LOISELEURIA 
[Placed in Passiflorales by Benth. -Hooker, in Passiflorinae by 
Warming.] 
Loaseae (Benth. - Hooker) = Loasaceae. 
Lobelia Plum, ex Linn. Campanulaceae (ill). 200 sp. trop. and 
temp. ; 2 in Brit., one in lakes (Z. Dortmanna L.). Several are 
commonly grown in gardens. The flr. (see order) is twisted upon its 
axis through 180 0 , and is zygomorphic. The anthers are syngene- 
sious as in Compositae and the style pushes through the tube thus 
formed, driving the pollen out at the top. Finally the style emerges, 
the stigmas separate, and the female stage begins. Not uncommonly 
the style is unable to push through the tube, or at least does not do 
so, and self-fertilisation occurs when the stigmas open. [See order, 
and compare Campanula, Phyteuma, Jasione and Compositae.] 
Lockhartia Hook. Orchidaceae (28). 20 sp. trop. Am. No tubers; 
leaves crowded together. 
Lodoicea Comm. Palmae (11. 3). 1 sp. Z. Sechellaram Labill., 
Seychelles (p. 148), the double coco-nut or Coco de mer. Dioecious, 
with enormous spadices. The fruit is the largest known and takes 
10 years to ripen. The nut is bilobed. The fruits used to be found 
floating in the Indian Ocean long before the tree was discovered 
(see Treas . of Bot.). 
Loeflingia Linn. Caryophyllaceae (11. 3). 5 sp. Medit., Cent. As., 
N. Am. 
Logania R. Br. Loganiaceae. 21 sp. Austr., N.Z. 
Loganiaceae. Dicotyledons (Sympet. Contortae). 32 gen. with about 
350 sp. of trop. plants. A few occur in warm temp, regions (Am., 
As., N. Z., but none in Eur.). They include trees, shrubs, and herbs 
with opp. stip. leaves; the stipules are often very much reduced. 
Many are climbing plants, of which Strychnos is especially interesting. 
The infl. is as a rule cymose, of very various types; the firs, with 
bracts and bracteoles, usually regular, $ , and 4 — 5-merous, with 
occasional increase in number in corolla and androeceum. Disc small 
or absent. K (4 — 5), imbricate; C (4 — 5), valvate, imbricate, or con- 
volute ; A 4 — 5, rarely 1, epipetalous; G (2), anteroposterior, 2-loc., 
or rarely imperfectly so, or 1- or more-loc. ; style simple; ovules 
usually cc, amphi- or ana-tropous. Capsule, berry, or drupe. 
Endosperm. The L. are nearly allied to Apocynaceae, Gentianaceae, 
Solanaceae, Scrophulariaceae and Rubiaceae. See full discussion by 
Solereder in Nat. PJl . Chief genera: Logania, Spigelia, Strychnos, 
Fagraea, Buddleia, Desfontainea. [Placed in Gentianales by Benth.- 
Hooker, in Contortae by Warming.] 
Loiseleuria Desv. Ericaceae (1. 3). 1 sp. Z. procumbens Desv. [Azalea 
procumbenslu), the trailing Azalea, north circumpolar. It is found in the 
Highlands of Scotland, where in parts the flat hill tops are carpeted 
with it (p. 182). The leaves are very wiry, and rolled back at the 
margins, thus protecting the stomata from too free transpiration. The
