370 NOTES FROM THE BOTANIC GARDENS, NO. XL, 



revolute, leaving frequently the under side exposed only on the 

 broad base, the upper side almost glabrous on some of the old 

 stem-leaves. Flowers almost sessile in the axils of the upper 

 leaves, forming interrupted leafy spike-like racemes, generally 

 with a tuft of empty leaves at the top. Calyx about 2 lines long, 

 the lips nearly equal in length and breadth and nearly equally 

 pubescent, with a pair of pubescent linear bracts close at the 

 base. Corolla lavender-coloured, hardly twice as long as the 

 calyx, the only glabrous part of the plant. Anthers with hardly 

 a conspicuous free appendage. Fruits not seen. 



In affinity it comes nearest P. rhonihea R.Br., but is markedly 

 distinguished from it in foliage and indumentum. The typical 

 P. rhombea is a rather sparse-leaved plant with glabrous rhomboid 

 leaves on which the resinous glands can be distinctly seen as 

 little brown sparkling dots, while in our new species no glands 

 are visible on any part of the plant, and the shape and consistence 

 of the leaves and calyces are very different. 



It seems to be a very local plant; as far as is known at present, 

 it is confined to the fissures of rocks on the top of a granite ridge 

 overlooking the township of Howell, 19 miles south of Inverell.

Atherton, North Queensland (E. Betche; Aug. '01). 



An erect, glabrous, almost herbaceous shrub, about 4 to 6 feet 

 high, with a slender straight stem, and almost horizontally 

 spreading, slender, straight, green, slightly flattened branches. 

 Leaves shortly petiolate, alternate, distichously arranged, ovate- 

 lanceolate, generally 3 to 4 inches long and 1 J to nearly 2 inches 

 broad in the broadest part near the base, dark green and shining 

 above, rather paler underneath. Stipules persistent, above 1^ 

 lines long, tapering from a broad base to a point, with scarious 

 edges. Flowers in axillary clusters, generally 2 to 5 together, 

 the males minute and on pedicels not exceeding 2 or 3 lines, the 

 females much larger and on stouter pedicels lengthening out to 

 1 J inches in fruit, both sexes usually in the same cluster. Calyx-
