This habitat is placed in the River Araquá valley, between São Manoel and Botocatu cities, in the state of São Paulo.
The temperature in the winter is quite cold and can drop at less than 5º C.
There is a well defined drought season and the temperature during the rainy summer can get 31º C. The ground becomes swampy and, as the rains diminish, it is little by little drained without been totally dried. In some periods of the year, there is a sudden change of the temperature from day to night.
Brief : a typical description of a temperate climate.
Concerning the altitude, I can not say it precisely but it is less than 800m.
The valley is placed between the hills and small mountains which become smaller as the river goes towards Barra Bonita dam.
As we can see, there a big concentration of of Microlelia lundii and Cattleya loddigesii growing almost exposed to the full sun, however the hybrids is rare to be found and, another particularity, in this habitat, except for the species mentioned, there is no orchidaceae plant.
There are another close valleys with these two species, however many other species are abundantly found, such as Rodriguezia decora, Oncidium pumilum, Notylia sp, many species of Epidendrum such as latilabre, floribundum (=densiflorum), rigidum and many species of Pleurothallis, between others.
Another interesting particularity is that many of those trees which are replete of plants are died, some rot and drop in the water or over the vegetation.
Finally and more sad, this habitat, unfortunately, has apparently already been visited. We can find evident signs of predatory extraction. The area is very big and I believe it is difficult to have a efficient supervise, however I think it is correct to denunciate it.

There are occurrences registered to the Federal District (Brasilia) and to the states of de Goiás, Minas Gerais,

Mato Grosso do Sul, Paraná and São Paulo.
In spite of not being common in the state of Minas Gerais, it has been described from a plant collected there (Otia Botanica Hamburgensia 2: 92), as Bletia lundii Rchb. f. & Warm. in 1881. However, soon later, apparently in the same publication, Reichenbach f. described it again as Laelia. In the same year, Barbosa Rodrigues described the same species as Laelia regnellii and published it in Genera et Species Orchidearum Novarum 2: 154.
In l892, another description has been done under the name of Laelia reichenbachiana H. Wendl. & Kraenzl and published in Xenia Orchidacea 3(6): 97.
In 2000, Van den Berg & M.W. Chase proposed the transference to the genus Sophronitis as Sophronitis lundii (Rchb. f. & Warm.) C. Van den Berg & M.W. Chase, Lindleyana 15(2):117.
In 2002, Chiron & V. P. Castro established the genus Microlaelia to shelter this only species [Microlaelia lundi (Rchb.f) Chiron & V. P. Castro], published in Richardiana. II(1).24, taking the name of the section Microlaelia, according to the classification of the genus Laelia, adopted by Pabst & Dungs in Orchidaceae Brasilienses, vol I, 1975.
This species grows in small trees situated in inselbergs (on rocky outcrops)
or directly on the rocks, in shade places in gallery woods.
It blooms in winter, the small spikes bear from 1 to 3 flowers which do not exceed 4cm diameter.
This species requires temperate climate, well ventilated place and high humid environment and seems to need more luminosity than found in its habitat.
In São Paulo, there is the natural hybrid, result of the cross with Cattleya loddigesii Lindl. known as Lc x fredna and described under the L cattleyioides Rich. transferred to Microcattleya by V.P.Castro & Chiron [Microcattleya cattleyioides (Rich.) V.P.Castro & Chiron]

Cattleya loddigesii Lindl.


This species is found in the states of Bahia, Espírito Santo, Paraná, Rio de Janeiro mainly in Minas Gerais and São Paulo, in the hillsides of the mountains covered by the Atlantic Forest, in swampy and/or riparian areas, with heavy mist and temperate climate between 500 and 900/1000m altitude. In general, it is protected from the excessive luminosity and has high humid environment during the summer and a dried winter. It can also occurs in the summit of the hills, laying in the trunks of the trees receiving a strong luminosity.

The blooming period starts in the fall and goes through the springtime. The flowers are 9cm diameter, exceptional quality plants, they can reach 12cm.
It is a very close species to Cattleya harrisoniana Batem. ex Lindl.
It forms many natural interspecific and intergeneric hybrids, include second generation one:

Artificial Hybridizing

Cattleya loddigesii has been used in more than 5.500 crosses in 11 generations, forming interspecific hybrids such as Brassocattleya, Brassolaeliocattleya, Cattleytonia, Epicattleya, Epilaeliocattleya, Sophrocattleya, Sophrolaeliocattleya; Schombocattleya (and/or Myrmecocattleya) e Cattlychea (Prosthechea).
In cultivation
It is easier to be cultivated in temperate climate but it can grows well in warmer places mainly if the nights are colder.
It should be protected from the excessive luminosity, the environment should have high humidity during the hotter months when it should be frequently watered. Reduce the watering during the winter but be careful with the like cane stems, they wrinkled easily.
Improvement
Very appreciated plant, Cattleya loddigesii is one of the most improved Brazilian species and has been submitted to successive genetic improvements aiming to get rounder flowers without a gap between the segments and also to enlarge the fan colors. During the interview given to Orchid News (to be published in the next edition), Álvaro Pessoa tells us a little about the history of its improvement history. First, Adhemar Mannarini selected special clones and worked with them. He introduced in the market, during the 80 years, a quite expressive number of varieties obtained in the laboratory working with striated, punctata, punctassima, dark forms and so one. Other growers have also worked with this species, such as Harusi Iwasita who obtained high quality alba plants. Sebastião Nagase did an excellent work getting bright colors from dark specimens, besides Nagkashima and Aldomar Sander (the later in the south). In the state of Rio de Janeiro, Siegweald Odebrecht got light colored plants working with the clone ‘Martinelli'. Álvaro Pessoa himself has already participated in this group working with plants coming from Mannarini's laboratory.
Thus, nowadays, there is a great variety of color, from light to dark pink, punctata, punctatissima and the very required, alba variety.
