Read about Laelia in the Standard Cyclopedia of Horticulture 

Laelia (meaning uncertain). Orchidaceae. A useful and attractive group of orchids, mostly with large, showy flowers borne singly or in two- to

many-flowered racemes, which arise from the top of one- to two- leaved pseudobulbs. The plants greatly resemble cattleyas and differ only by the

presence of eight perfect pollen masses instead of four.

Leaves oblong, coriaceous or fleshy, not plicate: pseudobulbs terminating the annual growth, ovate, clavate, fusiform or st.-like, long or short,

consisting of 1 to several thickened internodes, or of slender and quill-like form with merely a small bulbous swelling at base, sheathed with scales and

bearing 1 or 2 lvs. at the summit: sepals subequal, free, spreading; petals wider and sometimes longer, spreading; all usually plane; labellum free from

the base of the column, more or less distinctly 3-lobed, the lateral lobes short, erect, folding over the column; middle lobe long, expanded,

lanceolate-ovate, etc.; column concave in front, and thus narrowly 2-winged on the edges; pollinia 8, 4 in each locule; scape terminal, long or short,

bracted.— About 30 species, dispersed in the maritime provinces of Mex. and Guatemala and in S. Brazil. No species is common to the two widely

separated regions. A single species, L. monophylla, inhabits the mountains of Jamaica. In their native homes the plants are often found clinging to

bare rocks and trees, where they are exposed to the full force of the tropical sun, and, in the wet season, to daily drenching rains. Some of the species

grow at great altitudes. Thus, L. autumnalis var. furfuracea, is always found in alpine regions at elevations of 7,500-8,500 ft. For a list ot cult, kinds,

see R. A. Rolfe, G.C. III. 7:107, 256, 333, 355; 8:241, 652.

Laelia may be conveniently divided into groups, as follows:

Group I (species 1-10).—Pseudobulbs rounded, pyriform or ovate. The plants of this section are medium- sized, with the pseudobulbs terminating each

year's growth, sessile at intervals on the rhizome, and sheathed at least at first with bract-lvs. The scape, except in L. grandiflora, is long and slender,

erect, nodding or sub- horizontal, and bears at its end 1 or 2 fls. (L. anceps), or a raceme of 2-7 fls. (L. albida). L. grandiflora, placed here on account

of its thickened pseudobulbs, bears greater resemblance to the members of the next group.

Group II (species 11-13).—Pseudobulbs short-cylindrical, st.-like, or swollen-jointed, i. e., consisting of several internodes and sheathed with bracts.

These plants are of dwarf habit, bearing 1-2 very large fls. on short scapes, so that the top of the fl. scarcely exceeds the lvs., which are oblong, about

6 in. long, and leathery.

Group III (species 14-23).—Pseudobulbs long- oblong, fusiform or clavate, tapering below to a sheathed and jointed stalk. This group contains the

largest and most showy laelias. The pseudobulbous sts. are tall and tufted, a foot or more in length, forming robust, compact, almost bushy plants. The

flowering sts. of L. superbiens are said to attain a height of 12 ft. The racemes bear 3-7 large, handsome fls.

Group IV (species 24-26).—Pseudobulbs slender, reed-like and tufted. clothed with scales and often somewhat swollen at base. This group includes a

few species which are very distinct on account of their bright scarlet or orange-colored fls. and slender, reed-like pseudobulbs. L. monophylla is

perhaps the smallest of all laelias, being scarcely over 6 in. high, with pseudobulbs about as thick as a crow-quill. One variety of L, cinnabarina has

purple fls.

Cultivation of laelias. (E. O. Orpet.)

These orchids have ever held an important place in gardens, and were it not for the trifling generic distinction of having double the number of

pollen-masses of the cattleya, they would have been known as a part of the last named, the ease with which both have been hybridized even from the

beginning proving the close affinity; and one authority at least is willing to merge the two, were it not for the mixing up it would cause in garden

nomenclature. The Brazilian species, L. purpurata and L. crispa, are strikingly beautiful, easy of culture, and are long-lived in gardens. These were

the first to be used by the hybridist, and the multiple crosses made since, with the later addition of L. tenebrosa, show evidence of the gorgeous

coloring of the labellum due to the laelia parentage.

It has always been the impression that the Brazilian laelias require very much warmth to enable them to grow well. This has been proved to be an

error, as stronger growth is made in an intermediate temperature. The plants get an absolute rest in winter, flower better and grow stronger when kept

at a temperature of about 50° in winter.

The Mexican kinds that mostly flower in midwinter, such as L. anceps and its white forms, will do equally well in a similar house, but are best grown

outdoors in summer in the partial shade of overhanging trees, giving a spraying of water overhead at evening of each hot day. This has been found to

be the only way to get the white forms to bloom freely, as they need special treatment and thorough ripening to secure good results. Removal indoors

should take place before frost; cool nights seem to invigorate them, but while they experience slight frosts in Mexican uplands, it is harmful here.

