1. !•. lilacina (flowers lilac), F. r. M.; Benth. Fl. Austr. iv. 821. A slender 

 twiner, the branches almost filiform, pubescent as well as the inflorescence and 

 often the nerves of the leaves underneath, the foliage otherwise glabrous. 

 Leaves on very short petioles, oval-oblong or lanceolate, usually mucronate, 

 cordate at the base, membranous, the margins often undulate or crisped, 1 to 

 l^in. long. Flowers few, in loose terminal almost filiform cymes. Pedicels 

 mostly longer than the calyx. Calyx-segments lanceolate, acute, about | line 

 long. Corolla glabrous inside, the tube above 1 line long, the lobes acute, as 

 long as the tube, valvate in the bud. Anthers united in a half-exserted cone. 

 Hypogynous scales lanceolate, as long as the ovary. Fruit separating into 

 membranous follicles of 3 or 4in., with a placenta in each. — Parsonsia lilacina, 

 F. v. M. Fragm. vi. 127. 



Hab.: Eookhampton, Dallachy ; Scrubby Creek, Leichhardt. 



2. I., straminea (straw-coloured), R. Br. Prod. 466; Benth. Fl. Austr. 

 iv. 321. ^ A woody climber, scaUng trees to a great height, the pendulous 

 branches rooting when they reach the ground. Leaves shortly petiolate, ovate- 

 lanceolate or lanceolate, often acuminate, glabrous, smooth and shining above, 

 paler underneath, the primary veins oblique and usually prominent underneath, 

 2 to 3 or sometimes 4in. long, in loose pedunculate trichotomous cymes or 

 panicles, terminal on the young shoots or axillary on the older ones, minutely 

 pubescent. Calyx-segments narrow, acute, about f line long. Corolla-tube 

 about as long as the calyx ; lobes lanceolate, acute, about twice as long as the 

 tube, bearded inside at the base with reflexed hairs. Stamens inserted at the 

 base of the corolla-tube ; anthers linear, connivent in an exserted cone or 

 cylinder, the basal lobes long and linear. Hypogynous scales large, obtuse. 

 Ovary pubescent. Fruit 2 to 3in. long, tardily dividing into rather thin follicles, 

 the 2 placentas closely connate by the backs and separating from the follicles 

 in a single plate. — A. DC. Prod. viii. 401 (partly) ; Hook. f. Fl. Tasm. i. 270 ;

3. Ii. reticulata (leaves netted-veined), F. v. 31. llep. Burdek. Exped. 16 ; 

 Benth, Fl. Austr. iv. 321. An immense woody climber. Leaves petiolate, 

 oblong-elliptical or broadly lanceolate, obtuse acute or acuminate, shining 

 above and pale underneath as in L. straminea, but much more prominently 

 veined and reticulate, and usually 8 to 4in. long. Flowers in terminal corymbose 

 pedunculate cymes or panicles, minutely pubescent as in L, straminea. 

 Calyx-segments nearly 1 line long. Corolla about 3 lines long, the lobes scarcely 

 longer than the tube, bearded inside almost to the end. Stamens inserted higher 

 up the tube than in L. straminea ; anthers united in an exserted cone or cylinder. 

 Hypogynous scales united in a 5-lobed cup. Fruit hard, 6 to Sin. long, tardily 

 separating into 2 follicles, each one (in some fruits at least) carrying off its own 

 pkicenta. 



Hab.: Keppel Bay, R. Brown; Moreton Bay and Port Deniaon, Fitzalan ; Eookhampton, 

 Dallachy ; common on open country throughout the colony. 



4. Ii. Iiangiana (after Thomas Lang), F. v. M. Fragm. vi. 128 ; Benth. Fl. 

 Austr. iv. 322. A very tall woody climber, the branches, under side of the 

 leaves, and inflorescence rusty-pubescent. Leaves shortly petiolate, ovate or 

 ovate-lanceolate, acuminate, rounded or somewhat cordate at the iDase, shining 

 and sprinkled with a few hairs on the upper side, penniveined with transverse 

 reticulations usually conspicuous on the upper surface, mostly 3 to 4in. long. 

 Flowers small, yellow, pubescent, in very loose divaricately-branched cymes, 

 oh axillary peduncles often as long as the leaves. Pedicels rather thick, 1 to 2 

 lines long. Calyx-segments broad, about ^ line long. Corolla-tube broad,
