Monographs Details: Tococa obovata subsp. neblinensis Wurdack
Michelangeli, Fabián A. 2005. (Melastomataceae). Fl. Neotrop. Monogr. 98: 1-114. (Published by NYBG Press)
Description:Subspecies Description - Abaxial surface of the leaves foveolate; domatia rarely developed, immersed in the leaf blade, ovoid to elliptic, 0.4-1.0 X 0.3-0.6 cm.
Discussion:Tococa obovata is closely related to T. liesneri and T. oligantha, but it can be distinguished from both species by its large petals. Additionally, T. obovata can be distinguished from T. oligantha by the outer calyx, which is reduced in the latter and developed in the former. Tococa obovata has 5-nervate leaves, whereas T. liesneri has 3-nervate leaves.The two subspecies of T. obovata differ only in the surface of their leaves. Some of the duplicate specimens of subsp. neblinensis show foveolate leaves but without domatia. Given that it is not possible to determine from these specimens whether they all belonged to the same individual or not, it is impossible to say if the presence of domatia is polymorphic in the population or if smaller individuals or branches closer to the ground lack domatia (as in T. rotundifolia).The domatia present in T. obovata are extremely reduced compared to those of the remaining species of Tococa; however, detailed examination of some of them has revealed the presence of ants.
