Cattleya maxima Cattleya maxima Cattleya maxima is a species of orchid in subfamily Epidendroideae found from Venezuela to Peru. Epiphytic herb with club-shaped pseudobulbs, up to 39 cm. or taller with one leaf at the top (total height of pseudobulb and leaf about 61 cm). Leaf oblong or broadly oblong, rounded at apex, light green, up to 35 cm. long and up to 6 cm. wide, thick and fleshy. Inflorescence stem up to 30 cm long, with 3-6 (upland variety) or 12-15 (lowland variety) flowers. Flowers 12–15 cm wide, with lilac or pale rose sepals and petals, except the lip or labellum,
Flowering plant in the range of 250,000 to 400,000. This compares to around 12,000 species of moss or 11,000 species of pteridophytes, showing that the flowering plants are much more diverse. The number of families in APG (1998) was 462. In APG II (2003) it is not settled; at maximum it is 457, but within this number there are 55 optional segregates, so that the minimum number of families in this system is 402. In APG III (2009) there are 415 families. The diversity of flowering plants is not evenly distributed. Nearly all species belong to the eudicot (75%), monocot (23%), and
