(1925) ; and 40 : 57-61 (1928). The genus is restricted 
to Australia and about 100 species are known from Tas- 
mania and the southern and eastern parts of the main- 
land and adjacent islands. They are mostly small to 
medium sized, twiggy, erect or rarely depressed or 
prostrate shrubs with predominantly yellow flowers often 
marked with red near the claw of the standard and with 
orange, red or dark purple on the keel. Only about 18 
species are known from Queensland, chiefly from sandy 
and sometimes swampy places or from rocky hillsides. 
They are usually known as “bush peas.” P. myrtoides 
and the varieties of P. paleacea are common plants of 
the wetter parts of the wallum country and occur in 
other swampy, sandy places; P. villom is a rather widely 
spread species in »S.E. Queensland on drier ground; 
P. euchila is a showy but less common species of dry, 
stony hillsides; and P. r si'll s a is fairly widely distributed 
from swampy wallum country to rather dry hillsides; 
very little is known of some species. 
P. whiteana is well distinguished by the following 
combination of characters : branches covered with long 
stipules with recurving points; densely arranged, alter- 
nate, long and narrow, concave leaves with incurving 
sides; dense heads of large, brilliantly yellow flowers 
Avith orange on the keel; inconspicuous bracts glabrous 
except for the shortly hairy keels; bracteoles free from 
tin; cal \ x, bifid and stipule-like with a small, subulate, 
hairy, green blade near the middle; hairy calyx, 2-lipped' 
to the middle, with more or less triangular and more or 
less acute (but not acuminate) lobes; and sessile, hairy 
ovary. In general appearance, P. whiteana closely re- 
sembles P. stipularis Km. from the neighbourhood of 
Sydney, but this has less concave, more pointed, more 
or less 3-nerved leaves, longer pedicels, longer bracts, 
linear-acute herbaceous bracteoles adnate to (inserted 
on) the calyx-tube, and less hairy calyx with longer, A'ery 
narrow and A’ery acute lobes. Among the species with 
capitate flowers and more or less stipule-like bracteoles 
free from the calyx, P. whiteana most closely resembles 
P. plumosa Sieb. ex DC. (from the neighbourhood of 
Sydney), but this has smaller, broader, much more hairy 
leaves, relatively longer bracteoles with a smaller stipule- 
like base, and smaller flowers with relatively longer, nar- 
roAver, subulate-acuminate calyx-lobes.
