OF THE INTERIOR OF WESTERN AUSTRALIA. 179 
MALvVACE. 
LAVATERA PLEBEIA, Sims. Between Uladdie soak and Yil- 
gangie claypans, March. Near Coolgardie, August. 
The Coolgardie specimens are remarkably small, ouly 10-12 em. 
high, and proportionately diminished all round. 
MALVA PARVIFLORA, Linn. Bullabulling, September. An 
undoubted introduction. 
PLAGIANTHUS REPENS, sp. nov. Suffruticosa, repens, pubes- 
cens, foliis parvis longipetiolatis rotundato-ovatis vel suborbi- 
cularibus rarius ovatis plerisque inzqualiter 5-lobulatis, floribus 
parvis axillaribus solitariis vel breviter racemosis subsessilibus 
hermapbroditis, calyce tubuloso 5-lobato, petalis calycem sub- 
sequantibus vel paullo excedentibus, staminibus 10, ovarii loculis 
5, stylis filiformibus stamina superantibus. 
Hab. Crescit juxta Gibraltar, mens. Oct. florens et fructificans. 
Caules sat validi, crebro ramosi, subtus demum puberuli. 
Foliorum lamina 0:5-1:0 cm. long. et lat., basi truncata vel 
obtusa; lobi circa 0:15 em. long., deltoidei, obtusi; petioli usque 
ad 0:8 em. long., plerumque vero breviores; stipulæ lineares, 0:25 
em. long. Calyx 0'45 em. long., circa 0:5 em. diam., 5-angulatus ; 
lobi ejus deltoidei, obtusi. Petala late oblonga, obtusissima. 
Ovarium glabrum. Styli elongati, deorsum geniculati. Car- 
pela matura 5, calyce inclusa, puberula, apice subito elevata 
ibique obtusa. Semina atra, scrobiculata, 0°13 em. long. 
This is evidently closely allied to P. diffusus, Benth. The chief 
points of difference are the indumentum, the subsessile herma- 
phrodite flowers, and the invariable decandry. 
SIDA PrrROPHILA, F. Muell. Wilson's patch between Mount 
Margaret and Lake Darlót, May. Plain south of Doyle's well, 
June. A small subshrub, 2-3 feet high. Flowers yellow. 
S. sp. indet. Near Ccolgardie, August. A small yellow- 
flowered subshrub. 
The specimens, which are in early flower, have the general 
appearauce of S. calyxhymenia, J. Gay, the calyx of which is 
strongly accrescent, whereas that of S. petrophila, F. Muell., 
which the present plant also resembles, is scarcely so at all. 
For this reason I am unable to definitely name the specimens.
