The first "whorl" of the flower structure in made up of 5 sepals at the
end of the pedicel and just outside of the corolla. In the flowers
development the calyx at first covers the whole flower bud. As the inner
parts maturate, they expands and the corolla pushes ever larger,
eventually for the most part hiding the small calyx. Most taxonomists
consider this structure so minor that some do not even include it in a
hoya description. It is, however unique in some species and has
structural characteristics that should be observed and noted. It can
vary in length, width, amount of overlap at the base of the sepals, its
central thickening, the amount and placement of indumentum (hairs) on
its outer surface, in edge ciliation. Occasionally with hair cells
inside and in the presence or absence, and number length etc. of a
tongue like structure at the sepal sinus area the "ligule"
