THE TASMANIAN FLORA. 107 



A small genus, only differing from Lobelia in the entire corolla- tube and the 

 stamens being inserted into the summit of the tube instead of at its base. The 

 distinction is of doubtful value, and is not maintained in Hook. "PL Tas." 



I. FLDVlATlLis, F. V. M. A prostrate creeping perennial, usually somewhat 

 pubescent, and much resembling some forms of Lobelia pedunculafa. Leaves 

 ovate to almost linear, sessile or shortly stalked, obscurely toothed, 3-6 lines 

 long. Flowers solitary, axillary, on more or less elongated stalks. Calyx-lobes 

 short, lanceolate. Corolla usually 4-6 lines long, blue and white, tube much 

 exceeding the calyx. Lobes oblique, nearly equal, about as long as the tube, 

 narrow-oblong. Seeds ovoid, smooth. Lobelia Jhiviatilii, Hook. 



Various parts in the north ; Clydevale, near Campbell Town, Jordan River ; 

 also in New South Wales, Victoria, South Australia, and Queensland. Fl. 

 Dec-Jan. 



3. WAHLENBERGIA. 



Calyx normally 5 or 4-lobed. Corolla regular, campamilate, tubular at the 

 base, lobed above. Stamens free. Ovary usually 3-5-celled, rarely 2-celled. 

 Fruit capsular, opening by terminal slits. 



A large genus, of wide distribution, principally developed in South Africa. 

 The Australian region possesses but two species — one confined to a very 

 constricted distribution in Tasmania and New Zealand ; the other is common to 

 the East Indies and tropical .Asia, besides Australia and New Zealand.

1. W. GEACILIS, D. C. Extremely variable in size and habit, pubescent or 

 glabrous. The whole plant sometimes not 2 inches high (with a flower about 

 1 line long) to much elongated, erect or decumbent, l|-2 feet long, with 

 flowers exceeding 1 inch. Leaves obovate to linear, obscurely dentate in fairly- 

 grown plants, usually ^-1 inch long. Flowers solitary, on long terminal stalks. 

 Corolla blue, or rarely white, broadly campanulate. Ovary normally 3-celled. 



Very common. Common also throughout Australia. Fl. spring and summer. 



2. W. SAXICOLA, D. C. A tufted or creeping perennial, rarely with short leafy 

 branches. Leaves in a rosette at the base of the stem or crowded on the short 

 branches, obovate to linear, \-\ inch long. Flower solitary, on a leafless stem, 

 2-6 inches high, not differing in detail from W. gracilis. Ovary 2 or 3-celled. 

 W. gracilis, (partly) P. v. M. 



Summit of Mount Wellington. Fl. Dec. -Jan. 



Oedee XLIV. eric AC em. 



Calyx inserted below the ovary, tubular at the base, but deeply divided into- 

 5 segments. Corolla inferior, tubular, with 5 short spreading lobes. Stamens 

 10, inserted at the base of the corolla. Anthers 2-celled, usually with 2 or 4 

 awns, opening by terminal pores on slits. Ovary 5-celled, with many ovules in 

 each. Placentas axillary. Fruit capsular. Seeds minute. 



A very considerable order, distributed almost throughout the world, but very 

 poorly represented in Australian regions. The forms are very varied, but in the 

 definition of the order I have confined myself to details referring to Australian 

 forms.
