 IV. 135. A glabrous perennial, flowering the first year so as to appear annual, 

 but formmg at length a hard rootstock, erect, with few, spreading branches, 

 i to 1ft. high. Leaves linear, irregularly pinnatifid, often 2 to 3in. long, the 

 lobes linear or linear-lanceolate. Pedicels axillary, 2 to 6in. long. Flowers 

 large, of a bluish -purple, very pale or with a yellowish-green tint outside. Calyx- 

 lobes linear, rigid, as long as the oblong tube. Corolla-tube f to lin. long, 

 somewhat incurved and broarder upwards ; lobes spreading to a diameter of f to 

 lin., narrow, mucronate, slightly unequal, and not quite so flat as in /. Brownii. 

 Anthers glabrous, the 2 lower ones with single, rigid bristles. Capsule 

 cylindrical, tapering and slightly oblique at the base, 6 to 8 lines long, 2 to 3 lines 

 broad. Seeds small, very minutely foveolate. — Gaudioh. in. Freyc. Voy. 455 t.

2. I. petraea (on rocks), B.v. M. in Linnaa, xxv. 420; Benth. Fl. Austr. 

 IV. 135. Very closely allied to I. axillaris, and Bentham would have proposed 

 reducing it to a variety of that species but that, among numerous specimens from 

 various localities, he saw no intermediates. Habit, stature, inflorescence, flowers, 

 and fruit the same, but the leaves are all ovate-oblong or eliptical, bordered by 

 irregular linear or lanceolate teeth or lobes, but never longer than the breadth of 

 the entire central part.

3. I. GuUiverii (after Thos. Gulliver), F. v. M. Fragvi. x. 39. A small 

 weak annual of a few inches. Leaves from 2 to 12 lines long, linear-lanceolate, 

 toothed or entire, somewhat pilose, scattered. Pedicels 1 to 2in. long, capillary 

 solitary. Flowers bisexual. Calyx somewhat pilose, lobes scarcely 1 line long, 

 subulate-lanceolate. Corolla tube almost 4 lines long, slender, lobes bluish. 

 Anthers 1 line or less, the back of the upper ones slightly puberulent, lower ones 

 shortly bearded at the apex, bristles very minute. Capsule ovate; about 2 lines 

 long. Seeds pale, very minute, compressed, smooth.

4. I. fluviatiliS (near rivers), F. v. M. Herb.; Benth. Fl. Austr. iv. 136. 

 A small, prostrate or creeping perennial, jjsually pubescent, with the habit of 

 some species of Pratia. Leaves in a typical form oblong or almost linear, or the 

 lower ones ovate or obovate, mostly 3 to" 4 lines long, slightly toothed, shortly 

 petiolate or the upper ones sessile. Flowers on axillary pedicels, varying from 

 the length of the leaves to twice as long. Calyx-tube narrow, turbinate, 

 pubescent ; lobes short, lanceolate. Corolla usually 5 to 6 lines long, but sometimes 

 much smaller, the entire tube longer than the calyx-lobes ; the lobes oblong, 

 almost acute, nearly equal but oblique, and the 2 upper separated rather lower 

 down. Anthers glabrous, the 2 lower ones tipped each with one rigid broad 

 bristle and several smaller ones. Capsule about 2 lines long. Seeds ovoid, 

 smooth.— Lobelia fluviatilis, E. Br. Prod. 563; A. DC. Prod. vii. 366. 



Hab.: Southern localities.
