THE TASMANIAN FLORA. 



129 



2. LTONSIA. 



Oorolla-tnbe cylindrical, often very short. Lobes narrow, spreading, more or 

 less bearded on the upper surface. Stamens inserted low down in the tube. 

 Anthers narrow, cohering in a ring round the style. Ovary 2-celled, with many 

 ovules in each. Fruit an elongated capsule or combined follicles. Placenta 

 axillary. Seeds with a tuft of hairs. 



A small, purely Australian, genus. 



L. STEAMINEA, jR. Br. A slender climber, often ascending trees to a 

 considerable height. Leaves broadly lanceolate, 2-4 inches long, opposite, shortly 

 stalked. Flowers numerous, in irregular compound panicles towards the ends of 

 the branches. Calyx about 1 line long. Corolla-tube about as long as calyx. 

 Lobes spreading,! about 2 lines long, bearded towards the base. Stamens forming 

 a cone. Fruit about 2-3 inches long, the carpels separating when dry, leaving 

 the placentas and seeds attached to the common septum. 



Common in shady places, chiefly in the north, Waterworks (Hobart), 

 Macquarie Harbour, near Remine, near Kingston ; also in New South Wales and 

 Victoria. Fl. spring. 



Obdee h.—LOGANIACE^. 



Flower regular. Calyx tubular, free from ovary, the lobes usually 4 or 6, 

 occasionally 2, rarely 6 or 7. Corolla gamopetalous. Lobes usually 4 or 5, 

 Stamens similar in number to lobes of corolla, and inserted into the tube. 

 Ovary mostly 2-celled, rarely 3-5, the dissepiment sometimes imperfect. Style 

 single, or more or less divided into 2. Stigma bilobed. Ovules 1 to many in 

 each cell. Fruit a capsule or berry. Leaves opposite. The order is small, and 

 includes rather diverse types intermediate, in many respects, between Mubiacece, 

 Apocynacem, and GentianacetB. 



It is widely distributed in both Hemispheres, but principally in warm pi a ces 

 In Tasmania only one genus is represented. 



MITRASACME. 



Calyx 4 or 2-lobed. Corolla-tube a short or elbngated cylinder. Lobes 4.. 

 Stamens 4. Ovary 2-celled. Ovules several. Style usually simple, but dividing- 

 more or less as the pistil matures. Fruit a variously-formed capsule. 



Excepting 2 or 3 from tropical Asia the genus is Australian. 



Calyx 4-lobed. 



Calyx divided nearly to base. 



Capsule ovoid, with 2 erect styles ... ... L M. archeri. 



Capsule compressed, triangular, with spreading 

 styles 

 Calyx divided to the middle. 



Corolla-lobes much exceeding tube 

 Corolla-lobes much shorter than tube . . . 

 Calyx 2-lobed. 



Styles cohering in mature flower 



Styles distinct in mature flower ... ... ... Q. M. distylis. 



1. M. AECHERi, Hook. A small, glabrous, densely-tufted perennial. Stems 

 seldom attaining 1 inch. Leaves of a tough consistency, shining, oblong, blunt, 

 margin transparent, crowded, about 1 line long. Flowers nearly sessile, in the 

 terminal- axils. Calyx-tube very short, the lobes leaf -like, 2 about 1 line long and 

 obtuse, the inner 2 shorter, narrower, and acute. Corolla-tube broad, nearly I
