PLANTS INDIGENOUS TO 
[Pittosporece. 
solitary one similar to tJie bracts at the middle of the pedicel. Sepals l^—2 lines long*, narrow- or linear- 
lanceolate, acuminate. Corolla straight, §-l inch long, inside glabrous, outside green-yellow towards the 
base, almost orange-colored towards the middle, yellowish at the apex and throughout inside, consisting of 
narrow-cuneate petals, which are finely striate-veined, produce a roundish or blunt triangular free lamina of 
only l±-2 lines length, and are early separated at their base. Filaments setaceous, glabrous, as long as the 
coherent part of the corolla. Anthers oscillating, about § line long. Style about as long as the stamens, 
setaceous, scantily downy towards the base. Stigma slightly dilated and distinctly bilobed. Ovary silky, 
showing at the base five minute glands. Capsule generally less than 1 inch long, only i-2 lines broad. 
Valves of a thinner texture than in most congeners, separating to near the base, seemingly not cleft, 
appressed-downy. Seeds brown, about 1 line long.

This species holds, as regards its almost tubular corolla, the same position to its congeners as Billar¬ 
diera' longiflora to the other Billardiera. 
In flower throughout the whole year, although more copiously during the spring. 
BILLARDIERA. 
Smith , Botany of New Holland , i. 1. 
Sepals free. Petals move or less coherent into a tube, unguiculate. Filaments elongate, sur¬ 
rounding the pistil. Anthers free, bursting longitudinally. Style filiform or setaceous. Stigma minute, 
bilobed. Berry pulpous or hollow , one- or two-celled. Seed several or many in each cell, turgid or 
compressed, wingless. 
Handsome suffruticose or shrubby climbing plants, extending through the greater part of extra- 
tropical Australia. Leaves alternate, herbaceous or subcoriaceous, entire, sometimes partially toothed, 
never extremely narrow. Flowers generally terminal, solitary 7 -, fasciculate or cymose. Petals yellowish 
or more or less violet or purplish. — Gaud. Prodr. i. 345 ; Putt. Syn. Pittosp. 27 ; ^Pronaya, Hueg. Bot.

In this genus we find the flowers of Marianthus combined with the fruit of Sollya. All those 
species of Billardiera, not indigenous to Victoria, were formerly regarded as belonging to a distinct 
genus, viz., Pronaya. They comprise B. elegans (Pronaya elegans, Hueg. Bot. Archiv. 6; Campylanthera 
Frazeri, Hook. Icon. i. 82); B. Huegeliana (Pronaya Huegeliana, Putt, in Lehm. PI. Preiss. i. 204) ; 
B. speciosa (Pronaya speciosa, Endl. in Enum. PI. Hueg. 9) ; and B. Lehmanniana (Marianthus angus- 
tifolius, Putt, in Lehm. PI. Preiss. i. 200 ; Pronaya angustifolia, Lehm. Index Sem. Hort. Hamb. 1845, 
PI. Preiss. ii. 233).
