6. P. lithospermoides (Lithospermum-like), F. v. 31. Fragm. vi. 107. Benth. 
FI. Austr. v. 101. A shrub of 6 to 8ft., hoary with appressed hairs, the young 
shoots silky. Leaves very shortly petiolate or nearly sessile, oblong-lanceolate or 
almost linear, obtuse or acute, entire, flat or concave, the margins not recurved, 
the larger ones 1 to 2in. long, the floral ones smaller but similar. Flowers 
axillary, on very short pedicels. Bracts nearly as long as the calyx. Calyx 
silky-pubescent, about 24 lines long, the lips nearly equal, entire, or sinuate- 
toothed. Corolla white ( F. v. 31.) or blue ( O' Shanesy ) , softly pubescent, not 
twice as long as the calyx. Anthers with one appendage about twice as long as 
the cell, the other short and adnate. 
Hab.: Table Mount, Rockhampton, 0‘ Shanesy ; Armadilla, TV. Barton ; Mt Perry, J. Keys. 
7. P. nivea (snow-white), A. Cunn. in Benth. Lab. Gen. et. Sp. 452, and in 
DC. Prod. xii. 501 ; Benth. FI. Austr. v. 108. A beautiful shrub of 3 to 6ft., 
glabrous except the corolla or sprinkled with a few appressed hairs, especially on 
the young shoots, and usually of a pale green. Leaves sessile, linear-terete with 
incurved or involute margins, or flat when fresh, acute or obtuse, rather slender, 
mostly 4 to lin. long, the upper floral ones smaller. Flowers rather large, of a 
snow-white or tinged with pale blue, all axillary, the upper ones forming 
interrupted leafy racemes. Pedicels much shorter than the calyx, with short 
setaceous bracts. Calyx 2| to 3 lines long when in flower and not much enlarged 
afterwards, slightly pubescent, the tube prominently ribbed, the lips broad and 
ciliate, the upper one much larger than the lower. Corolla pubescent or villous, 
twice as long as the calyx. Anthers with one appendage about twice as long as 
the cell, the other short and adnate. — Bot. Mag. t. 5658. 
Hab.: Near Stanthorpe. 
8. P. striatiflora (flowers streaked), F. v. 31. in Linnaa, xxv. 425 ; Benth. 
FI. Austr. x. 103. A rigid much branched shrub, sometimes quite low, some- 
times attaining 5 or 6ft., glabrous or the young shoots hoary or silky with short 
appressed hairs, the smaller branches sometimes almost spinescent. Leaves 
sessile or nearly so, oblong-lanceolate or linear, mostly obtuse, entire, flat or 
with incurved margins, rather thick, usually under fin. long, but when narrow 
often fin., the floral ones gradually smaller, the upper ones shorter than the 
calyx. Flowers all axillary, but the upper ones crowded into terminal leafy 
racemes or spikes. Pedicels very short. Calyx-tube not two lines long, 
prominently striate, the upper lip ovate, obtuse, often fin. long when in fruit, 
the lower lip not half so large. Corolla nearly twice as long as the calyx, 
glabrous or sprinkled with a few hairs, white streaked with red and tinged with 
yellow at the base of the broad middle lobe of the lower lip. Anthers with one 
appendage about twice as long as the cell, the other short and adnate. 
Hab.: Newcastle Range, Sutherland ; Stanthorpe. 
The species is very nearly allied to P. nivea, and sometimes difficult to distinguish from it. 
In general it has shorter broader leaves, a more dense inflorescence, the upper lobe of the calyx 
longer and not so broad, and the corolla more glabrous. — Benth. 
9. P. saxicola (growing in stony places), R. Br. Prod. 509 ; Benth. FI. 
Austr. v. 104. A slender shrub or undershrub, sometimes having the appearance 
of a rigid annual ; the stems much branched at the base and ascending to from 
6in. to 1ft. in the typical form, more erect and attaining 2ft. in others, hoary 
with minute appressed hairs or nearly glabrous. Leaves very shortly petiolate 
or nearly sessile, oblong or linear-oblong, obtuse, entire, flat, rather thick, 2 to 4 
lines long in the typical form, the young ones sprinkled with appressed hairs, 
the older ones usually glabrous. Flowers small, in few pairs in the upper axils. 
Pedicels short, with setaceous bracts. Calyx about 2 lines long, more or less 
hispid with spreading hairs especially in the small typical specimens, the lips
