Hoya Sp Sidikalang (Hoya sultan super rare).

Hoya sp Sidikalang (super rare Hoya sultan), endemic to North Sumatra province, Indonesia. is included in the very rare category and is no longer found in its natural habitat. recommended to be found in 2020 in the interior forest of Sidikalang, Dairi district on the border with Aceh district, North Sumatra province, Indonesia. This Hoya belongs to the stem Hoya type, such as Hoya Amicabilis, Hoya no id sp Tanggamus, Hoya no id newest sp Bengkulu, Hoya sp Garut, Hoya sp Cianjur, Hoya mini bell and Hoya sp Magetan. but I explained that even though they all have the same stems and leaves, they all have different flower shapes and color structures (not the same). I call this Hoya the Hoya sultan (Hoya of collectors), because it is very rare and no longer found in its habitat and the flowers are dark red with a yellow center. There are 2 types of leaf color, namely dark green and brownish red, depending on the temperature adaptation found in the forest.
