Cattleya alaorii Cattleya alaorii Cattleya alaorii, commonly known as the Laelia alaorii, is a species of orchid endemic to Brazil (Bahia). The species was named after Mr. Alaor Oliveira, former employee at the University of São Paulo at Piracicaba, who first collected this species in a field excursion in the late 1960s. It was discovered in the 1970s in an isolated mountain chain near Itabuna, Bahia state. It grows in the very wet Bahia coastal forests ecoregion of the Atlantic Forest biome ("Mata Atlantica Brasileira"). It is found in rainforests at about above sea level. The plants are epiphytes in tall trees
Flowering plant group of the other flowering plants, and morphological studies suggest that it has features that may have been characteristic of the earliest flowering plants. The orders Amborellales, Nymphaeales, and Austrobaileyales diverged as separate lineages from the remaining angiosperm clade at a very early stage in flowering plant evolution. The great angiosperm radiation, when a great diversity of angiosperms appears in the fossil record, occurred in the mid-Cretaceous (approximately 100 million years ago). However, a study in 2007 estimated that the division of the five most recent (the genus "Ceratophyllum", the family Chloranthaceae, the eudicots, the magnoliids, and the monocots) of
