I have seen T. donell-smithii at Philippines, specifically at Region 10 Bukidnon. This species is sparsely distributed throughout the country. This spp. is the subject of the master's thesis. I choose negative coz i tried to clone it using using stem cuttings, after 4 months no roots were formed. I suspected it has root-inhibiting subsbtance not to root, despite of shoots formed. Cuttings were applied with IBA and NAA. No rooting hormones better performed compare to treated cuttings.
