Re: hybrid
I managed to get some better photos of a D. aliciae flower, unfortunately the anthers were stuck together and it was literally closing before my eyes.
Obermeyer's* description of D. aliciae inflorescence:
"Inflorescence with the base of each scape exserted horizontally from the leafs rosette, subsequently erect, 15-40 cm. tall-firm, bearing 2-12 secund flowers; pedicel, up to 8 mm. long. Calyx-lobes c. 5 mm. long, broadly ovate, obtuse. Petals broadly obovate-cuneate, c. 10 mm. long purple. Stamens with the filaments flattened and the connective dilated. Styles forked from the base, the branches shortly 2-3-fid and dilated at the stigmatic apex. Capsule ovoid; seeds fusiform, with the testa extended on both sides."
No mention of hairs (or glands for that matter) on the scape.
Obermeyer* on D. capensis:
"Inflorescence with the leafless, axillary scape curved outwards below, about 25 cm. long, firm, bearing some small broad-based setae beside the glandular pubescence; pedicels up to 8 mm. long, ascending; flowers 15-30, secund, close together. Calyx-lobes c.5 mm long, sparsely setose. Petals broadly obovate, up to 15 mm. long, pink to reddish purple or mauve. Stamens short with a rhomboid connective, the locules diverging below. Styles divided from the base, stigma epical, swollen. Capsule oblong, 4 mm; seeds fusiform, 0.8 mm. long with the testa beaded-papillate, with an oblong pale extension of the testa at the apex, the basal extension small."
Note mention of setae and glandular pubescence on the scape.
I have no close up photos of D. capensis flowers or scapes but here are a few from BobZ's photofinder:

The red glands on the scape, pedicels and sepals doesn't appear to be prominent on D. capensis however if they are pale or colorless on the white flower form they may not be all that apparent in the photos.
Here are some shots of the presumed hybrid: note the red glands
Maybe there are some intermediate characteristics showing. Maybe not. More detailed photos of D. capensis are needed.
