Logania
Belongs within: Loganiaceae.
Logania is a genus of shrubs found in Australia and New Zealand.
Characters (from Black & Robertson 1965): Shrubs; leaves connected at base by a more or less distinct stipular line. Flowers small, in corymbose dichotomous or trichotomous axillary and terminal cymes, with two opposite bracts at each branching of peduncles, rarely clustered. Calyx 5-sect, usually purplish or blackish; corolla usually white, with five imbricate, rounded spreading lobes about as long as tube; stamens 5; ovary two-celled, with several ovules in each cell; style simple, with capitate or oblong stigma; capsule coriaceous, ovoid and contracted towards summit, dehiscing septicidally and loculicidally at summit, so that it appears to open by four teeth, the two carpels finally almost separating.
