Hoya that are less likely to survive a long trip and should be bought as big and established as possible are :
Hoya acicularis
Hoya aff. Sigillatis
Hoya blashernaezii
Hoya campanulata
Hoya camphorifolia
Hoya danumensis

Hoya filiformis
Hoya imbricata
Hoya megalaster
Hoya microstemma
Hoya odetteae
Hoya parvifolia

Nota : these cuttings certainly can survive long trips : Horticulture can be a serious thing using hormones or products that tremendously modify the survival rates of stressed plants.
