2. Dierastylis reticulata, J. Drum. ; erecta, tomento stellato-ramoso al- 
bido vel fulvescente, foliis viridibus ovato-oblongis crenulatis subtus 
reticulatis, panicula subcapitata. 
Has. Northern districts (n. 94). 
3. Dierastylis Stechas, J. Dr.; diffusa, tomento lanoso niveo, foliis li- 
nearibus margine revolutis crenulatis lanatis subtus demum nudius- 
culis, glomerulis ramos foliosos terminantibus. 
Has. Northern districts (n. 95). 
HÆMODORACEÆ. 
12. MacrorIDIA, J. Drum. (Kangaroo’s foot, Col.)—GEN. CHAR. Pe- 
rigonium corollinum, lanatum, tubo basi cum ovario connato elon- 
gato ore obliquo (tandem deciduum ?) ; limbi sexfidi laciniis patenti- 
bus adscendentibus. Stamina 6, fauci perigonii inserta, exserta ; 
filamenta adscendentia ; antheræ adnatæ, longitudinaliter dehiscentes. 
Ovarium triloculare; ovula in loculis solitaria / peltata. Columna 
maxima, triloba. Stylus filiformis. Capsula loculicido-trivalvis.— 
Herba perennis, habitu omnino Anigosanthi; differt tamen ovulis so- 
litariis. 
Maeropidia fumosa, J. Drum. 
Has. Northern districts. 
LiLIACE. 
XANTHORRHEA Drummondii, Harv.; trunco elato simplici, foliis rec- 
tangule tetragonis, amento cylindrico longissimo (4—8-pedali), brac- 
teis fasciculorum flore subbrevioribus apice barbatis, perigonii foliolis 
imberbibus. 
Has. On dry hills, near Perth and elsewhere.— This is the largest 
aud finest of the genus, and produces the most valuable gum. It is 
readily known from the common Black-boy (X. Preissii ?) by the square, 
instead of rhomboidal section of its leaves, which are of a bluish-green : 
colour and far less brittle. e
