356 QUEENSLAND AGRICULTURAL JOURNAL. [1 Nov., 1898. 
N. Alice (n. sp.) Plate LX. (After Miss Alice Jardine, an enthusiastic col- 
lector of Cape York Peninsula plants). A dwarf plant, forming pitchers when 
only 3 or 4 in. high, not exceeding a height of more than a foot (Ff. L. Jardine), 
starting from a creeping rhizome. Leaves numerous, sessile, and stem- 
clasping at the base, lamina or broad portion lanceolate, falcate, conduplicate, 
2 to 33 in. long, $ to $ in. broad when opened out; parallel nerves 3 or 4 
on each side of costa, the naked portion or pitcher stalk slender, about 2 to 
3 in.long. Pitchers 14 to 23 in. long, 3 to # in. diameter, slightly enlarging 
above the base, and again at the orifice, anterior ribs with entire wings about 
a-line broad, parallel longitudinal nerves numerous; and as well as the reticula- 
tions rather prominent; peristome narrow, posterior spur recurved, often 
flattened and rather long. Operculum orbicular, 8 lines diameter, purple and 
glandular. Flowers and fruits unknown. 
_ Hab. : Cape York Peninsula, ¥. L. Jardine. Some effort should be made to introduce this 
unique species into cultivation. 
Order CYCADACEZ, 
MACROZAMTA, Mig. 
M. platyrhachis (n. sp.) Seems not to form stems above the ground; the 
underground stem oval, resembling a somewhat large Swede turnip, about 1 ft. 
-long with a circumference of 2 ft. near the centre, smoothly imbricated by 
the thin bases of former leaves. Leaves probably about 12 in the crown, 
glabrous or when young very thinly pulverulent, falcate, about 3 ft. long of 
which the petiole occupies about 6 or 8 in.; no woolly substance at their base. 
Petiole and rhachis flat on the upper, conyexed on the underside, the broadest 
part about 6 lines, Pinnw or segments attached along the thin edge of the 
rhachis, and slightly decurrent without any callosity, about 28 on each side of 
thachis, the lowest ones often the longer, measuring about 15 in. long and 
a4-in. wide, very coriaceous, curved, erect; longitudinal nerves numerous and 
prominent; apex obtusely acuminate. Scapes 3 on the only plant (male) to 
hand, 6 to 9 in. high, bearing cylindrical cones 8 or 4 in. long, scales of the 
upper portion bearing fine erect central spines. According to Mr. Brock- 
Hollinshead, the female cones seldom exceed a foot in length, and closely 
resemble those of M. Miguelii, F.v.M. Two dry nuts received with the plant 
are oblong, bluntly angular, and about 18 lines long. 
Hab. : Planet Downs, H. C. Brock-Hollinshead, who informs me that this species does not 
cause rickets in stock. 
PLANTS REPUTED POISONOUS TO STOCK. 
By F. MANSON BAILEY, F.1.S., 
Colonial Botanist. 
NOOGOORA BURR (XANTHIUM STRUMARIUM, Linn.). 
Aw annual belonging to the order Composite, often attaining a height of 
8 to 10 feet, with wide spreading branches. The stems, especially in a young 
_ State, are mottled with purple. The leaves, which are from 2 to Ginches broad, 
muchresemble those of a mallow. The maleand female flowers are separate, but 
on the same plant, the upper ones being the male and the lower ones the female. 
The burrsaremuch larger, and thehooked prickles with which they are clothed are 
coarser, than those of the Bathurst burr (Xanthium spinosum). See Plate UXT. 
The plant, which is known also as the “Small Burdock’? and “ Cockle Burr,” 
was introduced into the colony about nineteen years ago, at Noogoora Estate, 
near Ipswich. At that time Mr. P. R. Gordon, Chief Inspector of Stock, 
forwarded specimens to me which had been received from the above locality. 
In identifying the plant I remarked that if not eradicated it would become a 
great pest, and he published this warning, but as no notice was taken of this 
we now find the Southern part of our colony overrun with the pest. Year after
