The red-flowered, unbranched Aloiampelos tenuior raceme emerging from above a leaf near a stem-tip is erect and loosely flowered. The green to pinkish pedicels are less than half as long as the flowers, presenting their perianths at roughly the same, slightly downward angle from bud stage at the top to the withered ones fruiting at the bottom. There are tiny, triangular bracts below the bases of the pedicels.
Uppermost buds are usually green-tipped, the feature more easily observed in yellow-flowering plants. The top buds tend to be angled upwards, not captured in the photo.
The cylindrical perianths open with slight additions of yellow at the segment tips, lost again as they turn into fruit covering. This yellow is partly upon three of the six anthers and filament tips exserted at a time.
The rarely branched racemes become 10 cm to 16 cm long and 4 cm in diameter. The perianths become from 11 mm to 14 mm long. The ovary is only 3 mm long, half that in diameter; the capsule elongates to 13 mm and 7 mm in diameter, its surface six-grooved (Van Wyk and Smith, 2003; Reynolds, 1974; iNaturalist).
