From Dale Kloppenburg’s Publication Paper: This new hoya species is not like any other present hoya species in that the apical
area of the outer coronal lobe is concealed (thus the name “celata”), bent sharply under
and hidden but most surprising is that it is bilobed. The corolla flattened is larger then
Hoya recurvula, and the curved under coronal apex is bilobed, anthers are much longer
and with the pollinia longer.”
