planted in autumn or late winter, and staked securely. Propaga- 

 tion is by seeds, which are poisonous; but budding and grafting are 

 practised in the nurseries. The genus was once included with 

 Cytisus, the common Laburnum being known as Cytisus Laburnum. 

 It is now Laburnum vulgare. There are several varieties, such as 

 the yellow-leaved, aureum; and the Oak-leaved, quercifolium. 

 There are several varieties of the Scotch, Watereri being good. One 

 of the most interesting of the Laburnums is Adami (syn. Cytisus 

 Adami), with purple flowers, which resulted from grafting Cytisus 

 purpureus on the common Laburnum; several shoots grew from 

 the graft, and the most vigorous one, propagated separately, gave 

 all the plants now known as C. Adami. Some specimens give a 

 peculiar example of reversion, for one bud on a tree will give the 

 yellow Laburnum, while others on the same tree revert to the 

 purple parent. Both species are fertile, but the hybrid itself is 

 sterile. In other trees the hybrid remains fixed.

Laelia (lae-lia, after the vestal virgin Laelia. Ord. Orchidaceae) . 

 Beautiful hothouse epiphytal Orchids, resembling Cattleyas, 

 with which they have been crossed. The cultural remarks made 

 under Cattleya apply to them. The following are the principal 

 sorts: anceps, winter bloomer, and its varieties, such as alba, Ash- 

 worthiana, and Percivalina, different colours (see the Botanical 

 Register, t. 1751). Autumnalis, winter, various colours, sweet 

 (Botanical Magazine, t. 3817); alba and atro-rubens are good 

 varieties. Cinnabarina, cinnabar, spring. Perrinii, winter, red and 

 white. Pumila, autumn, various colours. Purpurata, late spring, 

 purple, etc. ; several varieties, such as alba, atropurpurea, and 

 Schroderae. Tenebrosa, late spring, brown and purple; the Tring 

 Park and Walton Grange varieties are good. There are many 

 hybrids between the above species, also bigeneric hybrids between 

 Laelias and Cattleyas; and trigeneric hybrids between Laelias, 

 Cattleyas, and Brassias. For these a modern work on Orchids 

 should be consulted, as they are counted by scores, and the 

 descriptions are highly technical. 



Laelio-Cattleya. See above. 



Lagurus ovatus, Hare's-tail Grass (lagu-rus, from lagos, a hair, 

 and oitra, a tail. Ord. Gramineae). For culture, see Annuals 

 Grasses.

Lamium/Dead Nettle (la-mium, Pliny's name. Ord. Labiateae). 

 L. maculatum is the only species grown to any extent. It thrives 

 in ordinary soil, and is propagated by division in spring, or cuttings. 

 Aureum is a yellow-leaved variety.
