This is the most extensively grown genus of fan- 

 leaved palms in commercial horticulture of the present 

 day, its commonest representative being the well-known 

 "Chinese Fan Falm,"Z'. Chinen^is,\\h\c\\ is also known 

 to the trade, and improperly, as Latania Borhonica. In 

 general, the members of this genus are hy no means 

 difficult to grow, though it is well to make some distinc- 

 tions in culture between such strong-growing and com- 

 paratively hardy palms &,s L.CUinensls andi. austrfilis, 

 and the more "tender species from Java and northern 

 Australia, among which IJ. humiUs, L. oUvfeformis and 

 /y. rotundifoUa are prominent. 



For those of the first section a strong loamy soil well 

 enriched with thoroughly decayed stable manure, good 

 drainage, an abundance of water and a night tempera- 

 tare of G0° will provide satisfactory conditions for 

 sturdy growth. 



The more tropical species,j)f which I/. rotundifoUa is 

 a good example, make better progress in a somewhat 

 tighter soil and a higher temperature, G5° to 70° being 

 more congenial to them than the cool treatment accorded 

 their stronger relatives. More shade is also required for 

 the warmhouse species, in order to retain the rich green 

 color that a healthy Livistona should present. 



Red spider and white scale are two of the most trouble- 

 some insects to the grower of Livistonas, the first being 

 controlled to a great extent by thorough syringing, while 

 the latter may be eradicated by the careful use of various 

 insecticides, though avoiding the frequent application 

 of extract of tobacco, the continued use of the latter 

 substance often resulting in injury to the foliage of 

 Livistonas. 



i. australis is a more stubby-growing plant than L. 

 Oh inen^ is, the fan-like leaves are stiff er and less grace- 

 ful, and the footstalks are more thoroughly armed with 

 stout spines, while the leaves are also smaller in propor- 

 tion to the plant than those of X'. Gliinensis. L. Hoogen- 

 dorpii and L. oil cce for mis are somewhat alike in young 

 plants, but the first has many more and coarser gpines 

 on the footstalks, and the stalks of L. Roogendorpii are 

 generally longer, the leaves of both being much divided. 

 L. rotnndifolia and L. aJfisRima are much alike in a 

 small state, and the writer is inclined to think that the 

 seeds of the latter are sometimes substituted for those 

 of L. rotnndifolia. The leaves of L. rotnndifolia are flat- 

 ter and more even in outline, those of L. alUssima being 

 somewhat undulated, as though they were crowded on 

 the stalk. In fact, small plants of L. rofu)idifolia are 

 usually more symmetrical, and also have longer foot- 



stalks.

LL6YDIA (after Edward Lloyd, w^ho found the plant 

 in Wales). Lilidcea^. About 4 species of bulbous plants, 

 of which L. alpina was said by Baker to have the widest 

 distribution of any plant in the lily family. Dwarf 

 plants, with hard, grassy Ivs. and small, whitish, long- 

 lasting fls.: perianth G-parted; segments wntliering and 



persistent ; stamens G, hypogynous, shorter than the 



perianth: capsule obovoid; seeds flatfish. 



alpina, Salisb. [L. serdtlna, Sweet). Distinguished 

 from the other species by having an oblique, somewhat 

 rhizomatous rootstock and glands on the claws of the 

 perianth segments. Radical Ivs, 2-4, linear, convolute: 

 stem usually 1-fld., 3-9 in. long: Ivs. 3-4, small, linear: 

 fls. whitish, yellowish purple at its base. Mts. of Wales 

 to Sicily, Himalayas, Colorado.— Adv. 1889 by. F. H, 

 Horsford. 



LOASA (South American name). Loashcece. These 

 plants are too much like nettles to deserve cultivation, 

 though their fls. are odd and interesting. The paiii 

 from their pricks lasts several days. Each of the 5- 

 hooded petals contains a bunch of stamens. They are 

 treated as half-hardy annuals, {^(^.g. Annuals.) A ge- 

 nus of about 50 tropical American herbs, erect or twin- 

 ing: Ivs. alternate or opposite, entire, lobed or decom- 

 pound: capsule 3-5-valved from the ai:)ex, rarely twisted: 

 ovary 1-celled; ovules numerous. The allied genus 

 Blnmenbachia differs in having capsules which aro 

 longitudinally 5-10-valved and most frequently spirally- 

 twisted.

 B. Petals yellow. 

 hispida, Linn. Annual, 1?^ ft. high: Ivs. alternate,

 pals much shorter than the petals; petals yellow, over 

 1 in. long. June-Aug. Peru. B.M. 3057. G.C UI.

 ments serrate, each with a long stalklet, the lateral 

 ones often divided into 3 Ifts. : sepals shorter than the
