Brian,
Lucky you. I always loved that plant. I could never get one. Bought it twice but was something different. That strip down the middle of the leaf is only found on Hippeastrum reticulatum var. striatifolium. However, hybrids such as 'Mrs. Gardfield', 'Silhouette' ,'Bangkok Rose', etc., have leaves that are marked by a yellowish-white median strip.
If you get this beauty to flower, I know Mike (here on this post) and I would love to have some of the seeds.
