150 THE TASMANIAN FLORA. 



3-lobed, in most species much exceeding the upper lip). Stamens 4, the 

 connective variously produced. Style shortly bifid. Nuts with a rough surface. 

 The genus, which consists of about 40 shrubs and under-shrubs, is confined to 

 extra-tropical Australian distribution, and is very poorly represented in the 

 west.

Leaves about as broad as long, j-^ inch ... ... 2. P. rotundifolia. 



Leaves obovate, 1-3 lines long... ... ... ... 3. P. cuneata. 



1. P. LASIANTHOS, I/ttb. A tall, erect, branched shrub, mostly from 6-12 feet 

 high. Leaves broadly to narrowly lanceolate, acute, stalked, serrate, pale 

 beneath, mostly 2-3 inches loug. Flowers usually many, in terminal compound 

 racemes. Flower-stalk 2-3 lines, bearing 2, usually linear, bracts, about 1 line 

 long. Calyx about 2 lines long, the lips broad, rounded, about as long as the 

 tube. Corolla white, marked with purple, |-| inch long, pubescent throughout. 



Very common ; also throughout extra-tropical Australia. Fl. Dec. 



2. P. ROTUNDIFOLIA, B. Br. A tall, branched, spreading shrub, often 6-7 feet 

 high. Leaves broadly reniform, orbicular or even spathulate, entire, mostly 

 from 2-6 lines long, on stalks mostly as long as the laminse. Flowers in small 

 terminal racemes. Flower-stalks 1-2 lines, bearing 2 linear deciduous bracts. 

 Calyx about 2 lines long ; lips short and very broad. Corolla blue, nearly j inch 

 long. 



Common in the vicinity of the North and South Esk, East Coast ; also in 

 New South Wales, Victoria, and South Australia. Fl. Sept. 



3. P. CUNEATA, Benih. A branched spreading shrub, of 2-3 feet. Leaves 

 sessile or nearly so, narrow-obovate to orbicular, obtuse, contracted below, but 

 seldom stalked, often recurved towards the point, and concave from side to side, 

 mostly 1-3 lines long, usually clustered on the branches. Flowers mostly 

 solitary, axillary, towards the ends of the branches, but sometimes in sufficient 

 number to make the termination of the branch to appear as a leafy raceme. 

 Flower-stalk about 1 line long. Bracts rather long, linear. Calyx nearly 3 lines 

 long, the tube conspicuously striate ; the lips broadly rounded, about as long as 

 the tube. Corolla white, spotted with purple, about | inch long, hardly or not 

 at all pubescent. 



South Esk River ; also in the Australian Alps, Victoria. Fl. Nov.

8. WESTRINGIA. 



Calyx 5-toothed or lobed. Corolla-tube shoi't ; lobes 2-lipped (upper lip 

 erect, but flat and broadly 2-lobed ; the lower lip spreading and 3-lobed). 

 Stamens 2 perfect ones and 2 more or less rudimentary. Style shortly bifid. 

 Nuts with a rough surface. 



A purely Australian genus. The species are notoriously variable, and 

 connected by intermediate links. 



Leaves linear. Calyx- teeth very short ... ... 1. W. rigida. 



Leaves oblong. Calyx-teeth long. 



Leaves with revolute margins, hairy beneath ... 2. W.brevifolia. 



Leaves flat, glabrous or nearly so . . . ... ... 3. TF. ruhicefolia. 



1. W. RIGIDA, B. Br. A rigid, somewhat spreading, shrub, mostly 5-6 feet 

 high, more or less pubescent in most parts. Leaves in whorls of 3 or 4, linear, 

 acute, often rigid, margins closely revolute, upper surface usually roughly 

 tuberculate, under surface white with hairs, mostly ^-| inch long. Flowers 

 sessile, solitary, axillary, few or many towards the ends of the branches. 

 Calyx -tube about 3 lines long, ribbed; teeth very short and acute. Corolla
