CASUARlNEiE. 
Casuarma horrida , sp. nov. 
A shrub of about nine feet in height with numerous erect, rigid 
branclilets. Whorls mostly 10 — 12 merous, the teeth short, dark, the 
internodes obscurely striate. Male amenta not seen. Cones rather 
small, depressed, globular, half an inch in diameter. Bracts villous 
on the outside, very short, less than one line long, broad, cuneate, 
mucronate, about half as long as the valves. Valves nearly two lines 
long, villous except the upper third, which is dark, the dorsal pro- 
tuberance attached about one-third of the way from the base, 
villous, the broad part shorter than the valve, produced into a fine 
curved glabrous spine of two lines which gives the cone a bristly 
appearance. Achene brownish-black, produced at the apex into an 
oblique membranous wing. 
Locality: Merredin, on sand plain. Also observed, but not 
collected, at Westonia, in similar country. 
Collectors: Herbert & Wilson, No. 99. 
Date: November, 1920. 
Following the arrangement adopted in Bent ham’s Flora Aus- 
Iraliensis , this species falls into the section Acanthopitys, and has its 
closest relatives in C. thuy aides , Mig., on the one hand and in C. 
bicuspidata , Henth., on the other. It resembles the former in the 
number of teeth in the whorls, and the latter in the cones, the points 
of the dorsal protuberances, however, being much finer. Male 
spikes are necessary to complete the description. The name is in 
allusion to the bristly appearance of the cones. The type is in the 
W T estern Australian Government Herbarium, specimens collected at 
the same time being in the Arnold Arboretum at the Harvard 
U niversitv .
