Hoya lasiantha and H praetorii

This is a couple of exceedingly beautiful and closely related Hoyas ....
....Hoya lasiantha, found in Peninsula Malaysia and Borneo - has larger golden flowers with prominent corona protruding like eroded molars.
.... the umbels on my palm somehow reminded me of a hatchling of small chicks.

Unlike most Hoyas, it is a scrambling shrub. It is reported to be an epiphyte in the wild. It is not a difficult plant to grow in the lowlands, but can become straggly, so constant prunning is advisable to keep it neat and will also provide some backup cuttings in case something catastrophic happened to the mother plant.
....under suitable lighting, the white hairs seem to emit a silver glow.

The second plant, Hoya praetorii, is a rarer prospect, and smaller in stature too. Unlike the former, this a a decidedly more difficult plant for me. This is a native of Sumatra.

It differs from the former by its corona,which is salmon-pink, less massive and less angular than its bigger relative.
