Discussion
All the specimens examined up to the present were female, the pistillate flowers with rudimentary staminodia; no hermaphrodite flowers have been found among the collections cited in the monograph. Among the recent ones, however, an exceptional collection, Croat 35632, has male inflorescences with abundant staminate flowers and buds; from these, the following data are taken to supplement the original description.
Male flowers: Buds globose 2-2.5 mm diam., sericeous. Pedicels 2 mm long. Flattened calyx 6 mm diam., pentamerous, the lobes 2.1-2.4 mm long 1.8 mm wide ovate, acute, abaxially dense-sericeous, adaxially sparsely appressed puberulous. Stamens 10 subequal, the filaments 2-2.3 mm long, subulate, acute, proximally pubescent with long very thin flexuous hairs; anthers ellipsoid, obtuse at both ends, 2.2-2.4 mm long. Gynoecium reduced to five minute rudimentary carpels, the ovary about 0.2-0.3 mm, sterile, subsericeous, the style 0.7-0.8 mm subulate, erect. Disk 10-lobate the lobes rather short, densely tomentulose. In addition, emphasis should be made on the following features which may modify in part the original description of B. standleyana: follicles subsericeous, the trichomes rather short, 0.1-0.2 mm, dense and subappressed, only few near the margin and apex are somewhat longer up to 0.5(-0.9) mm, never prickly. Endocarp ellipsoid, attenuate at the attaching point, obtuse at apex. Seeds 2 mm long. Lateral blades with 17-22 pairs of secondary nerves. Stipules, as well as the stipels, bigeminate: four stipules at each opposite side of the stem; four stipels on the adaxial side of each leaf node. -
