LUXEMBERGIA (syn. PLECTRAN- 

 THEBA). 



Branching stove trees and shrubs (ord. Och- 

 nacese) from Brazil. They may be propagated by 

 cuttings of firm shoots rooted in a close frame, in 

 sandy soil, with bottom heat. Peat and loam in 

 equal parts, with sand, suit for compost. Eare in 

 cultivation. 



Principal Species : 

 ciliosa, 8' to 12', sum., polyandra, yel. (syn. 



yel. corymbosa) . 



LUZULA. 



Perennial Grass-like plants (ortl. Juncacese) of 

 no garden value. Five or six species are natives of 

 Britain. 



LUZURIAGA (syns. CALLIXENE and 

 ENARGEA). 



Half-hardy branching greenhouse shrubs and 

 sub-shrubs (prd. Liliacese), with white flowers and 

 round berries. They may be increased by cuttings 

 rooted in sandy peat. The plants should be grown 

 on blocks of peat, and require plenty of moisture 

 and shade to do well. They are rarely met with 

 in gardens.

LYCASTE. 



Description. A group of useful plants (ord. 

 Orchidaceae), from Tropical America and the West 

 Indies. They all have thick and firm pseudo-bulbs, 

 and these in some species are very short, nearly 

 all being ribbed or angled. . Leaves are produced 

 singly or in pairs (rarely in threes) at the apex of 

 the pseudo-bulb ; they are plicate (folded), and vary 

 in length from a few inches to 2J', with a width of 

 3" or 4". Flowers are borne singly, on stout 

 scapes rising from the base of the bulb ; they are 

 large, showy, and substantial, lasting a long time 

 in good condition. 



Propagation. By division after the plants have 

 flowered. 



Lussacla (sec Oaylussania). 



Soil. In the matter of compost Lycastes are not 

 nearly so fastidious as most Orchids. They will 

 flourish in pure peat, but the stronger growers are 

 the better for an addition of fibrous loam. Good 

 drainage is essential. 



Other Cultural Points. A summer temperature 

 of from 60 to 80, with a further rise on hot 

 days, provided air is admitted freely, will suit, 

 while during winter 50 to 60 will be ample. The 

 more vigorous species, like gigantea, costata, 

 Skinneri, etc., can be grown successfully at the 

 warmer end of a cool Orchid house all the year 

 round. As all Lycastes have a distinct season of 

 rest, though all are not deciduous, care in ad- 

 ministering water when growth is in abeyance 

 is essential, or much harm may result; on the other 

 hand, when growing ffeely, abundance of water is 

 needed, and established plants are frequently 

 improved by occasional doses of weak liquid 

 manure. 



Insect Pests. Lycastes are not much troubled by 

 insects, but occasionally scale and mealy bug find 

 shelter between the ribs on the under side of the 

 leaf.. Regular sponging is the best remedy. 



Paphinia Group. Though included botanically 

 with Lycastes, the Orchids generally known as 

 Paphinias are distinct horticulturally. The scapes 

 are pendent. Grow in suspended baskets, in the 

 moist atmosphere of a stove, using a compost of 

 peat and sphagnum. Shade from bright sun, and 

 water sparingly when not growing.