These laelias make an abundance of roots, and the plants should be kept off the ground to avoid the danger of slugs. If these gain access, soak the

pots or baskets in water for an hour and the slugs will appear and can be caught.

The repotting of laelias must be done in early spring, or just before the appearance of the new bunches of roots at the base of the growths.

Native-born species have a regular way of living, but the hybrids have a go-as-you-please habit, due perhaps to their mixed origin, that makes the

repotting an operation that lasts throughout the year. Flowers are produced at all seasons, while, with introduced plants, their blooming is as fixed as

the days of the year. This makes it hard to make a rule when to repot or separate plants; but, should the roots begin to get outside the receptacle, it is

wise to give the plants more space. Good firm osmundine is the best material, as these are strictly epiphytal plants. Imported specimens are received

with mats of dwarf polypodium attached, and these often grow with the plants in cultivation, giving a clue to the best way to treat them afterward. The

other Mexican species, L. Gouldiana, L. autumnalis and L. albida, are not so durable in gardens as some others. They are most valuable

midwinter-flowering orchids; they need similar culture as that given to L. anceps, but have to be replaced by new specimens after a few years, as they

are not permanent.

There are many pretty dwarf-growing species, L. praestans, L. Dayana, L. pumila, L. grandiflora, L. Jongheana and others, that require extra care to

keep them in health, and this care is largely in the matter of moisture. The plants are small, need shallow pans and to be suspended close to the roof

glass where they dry out speedily, and unless moisture is given regularly, the health of the plants soon weakens. The drying out is desirable, for the

plants experience this on rocks or trees in their native habitat, but there they have the benefit of the night dews that amount to a shower of moisture;

this is easily imitated by spraying over the plants each dry evening. The roots will take this up during the night, and be fortified for the succeeding

day. If one examines the aerial roots of L. anceps, they will be found to be in segments, some longer than others, the longer ones being those formed

on a dull or wet day when evaporation was slower and the tender- growing tips could grow longer. This is suggestive in a cultural way.

plant there figured is probably the species in question, although, according to the figure and the accompanying description, the sepals and petals are

wider than those of L. anceps.

Laelia is a small genus of eleven species from the orchid family (Orchidaceae). This is one of the most important and popular orchid genera, because of the beautiful flowers, their genetic properties and because they are fairly easy in culture. It is probably named after Laelia, one of the Vestal Virgins. Another possibility is the name borne by female members of the Roman patrician family of Laelius.

They are found in the subtropical or temperate climate of Central America, but mostly in Mexico. Laelia speciosa is a high-elevation plant, preferring sunny, dry and cool conditions. The others grow in the rainforest with a warm, humid summer and a dry cool winter. The species L. albida, L. anceps and L. autumnalis prefer higher and cooler altitudes.

Most are epiphytes, but a few are lithophytes, such as Laelia anceps. They are closely related to Cattleya with only the number of pollinia differing. Stems are usually short, however the stem of Laelia anceps can be more than 1 m long. The ovate pseudobulbs are clearly separate. These are about 6 - 30 cm long. One or two waxy, leathery leaves develop from each pseudobulb. This leaf can be up to 20 cm long. The inflorescence is a raceme, which can be 30 cm long, with up to eight flowers, growing from the top of the pseudobulb. These flowers can be pink to purple, with a beautifully colored purple lip becoming white close to the column . They bloom in spring or autumn. Albino varieties are rare and therefore prized. Don't worry if you think you'll never own an albino Laelia. Due to tissue culture or mericloning, the availability of albinos are now available provided you find the right lab

Members of this genus tend to be fairly easy in culture, and some plants are surprisingly drought-tolerant. Culture is highly dependent upon the natural habitat of the species in question, although many do well as mounted (plaqued) specimens so that the roots receive plenty of air circulation and a sharp wet-and-dry cycle.

Many species from South America, which used to belong to Laelia, are now classified under Sophronitis (van den Berg and Chase Lindleyana 15 (2), page 115, June 2000). The taxonomic status of some of these species is somewhat in doubt as they were moved there on the basis of molecular phylogeny. It seems likely that some growers and taxonomists will reject these changes, and continue to accept these "Sophronitis" species as laelias.

Laelia species readily form hybrids within the genus, and with other genera, including Cattleya (x Laeliocattleya, more than 2,000 species), Brassavola, Rhyncholaelia, and Sophronitis. The majority of orchid hybrids belong to this category, i.e. x Sophrolaeliocattleya, x Brassolaeliocattleya and a number of other variations.
