PROSTANTHERA AND ITS ESSENTIAL OIL. 105 



Systematic Botany. 

 Prostanthera cineolifera, sp. nov. 

 A leafy shrub, several feet in height, stems and branchlets 

 hoary pubescent, foliage glabrous. Leaves, mostly about 

 an inch long but in a few cases two inches, lanceolate, 

 entire, flat, pale and punctate on the under side, dark green 

 above with a few white scales, up to half an inch broad. 

 Flowers in terminal racemes, distant, opposite in slender 

 pedicels, about two inches long. Pedicels longer than the 

 calyx with minute bracts removed from the calyx. Calyx 

 under two lines long, tube striate, the lower lip longer than 

 the upper, glabrous with a few white scales. Corolla slightly 

 pubescent on the inside, but glabrous internally, twice the 

 length of the calyx, the upper lobes rather shorter and 

 smaller than the lateral ones, all acuminate, the lower lip 

 twice the size of the lateral and lobed, with edges slightly 

 crenate. Anther without appendages or very minute.

Remarks. — This species belongs to the racemosse group 

 of Prostanthera, a section of the genus established by 

 Bentham in his Flora of Australia, Vol. v, p. 91, and of the 

 species so recorded this one appears to be quite distinct in 

 foliage, inflorescence and other characters. 



Bentham divides this section into groups according to 

 the size of the leaf i.e., those mostly above one inch, and
