Logania
(named after James Logan, 1674-1751, born in Ireland, afterwards Governor of Pennsylvania, a writer on botany). SYN. Euosma. ORD. Loganiaceae. A genus comprising twenty-one species of greenhouse, glabrous herbs or sub-shrubs. Three are natives of New Zealand, and the rest are confined to Australia. Flowers white or flesh-colour, often small; corolla campanulate, or tube cylindrical, sub-hypocrateriform; lobes five, rarely four, spreading; cymes terminal or axillary, sometimes loosely trichotomous, occasionally in a sessile head, sometimes reduced to a single flower. Leaves opposite, entire, connected by a raised stipular line or short sheath, or rarely with small setaceous stipules. Loganias require a well-drained compost of sandy loam and fibry peat. Propagated, during summer by nearly-ripened side shoots, placed in a sandy soil, under a bell glass. Probably the two species described below represent all introduced.
L. floribunda (bundle-flowered). fl. white; racemes axillary, compound, shorter than the leaves. April and May. l. lanceolate, attenuated at both ends, smooth; stipules lateral, setaceous. h. 2ft. to 3ft. Australia, 1797. (L. B. C. 1118; A. B. R. 520, under name of Euosma albiflora.) L. latifolia (broad-leaved). fl. white, disposed in terminal panicles, composed of opposite, dichotomous, and trichotomous peduncles. Summer. l. obovate, acutish at both ends. h. 3ft. to 4ft. Australia, 1816.
