Ten species of the subsection occur in Peninsular Malaysia ( T. alba , T. aseroe , T. chrysops , T. domei , T. fumida , T. grandiflora , T. malayana T. ornata , T. racemosa and T. aliasii ), with five of them ( T. alba , T. aliasii , T. aseroe , T. domei and T. ornata ) occurring in the state of Terengganu. Whereas most of these species are characterized by tepal appendages equal in size and shape, in T. aliasii the appendages of the inner tepals are longer than those of the outer tepals. In addition, the stamen connectives laterally raised to form a conspicuous interstaminal rib are a unique feature of T. aliasii that is not found in the other species of T. subsect. Odoardoa .
