Description

Species of Alrawia grow from bulbs covered with a tunic that is grayish outside and often violet inside. They produce a single flowering stem (scape); the inflorescence consists of a raceme. Individual flowers are borne on a short stalk (pedicel) which is turned downwards when the flowers first appear.[3] The tepals are violet with whitish lobe tips and are joined at the base for up to half their length.[4] The pedicels lengthen and turn upwards after flowers are fertilized; the black seeds are globular or ovate.[3]

Species

As of March 2013, the World Checklist of Selected Plant Families recognized two species:[5]

  • Alrawia bellii (Baker) Perss. & Wendelbo
Flowers up to 1 cm (0.4 in) long; tube one quarter the length of the whole flower; western Iran.[4]
  • Alrawia nutans (Wendelbo) Perss. & Wendelbo
Flowers slightly longer, up to 1.3 cm (0.5 in) long; tube one half the length of the whole flower; north-east Iraq.[4]

Cultivation

Brian Mathew describes the species as "enthusiasts' plants", being "not very showy". They are said to be easy to cultivate in a bulb frame or alpine house but not to increase readily. As they occur naturally in regions with hot dry summers, the bulbs need to be dried out when dormant.[4]
