Adenium Arabicum - Yak Saudi
Its origin lies in southern and western Arab peninsula. The trunk is tall and big. The leaves have delicate hair. The flowers are pink and of small size. It blossoms at the branches and its trunk. The pods are usually red. The pods and seeds are big. This breed can be divided into two parts according to its trunk shape.
- Tall trunk like a perennial trunk: The trunk is tall. The trunks grow straight out of the caudex. The trunks grow better vertically. It was reported to be seen as tall as 4 meters in Thailand, named "Yak Wang Na".
- Short trunk: The trunks grow out of the base of the caudex. They grow better horizontally. The caudex's base is huge. It can be as huge as 1 meter and 2.50 meters high which was seen in Thailand (Yak Yemen).
This breed has been gradually imported from the Middle East during the last 20 years. The growth rate is faster than native breeds. Because of its bigger caudex, it's called according to the place of plantation; for example, Yak Lopburi, Yak Singburi and Petch Mueang Kong (Korat). This breed has a very diverse character because it has been modified for a long time. The baby plant becomes so different from the original breed.

Arabicum : Yak-Saudi
It's usually called in short Arabicum. In fact, the name is used to identify its origin: Arab peninsula. The plants imported from Arab peninsula to Thailand can be categorized as follows:
- Arabicum - Yak-Saudi or shortly called Arabicum. This is the really big tree. In the past, the large and the more graceful plants mean more value but it was later modified to be smaller as in Arabicum Compact with glossy leaves or hairy leaves.
- Arabicum- RCN is a medium-sized bush tree with small medium-sized leaves.
- Arabicum-Thai-Socotranum, usually called ‘Thai Soco’, short giant, glossy leaves.
Yak Saudi is a big giant, Arabicum-RCNis a medium-sized bush tree, Thai-Soco is a short giant. The three are similar in terms of their small pink flowers but different in the shape of the trunk.
Nowadays, it's rare to find separate breed of the three in other farms but, as a breed collecter, Paisit farm plant them separately both for their seeds and seedlings. The mother cutting is original.
