- Common Name:
- Family: Amaryllidaceae J. St-Hil.
- Country of Origin: Rio de Janiero, Brazil
- Habitat: half shade, near rock outcrops
- Description: Bulb ca. 2.5–3.5 cm long, oval to round, subterraneous. Leaves up to 10–15(–20) × 1.2–2.3 cm, narrower at the base and broader at the distal third part, resulting in a slightly spatulated form, similarly green colored abaxially and adaxially. Inflorescence 1–7 flowers in different stages of maturity; scape 14–30 cm long; spathe with 2 free bracts, 1.4–3 cm long. Flowers with pedicels 0.8–3.2 cm long at anthesis, with different lengths in flowers of the same inflorescence; hypanthium tube 0.4–0.6 cm long, with many fimbriae, 0.1–0.2 cm long, above the junction of the filament with the tepals; tepals white with longitudinal rose colored to magenta stripes and yellowish green base; upper sepal 3.2–4.5 × 0.9–1.6 cm, lower sepals 3–4.2 × 0.5–1.3 cm, upper petals 3–4.3 × 0.4–0.9 cm, lowermost petal 2.7–3.7 × 0.2–0.4 cm. Stamen filaments 1.7–2.8 cm long, in two or three different lengths; pollen cream colored. Ovary trilocular, 0.2–0.4 cm long; style 2.7–3.6 cm long ascending distally; stigma trifid, with lobes 0.1–0.2 cm. Fruit trilocular, 1.4–2.1 × 0.4–0.8 cm dehiscent dry capsule, flat winged seeds 0.4–0.6 cm, dark brown to black. 2n = 22 chromosomes.2
The flowers of Hippeastrum idimae have a very unique morphology; they resemble closely Eithea blumenavia, in color, shape and in the corona type, being the smallest flowers found in Hippeastrum. The leaves are also narrow near the base, resembling the leaves of Eithea and of some Griffinia, but they grow more prostrate than in these genera. The main external morphological difference, however, lies in the seeds, which are round and with an expansion in Eithea and in Griffinia, flat and winged in Hippeastrum, with the exception of H. reticulatum Herbert (1824: sub t. 2475), that has completely round black seeds, without any expansion.2
- Culture: The species enjoy a rich and well-drained medium with lots of good filtered sunlight and fertilizer during the growing season. It has a winter dormancy in which it should be kept more dry.1
