Discussion:

In typical T. bolivarensis, known only from Estado Bolivar (Carrao-tepui, Steyermark 60856; Serra do Sol, Maguire & Maguire 40410), the branchlet internodes are sparsely glandular-setose and also thinly furfuraceous with elavate sessile glands, the hypanthium as well as the calyx is glandular-setose, and the leaf blades are persistently glandular-ciliate as well as plus-or-minus glandular-setulose marginally above and on the primary veins beneath. The mature calyx of both subspecies is obscurely 5-lobed, rather than strictly truncate as originally described.
