Marianthus.] XII. PITTOSPOEE^. 7B 



ovoid or oblong, turgid or slightly compressed, membranous or slightly coriaceous, 

 the valves sometimes splitting septicidally. Seeds ovoi'd, reniform or globular. — 

 Undershrubs, with procumbent, flexuose, or more frequently twining branches. 

 Leaves entire, toothed, or the lower ones occasionally lobed. Flowers blue, white, 

 and reddish, in terminal compact panicles, usually corymbose or almost umbel- 

 late, rarely solitary or apparently axillary from the extreme shortness of the 

 flowering branch. 



The genus is limited to Australia. It differs from Billardiera solely in the capsular not 

 baccate fruit. The petals are in general more spreading than in Billardiera. — Benth. 



1. Itt, procumbens (procumbent), Benth. Fl. Austr. i. 117. A low, pros- 

 trate or suberect, much-branched shrub, the branches sometimes flexuose and 

 nearly 1ft. long, but usually much shorter, glabrous or slightly pubescent. 

 Leaves crowded and sessile, in the northern varieties usually linear or linear- 

 cuneate, pointed, entire or rarely toothed at the top, 4 to 6 lines long, rigid, with 

 recurved margins ; in the southern forms usually shorter, more cuneate or even 

 obovate or ovate, and often toothed. Flowers small, white or tinged with red, 

 solitary or 2 or 3 together, terminal or appearing axillary from the shortness of 

 the flowering shoots, the pedicels 1 to 2 lines long and always shorter than the 

 leaves at the time of flowering, rather longer and recurved ' when in fruit. 

 Sepals lanceolate-linear, very pointed. Petals about 3 lines long or smaller, 

 spreading from below the middle. Filaments dilated to the middle. Ovules 6 to 

 8 in each cell of the ovary. Style short. Capsule truncate, 8 lines broad and 

 not quite so long. Seeds usually 8 or 4 in each cell, ovoid-reniform, transverse 

 and laterally-attached, deeply wrinkled. — Pittospormn procumbens and P. nanum,

5. CITRIOBATUS, A. Cunn. 



(Derived from local name, " Orangethorn.") 



(Ixiosporum, F. v. M.) 



Petals connivent or connate to above the middle, in a cylindrical tube spreading 

 at the top. Anthers oblong, shorter than the filaments. Ovary 1 -celled, with 2 

 to 6 parietal placentas ; style short. Fruit coriaceous or hard, globular, inde- 

 hiscent. Seeds few or many, nearly globular, often enveloped in a viscous fluid. 

 — Eigid much-branched shrubs, armed with short thorns or abortive branches. 

 Leaves small, entire or toothed. Flowers small, sessile and usually solitary, 

 surrounded by small sepal-like bracts. 



The genus is limited to Australia. 



Leaves cuneate, sessile, 4 to 6 lines long. Placentas 2, with 8 to '10 ovules 



each. Fruit 2 to 5 lines diameter, with few seeds 1. C multiflorus. 



Leaves obovate petiolate, 6 lines long. Placentas 5, with very numerous 



ovules. Fruit lin. diameter or larger, with numerous seeds 2. C. pdudflorue. 



Leaves entire, lanceolate, IJin. long. Fruit 5 lines diameter 3. C. lancifaliibe. 



1. C. multiflorus (flowers numerous), A. Cunn. in Loud. Hort. Brit, (name 

 only) and in. Putterl. Syn. Pittosp. 4 ; Benth. Fl. Austr. i. 121. (" Kary," Eock- 

 hampton, Thozet.) A straggling or prostrate very much branched shrub, with 

 slender branches, rough with a minute pubescence, and bearing numerous subu- 

 late thorns or abortive branches. Leaves sessile, ovate, orbicular, obovate, or 

 broadly cuneate, usually 4 to 6 lines long, entire or with a few small pointed or 

 prickly teeth, rather thin^ green and glabrous on both sides. Flowers about 2
