Larrea 



( 477 ) 



Lathyrus 



LARREA. 



Greenhouse evergreen shrubs (ord. Zygophylleae) 

 of little decorative value. Mexicana yields a glue 

 which is used by the North American Indians to 

 fasten their arrow heads, and also as a remedy for 

 rheumatism. 



LASIANDRA (** TIBOUCHINA). 



LASIOPETALUM. 



Greenhouse evergreen shrubs (ord. Sterculiaceaj), 

 seldom grown, and of little use to the gardener. 



LASIOSIPHON (.//. LACIIN.KA). 

 Greenhouse evergreen shrubs (ord. ThymelEea- 

 ceie) of little value. 



LASIOSPERMUM. 



Annual or perennial herds (ord. Composita>). 

 Propagation is by seeds for the annuals ; and seeds, 

 root division, and cuttings for the perennials. Any 

 ordinary garden soil will do. 



Principal Species : 



pedunculare, 6". Lancisia, Lidbeckia. | 



radiatum, 2' to '2'/, hlf- and Matricaria bipin- 



hdy. per., wh. (/.<. uata). 



LASTHENIA (syn. KAXCAGUA). 



A small genus (ord. Composite) of half-hardy 

 annual herbs, usually glabrous. They have yellow 

 (lowers, opposite leaves, and are showy, easily 

 grown subjects. Seeds may be sown in September 

 and October, under glass, and planted out early in 

 the spring ; or sown in April where the plants are 

 to flower. The plants should be well thinned. Any 

 ordinary garden soil suits. 



Principal Species and Variety :

LASTREA (sya. LASTR^EA). 



This once important genus has now been merged 

 in Nephrodium. There is one notable exception, 

 namely Lastrea aristata of gardens (set; figure), 

 which is now known as Aspidiuru aristatum. Lovers 

 of hardy Ferns still cling to Lastrea, and dilata- 

 tum (correctly a variety of spinulosuin) and its 

 numerous forms are sometimes styled Lastrea in 

 gardens. 



LATANIA. 



A small genus of handsome, ornamental Palms 

 (ord. Palms;), very useful for decoration when 

 small. Propagation, by imported seeds, sown in 

 strong bottom heat, and afterwards accorded a 

 moist stove temperature. Soil, rich loam. All the 

 species do best when planted in a prepared border 

 enriched with bone meal. Latanias attain large 

 dimensions, and require much room when mature. 

 Borbonica makes a good pot plant.

LATERALS. 



The side shoots thrown out at varying angles 

 from a main stem or branch. The term is frequently 

 employed in connection with cultural operations. 

 Thus, in the single rod " system of training 

 Tomatoes, it is advised to keep all the " laterals 

 closely pinched out. In the Grape Vine, the 



LASTUEA (correctly AsrwirM) AHISTATA. 



shoots that are formed from the closely cut back 

 spurs are the laterals, and the secondary shoots 

 developed by these, from buds in the axils of the 

 leaves, are termed " sub-laterals." In the Peach 

 and Nectarine many of the lateral shoots, when 

 produced right and left from the branch bearing 

 them, are trained in to form fruiting shoots for 

 another season. A number of sub-laterals also 

 start, and these, as in the case of the Vine, are 

 kept pinched in. 



In the tying-in of laterals it is well to remember 

 that the more nearly they are tied in parallel 

 lines to the branch bearing them the greater will 

 bo the vigour of growth. The more they are 

 depressed, or bent down, the less vigorous will be 

 the growth. Shoots that tend to grow strongly 

 and fail to set flower buds, may often be made 

 fruitful by a timely depression, which, checking 

 the flow of sap, checks also over luxuriance. Con- 

 versely, wec-ik shouts may be strengthened by rais- 

 ing them somewhat, even if it be only temporarily. 



LATHRvEA. 



A small genus (ord. Orobanchacea;) of hardy, 

 leafle.ss, herbaceous plants, parasitic upon the roots 

 of trees. The flowers are showy, and the plants 

 are both curious and interesting. Seed should be 

 sown near the respective host plant*. Two or 

 three years elapse from the date of sowing before 

 the seedlings arrive at the flowering stage.
