Hippeastrum psittacinum (Parrot Amaryllis) is a flowering perennial herbaceous bulbous plant, in the family Amaryllidaceae, native to Brazil.

Description 
Leaves, up to 8, strap like, length 45 cm. height 60 cm. Flowers, four trumpet shaped. Tubes short, green-white with spreading lobes, crimson stripes, and wavy crimson margins.

Taxonomy 
Described by John Bellenden Ker Gawler in 1817 as Amaryllis, but transferred to Hippeastrum by William Herbert in 1821.
‘The present is the fifth unrecorded Amaryllis from the  which has been published in this work out of the collection of Mr. Griffin.  To have been the first to bring within the sphere of science and into culture an equal number of plants, belonging to a same remote region, of a same genus, and all interesting, either on the score of curiosity or beauty, within little more than two years, has probably never before been the chance of any single collector in Europe.  The bulb was sent about 3 years ago by Mr. E. Woodford, from Rio Janeiro; and flowered in Mr. Griffin's hothouse at South Lambeth in March last.’ Ker Gawler
