more or less deeply forked, and each fork tapering to 
a thread-like end. The thread-like bristle between the segments at the first 
forking of the leaf short, and here the margins of the segments often minutely 
serrated. Inflorescence, forming elongated panicles, numerous amongst the 
leaves, attaining about 4 ft. in length, upon a peduncle of about 16 in. Bracts 
closely embracing the rhachis, the lower ones exceeding 1 ft. long, the upper 
ones gradually smaller, striate, abruptly acuminate; secondary ones narrower, 
with a prominent finely serrated keel, ending in a longer acumen. Branchlets 
slender, flowers numerous, solitary or in small clusters, but none on the speci- 
mens to hand. Fruit not quite ripe, oval, about 6 lines long, the pericarp thin, 
wrinkled outside. Seed nearly globose, about 38 lines diameter, endocarp pitted. 
Hab. : Cairns, 2. Cowley. 
L. humilis, 2. Br., var. The tree Mr. Jardine had cut down for the 
specimens he forwarded to me stood 47 ft. high, and gave a trunk circumfer- 
ence measurement of 25 in. Leaves (two received) were cut off above the 
sheath. Petioles, the longest over 5 ft, the upper end about 4-in. broad, 
ending on the inner side in a triangular ligula of about 1 in. long, the lower end 
more than twice as broad as the upper; both faces clothed with whitish 
furfuraceous scales, the margins armed in the lower half with strong, short, 
curved, or straight prickles, the upper end of the sheath decurrent on the face 
of the petiole, on both sides within the margin forming long, light-brown, 
woven fibres. Leaf-expansion about 34 ft. long, and not so broad, not so 
orbicular, and of a more membranous texture than other Australian species of 
the,genus ; segments narrow, forking at about 4 or 5.in. from the base, and
