Remarks: Info from http://www.nationaalherbarium.nl/Euphorbs/specM/MacarangaMPT.htm Caducous, or 1 to 2 persistent at apex. Leaves leathery, smooth below, the minor nerves not raised; withering yellow; main nerves with scattered, spreading, white whiskers. Staminate bracteoles acuminate. Seeds enclosed in thin, red aril......M. griffithiana Macaranga griffithiana is closely related to M. motleyana and M. constricta. These species share glaucous twigs, staminate bracteoles terminated by one small conical nectary, and 45-carpellate fruits with one disc-shaped glandular patch per locule. Macaranga constricta differs from the other two species in having much longer and erect inflorescences, and entire acuminate staminate bracteoles. Whitmore (1974) considered M. griffithiana a subspecies of M. motleyana. These species differ in a range of morphological and ecological characteristics. The leaves of M. griffithiana are shallowly dissected with short spreading cusps and broad sinuses, whereas in M. motleyana the leaves are long and ascending with deep narrow sinuses. The styles of M. griffithiana are very shortly connate and spreading from about 1/3 of the length, whereas they are connate to almost 2/3 of the length in M. motleyana. The bracteoles of the staminate inflorescences are only shortly and irregularly toothed in M. griffithiana whereas they are deeply and evenly pectinate in M. motleyana. The distributions of the two species do not overlap: M. motleyana is restricted to Borneo and M. griffithiana occurs from Indochina, south through the Thai-Malay peninsula to Sumatra. 参σlink | |
