an incurved point, one or two, often only one maturiug, attached to 

 base of style, perforation at base oblong triangular.

I have referred this to the above with some doubt ; it has the same 

 prickly hispid habit, but differs in some particulars ; plant growing from 

 fissures in rocks, erect, 1 to \\ feet. Leaves and stems dark green, 

 hispid from hard white "prickle bearing calli, leaves opposite at the 

 divisions of the racemes, otherwise alternate, upper leaves subsessile, 

 lanceolate, acute, prickles longer on the margins and midrib beneath. 

 Racemes lax, the lower ones from opposite axillae upwards, from alter- 

 nate axillae and terminal ; peduncles usually 3-flowered, lengthening with 

 the enlarging calyx in seed : bracteolae none ; calyx rigid, hairy, 5- 

 angled with rounded auriculae, segments acute, corol blue with caudate 

 lobes, stigma simple, blunt, pedicels lengthened with the much in- 

 creased and nutant calyx in seed, acheniae 4, subtrigonal ; the outer 

 faces concave, marginate, the margin acutely serrulate with slightly 

 glochidate teeth. 



My specimens do not exhibit the lower leaves.

59. Salvia ^Egyptica, Linn. : slopes of Hala mountains. 



60. Salvia pumila, Benth : slopes of Hala mountains. 



61. Salvia Halaensis, Vic. : slopes of Hala mountains. Plant of 

 10 — 12 inches, erect, old stems ligneous, younger stems obsoletely 

 4-angled, densely clothed with short hairs, and sessile yellow glands, — 

 leaves much corrugated, cordate -ovate, and broad ovate, blunt or round- 

 ed ; slightly winging the short petioles, and often forming 2 lateral 

 denticulae at their apices ; margins undulate lobate-crenate. Racemes 

 2 — 3 inches long, dense flowered subspicate ; flowers blue, solitary, 

 almost sessile ; floral leaves small, bractea-formed, ovate, entire, hairy 

 and longly ciliate, bracteolae nearly as long as bracts ; linear-lanceolate, 

 hairy ; calyx lanatopilose, enlarging and becoming nutant with the 

 lengthening pedicel ; upper lip shortly tridentate ; the midtooth smaller, 

 all acute, lower lip 2 part with linear filiform lobes. Corol, upper lip 

 erect, short, bifid ; midlobe of lower lip orbicular emarginate. 



The acheniae of this plant give out much mucilage in water.
