The leaves in this plant have dried a greenish-brown colour, about the 
same on both surfaces; the petioles are 1-2 em. long and the largest leaf is 
2 dm. in length (excluding the acumen, which is broken off), and 5 em. 
across ; the next largest is 1°6 dm. long (including acumen 2 cm, in length), 
and 8 em. broad ; the stipules are lanceolate acute, with dilated bases, mem- 
branous, +2 em. long. The d cymes are axillary, solitary or binate, long- 
peduneulate, with a setose rhachis, the whole inflorescence varving very 
much in length, from 2-8-12 em. long, when well developed. The 4 flowers 
are 5-partite and 5-staminate, 3 mm. across, shortly pedicellate, the perianth- 
lobes round and membranous, with brown veinings. 
This species is nearest to P. Griffithiana, Wedd. (ex deser.), but differs in 
the long-petiolate and larger leaves, larger stipules, and the long-peduncled 
d inflorescence.

The plant shows a creeping rhizome, with single unbranched aerial shoots, 
2:5 dm. (no. 4013) to 1 dm. high (no. 4283). The shoots of the latter 
specimen are altogether smaller and more delicate in texture. The stipules 
are lanceolate, membranous, glabrous, 6 mm. long and 2 mm. broad. The 
d cymes are axillary, shortly pedunculate, 6 mm. broad and 3 mm. in 
height, the involucre consisting of three bracts, two large ones with
