 Cyrtopodium witeckii (flor estendida) |
Terrestrial plant of mountain slopes with rocky outcrops in the
Santa Maria, Rio Grande do Sul and belonging to that group of species
of Cyrtopodium which vegetate in nature with the pseudobulbs completely
buried in the soil. They are ovoid with 5.0cm height and reddish brown color; It has 5 leaves that ar coriaceous, plicate and oblong-lanceolate, with 27.0cm long and 4.0cm wide at the middle part, the leaves are up-right and compete with the height of the floral spikes that are, in general longer but, sometimes, they can be shorter. The inflorescence is green without branches. In the group of the studied plants, it and is 30,0 cm height; the flowers are ornamental, scented, numerous (15) forming a group, with 3,0 cm diameter. Basically, when they open, they present a delicately yellow-greenish color and then become only greenish; the apical parts of the petals and sepals are slight stained with brown-reddish blotches and spots; the trilobate lip is entirely purple showing a yellow warty which gives a peculiar beauty to the flowers |
| We should
point out that at first glance the flowers of this new species can
be confused with those of Cyrtopodium brandonianum, but the
morphology of the plant itself certifies how the two species are different Blooming copiously in the first half of October 2009, Brazilian spring, in a habitat at 270 m altitude in a very steep hillside, the populations of Cyrtopodium witeckii can be safe from environmental depredations, illegal harvesting of plants and improper land use in face the difficult to access the habitats. The name "witeckii" was given in honor of Professor Leopold Witeck Neto (Forest Engineering / Polytechnic School of Universidade Federal de Santa Maria, RS) in the face of his interest and collaboration in researches involving the discovery of new species, as well as his activities conservationists in Santa Maria, RS. |
