1. P. lasianthos (flowers woolly), Labill. PL Xov. Holl. ii. 18, t. 157; 
Benth. FI. Austr. v. 93. A tall shrub, sometimes attaining the dimensions of a 
moderate-sized tree, glabrous except the flowers. Leaves petiolate, usually 
oblong-lanceolate, rather acute, serrate, flat or the margins recurved, of a firm 
consistence, not rugose, dark green above, pale or glaucous and minutely dotted 
underneath, 2 to 3in. long ; in some specimens shorter broader more 
entire and almost coriaceous. Flowers opposite in pairs, in short leafless 
racemes, forming a terminal panicle often leafy at the base, but the leaves under 
the upper racemes very much reduced and those under the pairs of flowers 
entirely abortive. Pedicels short. Bracts linear, shorter than the calyx and 
sometimes very minute. Calyx slightly pubescent, attaining 3 lines when in 
fruit, the tube obscurely striate, the upper lip broad, the lower rather smaller. 
Corolla white tinged or spotted with pink or pale blue, hairy inside and out, often 
-jin. long, the lobes very broad. Anthers with the longer appendage about twice 
as long as the cell, the other short and adnate. — Br. Prod. SOS ; Benth. in DC.

thick and flat, rarely exceeding lin. and mostly smaller. Flowers rather small, 
in short loose terminal racemes, the floral leaves small, bract-like and deciduous, 
or the lower pair more leaf-like. Calyx not above 2 lines long, the lips nearly 
equal and both entire. Corolla purple, about 4 or 5 lines long, slightly pubescent
