Resumen:
Clitoria cordobensis Burkart is an endemic
perennial herbaceous plant of the mountain ranges of Cordoba. The objective of
this work was to study the typology of the synflorescence and floral morphology. Studies at field were
made during years 2003 to 2007 in four natural populations that grew in the
Punilla Valley, Córdoba. Samples were taken for their later analysis in the
laboratory. The plants have aerial orthotropic axes with little buds of
innovation and with very few branches with voluble apexes and truncated
polytelic synflorescence.. The paraclade
is reduced to its coflorescence, hypotagma is not developed, the axis is very
short and presents between 4-6 flowers in axillaries fascicules. Chasmogamic
and cleistogamic flowers were observed,
these were reduced to a small calyx, did not possess corolla, the androecium
was reduced to only three stamens, the position of the anther of the vexilar
stamen coincided, and it leaned in the stigmatic surface, the style was short
and curved. The ovarian development was manifested immediately, the style was
not extended, stigma was separated of the anther by the growth of the fruit.
According to the observed data the increase of cleistogamic flowers at the end of the flowering
guarantees the production of fruits and seeds.
