Thai socotranum is a hybrid cross of Adenium arabicum and Adenium socotranum that was developed in Thailand many years ago Adenium socotranum is endemic from from the isolated island of Socotra in the Indian Ocean south of the Arabian peninsula and east of the Horn of Africa. For many years Socotra hosted a Soviet naval port and was off limits to most everyone, restricting the availability of plants and seeds. In recent years it is accessible, but the authorities are very protective of the natural resources and it is illegal to collect plant material of any type. Habitat and ecology:
A. socotranum, is the characteristic plant of rocky slopes, forming extensive patches of succulent shrubland in favourable locations. It grows among stones in grit or on other well drained soil. It displays several morphological and physiological adaptations to cope with the dry climate and fierce monsoonal winds. A. socotranum has a special cell sap cycling within the caudex which prevents overheating. Plant bodies are globular or columnar, with reduced surface areas that decrease transpiration. Glaucous wax surfaces and micro-anatomical epidermal emergences reflect radiation. The cycles of flowering and growth of A. socotranum are well adapted to the arid climate, in that it blooms after the rainy season in March-April and only when they are well past flowering do the fruits release their air-borne seeds, leaving them to be dispersed by the heavy monsoon storms. Then the dry season begins with (perhaps) a million adenium seedlings waiting for the next rainy season. The most common and regular associate in the Adenium shrub layer is the endemic Jatropha unicostata. This shrub is perhaps one of the most common species on Socotra. The close association between the two species is probably due to their apparent preference for, or ability to cope with, coarse rocky substrates. Numerous regeneration niches exist in such substrates, offering the seedlings protection from trampling and affording them some degree of shade. The seeds of both species germinate readily after rainfall. Furthermore both species are highly toxic to domestic livestock and as such are rarely browsed. -
