2. LOGANIA, E. Br. 



(After J. Logan.) 

 (Euosma, Andr. not ofWilld.) 



Calyx 5-oleft, rarely 4-oleft. Corolla campanulate or with a cylindrical tube ; 

 lobes 5, rarely 4, imbricate in the bud. Stamens 5, rarely 4, inserted in the 

 tube ; anthers linear or ovate, included or exserted but shorter than the corolla. 

 Ovary 2-Qelled, with several ovules or rarely only a single one in each cell ; style 

 simple, with a capitate or oblong undivided stigma. Capsule ovoid oblong or 

 globular, septicidally dehiscent, the carpels almost separating, opening inwards 

 by a longitudinal slit, leaving the placentas at length free without any pulp. 

 Seeds ovoid or more or less peltate. — Herbs undershrubs or shrubs. Leaves 

 opposite, connected by a raised stlpular line or short sheath or rarely with small 

 setaceous stipules. Flowers white or rarely flesh-coloured, usually small, in 

 terminal or rarely axillary cymes or panicles, or sometimes solitary, often more 

 or less unisexual. Bracts small. 



The genus is almost limited to Australia. 



Sect. I. Eulogrania. — Calyx-segments obtuse. Stamens inserted in the middle of the tube; 

 anthers included. Stems shrubby, at least at the base. Floiaers more or less dioecious. 



Leaves linear or lanceolate. Cymes axillary 1. L.floribunda. 



Leaves sessile, deeply cordate. Cymes axillary and terminal, in a long narrow 



thyrsoid leafy panicle . 2. i. cordifolia. 



Sect. II. Stomandra. — Calyx-segments acute or rarely rather obtuse. Stamens inserted 

 in the throat; anthers exserted (but not exceeding the corolla-lobes). Herbs or undershrubs. 

 Ilowers liermaphrodite. 



Low, braaohing, slender, erect or diffuse, leafy herb. Leaves small, ovate- 

 oblong or lanceolate. Flowers all solitary in the axils 3, L. pusilla. 



1. Ii. floribunda (free-flowerer), R. Br. Prod. 456 ; Benth. Fl. Austr. iv. 

 364. An erect shrub, attaining several feet, glabrous or slightly pubescent, the 

 branches more or less angular. Leaves lanceolate or linear, acute acuminate or 

 rather obtuse, narrowed into a short petiole, flat or with revolute margins, pale 

 underneath, with a prominent midrib, otherwise almost veinless, 1^ to 3in. long. 

 Flowers small, usually 5-merous but occasionally 4-merous, in axillary trichoto- 

 mous cymes or panicles much shorter than the leaves, rarely reduped to almost 

 simple racemes. Calyx-segments broad and obtuse, shorter than the corolla- 

 tube, minutely ciliolate. Corolla 1 to If line long, the lobes very broad and 

 obtuse, shorter than the tube, the tiiroat often slightly thickened inside and 

 glabrous or slightly pubescent or bearded. Anthers included in the tube, ovate. 

 Female flowers usually rather smaller than the males. Capsule rather narrow, 

 about 2 lines long. — DC. Prod. ix. 25 ; Endl. Iconogr. t. 57 ; Lodd. Bot. "Cab. t. 

 1118 ; Euosma albiflora, Andr. Bot. Eep. t. 520 ; Logania angustifolia, Sieb. in 

 Spreng. Syst. Cur. Post. 59 ; DO. Prod. ix. 25. 



Hab.: Southern localities. 



This species is usually distinguished from most others by " lateral setaceous distinct stipules." 

 The short, sometimes scarcely prominent, sheath or raised line connecting the leaves, appears 

 to me to be nearly the same in all the species, although in L. floribunda it is more decidedly 

 pubescent-ciliate. The truly axillary inflorescence appears, however, to be a constant distinctive 

 character. The flowers are frequently, but perhaps not quite so constantly, dioecious as in the 

 other species. — Benth. 



2. It. cordifolia (leaves heart-shaped), Hook. in. Mitch. Trop. Austr. 841 ; 

 Benth. Fl. Austr. iv. 364. A tall glabrous and glaucous erect perennial or 

 undershrub, the branches smooth and terete. Leaves sessile, deeply cordate 

 with rounded auricles, ovate or lanceolate, acute, 3 or 5-nerved at the base, 

 1 to 2in. long. Flowers small, in little compact triehotomous cymes forming 

 numerous thyrsoid panicles, terminal or in the upper axils, sessile and compact
