Hieronymiella

Hieronymiella is a little-known genus in the family Amaryllidaceae from semi-arid and arid regions on the eastern side of the Andes of northwestern Argentina and occasionally in southern Bolivia. The taxonomic treatment of this genus can be found on this PBS thread. DNA sequencing has found that it is a member of the Eustephieae tribe, sister to Chlidanthus, Eustephia, and Pyrolirion. The following cultivation information was provided by Mark Wilcox on the PBS list: Germinated seeds were planted in a 4-inch pot of Schultz's Professional Potting Soil Plus. The plants were grown under two 40 watt fluorescent bulbs for 16 hours each day. Average summer temperatures of ~75-80F (23-27 °C) and winter temperatures of ~65-73 (18-22 °C). Fertilization was performed for most watering from the bottom with a solution of 1/4 teaspoon of MiracleGro for Roses (18-24-16) to one gallon of water. Allow the soil to dry out between watering.

Hieronymiella marginata, formerly known as Hieronymiella argentina, occurs on parched, rocky terrain in extreme northern Argentina at altitudes nearing 3000 meters. In habitat, blooming occurs in November and December, just before the arrival of rains. On specimens shown by Arroyo-Leuenberger and Leuenberger (Herbertia 58, pp. 23-45, 2003-2004) basal leaf growth is present with bulbs in full bloom. Unlike them, the specimens shown here were hysteranthous, with no sign of leaf emergence during blooming. Also, coloration was uniquely orange, while the reference article reports other shades for this species. Photos taken by Andrew Wilson.
