Notes. Hoya krusenstierniana may be easily confused with the more common and 
widespread Hoya solaniflora which thrives at lower elevations of 1200-1800 m. Both 
sterile specimens and dry flowers of the two species can be easily confused as both 
species have variable leaf shape and thickness. In the living state Hoya krusenstierniana 
is easily distinguished by its purple to rich crimson flowers and by its scent, which is 
reminiscent of peeled unripe green bananas, whereas H. solaniflora has pale flowers in 
shades of white- yellow-pink and with a scent more similar to Gardenia jasminoides 
J.Ellis. Usually the corona is a key character for species delimitation in Hoya as 
it is very stable but obviously not for this taxon. The corona morphology of Hoya 
krusenstierniana is quite variable within the population on Mt. Kaindi (Fig. 16, 17) 
and is therefore not a good morphological character to distinguish the species. Instead, 
it is the intense crimson colouring (rarely pale pink) and the unusual flower scent that 
suggests a different pollinator than that of the similar Hoya solaniflora. 
Hoya koteka Simonsson & Rodda, sp. nov. 
Similar to Hoya multiflora Blume in its conical buds with five basal humps in line with 
the corolla lobe sinuses. However, Hoya koteka has single-flowered inflorescences 
while H. multiflora has inflorescences with numerous flowers. - TYPE: Indonesia,
