}}Alrawia is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae (also treated as the family Hyacinthaceae).[1] It is native to north-eastern Iraq and Iran.[2]

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.[4] The tepals are violet with whitish lobe tips and are joined at the base for up to half their length.[3] The pedicels lengthen and turn upwards after flowers are fertilized; the black seeds are globular or ovate.[4]

Species

{{As of|2013|March}}, the World Checklist of Selected Plant Families recognized two species:[5]
  • Alrawia bellii (Baker) Perss. & Wendelbo

Flowers up to {{convert|1|cm|in|1|abbr=on}} long; tube one quarter the length of the whole flower; western Iran.[3]

  • Alrawia nutans (Wendelbo) Perss. & Wendelbo

Flowers slightly longer, up to {{convert|1.3|cm|in|1|abbr=on}} long; tube one half the length of the whole flower; north-east Iraq.[3]

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.[3]
