It grows on the trunks of trees like + +Phoebe macrocarpa +C. Y.

Longifiles +Airy Shaw (1935: 25) + +, which is characterized by fasciculate inflorescence or solitary flower, and elongated filaments longer than anthers and spurred anther ( +Airy Shaw 1935 +, +1959 +). In the ser. +Longifiles +, except our new species, only two other species, viz., + +A. mannii + +and + +A. hosseana + +, have leaf blade with a round apex and tubular corolla with a glabrous external surface. These two species can be easily distinguished from our new species due to their very distinct morphology of the leaf blade and twigs, and corolla color and length.

+ + +We also tried to perform a microscopic comparison of leaf epidermis and pollen exine sculpture morphology of + +A. hongheensis + +(Fig. +3 A – D +) and + +A. mannii + +(Fig. +3 E – H +). The midveins of both + +Agapetes hongheensis + +and + +A. mannii + +are prominently elevated adaxially and abaxially. The veinlets of + +A. hongheensis + +are distinctly raised adaxially and form a reticulate pattern (Figs +1 J, K +, +3 C +), while the veinlets of + +A. mannii + +are not obvious (Figs +2 F, G +, +3 G +). The pollen grains of + +Agapetes hongheensis + +are sub-spheroidal tetrahedral tetrads with a diameter of 36.81 ± 1.47 μm, and the ornamentation of both apocolpium and mesocolpium are granulate (Fig. +3 A, B +). By comparison, the tetrads of + +A. mannii + +are of a smaller size, averaging 35.53 ± 1.54 μm in diameter, with a similar granulate ornamentation on both apocolpium and mesocolpium (Fig. +3 E, F +).
